A NEW LOOK AT THEORY
The monograph Maternal Care and Mental Health is in two parts. The first reviews the evid- ence regarding the adverse effects of maternal deprivation, the second discusses means for pre- venting it. What was missing, as several reviewers pointed out, was any explanation of how experi- ences subsumed under the broad heading of ma- ternal deprivation could have the effects on per- sonality development of the kinds claimed. The reason for this omission was simple: the data
69/362
? ? ? were not accommodated by any theory then cur- rent and in the brief time of my employment by the World Health Organisation there was no pos- sibility of developing a new one.
The child's tie to his mother
At that time it was widely held that the reason a child develops a close tie to his mother is that she feeds him. Two kinds of drive are postulated, primary and secondary. Food is thought of as primary; the personal relationship, referred to as 'dependency', as secondary. This theory did not seem to me to fit the facts. For example, were it true, an infant of a year or two should take read- ily to whomever feeds him and this clearly was not the case. An alternative theory, stemming from the Hungarian school of psychoanalysis, postulated a primitive object relation from the beginning. In its best-known version, however, the one advocated by Melanie Klein, mother's breast is postulated as the first object, and the greatest emphasis is placed on food and orality and on the infantile nature of 'dependency'. None of these features matched my experience of children.
70/362
? ? ? But if the current dependency theories were in- adequate, what was the alternative?
During the summer of 1951 a friend mentioned to me the work of Lorenz on the following re- sponses of ducklings and goslings. Reading about this and related work on instinctive behaviour re- vealed a new world, one in which scientists of high calibre were investigating in non-human species many of the problems with which we were grappling in the human, in particular the relat- ively enduring relationships that develop in many species, first between young and parents and later between mated pairs, and some of the ways in which these developments can go awry. Could this work, I asked myself, cast light on a problem central to psychoanalysis, that of 'instinct' in humans?
Next followed a long phase during which I set about trying to master basic principles and to ap- ply them to our problems, starting with the nature of the child's tie to his mother. Here Lorenz's work on the following response of duck- lings and goslings (Lorenz, 1935) was of special interest. It showed that in some animal species a strong bond to an individual motherfigure could develop without the intermediary of food: for
71/362
? ? ? these young birds are not fed by parents but feed themselves by catching insects. Here then was an alternative model to the traditional one, and one that had a number of features that seemed pos- sibly to fit the human case. Thereafter, as my grasp of ethological principles increased and I ap- plied them to one clinical problem after another, I became increasingly confident that this was a promising approach. Thus, having adopted this novel point of view, I decided to 'follow it up through the material as long as the application of it seems to yield results' (to borrow a phrase of Freud's).
From 1957, when The Nature of the Child's Tie to his Mother was first presented, through 1969 when Attachment appeared, until 1980 with the publication of Loss I concentrated on this task. The resulting conceptual framework2 is designed to accommodate all those phenomena to which Freud called attention--for example love rela- tions, separation anxiety, mourning, defence, an- ger, guilt, depression, trauma, emotional detach- ment, sensitive periods in early life--and so to of- fer an alternative to the traditional metapsycho- logy of psychoanalysis and to add yet another to the many variants of the clinical theory now
72/362
? ? ? extant. How successful these ideals will prove only time will tell.
As Kuhn has emphasized, any novel conceptual framework is difficult to grasp, especially so for those long familiar with a previous one. Of the many difficulties met with in understanding the framework advocated, I describe only a few. One is that, instead of starting with a clinical syn- drome of later years and trying to trace its origins retrospectively, I have started with a class of childhood traumata and tried to trace the se- quelae prospectively. A second is that, instead of starting with the private thoughts and feelings of a patient, as expressed in free associations or play, and trying to build a theory of personality development from those data, I have started with observations of the behaviour of children in cer- tain sorts of defined situation, including records of the feelings and thoughts they express, and have tried to build a theory of personality devel- opment from there. Other difficulties arise from my use of concepts such as control system (in- stead of psychic energy) and developmental path- way (instead of libidinal phase), which, although now firmly established as key concepts in all the biological sciences, are still foreign to the
73/362
? ? ? thinking of a great many psychologists and clinicians.
Having discarded the secondary-drive, depend- ency theory of the child's tie to his mother, and also the Kleinian alternative, a first task was to formulate a replacement. This led to the concept of attachment behaviour with its own dynamics distinct from the behaviour and dynamics of either feeding or sex, the two sources of human motivation for long widely regarded as the most fundamental. Strong support for this step soon came from Harlow's finding that, in another primate species--rhesus macaques--infants show a marked preference for a soft dummy 'mother', despite its providing no food, to a hard one that does provide it (Harlow and Zimmermann, 1959).
