An X Windows tool for synthesizing face images from eigenvectors

An X Windows software tool for the construction of faces with a weighted combination of eigenvectors is described. The eigenvectors were extracted from an autoassociative matrix that comprised 100 face images. The program input consists of eigenvectors and sets of weights that describe individual faces and combines these to create face images. The tool creates a panel of buttons that permits the display of individual eigenvectors and the display of an average face as well. Facilities for on-line changes to the intensity of individual eigenvectors can be used to change the appearance of a face. Previously, O’Toole, Abdi, Deffenbacher, and Bartlett (1991) have shown that the intensity of certain individual eigenvectors contains reliable information for determining the sex and race of the face.     

Practices and representations of child care and motor development among West Africans in Paris

Massage techniques and postural manipulation used by West African women immigrants in Paris were studied, with the aim of demonstrating that culturally regulated caretaking practices have an influence on infant motor development. Twenty-five infants were observed between the ages of 3 and 12 months and 9 and 15 months. Frequency of massage and its accompanying set of physical exercises were found to be related to age at onset of independent walking. The findings show that infants receiving daily massage walk significantly earlier than infants who do not receive massage, thus confirming other reports that vestibular and postural stimulation have a positive effect on motor development. These results are discussed in relation to the observed frequencey of contact and of physical games with the caregiver for a smaller sample of three infants, and to parental expectations about the age of acquisition of certain cognitive and motor abilities. African immigrant mothers expect their infants to sit and to walk earlier than French mothers. The conclusion emphasizes the contribution of social anthropology, which shows that in all cultures, physical development and body changes elicit symbolic practices and a search for explanation.     

Perceived motion in structure from motion: Pointing responses to the axis of rotation

We investigated the ability to match finger orientation to the direction of the axis of rotation in structure-from-motion displays. Preliminary experiments verified that subjects could accurately use the index finger to report direction. The remainder of the experiments studied the perception of the axis of rotation from full rotations of a group of discrete points, the profiles of a rotating ellipsoid, and two views of a group of discrete points. Subjects’ responses were analyzed by decomposing the pointing responses into their slant and tilt components. Overall, the results indicated that subjects were sensitive to both slant and tilt. However, when the axis of rotation was near the viewing direction, subjects had difficulty reporting tilt with profiles and two views and showed a large bias in their slant judgments with two views and full rotations. These results are not entirely consistent with theoretical predictions. The results, particularly for two views, suggest that additional constraints are used by humans in the recovery of structure from motion.     

Women and men in conversation: a consideration of therapists' interruptions in therapeutic discourse

Studies of day-to-day conversation have shown that interrupting can be used as a gendered means of determining both conversational topic and speaker. This paper explores the nature of interruptions in therapeutic conversations in this light. Drawing upon two recent studies of therapists' interruptions, the author offers some preliminary ideas for consideration by therapists, clinical supervisors and researchers.     

Writers Blocked: On the Wrongs of Research Co-authorship and Some Possible Strategies for Improvement

The various problems associated with co-authorship of research articles have attracted much attention in recent years. We believe that this (hopefully) growing awareness is a very welcome development. However, we will argue that the particular and increasing importance of authorship and the harmful implications of current practices of research authorship for junior researchers have not been emphasised enough. We will use the case of our own research area (bioethics) to illustrate some of the pitfalls of current publishing practices—in particular, the impact on the evaluation of one’s work in the area of employment or funding. Even where there are explicit guidelines, they are often disregarded. This disregard, which is often exemplified through the inflation of co-authorship in some research areas, may seem benign to some of us; but it is not. Attribution of co-authorship for reasons other than merit in relation to the publication misrepresents the work towards that publication, and generates unfair competition. We make a case for increasing awareness, for transparency and for more explicit guidelines and regulation of research co-authorship within and across research areas. We examine some of the most sensitive areas of concern and their implications for researchers, particularly junior ones, and we suggest several strategies for future action.     

Could Presentism in the Histories of Psychology Actually be Futuristic?

Disputes about the origins of psychology in the history of the discipline are functional not for our understanding of the past, but as normative signs that regulate the construction of ideas in the future. We introduce the notion of open-ended normativity that regulates the development of a given discipline towards its future. Hence the question of the cultural origins of psychology becomes contested in the 21st century as an important topic. It proves that the history of psychology is an active participant in the making of psychology, as it is creating its future.     

Implicit Theories of Common Health Conditions Held by Indian Social Workers and Students

Social work is viewed as a change-related profession. However, little is known about social workers’ own beliefs about change. To understand this, we used the implicit theory paradigm to compare theories about various health conditions held by social workers, social work students, and undergraduate students from Bombay, India (N = 352). The participants had to assess the possibility of change in four health conditions: cancer, tuberculosis, depression, and mental retardation. We predicted that social workers whose professional education involves concepts such as Person-in-Environment would display more incremental views of these conditions than students – namely that they are modifiable. Our predictions were supported for the following conditions: cancer, tuberculosis, and depression. These incremental views were neither related to age nor years of professional experience. Though we expected that the extent to which participants believed these health issues to be amenable to change would influence their support for a small personal tax, our findings did not bear this out. We explore the possible reasons for our findings and discuss their implications for health communication in India as well as for social work education.     

GREAT IDEAS AND DUMB LUCK IN PSYCHOANALYTIC PSYCHOTHERAPY

Both Dr. Kuriloff’s initial contribution to the Roundtable, and her later response to her fellow discussants focus on the social construction of psychoanalytic theories of therapeutic action. She notes the promise of the enlightenment/ modern era as impetus for an initially positivist “science” of psychoanalysis, and then implicates the scourge of the Shoah as that which galvanized the largely Jewish seminal community to cling to universal, versus contextual theories and technique. That the deconstruction of truth and authority, beginning with the post-war “baby boom” and student movements in the United States and Europe, put an end to one metapsychology is yet another example of the power of context upon ideas and praxis. This seemingly haphazard pairing of context and content determines the degree to which theories are embraced or ignored within any particular body politic, or within our tiny community at one time or another, prompting Kuriloff to warn against over valuing and/or excluding any theory, theorist, or technique from what we need to know and do to be helpful to people. This tension—between immersion in, and observation of the field—is what psychoanalytic theory and praxis ought to allow.     

WHAT IS EFFECTIVE IN PSYCHOANALYTIC PSYCHOTHERAPY? SOME THINGS CHANGE,SOME STAY THE SAME

As a reflection on two roundtable discussions published in the American Journal of Psychoanalysis in 1957 and 1965, the author seeks to provide historical context for what has taken place within the culture, within the profession, and within himself over this period of time. The struggle to define “effectiveness” is addressed and an argument made for the inclusion of empirical research into our work, but with simultaneous appreciation for the difficulty in objectively defining and measuring what takes place within the therapeutic relationship. This difficulty is hypothesized, in part, to be a function of the non-verbal and preverbal experiences of both patient and therapist.
