Development of perceptual completion originates in information acquisition

Adults have little difficulty perceiving objects as complete despite occlusion, but newborn infants perceive moving partly occluded objects solely in terms of visible surfaces. The developmental mechanisms leading to perceptual completion have never been adequately explained. Here, the authors examine the potential contributions of oculomotor behavior and motion sensitivity to perceptual completion performance in individual infants. Young infants were presented with a center-occluded rod, moving back and forth against a textured background, to assess perceptual completion. Infants also participated in tasks to assess oculomotor scanning patterns and motion direction discrimination. Individual differences in perceptual completion performance were strongly correlated with scanning patterns but were unrelated to motion direction discrimination. The authors present a new model of development of perceptual completion that posits a critical role for targeted visual scanning, an early developing oculomotor action system.

Therapeutic interventions in infancy: Two contrasting cases of persistent crying

Infants are liable to many symptoms of emotional disturbance. However, it is now widely agreed that there is no such thing as individual psychopathology in infancy. Infantile disturbances are considered to be a function of current relationships. The paper briefly summarises available psychodynamic approaches to problems in infant relationships. It argues that more case-studies of therapeutic interventions in infancy are needed to increase our understanding of early disturbances and of their treatment. Two contrasting case-studies of intervention in persistent crying attempt to understand what may sustain this distressing problem. In each case the possible meaning of the crying, both to the babies and to their families, is considered.     

Facing fascism: A feminine politics of jouissance

Conclusion To resume, then, the need for a written Law specifically prohibiting Genocide. (1) It should by now be evident that the pleasure principle needs its ethical mandate, beyond the reality principle of a social field that can no longer be considered homeostatic and nonconflictual. The fantasmatic character of human pleasure must not only be accounted for in any ethic today, it must take primacy. Fantasy formations grow ever central in our lives; fantasy is the support of our reality.(2) The writing of such a Law would permit the enunciation of positively negative content, thereby reframing the Other as lacking; and it would also provide a way for the increasingly stateless citizens of the postmodern, global community, to be asked todecide on the necessarily paired alternatives (Good and Evil, to kill or to love) which have once again become the starkest of possibilities for them. Only this kind of decision — which is not that of thevel — suffers resistance to the will of the people when it is a malignant will-to-jouissance.     

EFFECTS OF REINFORCEMENT FOR ALTERNATIVE BEHAVIOR DURING PUNISHMENT OF SELF-INJURY

A number of variables influence the effectiveness of punishment and may determine the extent to which less intrusive forms of punishment may be used as alternatives to more intrusive interventions. For example, it has been suggested that response suppression during punishment may be facilitated if reinforcement is concurrently available for an alternative response. However, results of basic research demonstrating this finding have not been replicated with interventions more commonly prescribed as treatments for problem behavior. We evaluated the effects of relatively benign punishment procedures (reprimands or brief manual restraint) on the self-injurious behavior of 4 individuals who had been diagnosed with mental retardation, when access to reinforcement for alternative behavior (manipulation of leisure materials) was and was not available. In all cases, punishment produced greater response suppression when reinforcement for an alternative response was available.     

A Practical Guide to the Comparative Case Study Method in Political Psychology

The case study, as a method of inquiry, is particularly suited to the field of political psychology. Yet there is little training in political science, and even less in psychology, on how to do case study research. Furthermore, misconceptions about case studies contribute to the methodological barrier that exists within and between the two parent disciplines. This paper reviews the various definitions and uses of case studies and integrates a number of recent insights and advances into a practical guide for conducting case study research. To this end, the paper discusses various stereotypes of the case study and offers specific steps aimed at addressing these criticisms.     

Loss of control over eating reflects eating disturbances and general psychopathology

This study examined the clinical significance of the loss of control over eating as a key component of eating disorders. It investigated the association of eating-related psychopathology and general psychopathology with objective bulimic episodes (OBEs; experiencing a loss of control while consuming large amounts of food) and subjective bulimic episodes (SBEs; experiencing a loss of control while consuming small/moderate amounts). A community sample of 81 women with a range of disordered eating was recruited: binge-eating disorder, bulimia nervosa, subclinical eating disturbances, or no eating disorders. They were interviewed using the Eating Disorder Examination and completed measures of eating-related and general psychopathology. Both OBE and SBE frequencies correlated significantly with measures of eating-related and general psychopathology, and no significant differences were found between the magnitudes of the correlations with either binge episode type. SBE frequency significantly and independently predicted global eating disorder psychopathology. The loss of control over eating, without consuming large amounts of food, was as closely associated with specific eating disorder psychopathology and general mental health as were traditionally defined OBEs. SBEs may be an important target of treatment and should be considered for future diagnostic classifications of eating disorders.     

On Associative Stigma: Implicit and Explicit Evaluations of a Mother of a Child with Autism Spectrum Disorder

Individuals with psychiatric problems are subjected to highly damaging stigma. Some research suggests that this stigma may extend to associates (e.g., family, friends), who themselves report being devalued, avoided, and rejected. The research literature on associative stigma is largely qualitative, and extant quantitative research has utilized only explicit measures which are notably weakened by self-presentational motives. In the current study, 95 undergraduates were randomized to hear one of two audio recorded vignettes pertaining to a fictional mother of a child with either autism spectrum disorder (ASD) or severe asthma. Participants then completed an Implicit Association Test capturing implicit evaluations of the fictional mother and two separate measures of explicit stigma. No group differences for either explicit measure emerged. However, the predicted group difference in implicit stigma emerged, such that the mother of the child with ASD was evaluated less positively than the mother of the child with severe asthma. Implicit-explicit correlations were not statistically significant but in the small to medium range according to effect size conventions. This study offers evidence of implicit associative stigma in the psychiatric domain. It also points to a variety of interesting avenues for further illumination of this potentially important phenomenon.
