Object recognition contributions to figure-ground organization: Operations on outlines and subjective contours

In previous research, replicated here, we found that some object recognition processes influence figure-ground organization. We have proposed that these object recognition processes operate on edges (or contours)detected early in visual processing, rather than on regions. Consistent with this proposal, influences from object recognition on figure-ground organization were previously observed in both pictures and stereograms depicting regions of different luminance, but not in randomdot stereograms, where edges arise late in processing (Peterson & Gibson, 1993). In the present experiments, we examined whether or not two other types of contours—outlines and subjective contours—enable object recognition influences on figure-ground organization. For both types of contours we observed a pattern of effects similar to that originally obtained with luminance edges. The results of these experiments are valuable for distinguishing between alternative views of the mechanisms mediating object recognition influences on figure-ground organization. In addition, in both Experiments 1 and 2, fixated regions were seen as figure longer than nonfixated regions, suggesting that fixation location must be included among the variables relevant to figure-ground organization.     

Effects of anxiety sensitivity on emotional response to a stress task

The purpose of this investigation was to further define the role of anxiety sensitivity, in relation to physiological arousal and the cognitive perception of anxiousness, as a determinant of anxiety. One hundred and thirty-two undergraduates at an urban university served as subjects. Two physiological measures of arousal and two cognitive measures of anxiety were used following an anxiety inducing task (mental arithmetic). The general expectation, which was supported, was that individual differences in anxiety sensitivity levels are more closely related to subjects' reported anxiousness in stressful conditions than are the actual physiological changes. Additionally, anxiety sensitivity was related to poststress levels of anxiety whereas trait anxiety was only related to pre- and postrelaxation levels of anxiety. Implications of the findings are addressed.     

Anger of women incest survivors

Adult women survivors of incest (n = 68) were compared to other women (n = 93) with respect to several questionnaire measures of manifest anger. The vast majority of the research participants were white, middle class, heterosexual, and Michigan residents. Incest survivors were angrier than other women, both in general and at their parents. Anger toward mother and anger toward father were comparable. Few incest survivors blamed either parent for the incest, except in those speciflc cases where the parent was a perpetrator. Not surprisingly, incest survivors were particularly angry at parent perpetrators when they were held responsible for the abuse. Incest occurred in families where other traumas were present, and the extent of these other traumas was also associated with increased anger at parents. Women who identified with feminism and who had participated in therapy were angrier at their parents than were other women. Therapy implications of these results were discussed.This paper is based on a doctoral dissertation submitted to the University of Michigan by the first author, under the supervision of the second author.

Personal advertisements of male-to-female transsexuals,homosexual men,and heterosexuals

Transsexuals, because of their attempts at gender reversal, offer a unique opportunity to study self-presentation, social roles, and stereotypes. The present study is a content analysis of personal advertisements of male-to-female transsexuals (TM, N =99), homosexual (HoM, N =64) and heterosexual men (HM, N =99), and heterosexual women (HW, N =99). Advertisements were coded for the presence or absence of 11 characteristics either offered or sought, based on the 1984 work of Deaux and Hanna. The content of TM personal advertisements was significantly different from those of HW, HM, or HoM. TM mentioned physical characteristics and sincerity, and requested friendship most often; HoM mentioned sexuality most often; HM offered financial security and status in the form of occupation, and listed marital status most often; and HW offered personality characteristics and attractiveness most often. Several factors may contribute to the pattern of differences observed, including the fact that TM were more likely to be seeking friendship than sexual partners, in contrast to the other three groups.     

Gifted Achievers and Underachievers: A Comparison of Patterns Found in School Files

Underachievement in gifted students has perplexed educators and parents for decades. Researchers are continually looking for information about the nature and patterns of gifted underachievers that will enlighten those concerned. Counselors are particularly involved, because they often are asked to provide illumination and interventions. This study demonstrates how information in the cumulative school file, accessible to the school counselor, is a rich resource for understanding the patterns of achievement and underachievement among students identified as gifted and for use in planning interventions for students at risk for underachievement. Participants were gifted students (N = 153) who were determined to be either achievers or under-achievers, based on their grade point average at graduation. High and moderate achievers and moderate and extreme underachievers were compared on information found in the school file, such as attendance, tardiness, course selection, and onset and duration of underachievement. Results indicate that there are differences between achievers and underachievers on a number of variables found in the school files. Profiles of these groups are presented with suggestions for actions by counselors.     

Counseling and screening for cystic fibrosis in patients with congenital bilateral absence of the vas deferens: Patient perceptions

Congenital bilateral absence of the vas deferens (CBAVD) occurs in approximately 1.3% of infertile males and is thought to be, in most cases, a primarily genital form of cystic fibrosis (CF). Fourteen males with CBAVD considering microsurgical sperm aspiration from the epididymis (MESA) and in vitro fertilization were seen for genetic counseling and screening for CF. To retrospectively evaluate these patients' perceptions of the counseling and screening information, we conducted structured telephone interviews to assess their recall of information about CF and its impact on their health concerns and reproductive plans. We found that, as the health implications of CF are abstract and not as important to patients as the diagnosis of CBAVD itself, patients tend to view their CF status primarily in terms of their reproductive potential. Retrospective analysis afforded us an opportunity to identify the psychosocial issues of most concern to this unique patient population.     

The psychologist's role in assessing and facilitating patients' knowledge of advance directives in medical settings: A preliminary investigation

In a time of budgetary shortfalls in the medical industry, an aging population, and an increased emphasis on health care choices, psychologists are being called upon to administer advance medical directive programs to patients. This study reports preliminary findings from a program to assess and facilitate patients' knowledge of advance directives (ADs) by the Psychology Service at the Ann Arbor VA Medical Center. The participant pool included 243 male veteran patients admitted to medical and surgical wards at the hospital. The intervention included the use of a computer-generated prompt for consultation, which was sent to the psychology staff in response to a patient inquiry regarding ADs. It also involved an increased emphasis on the delivery of written material on ADs by the admissions clerks. The intervention appeared to result in a modest increase in patients' knowledge of advance directives. Suggestions are offered for areas that should be emphasized in future attempts to increase patients' knowledge and utilization of advance directives.     

Nonstranger sexual aggression: A discriminant analysis of the psychological characteristics of undetected offenders

Sex Roles - Rape is an underreported and underconvicted crime. Therefore, many highly sexually aggressive men are missed by research employing judicial identification for sample selection. The...