Attachment behaviour is any form of behaviour that results in a person attaining or maintaining proximity to some other clearly identified indi- vidual who is conceived as better able to cope with the world. It is most obvious whenever the person is frightened, fatigued, or sick, and is as- suaged by comforting and caregiving. At other times the behaviour is less in evidence. Neverthe- less for a person to know that an attachment fig- ure is available and responsive gives him a strong
74/362
? ? ? and pervasive feeling of security, and so encour- ages him to value and continue the relationship. Whilst attachment behaviour is at its most obvi- ous in early childhood, it can be observed throughout the life cycle, especially in emergen- cies. Since it is seen in virtually all human beings (though in varying patterns), it is regarded as an integral part of human nature and one we share (to a varying extent) with members of other spe- cies. The biological function attributed to it is that of protection. To remain within easy access of a familiar individual known to be ready and willing to come to our aid in an emergency is clearly a good insurance policy--whatever our age.
By conceptualizing attachment in this way, as a fundamental form of behaviour with its own in- ternal motivation distinct from feeding and sex, and of no less importance for survival, the beha- viour and motivation are accorded a theoretical status never before given them--though parents and clinicians alike have long been intuitively aware of their importance. As already emphas- ized, the terms 'dependency' and 'dependency need' that have hitherto been used to refer to them have serious disadvantages. In the first
75/362
? ? ? place 'dependency' has a perjorative flavour; in the second it does not imply an emotionally charged relationship to one or a very few clearly preferred individuals; and in the third no valu- able biological function has ever been attributed to it.
It is now 30 years since the notion of attach- ment was first advanced as a useful way of con- ceptualizing a form of behaviour of central im- portance not only to clinicians and to develop- mental psychologists but to every parent as well. During that time attachment theory has been greatly clarified and amplified. The most notable contributors have been Robert Hinde who, in ad- dition to his own publications (e. g. 1974), has constantly guided my own thinking, and Mary Ainsworth who, starting in the late 50s, has pion- eered empirical studies of attachment behaviour both in Africa (1963, 1967) and in the USA (Ainsworth and Wittig, 1969; Ainsworth et al. , 1978), and has also helped greatly to develop the- ory (e. g. 1969, 1982). Her work, together with that of her students and others influenced by her (which has expanded dramatically since this lec- ture was given and is described in some detail in Lecture 7), has led attachment theory to be
76/362
? ? ? widely regarded as probably the best supported theory of socio-emotional development yet avail- able (Rajecki, Lamb, and Obmascher, 1978; Rut- ter, 1980; Parkes and Stevenson-Hinde, 1982; Sroufe, 1986).
Because my starting point in developing theory was observations of behaviour, some clinicians have assumed that the theory amounts to no more than a version of behaviourism. This mis- take is due in large part to the unfamiliarity of the conceptual framework proposed and in part to my own failure in early formulations to make clear the distinction to be drawn between an at- tachment and attachment behaviour. To say of a child (or older person) that he is attached to, or has an attachment to, someone means that he is strongly disposed to seek proximity to and con- tact with that individual and to do so especially in certain specified conditions. The disposition to behave in this way is an attribute of the attached person, a persisting attribute which changes only slowly over time and which is unaffected by the situation of the moment. Attachment behaviour, by contrast, refers to any of the various forms of behaviour that the person engages in from time
77/362
? ? ? to time to obtain and/or maintain a desired proximity.
There is abundant evidence that almost every child habitually prefers one person, usually his mother-figure, to whom to go when distressed but that, in her absence, he will make do with someone else, preferably someone whom he knows well. On these occasions most children show a clear hierarchy of preference so that, in extremity and with no one else available, even a kindly stranger may be approached. Thus, whilst attachment behaviour may in differing circum- stances be shown to a variety of individuals, an enduring attachment, or attachment bond, is confined to very few. Should a child fail to show such clear discrimination, it is likely he is severely disturbed.
The theory of attachment is an attempt to ex- plain both attachment behaviour, with its episod- ic appearance and disappearance, and also the enduring attachments that children and other in- dividuals make to particular others. In this theory the key concept is that of behavioural system. This is conceived on the analogy of a physiologic- al system organized homeostatically to ensure that a certain physiological measure, such as
78/362
? ? ? body temperature or blood pressure, is held between appropriate limits. In proposing the concept of a behavioural system to account for the way a child or older person maintains his re- lation to his attachment figure between certain limits of distance or accessibility, no more is done than to use these well-understood principles to account for a different form of homeostasis, namely one in which the set limits concern the organism's relation to clearly identified persons in, or other features of, the environment and in which the limits are maintained by behavioural instead of physiological means.
In thus postulating the existence of an internal psychological organization with a number of highly specific features, which include represent- ational models of the self and of attachment fig- ure(s), the theory proposed can be seen as having all the same basic properties as those that charac- terize other forms of structural theory, of which the variants of psychoanalysis are some of the best known, and that differentiate them so sharply from behaviourism in its many forms. Historically attachment theory was developed as a variant of object-relations theory.
