Combat Exposure and Posttraumatic Stress Disorder Among Portuguese Special Operation Forces Deployed in Afghanistan

Several combat- and noncombat-related stressors have been reported in Afghanistan. There is now accumulating evidence that suggests that posttraumatic stress disorder (PTSD) is linked to combat experiences; however, little is known about how these exposures might affect elite combat troops. This research aims to evaluate the prevalence of combat and noncombat related stressors, as well as PTSD in Portuguese Special Forces deployed in Afghanistan. Overall, participants reported high levels of exposure to combat and adverse physical conditions but also high levels of within-unit comradeship. The analysis also exposed that 2.7% of the participants reported symptoms compatible with PTSD and 8.8% with compatible partial PTSD. When the authors conducted a binary logistic regression, only the higher levels of combat exposure explained the symptoms of PTSD.

We examined how culture influences perceptions of applicant attributes when assessing employment suitability. In two studies (N = 408), we compared members from a collectivistic society (Singapore) to two samples from individualistic societies (the United States and Australia) on their perceptions of applicant attributes across job contexts. For each job, participants either chose between candidates with different attribute profiles or created ideal candidates by allocating a fixed amount of percentile points across different attributes. More often than Australians, Singaporeans chose the candidate with higher levels of the trait (e.g., openness to experience) uniquely associated with the job (e.g., graphic designer). More so than either Americans or Australians, Singaporeans prioritized having the trait most associated with each job. Members from collectivistic societies may require higher levels of the traits most associated with different jobs than members from individualistic societies, who prefer more well-rounded individuals for each job. As discussed, the study of lay perceptions may have implications for training hiring professionals and managers.     

The Development of Proportional Reasoning: Effect of Continuous Versus Discrete Quantities

This study examines the development of children's ability to reason about proportions that involve either discrete entities or continuous amounts. Six-, 8- and 10-year olds were presented with a proportional reasoning task in the context of a game involving probability. Although all age groups failed when proportions involved discrete quantities, even the youngest age group showed some success when proportions involved continuous quantities. These findings indicate that quantity type strongly affects children's ability to make judgments of proportion. Children's greater success in judging proportions involving continuous quantities appears to be related to their use of different strategies in the presence of countable versus noncountable entities. In two discrete conditions, children—particularly 8- and 10-year-olds—adopted an erroneous counting strategy, considering the number of target elements but not the relation between target and nontarget elements, either in terms of number or amount. In contrast, in the continuous condition, when it was not possible to count, children may have relied on an early developing ability to code the relative amounts of target and nontarget regions.     

Varied Input Stimuli and Motor Learning,

75 apparatus-naive undergraduate Ss were assigned to one of five groups differentiated according to training display associated with a modified rotary pursuit (RP) apparatus. Performance of two control groups, one practicing an unaided reference task and the other a pathmarked RP task, was compared with that of groups that received either path-marked or mechanically guided practice during training, and where path-marked and mechanical guidance display was removed during transfer. It was found that the path-marked display produced superior results only during initial stages of practice, and retarded improvement in performance after transfer to the reference task. Mechanical guidance resulted in better performance on the path-marked condition than the unaided RP task, but in both cases performance dropped upon transfer. The results are discussed in the light of hypothesized learning strategies influenced by different training conditions.     

Studies of Abnormal Behavior in the Rat: XVII. Guidance Versus Trial and Error in the Alteration of Habits and Fixations

Formation of a God concept, in accordance with the developmental hypothesis of object relations theory, includes the utilization of representations acquired within the context of significant relationships. Previous researchers have attempted to determine the comparative extent to which parent representations give rise to an individual's God image. In this study, we measured the similarities between subjects' composite parental ratings and their image of God. As predicted, the parental composite was significantly closer to the God rating than were the singular parent representations.     

The Use of Sulfanilamide in the Treatment of “Sniffles” in Rats

A nonprojective measure of achievement motivation, the Lynn Questionnaire (7), was administered to 67 Western Samoans, 34 Cook Islanders, 84 Maoris, and 103 European New Zealanders in an urban work environment in New Zealand. Results indicated that Western Samoans had lower achievement motivation levels than the other three groups, Cook Islanders were lower than European New Zealanders and equivalent to Maoris, and Maoris did not vary from European New Zealanders. Findings were interpreted as supportive of previous New Zealand research and in accordance with cultural assimilation theory.     

Kansas Physician Assistants’ Attitudes and Beliefs Regarding Spirituality and Religiosity in Patient Care

Research indicates patients want to discuss spirituality/religious (S/R) beliefs with their healthcare provider. This was a cross-sectional study of Kansas physician assistants (PA) regarding S/R in patient care. Surveys included questions about personal S/R beliefs and attitudes about S/R in patient care. Self-reported religious respondents agreed (92%) they should be aware of patient S/R; 82% agreed they should address it. Agreement with incorporating S/R increased significantly based on patient acuity. This research indicates Kansas PAs’ personal S/R beliefs influence their attitudes toward awareness and addressing patient S/R.     

Remembering the silver lining: Reappraisal and positive bias in memory for emotion

Reappraisal and distraction, unlike suppression, are known to decrease the intensity of negative emotion in the short term. Little is known about long-term characteristics associated with emotion regulation strategies, however. In a longitudinal study, we examined the relation between the strategies people reported using to regulate emotions during a stressful situation and their later memory for their emotions. Students in Italy rated the intensity of positive and negative emotions they were experiencing as they prepared for their high school exit exam. They also rated the extent to which they were regulating emotion using reappraisal, distraction, and suppression. Six weeks later, students recalled their pre-exam emotions. The more students reported engaging in reappraisal before the exam, the more they overestimated positive emotion and underestimated negative emotion when recalling their experience. The association between reported reappraisal and memory bias was partially mediated by positive changes over time in students’ appraisals of the exam preparation experience. Reports of engaging in distraction and suppression were not associated with memory bias. Because remembered emotion guides future choices, these findings suggest that reappraisal is a highly adaptive strategy for coping with stressful situations, not only in the short run, but also in the long run.
