Hope as a Predictor of Interpersonal Suicide Risk

The current study hypothesized that (1) hope would negatively predict burdensomeness, thwarted belongingness, and acquired capability to enact lethal injury; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results indicated that hope negatively predicted burdensomeness and thwarted belongingness, but positively predicted acquired capability to enact suicide. Contrary to our second hypothesis, hope did not predict suicidal ideation, but interpersonal risk factors for suicide predicted suicidal ideation. Results are discussed in terms of implications for hope theory and Joiner's (2005) interpersonal risk factors for suicide, and for clinical practice.     

Links between physical fitness and cardiovascular reactivity and recovery to psychological stressors: A meta-analysis.

A meta-analysis of published studies with adult human participants was conducted to evaluate whether physical fitness attenuates cardiovascular reactivity and improves recovery from acute psychological stressors. Thirty-three studies met selection criteria; 18 were included in recovery analyses. Effect sizes and moderator influences were calculated by using meta-analysis software. A fixed effects model was fit initially; however, between-studies heterogeneity could not be explained even after inclusion of moderators. Therefore, to account for residual heterogeneity, a random effects model was estimated. Under this model, fit individuals showed significantly attenuated heart rate and systolic blood pressure reactivity and a trend toward attenuated diastolic blood pressure reactivity. Fit individuals also showed faster heart rate recovery, but there were no significant differences in systolic blood pressure or diastolic blood pressure recovery. No significant moderators emerged. Results have important implications for elucidating mechanisms underlying effects of fitness on cardiovascular disease and suggest that fitness may be an important confound in studies of stress reactivity.     

Context specificity of latent inhibition in taste aversion learning

In three experiments rats were given injections of LiCl after consuming distinctively flavoured water. The rats developed an aversion to the flavour and in all experiments the magnitude of the aversion was found to be reduced in subjects that had received pre-exposure to the flavour without aversive consequences. Experiment 1 demonstrated this pre-exposure effect to be a case of latent inhibition. The remaining experiments investigated the effects of pre-exposing the flavour in a context different from that used for conditioning. It was found (Experiment 2) diat latent inhibition transferred perfectly when the context change consisted of a move from one home cage to another. Context specificity of latent inhibition was found (Experiment 3) only when the subjects were given daily sessions in die experimental contexts, these being cages different from the home cage.     

Life strains,coping, and emotional well-being: A longitudinal study of recently separated and married women

The stress and coping paradigm was used as the framework for a longitudinal study of recently separated and married women. Data were gathered at three different interviews over a period of 18 months. Comparing the two groups of women, it was found that life strains in the areas of financial concerns and spouse relations were related to both income level and marital status, with low-income and separated women experiencing the highest levels of these strains. Also, the separated women used coping strategies emphasizing personal change and reported more positive changes related to their family, work, and material conditions. Regression analyses on the entire sample showed that life strains were inversely related to emotional well-being and that coping served a stress-buffering function. It was concluded that the emotional well-being of separated and married women must be considered in the context of stress, coping, and change processes.     

Origins of the misplaced confidence effect in collaborative recall

Studies have shown that dyads and groups place significantly more confidence in wrong answers to questions about a jointly witnessed event than do individuals. This experiment was designed to discover whether this misplaced confidence is influenced by prior free collaborative recall of the events in question. The results clearly indicated that prior group remembering lessens the effect, and improves the testimonial validity of both individual and group answers to questions about a jointly witnessed event. Taken in conjunction with other studies, the results imply that two or more witnesses of an event may profitably discuss what happened, but that they may best be interrogated separately in order to maximize the information available to the interrogator and to minimize misplaced confidence.     

Anger and irrational thought: Questionnaire and interview ratings

From an initial pool of 96 students, 36 subjects were selected based on Novaco Anger Scale scores to form high-, moderate-, and low-anger groups (n=12). They completed self-report questionnaires and participated in a structured interview designed to elicit cognitive and affective responses to hypothetical situations involving interpersonal conflict. High- and moderate-anger groups scored significantly higher than low-anger subjects on a questionnaire measure of irrational thinking. High-anger subjects scored higher than low-anger subjects on general anxiety, suspiciousness, fear of negative evaluation, hostility, and criticism of themselves and others. Interview ratings showed that there were no group differences in self-reports of anger or ability to cope with conflict, yet raters judged high-anger subjects to display more anger than low-anger subjects in their stated response actions. Estimates of coping ability varied inversely with reports of anger experienced. Generally, results support a relationship between irrational thinking patterns and anger in feeling and action. Implications for treatment are discussed.     

Girls and Engineering: Perceived Influences on Career Choice amongst Female Craft and Technician Engineers and Non-Engineers

There are very few women who take up careers as engineers - especially at the non-professional level. The present research attempts to throw some light on this issue, examining by means of a postal questionnaire the educational experiences of 22 young women craft and technician apprentices in a variety of engineering jobs. Comparisons are made with 33 similar young women who have chosen more traditional 'female' occupations. The results show significant differences between engineers and non-engineers in terms of their subject choices and curriculum opportunities at school and their perceptions of the attitudes of parents to wards their careers. Possible implications of the findings for developments in curriculum planning and careers guidance are explored.     

Schedule-induced behavior in hyperactive children

A schedule-induced behavior paradigm was used to investigate the activity patterns of hyperactive children in a standardized situation. In Experiment I, 10 hyperactive and 10 normal control children matched for age, sex, and IQ were observed under conditions of baseline and schedule. Measures of a number of categorized activities were taken on a time-sampling basis. Hyperactive children were more active than controls in baseline and did not respond to the schedule, unlike the controls who became significantly more active in schedule conditions. In Experiment II, 12 hyperactive and 6 normal children were again subjected to the same experimental paradigm, but in two of the four experimental sessions the stimulant drug methylphenidate was administered in an attempt to reduce the amount of baseline activity. Results were substantially similar to those of Experiment I, with hyperactive children more active than controls in baseline and insensitive to the schedule. There was no overall effect of drug administration on the behavior of either group. There were some ratedependent effects of both drug and schedule conditions.