79/362
? ? ? The reason why in this account I have given so much space to the concept and theory of attach- ment is that, once those principles are grasped, there is little difficulty in understanding how the many other phenomena of central concern to clinicians are explained within the framework proposed.
Separation anxiety
For example, a new light is thrown on the prob- lem of separation anxiety, namely anxiety about losing, or becoming separated from, someone loved. Why 'mere separation' should cause anxi- ety has been a mystery. Freud wrestled with the problem and advanced a number of hypotheses (Freud, 1926; Strachey, 1959). Every other lead- ing analyst has done the same. With no means of evaluating them, many divergent schools of thought have proliferated.
The problem lies, I believe, in an unexamined assumption, made not only by psychoanalysts but by more traditional psychiatrists as well, that fear is aroused in a mentally healthy person only in situations that everyone would perceive as in- trinsically painful or dangerous, or that are per- ceived so by a person only because of his having
80/362
? ? ? become conditioned to them. Since fear of separ- ation and loss does not fit this formula, analysts have concluded that what is feared is really some other situation; and a great variety of hypotheses have been advanced.
The difficulties disappear, however, when an ethological approach is adopted. For it then be- comes evident that man, like other animals, re- sponds with fear to certain situations, not be- cause they carry a high risk of pain or danger, but because they signal an increase of risk. Thus, just as animals of many species, including man, are disposed to respond with fear to sudden move- ment or a marked change in level of sound or light because to do so has survival value, so are many species, including man, disposed to re- spond to separation from a potentially caregiving figure and for the same reasons.
When separation anxiety is seen in this light, as a basic human disposition, it is only a small step to understand why it is that threats to abandon a child, often used as a means of control, are so very terrifying. Such threats, and also threats of suicide by a parent, are, we now know, common causes of intensified separation anxiety. Their ex- traordinary neglect in traditional clinical theory
81/362
? ? ? is due, I suspect, not only to an inadequate theory of separation anxiety but to a failure to give prop- er weight to the powerful effects, at all ages, of real-life events.
Not only do threats of abandonment create in- tense anxiety but they also arouse anger, often also of intense degree, especially in older children and adolescents. This anger, the function of which is to dissuade the attachment figure from carrying out the threat, can easily become dys- functional. It is in this light, I believe, that we can understand such absurdly paradoxical behaviour as the adolescent, reported by Burnham (1965), who, having murdered his mother, exclaimed, 'I couldn't stand to have her leave me. '
Other pathogenic family situations are readily understood in terms of attachment theory. One fairly common example is when a child has such a close relationship with his mother that he has difficulty in developing a social life outside the family, a relationship sometimes described as symbiotic. In a majority of such cases the cause of the trouble can be traced to the mother who, hav- ing grown up anxiously attached as a result of a difficult childhood, is now seeking to make her own child her attachment figure. So far from the
82/362
? ? ? child being over-indulged, as is sometimes asser- ted, he is being burdened with having to care for his own mother. Thus, in these cases, the normal relationship of attached child to caregiving par- ent is found to be inverted.
Mourning
Whilst separation anxiety is the usual response to a threat or some other risk of loss, mourning is the usual response to a loss after it has occurred. During the early years of psychoanalysis a num- ber of analysts identified losses, occurring during childhood or in later life, as playing a causal role in emotional disturbance, especially in depressive disorders; and by 1950 a number of theories about the nature of mourning, and other re- sponses to loss, had been advanced. Moreover, much sharp controversy had already been en- gendered. This controversy, which began during the 30s, arose from the divergent theories about infant development that had been elaborated in Vienna and London. Representative examples of the different points of view about mourning are those expressed in Helene Deutsch's Absence of Grief (1937) and Melanie Klein's Mourning and its Relation to Manic-Depressive States (1940).
83/362
? ? ? Whereas Deutsch held that, due to inadequate psychic development, children are unable to mourn, Klein held that they not only can mourn but do. In keeping with her strong emphasis on feeding, however, she held that the object mourned was the lost breast; and, in addition, she attributed a complex fantasy-life to the in- fant. Opposite though these theoretical positions are, both were constructed using the same meth- odology, namely by inferences about earlier phases of psychological development based on observations made during the analysis of older, and emotionally disturbed, subjects. Neither the- ory had been checked by direct observation of how ordinary children of different ages respond to a loss.
