Gender Differences in PTSD diagnostic Criteria and Suicidal Ideation in a South African Police Sample

The study examined gender effects on PTSD symptoms to predict of suicidal ideation in a sample of South African police. A male (N = 161) and a female group (N = 56) of South African police officers were assessed by means of the Posttraumatic Diagnostic Scale and a short version of the Adult Suicide Ideation Questionnaire. Linear and stepwise regressions were used to determine which PTSD symptom criteria best predict suicide ideation. Hyperarousal was the primary predictor of suicide ideation in males. For females, intrusive memories was the primary predictor of suicide ideation, and of general problems.     

Anxiety and Adjustment Levels Among the Visually and Hearing Impaired and Their Relationship to Locus of Control,Cognitive, Social,and Biographical Variables

Forty-five hearing-impaired and 40 visually impaired male residential school children aged 6 to 16 years were administered measures of adjustment, anxiety, and locus of control (LOC). Scores related to intelligence and academic level, teacher and peer acceptance, and biographical variables were also obtained. The findings show that the correlates of anxiety and adjustment differed qualitatively as well as quantitatively between the groups.     

Intellectual Profiles and Violent Behavior in Juvenile Delinquents

Hemispheric laterality, measured by the Wechsler Verbal IQ-Performance IQ differential score, in a large group of delinquents (N = 101) was not associated with violent-nonviolent behavior. Delinquents were, however, likely to be relatively more impaired on verbal than on nonverbal intellectual capacities.     

The Effect of Attachment Insecurity in the Development of Eating Disturbances across Gender: The Role of Body Dissatisfaction

The present study examined the effects of insecure attachment on the development of negative body image as a contributing factor to the development of disturbed-eating patterns in male and female university students. Participants were nonclinical male (n = 100) and female (n = 381) university students. Administering self-report questionnaires, the authors assessed demographic information (gender, age), anthropometric data (Body Mass Index [BMI], age), romantic attachment (ECRS-R; R. C. Fraley, N. G. Waller, & K. A. Brennan, 2000), body dissatisfaction (BSQ), and disturbed eating (EAT-26). The authors found body dissatisfaction to fully mediate the relationship between attachment anxiety and disordered eating in women. Body dissatisfaction mediated anxious attachment and dieting in men. In addition, attachment avoidance had a direct impact on eating behaviors for both genders, without the mediation of any variables measured in this study. The findings of the present study suggest that the anxiety and avoidance dimensions of attachment insecurity affect eating behaviors differently, and the effects are different across genders. The authors discuss results in the context of therapeutic interventions design.     

Loneliness: Lost in the Landscape of Meaning

The present study is an examination of sex differences in the sources of annoyance that partners in close relationships might experience as a result of each other's behavior. To test hypotheses derived from S. E. Cross and L. Madson's (1997) self-construal theory and from D. M. Buss's (1989) evolutionary psychology-based model, men and women of varying ages and educational levels were asked to rate how annoyed they would be with each of 13 potentially annoying behaviors of their intimate partner. Results were consistent with self-construal theory in that relationship-threatening behaviors were more annoying to women than to men and autonomy threatening behaviors were more annoying to men than to women. Results were also consistent with evolutionary psychology in that aggressive behaviors were more annoying to women than to men and sexual withholding was relatively more annoying to men than to women. Sex differences in annoyance with relationship-threatening, autonomy-threatening, and reproductive strategy behaviors were independent of age and education level, although these factors did affect respondents' annoyance when partners were unemotional, sloppy, or pleased with their own appearance. Results showed that sources of annoyance in intimate relationships should not only be studied from an evolutionary perspective but from the perspectives of social, personality, and developmental psychology as well.     

Selective Attention in Animal Discrimination Learning

The traditional approach to the study of selective attention in animal discrimination learning has been to ask if animals are capable of the central selective processing of stimuli, such that certain aspects of the discriminative stimuli are partially or wholly ignored while their relationships to each other, or other relevant stimuli, are processed. A notable characteristic of this research has been that procedures involve the acquisition of discriminations, and the issue of concern is whether learning is selectively determined by the stimulus dimension defined by the discriminative stimuli. Although there is support for this kind of selective attention, in many cases, simpler nonattentional accounts are sufficient to explain the results. An alternative approach involves procedures more similar to those used in human information-processing research. When selective attention is studied in humans, it generally involves the steady state performance of tasks for which there is limited time allowed for stimulus input and a relatively large amount of relevant information to be processed; thus, attention must be selective or divided. When this approach is applied to animals and alternative accounts have been ruled out, stronger evidence for selective or divided attention in animals has been found. Similar processes are thought to be involved when animals search more natural environments for targets. Finally, an attempt is made to distinguish these top-down attentional processes from more automatic preattentional processes that have been studied in humans and other animals.     

Examining Conspiracist Beliefs About the Disappearance of Amelia Earhart

Previous studies have suggested that conspiracist ideation forms part of a monological belief system in which one conspiracist idea acts as evidence for new conspiracist ideas. Here, we examined this possibility in relation to an event lacking reliable or conclusive evidence, namely the disappearance of Amelia Earhart and Fred Noonan. A total of 914 members of the British general public completed scales measuring their beliefs about the disappearance of Earhart and Noonan, belief in conspiracy theories, the Big Five personality factors, support for democratic principles, political cynicism, self-esteem, and self-assessed intelligence. Results showed that belief in conspiracy theories was associated with the endorsement of less plausible explanations for the disappearance of Earhart and Noonan. In addition, belief in less plausible explanations was also significantly associated with lower self-assessed intelligence, greater political cynicism, lower self-esteem, and higher Agreeableness scores. These results are discussed in relation to monological belief systems.     

Perceptions of Younger Single Adults as a Function of Their Gender and Number of Children

ABSTRACT. Research suggests that children may interfere with single parents’ romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed.
