Stress,Coping and Adjustment in Victims of Sexual Assault: The role of psychological defense mechanisms

The paper considers sexual abuse within a stress and coping framework with particular emphasis on victim-initiated psychological defense mechanisms in the recovery process. Analysis of case history data from 40 adolescent victims of sexual abuse indicated that 90% used psychological defense mechanisms, particularly repression, emotional insulation and rationalisation. The paper explores the usefulness of such mechanisms from a theoretical and applied perspective and compares these Singaporean findings with earlier research conducted in the United States.     

Neuroanatomical correlates of handedness for tool use in chimpanzees (Pan troglodytes): implication for theories on the evolution of language

It has been hypothesized that cognitive mechanisms underlying lateralized complex motor actions associated with tool use in chimpanzees may have set the stage for the evolution of left-hemisphere specialization for language and speech in humans. Here we report evidence that asymmetries in the homologues to Broca's and Wernicke's areas are associated with handedness for tool use in chimpanzees. These results suggest that the neural substrates of tool use may have served as a preadaptation for the evolution of language and speech in modern humans.     

A latent class analysis of positive psychosis symptoms based on the British Psychiatric Morbidity Survey

This study aimed to describe the distribution of positive psychosis symptoms in a large scale, population-based sample. Data from the British Psychiatric Morbidity Survey was used to examine homogeneous sub-types of participants based on their responses to the five probe items of the Psychosis Screening Questionnaire. Latent class analysis was used to identify the underlying class structure of psychosis. Four classes of psychosis were identified. Associations between the latent classes and the demographic risk factors, clinical variables and reports of traumatic experiences showed significantly higher risks for the psychosis class, the paranoid class, and the intermediate class compared to the normative class. Four classes that appeared to represent an underlying continuum could best explain psychosis symptom expression at the population level.     

Deterrence, Opportunity, and Choice

Traditional studies of deterrence have focused on punishment with less regard for the rewards of both crime and noncrime. Influenced by work in economics and behavioral psychology, more recent studies have departed from tradition by incorporating rewards for crime. To this extent, they should be regarded as advances over the more traditional approaches. Notwithstanding these advances, variations in both the probability and magnitude of reward for noncrime have not been systematically included in these more recent theories of choice. In an attempt to determine whether opportunities for noncrime are either central or trivial to the criminal decision-making process, the present study fitted two alternative models to experimental data involving risk-taking: (a) the economic utility model employed by Piliavin, Gartner, Thornton, and Matsueda (1986) in their study of criminal choice; and (b) the satisfaction balance model developed by Gray and Tallman (1984). Results showed that while both models explained significant amounts of variation in the dependent variable, the Gray-Tallman model provided a substantially better fit of the data. Despite limitations inherent in experimental studies as, for example, limitations surrounding the issue of external validity, the findings strongly suggest that opportunities for noncrime are as important as rewards and costs for crime in the process by which criminal decisions are made.     

The Relationship Between Attitudes Toward Persons Who Are Gay and Persons With AIDS,and HIV and AIDS Knowledge

A total of 86 counseling students were assessed on their attitudes toward persons who are gay, attitudes toward persons with AIDS (Acquired Immune Deficiency Syndrome), and level of HIV (human immunodeficiency virus) and AIDS knowledge. Demographic data consisted of sex, age, and HIV- and AIDS-related training. Results indicated that the attitudinal and knowledge variables were correlated so that positive attitudes toward both groups corresponded with high levels of knowledge. There were no significant differences among these variables on the demographic factors. Implications of these results are discussed, with special emphasis placed on counselor education.     

Assisting At-Risk College Students With Attributional Retraining and Effective Teaching1

Attributional retraining appears to be an effective remedial intervention for college students. However, the potential moderating effects of student and classroom characteristics have not yet been investigated systematically. In two studies, attributional retraining was provided to low- and high-risk students, followed by a videotaped lecture presented by either an ineffective or effective instructor. Attributional retraining enhanced achievement on a lecture-based achievement test only when combined with effective teaching, improving the achievement of students who had previously performed poorly (Experiment l), and of low-achieving externals (Experiment 2). The intervention provided no advantage for previously successful students and low-achieving internals. Moreover, attributional retraining induced a more internal attribution profile in students with an external locus, and increased expectations of future success in both externals and internals, but again only when students also received effective instruction. These results suggest that contextual factors related to the classroom, such as quality of instruction, and individual differences have to be considered when developing attributional retraining programs.     

Reducing faking on personality tests: Testing a new faking‐mitigation procedure in a U.S. job applicant sample

Faking has remained a major concern for organizations using self‐report personality measures for selection. Scholars recenlty developed a new middle‐warning faking‐mitigation procedure. The present replication study was the first field test in the United States using 193 applicants for an entry‐level position in a New York‐based consulting firm. Results replicated most of Fan et al.'s findings including (a) the middle‐warning significantly lowered fakers' personality scores over retesting, whereas the control message had little influence on nonfakers; (b) the above warning effect carried over to personality scales that were not retested; and (c) the persistent tendency of potential fakers rising to the top of personality score distribution was weakened. In addition, applicants' perceptions were not being negatively affected by the warning.     

The role of social support in fostering school engagement in urban schools characterised by high risk of early leaving from education and training

Tackling early leaving from education and training (ELET) is one of the main education policy targets of the European Union and many of its member states. This paper offers new insights on this issue by studying how so-called at-risk students develop their educational trajectory by embedding their attitudes towards and engagement in schooling within the various support networks they navigate. We argue that the concept of school engagement, operationalized within the broader theoretical framework of the self-system model of motivational development, is crucial for better understanding ELET. The structural equation modelling is based upon survey data from 1401 students in grade 10 and 12 of vocational tracks across 26 different urban school locations in Flanders, Belgium. The results show that parental, peer and in particular teacher support directly and indirectly strengthen students’ academic and behavioural engagement. We argue that universal and targeted support by educators can positively impact pro-school attitudes and school engagement of so-called at-risk students and may be one of the most important strategies in addressing ELET.

     

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.