Approaching the problem prospectively, as I did, led me to different conclusions. During the early 1950s Robertson and I had generalized the sequence of responses seen in young children during temporary separation from mother as those of protest, despair, and detachment (Robertson and Bowlby, 1952). A few years later, when reading a study by Marris (1958) of how widows respond to loss of husband, I was struck by the similarity of the responses he describes to
84/362
? ? ? those of young children. This led me to a system- atic study of the literature on mourning, espe- cially the mourning of healthy adults. The se- quence of responses that commonly occur, it be- came clear, was very different from what clinical theorists had been assuming. Not only does mourning in mentally healthy adults last far longer than the six months often suggested in those days, but several component responses widely regarded as pathological were found to be common in healthy mourning. These include an- ger, directed at third parties, the self, and some- times at the person lost, disbelief that the loss has occurred (misleadingly termed denial), and a tendency, often though not always unconscious, to search for the lost person in the hope of re- union. The clearer the picture of mourning re- sponses in adults became, the clearer became their similarities to the responses observed in childhood. This conclusion, when first advanced (Bowlby, 1960, 1961), was much criticized; but it has now been amply supported by a number of subsequent studies (e. g. Parkes, 1972; Kliman, 1965; Furman, 1974; Raphael, 1982).
Once an accurate picture of healthy mourning has been obtained, it becomes possible to identify
85/362
? ? ? features that are truly indicative of pathology. It becomes possible also to discern many of the con- ditions that promote healthy mourning and those that lead in a pathological direction. The belief that children are unable to mourn can then be seen to derive from generalizations that had been made from the analyses of children whose mourning had followed an atypical course. In many cases this had been due either to the child never having been given adequate information about what had happened, or else to there having been no one to sympathize with him and help him gradually come to terms with his loss, his yearning for his lost parent, his anger, and his sorrow.
Defensive processes
The next step in this reformulation of theory was to consider how defensive processes could best be conceptualized, a crucial step since defensive pro- cesses have always been at the heart of psycho- analytic theory. Although as a clinician I have in- evitably been concerned with the whole range of defences, as a research worker I have directed my attention especially to the way a young child be- haves towards his mother after a spell in a
86/362
? ? ? hospital or residential nursery unvisited. In such circumstances it is common for a child to begin by treating his mother almost as though she were a stranger, but then, after an interval, usually of hours or days, to become intensely clinging, anxious lest he lose her again, and angry with her should he think he may. In some way all his feel- ing for his mother and all the behaviour towards her we take for granted, keeping within range of her and most notably turning to her when frightened or hurt, have suddenly vanished--only to reappear again after an interval. That was the condition James Robertson and I termed detach- ment and which we believed was a result of some defensive process operating within the child.
Whereas Freud in his scientific theorizing felt confined to a conceptual model that explained all phenomena, whether physical or biological, in terms of the disposition of energy, today we have available conceptual models of much greater vari- ety. Many draw on such interrelated concepts as organization, pattern, and information; while the purposeful activities of biological organisms can be conceived in terms of control systems struc- tured in certain ways. With supplies of physical energy available to them, these systems become
87/362
? ? ? active on receipt of certain sorts of signal and in- active on receipt of signals of other sorts. Thus the world of science in which we live is radically different from the world Freud lived in at the turn of the century, and the concepts available to us immeasurably better suited to our problems than were the very restricted ones available in his day.
If we return now to the strange detached beha- viour a young child shows after being away for a time with strange people in a strange place, what is so peculiar about it is, of course, the absence of attachment behaviour in circumstances in which we would confidently expect to see it. Even when he has hurt himself severely, such a child shows no sign of seeking comfort. Thus signals that would ordinarily activate attachment behaviour are failing to do so. This suggests that in some way and for some reason these signals are failing to reach the behavioural system responsible for attachment behaviour, that they are being blocked off, and the behavioural system itself is thereby immobilized. What this means is that a system controlling such crucial behaviour as at- tachment can in certain circumstances be rendered either temporarily or permanently
88/362
? ? ? incapable of being activated, and with it the whole range of feeling and desire that normally accompanies it is rendered incapable of being aroused.
In considering how this deactivation might be effected I turn to the work of the cognitive psy- chologists (e. g. Norman, 1976; Dixon, 1971, 1981) who, during the past 20 years, have revolution- ized our knowledge of how we perceive the world and how we construe the situations we are in. Amongst much else that is clinically congenial, this revolution in cognitive theory not only gives unconscious mental processes the central place in mental life that analysts have always claimed for them, but presents a picture of the mental appar- atus as being well able to shut off information of certain specified types and of doing so selectively without the person being aware of what is happening.
In the emotionally detached children described earlier and also, I believe, in adults who have de- veloped the kind of personality that Winnicott (1960) describes as 'false self' and Kohut (1977) as 'narcissistic', the information being blocked off is of a very special type. So far from its being the routine exclusion of irrelevant and potentially
89/362
? ? ? distracting information that we engage in all the time and that is readily reversible, what are being excluded in these pathological conditions are the signals, arising from both inside and outside the person, that would activate their attachment be- haviour and that would enable them both to love and to experience being loved. In other words, the mental structures responsible for routine se- lective exclusion are being employed--one might say exploited--for a special and potentially patho- logical purpose. This form of exclusion I refer to--for obvious reasons--as defensive exclusion, which is, of course, only another way of describ- ing repression. And, just as Freud regarded re- pression as the key process in every form of de- fence, so I see the role of defensive exclusion.
