Two forms of persistence in visual information processing

Iconic memory, which was initially regarded as a unitary phenomenon, has since been subdivided into several components. In the present work we examined the joint effects of two such components (visible persistence and the visual analog representation) on performance in a partial report task. The display consisted of 15 alphabetic characters arranged around the perimeter of an imaginary circle on the face of an oscilloscope. The observer named the character singled out by a bar-probe. Two factors were varied: exposure duration of the array (10, 50, 100, 150, 200, 300, 400 or 500 ms) and duration of blank period (interstimulus interval, ISI) between the termination of the array and the onset of the probe (0, 50, 100, 150, or 200 ms). Performance was progressively impaired as both exposure duration and ISI were increased. The results were explained in terms of a probabilistic combinatorial model in which the timecourses of visible persistence and of the visual analog representation are regarded as time-locked to the onset and to the end of stimulation, respectively. The impairing effect of exposure duration was attributed to the relatively high spatial demands of the task that could be met optimally by information in visible persistence (which declines as a function of exposure duration), but less adequately by information in the visual analog representation. A second experiment, employing a task with lesser spatial demands, confirmed this interpretation.     

Some Ethical Issues In Applied Social Psychology: The Case of Bilingual Education and Self-esteem

Ideas and theories from social psychology are often put to practical use. Sometimes these borrowed concepts and theories are carefully implemented, sometimes they are not. Education is a practical area where social psychology is often applied, sometimes without much care. As an example of the problem, this article examines how educators used self-esteem to justify bilingual education programs for language minority students and whether this application of social psychology is warranted. We find that the postulated effect of bilingual educations on self-esteem does not occur. Also, self-esteem research and theory are misapplied in attempting to justify bilingual education with respect to its supposed effects on self-esteem. Finally, we raise the question of what responsibility the field of social psychology has to correct misapplication of theory and concepts.     

FADING TEACHER PROMPTS PROM PEER-INITIATION INTERVENTIONS FOR YOUNG CHILDREN WITH DISABILITIES

This study examined a system for fading teacher prompts to children who served as peers in peer-initiation interventions for young children with disabilities. A teacher taught peers to direct social initiations to children with disabilities, provided verbal prompts for those initiations, and introduced a system that provided peers with visual feedback about the social interactions of the children with disabilities. She then systematically withdrew the verbal prompts to peers, and subsequently faded the visual feedback system. Peer initiations increased when the intervention began and resulted in increases in social interaction for the children with disabilities. As the teacher systematically faded the prompts and visual feedback to the peers, social interaction continued at the levels found during intervention and was maintained during a short maintenance period.     

The use and opposition of rape myths in prime-time television dramas

The act of rape violates two deeply held values of American culture: the right to justice and the right of physical integrity. Despite this fact, thousands of women are raped each year. The victim of rape often becomes the target of blame; in one aspect or another she is held accountable for her victimization. Through the use of rape myths, which are grounded in patriarchal expectations of gender role behavior, our culture unites the apparently dichotomous opposites of the rights to justice and physical integrity. While rape myths have received extensive attention from behaviorists, their communication through the mass media has been ignored. This study focuses on the use of, and opposition to, rape myths in prime-time television dramas, as well as discusses the implications of those depictions.This study was derived from my doctoral dissertation, which was directed by Dr. Pamela Benoit, University of Missouri — Columbia.     

An exploratory study of videotapes of long-term group psychotherapy of outpatients with major and chronic mental illness

This study explored patterns emerging in videotaped sessions of group psychotherapy with seven outpatients of a large mental health facility. The 22 sessions spanned the 12th to 27th months of the group's existence. Group members had long histories (25–50 years) of symptoms characteristic of schizophrenia. Each session was rated on the Group Environment Scale. One session from a group in its earlier stages was also rated on the same instrument to give some indication of baseline patterns. Analyses of changes across the 15 months were not statistically significant. However, some GES subscales, including Cohesion, Independence, and Self-Discovery, showed relatively high mean levels across the 15-month period. These elevations are discussed as suggesting the codevelopment of orientations that have sometimes been viewed as incompatible and unattainable for schizophrenics. Interpreted clinically, the GES patterns help to elaborate recent findings about the relatively good success of long-term group therapy with such populations. The study, although merely suggestive, illustrates the potential for gleaning solid and clinically useful data from group psychotherapy research.The authors would like to thank Drs. Jill Rierdan, Nina Fieldsteel, Joseph Christy, and an anonymous reviewer for their suggestions, Kendra Bryant for serving as the reliability rater, and Janet Eltinge for her skilled videotaping.     

The Logic of the Development of Feminism; or,Is MacKinnon to Feminism as Parmenides Is to Greek Philosophy?

Catharine MacKinnon's investigation of the role of sexuality in the subordination of women is a logical culmination of radical feminist thought. If this is correct, the position of her work relative to radical feminism is analogous to the place Parmenides's work occupied in ancient Greek philosophy. Critics of MacKinnon's work have missed their target completely and must engage her work in a different way if feminist theory is to progress past its current stalemated malaise.     

Parent attributions of emotion to their children and the cues children use in perceiving their own emotions

A number of studies have demonstrated stable individual differences in the cues that generate emotions and other feeling states. These differences are assumed to arise from the cues parents use to identify their children's emotional states. As children learn about their own emotional states, they come to rely on these same cues. To test one implication of their view, the facial expressions of children (N=41) were manipulated and their feelings assessed. Some children reported emotions consistent with their expressions, while others reported emotions appropriate to the situation. In a separate procedure, their mothers were asked to identify the emotional states of children whose expressions were inconsistent with an account of their circumstances. Mothers who paid more attention to their children's expressive behavior had children who were more responsive to their own expressive behavior. In contrast, the mothers who were more responsive to situational cues had children whose emotions arose from the situational cues as well.The authors would like to thank numerous teachers and administrators of the Worcester Public School system in Worcester, Massachusetts, for their assistance.