3 A fuller account of this, an information-processing approach to the problem of defence, in which de- fences are classified into defensive processes, de- fensive beliefs, and defensive activities, is given in an early chapter of Loss (Bowlby, 1980).
An alternative framework
During the time it has taken to develop the con- ceptual framework described here Margaret Mahler has been concerned with many of the
90/362
? ? ? same clinical problems and some of the same fea- tures of children's behaviour; and she also has been developing a revised conceptual framework to account for them, set out fully in her book The Psychological Birth of the Human Infant (Mahler, Pine, and Bergman, 1975). To compare alternative frameworks is never easy, as Kuhn (1962) emphasizes, and no attempt is made to do so here. Elsewhere (e. g. Bowlby, 1981) I describe what I believe to be some of the strengths of the framework I favour, including its close related- ness to empirical data, both clinical and develop- mental, and its compatibility with current ideas in evolutionary biology and neurophysiology; whilst what I see as the shortcomings of Mahler's framework are trenchantly criticized by Peterfre- und (1978) and Klein (1981).
In brief, Mahler's theories of normal develop- ment, including her postulated normal phases of autism and symbiosis, are shown to rest not on observation but on preconceptions based on tra- ditional psychoanalytic theory and, in doing so, to ignore almost entirely the remarkable body of new information about early infancy that has been built up from careful empirical studies over the past two decades. Although some of the
91/362
? ? ? clinical implications of Mahler's theory are not very different from those of attachment theory, and her concept of return to base to 'refuel' is similar to that of use of an attachment figure as a secure base from which to explore, the key con- cepts with which the two frameworks are built are very different.
RESEARCH
Nothing has been so rewarding as the immense amount of careful research to which the early work on maternal deprivation has given rise. The literature is now enormous and far beyond the compass of an account of this sort to summarize. Fortunately, moreover, it is unnecessary since a comprehensive and critical review of the field has been published by Rutter (1979) who concludes by referring to the 'continuing accumulation of evidence showing the importance of deprivation and disadvantage on children's psychological de- velopment' and expressing the view that the ori- ginal arguments 'have been amply confirmed'. A principal finding of recent work is the extent to which two or more adverse experiences interact so that the risk of a psychological disturbance fol- lowing is multiplied, often many times over. An
92/362
? ? ? example of this interactive effect of adverse ex- periences is seen in the findings of Brown and Harris (1978) derived from their studies of de- pressive disorders in women. (During the last decade this group has published many further findings of the greatest interest, see Harris (1988). )
Not only is there this strongly interactive effect of adverse experiences but there is an increased likelihood for someone who has had one adverse experience to have another. For example, 'people brought up in unhappy or disrupted homes are more likely to have illegitimate children, to be- come teenage mothers, to make unhappy mar- riages, and to divorce' (Rutter, 1979). Thus ad- verse childhood experiences have effects of at least two kinds. First they make the individual more vulnerable to later adverse experiences. Se- condly they make it more likely that he or she will meet with further such experiences. Whereas the earlier adverse experiences are likely to be wholly independent of the agency of the individual con- cerned, the later ones are likely to be the con- sequences of his or her own actions, actions that spring from those disturbances of personality to which the earlier experiences have given rise.
93/362
? ? ? Of the many types of psychological disturbance that are traceable, at least in part, to one or an- other pattern of maternal deprivation, the effects on parental behaviour and thereby on the next generation are potentially the most serious. Thus a mother who, due to adverse experiences during childhood, grows up to be anxiously attached is prone to seek care from her own child and thereby lead the child to become anxious, guilty, and perhaps phobic (see review in Bowlby, 1973). A mother who as a child suffered neglect and fre- quent severe threats of being abandoned or beaten is more prone than others to abuse her child physically (DeLozier, 1982), resulting in the adverse effects on the child's developing person- ality recorded, amongst others, by George and Main (1979). Systematic research into the effects of childhood experiences on the way mothers and fathers treat their children has only just begun and seems likely to be one of the most fruitful of all fields for further research. Other research leads are described in a recent symposium edited by Parkes and Stevenson-Hinde (1982).
My reason for giving so much space in this ac- count to the development of theory is not only because it has occupied so much of my time but
94/362
? ? ? because, as Kurt Lewin remarked long ago, 'There is nothing so practical as a good theory', and, of course, nothing so handicapping as a poor one. Without good theory as a guide, research is likely to be difficult to plan and to be unproduct- ive, and findings are difficult to interpret. Without a reasonably valid theory of psychopath- ology, therapeutic techniques tend to be blunt and of uncertain benefit. Without a reasonably valid theory of aetiology, systematic and agreed measures of prevention will never be supported. My hope is that in the long term the greatest value of the theory proposed may prove to be the light it throws on the conditions most likely to promote healthy personality development. Only when those conditions are clear beyond doubt will parents know what is best for their children and will communities be willing to help them provide it.

PSYCHOANALYSIS AS ART AND SCIENCE
During the summer of 1978 I was invited to give a number of lectures in Canada. Among the in- vitations was one from the Canadian Psycho- analytic Society to give their academic lecture to the annual meeting of the Society to be held in Quebec City. The topic I selected is one which had concerned me for some years, and about which I believe there is still a great deal of con- fused thinking.
In taking as my theme psychoanalysis as art and science I want to draw attention to what I believe to be two very different aspects of our discip- line--the art of psychoanalytic therapy and the science of psychoanalytic psychology--and in do- ing so to emphasize, on the one hand, the dis- tinctive value of each and, on the other, the gulf that divides them--in regard both to the contrast- ing criteria by which each should be judged and
? 97/362
? ? ? the very different mental outlook that each de- mands. In emphasizing these distinctions, I can- not help regretting that the word psychoanalysis came early to be used ambiguously as Freud him- self described it. 'While it was originally the name of a particular therapeutic method', he writes in his autobiography (1925), 'it has now also become the name of a science--the science of unconscious mental processes'.
The distinction I am drawing, of course, is not confined to psychoanalysis. It applies in every field in which the practice of a profession or a craft gives birth to a body of scientific know- ledge--the blacksmith to metallurgy, the civil en- gineer to soil mechanics, the farmer to plant physiology, and the physician to the medical sci- ences. In each of these fields the roles differenti- ate. On the one hand are the practitioners, on the other the scientists, with a limited number of in- dividuals attempting to combine both roles. As history shows, this process of differentiation of- ten proves painful and misunderstandings are frequent. Since I believe differentiation is bound to come also in our own field, and is perhaps already overdue, let us consider some of the diffi- culties and misunderstandings to which it may all
98/362
? ? ? too easily give rise in the hope of avoiding them or mitigating their consequences.
I start by contrasting the roles of practitioner and research scientist and do so under three headings, using the case of medicine as an example.
FOCUS OF STUDY
The aim of the practitioner is to take into account as many aspects as he can of each and every clin- ical problem with which he is called upon to deal. This requires him not only to apply any scientific principle that appears relevant but also to draw on such personal experience of the condition as he may have acquired and, especially, to attend to that unique combination of features met with in each patient. Knowing how greatly patients dif- fer, the experienced clinician recognizes that a form of treatment well suited to one would be totally inappropriate to another.
Taking all factors into account and giving each its due weight is the art of clinical judgement.
The outlook of the research scientist is quite different. In his efforts to discern general pat- terns underlying individual variety he ignores the particular and strives to simplify, risking thereby
99/362
? ? ? over- simplification. If he is wise he will probably concentrate attention on a limited aspect of a limited problem. If in making his selection he proves sagacious, or simply lucky, he may not only elucidate the problem selected but also de- velop ideas applicable to a broader range. If his selection proves unwise or unlucky he may merely end up knowing more and more about less and less. That is the risk every researcher runs. The art of research lies in selecting a limited manageable problem and the methods that will best help solve it. This brings me to my second point.
MODES OF ACQUIRING INFORMATION
In the methods available to him for acquiring in- formation the practitioner has certain great ad- vantages over the research scientist but also cer- tain great disadvantages. Let us start with the advantages.
In his role of giving help the practitioner is per- mitted access to information of certain kinds that remain closed to the scientist: as a friend of mine is fond of saving, it's only surgeons who are al- lowed to cut you open to see what's inside. In an analogous way it is only by treating a patient

? ? ? therapeutically that a psychoanalyst is given ac- cess to much of importance going on in a person's mind. In both professions, moreover, practition- ers are permitted to intervene in specified ways and privileged to observe what the consequences of such interventions are. These are immense ad- vantages and psychoanalysts have not been slow to exploit them.
Yet no science can prosper for long without en- listing new methods to cross-check on observa- tions made and on hypotheses born of older methods. Here the research scientist is likely to have the advantage. In the medical sciences, physiologists and pathologists have made im- mense advances by means of animal experi- ments, tissue culture, biochemical analyses, and a thousand other ingenious techniques. Indeed, it is a hallmark of a creative scientist that he devises new means by which phenomena, perhaps already well studied by other methods, can be ob- served in some new way.
It is in this area, I believe, that the ambiguous use of the word psychoanalysis has done greatest harm. For it has led some analysts to suppose that the only method of enquiry appropriate for the advancement of psychoanalytic science is that
101/362
? ? ? of treating a patient psychoanalytically. Since I believe this to be a profound misunderstanding I shall be saying a good deal more about it. Before doing so, however, I want to say a word about the place of scepticism and faith in the respective worlds of scientist and practitioner.
SCEPTICISM AND FAITH
In his day-to-day work it is necessary for a scient- ist to exercise a high degree of criticism and self- criticism: and in the world he inhabits neither the data nor the theories of a leader, however ad- mired personally he may be, are exempt from challenge and criticism. There is no place for authority.
The same is not true in the practice of a profes- sion. If he is to be effective a practitioner must be prepared to act as though certain principles and certain theories were valid; and in deciding which to adopt he is likely to be guided by those with ex- perience from whom he learns. Since, moreover, there is a tendency in all of us to be impressed whenever the application of a theory appears to have been successful, practitioners are at special risk of placing greater confidence in a theory than the evidence available may justify.
102/362
? ? ? From the standpoint of clinical practice this is no bad thing. On the contrary, there is abundant evidence that the great majority of patients are helped by the faith and hope that a practitioner brings to his work; whilst it is often the very lack of these qualities that makes so many excellent research workers sadly ill-suited to be therapists.
Yet, though faith in the validity of particular data and in particular theories is out of place in a scientist, I do not wish to imply that he is nothing but a sceptic. On the contrary, his whole way of living is founded on faith, faith that in the long run the best route to reliable knowledge is the ap- plication of scientific method.
I am, of course, aware that there are many psy- choanalysts who do not share this faith and who believe that the types of problem with which we deal lie far outside the scope of science. This is a view I respect, though I do not share: nor, of course, did Freud. Yet even those of us who are most enthusiastic about applying scientific meth- od in our field must recognize that there may well be problems that it can never solve. We simply do not know. Our task, as I see it, is to apply our method as skilfully as we can, on the one hand believing that the area of reliable knowledge will
103/362
? ? ? thereby be expanded and, on the other, accepting that there are likely always to remain still greater areas lying beyond the scope of any existing mode of scientific enquiry.
To many of you, I am afraid, engaged in thera- peutic practice but also hoping to contribute to the advance of psychoanalytic science, the con- trasts I am drawing between the roles of practi- tioner and scientist will hardly be welcome. Yet I believe that it is only by recognizing these differ- ences and acting accordingly that the strengths of each role can be used to fullest advantage--or that any one person can occupy both of them with any hope of success. As practitioners we deal in complexity; as scientists we strive to simplify. As practitioners we use theory as a guide; as sci- entists we challenge that same theory. As practi- tioners we accept restricted modes of enquiry; as scientists we enlist every method we can.
Earlier I remarked on the need for every devel- oping science to devise new methods for obtain- ing data. The reason for this is that, however pro- ductive any one method may be, it is bound to have its limitations, whilst there is always a pro- spect that some other method may compensate for them. Thus the new method may be in no way
104/362
? ? ? superior to the old; indeed it may have great lim- itations. Its usefulness lies simply in the fact that its strengths and its limitations are different. Per- haps I can illustrate the point by reference to my own work.
When I qualified in psychoanalysis in 1937, members of the British Society were occupied in exploring the fantasy worlds of adults and chil- dren, and it was regarded as almost outside the proper interest of an analyst to give systematic attention to a person's real experiences. That was a time when Freud's famous about-turn of 1897 regarding the aetiology of hysteria1 had led to the view that anyone who places emphasis on what a child's real experiences may have been, and per- haps still are being, was regarded as pitifully nai? ve. Almost by definition it was assumed that anyone interested in the external world could not be interested in the internal world, indeed was al- most certainly running away from it.
To me as a biologist this contrast of internal with external, of organism with environment, never appealed. Furthermore, as a psychiatrist engaged in work with children and families and deeply influenced by the insights of two analytic- ally oriented social workers, I was daily
105/362
? ? ? confronted with the impact on children of the emotional problems from which their parents suffered. Here are two examples I still recall vividly. In one a father was deeply concerned about his 8-year-old son's masturbation and in reply to my enquiries explained how, whenever he caught him with his hand on his genitals, he put him under a cold tap. This led me to ask fath- er whether he himself had ever had any worry about masturbation, and he launched into a long and pathetic tale of how he had battled with the problem all his life. In another case a mother's punitive treatment of her 3-year-old's jealousy of the new baby was as quickly traced to the prob- lem she had always had with her own jealousy of a younger brother.
Observations of these kinds led me to conclude that it is just as necessary for analysts to study the way a child is really treated by his parents as it is to study the internal representations he has of them, indeed that the principal focus of our studies should be the interaction of the one with the other, of the internal with the external. Be- lieving that that would be possible only if we had far more systematic knowledge about the effects on a child of the experiences he has during his
106/362
? ? ? early years within his family, I concentrated my attention on this area. The reasons that I selected as my special field of study the removal of a young child from his home to a residential nurs- ery or hospital rather than the broader field of parent-child interaction were several. First it was an event that I believed could have serious ill ef- fects on a child's personality development. Se- condly there could be no debate whether it had occurred or not, in this regard contrasting strongly with the difficulty of obtaining valid in- formation about how a parent treats a child. Thirdly it appeared to be a field in which prevent- ive measures might be possible. And perhaps I should add, fourthly, that I was stimulated by the sheer incredulity with which my views were met by some, though by no means all, of my col- leagues when I first advanced them just before the war.
The results of our ensuing studies, undertaken by two researchers both of whom subsequently qualified as analysts, James Robertson and Christoph Heinicke, are now well-known; and I believe them to have had a significant effect on psychoanalytic thinking. The points I wish to make now, however, concern research strategy.
107/362
? ? ? Despite the pioneer work of such distinguished analysts as Anna Freud, Rene? Spitz, Ernst Kris, Margaret Mahler, and others, for long there has been a tendency in analytic circles to regard the direct observation of young children and the re- cording of what they say as no more than an aux- iliary method of research, the results of which are of interest when they confirm conclusions already reached by the traditional method of treating pa- tients but which are unable to contribute any- thing original. The notion that the direct observa- tion of children--in and out of the family set- ting--is not only a valuable method for advancing psychoanalytic science but is indispensable to it has been slow to be accepted.
The principal contributions of these direct studies, I believe, are to cast light on how chil- dren develop emotionally and socially, on what the ranges of variation are in respect to a very large number of relevant parameters, and what types of family experience tend to influence chil- dren to develop in one way rather than another. Let me give some examples of findings by col- leagues working in our sister sciences of ethology and developmental psychology that I believe to be highly germane to our clinical understanding.
108/362
? ? ? The first example is from the work of Mary Sal- ter Ainsworth (1977), formerly at Johns Hopkins University and now at the University of Virginia. Trained initially as a clinical psychologist, Mary Ainsworth worked with us at the Tavistock dur- ing the early 50s and then spent a couple of years studying mothers and infants in Uganda. Her definitive study has concerned the development of mother-infant interaction during the first year of life in white middle-class homes in Baltimore, Maryland. She has had a personal analysis and is keenly alive to the types of problem analysts re- gard as important.
During her study of mothers and infants in Uganda Ainsworth was struck how infants, once mobile, commonly use mother as a base from which to explore. When conditions are favourable an infant moves away from mother on explorat- ory excursions and returns to her again from time to time. By eight months of age almost every in- fant observed who had had a stable mother-figure to whom to become attached showed this beha- viour; but, should mother be absent, such organ- ized excursions became much less evident or ceased. As a result of these and similar findings, both for human and for monkey infants, the
109/362
? ? ? notion has been developed that an ordinary de- voted mother provides a child with a secure base from which he can explore and to which he can return when upset or frightened. Similar observa- tions, of course, have been made by Margaret Mahler (Mahler, Pine, and Bergman, 1975), though she interprets them in terms of a theoret- ical framework different to the one which Ainsworth and I use. This concept of the secure personal base, from which a child, an adolescent, or an adult goes out to explore and to which he returns from time to time, is one I have come to regard as crucial for an understanding of how an emotionally stable person develops and functions all through his life.
In her project in Baltimore, Ainsworth was not only able to study this kind of behaviour more closely but described many individual variations of it to be seen in a sample of 23 infants at 12 months of age. Observations were made of the in- fants' exploratory and attachment behaviour, and the balance between them, both when the infants were at home with mother and also when they were placed in a slightly strange test situation. In addition, having obtained data on the type of mothering each infant had been receiving
110/362
? ? ? throughout his first year of life (by means of pro- longed observation sessions at three weekly inter- vals in the child's home), Ainsworth was in a pos- ition to propose hypotheses linking certain types of emotional and behavioural development at 12 months with certain types of preceding mother- ing experience.
The findings of the study (see the review by Ainsworth, 1977) show that the way a particular infant of 12 months behaves with and without his mother at home and the way he behaves with and without her in a slightly strange test situation have much in common. Drawing on observations of behaviour in both types of situation it is then possible to classify the infants into three main groups, according to two criteria: (a) how much or how little they explore when with mother or without her, and (b) how they treat moth- er--when she is present, when she departs, and, especially, when she returns.
There were eight children whose overall beha- viour at their first birthday Ainsworth was dis- posed to regard as promising well for the future. Such infants explored actively, especially in mother's presence, and used mother as a base by keeping note of her whereabouts, exchanging
