The Role of Injury and Trauma-Related Variables in the Onset and Course of Symptoms of Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) affects a minority of trauma-exposed persons and is associated with significant impairment. This longitudinal study examined risk factors for PTSD. We tested whether the presence of injuries resulting from trauma exposure predicted the course of PTSD symptoms. In addition, we tested whether gender, trauma type, perceived life threat, and peritraumatic dissociation predicted the onset of PTSD symptoms. 236 trauma-exposed civilians were assessed for PTSD symptoms with a structured interview at four occasions during 6 months posttrauma. Path analysis showed that a model in which the female gender, assault, perceived life threat, and peritraumatic dissociation predicted PTSD severity at 1 week, and injury predicted PTSD severity 8 weeks after the traumatic event showed the best fit. However, a similar model without injury showed comparable fit. It is concluded that injuries have a negligible effect on the course of PTSD.     

Taxonomy of the psychosocial consequences caused by the violence of persecution of ETA's network

This paper delimits and analyzes the effects of the harassment perpetrated by ETA's terrorist network in the Basque Country. The aim was to provide a taxonomy of the consequences of psychological violence and to validate this taxonomy, by means of a content analysis of 37 testimonies of victims of terrorist violence. The taxonomy of consequences of psychological violence is made up by four components: 1. the effects on the context of the persons affected, 2. on their emotional state, 3. on cognition and 4. on behavior. Results show a predominance of contextual consequences and negative cognitions. Intra-observer and inter-observer reliability analysis showed high stability and reproducibility coefficients. This study shows that harassment and psychological violence have major consequences not only for victims but also for family members, threatened collectives and even the society as a whole.     

Personality as a moderator of context effects on academic achievement

We investigated whether personality moderates group influence of classmates on academic achievement and whether these so-called context effects can be attributed to peer pressure. The sample consisted of 2498 students in their first year of Dutch secondary education. The data were analyzed by a two-level (students within classes) analysis, separately for boys (n = 1033, in 92 classes) and girls (n = 1465, in 119 classes). For both sexes, we found a context effect on Dutch language achievement but not on mathematics achievement. Emotional Stability appeared a moderator of this context effect but for girls only. The results suggest further that peer pressure is not a likely mechanism of group influence of classmates on academic achievement.     

Satisfaction with Life and Food-Related Life in Persons of the Mapuche Ethnic Group in Southern Chile: A Comparative Analysis Using Logit and Probit Models

In order to identify variables which have an influence on satisfaction with life among Mapuche persons of the Araucanía Region, Chile, a survey was applied to 400 Mapuche subjects in Temuco. The questionnaire included the SWLS (Satisfaction with Life Scale) and SWFL (Satisfaction with Food-related Life) scales, life-styles, food, and sociodemographic characteristics. Multinomial logit and probit models were proposed, in which the dependent variable was satisfaction with life. Both models proved significant (P < 0.01), but the logit model provided a better explanation of the construct. The results indicate a significant relation between satisfaction with life on the one hand and access to means of satisfying the basic needs associated with the concept of quality of life and maintenance of identity on the other. The probability of a high degree of satisfaction with life in a Mapuche person rises if he (she) possesses a greater number of goods, lives in the country, has higher education, has a partner, spends more than Ch 100,000 (US100,000 (US 200) per month on food, frequently consumes Mapuche food, leads an orderly life and is satisfied with his food. The discussion relates the results to the factors which influence the construction of cultural identity and the impact on this of traditional food practices     

Psychometric and CT scan measurements in a case of crossed aphasia in a dextral

A case of crossed aphasia with lesion deep to the right supramarginal gyrus was studied to determine (1) if this patient behaved similar to patients with the same lesion site in the left hemisphere, (2) if visuospatial deficits were present, and (3) if the CT scan asymmetries were similar to those of other right-handers. Speech and language skills were similar to those patients with similar lesions in the left hemisphere. Visuospatial and arithmetic deficits were similar to those described after right-hemisphere and left-hemisphere damage. CT scan asymmetries were atypical. These results provide behavioral and neuroradiological confirmation of atypical hemispheric dominance.     

Improving Predictions of Condom Behavioral Intentions With Partner-Specific Measures of Risk Perception

Inconsistent findings regarding the predictive validity of perceptions of risk for a sexually transmitted disease (STD) and HIV may be related to the use of nonspecific measures. The objective of this study was to determine whether more specific measures of perceptions of risk for SI Ds and HIV are associated with intentions to use a condom. We interviewed 490 male and female adolescents, 14 to 19 years old, from a free municipal STD clinic. Controlling for whether a condom was used at last sex, the association between perceptions of risk for an STD and HIV with a casual sex partner and intentions to use a condom with a casual sex partner was significant (β_HIV= 14, p < .01, and β_STD=.20, p < .01), as was the association between perceptions of risk for an STD and HIV with a main sex partner and intentions to use a condom with a main sex partner (β_HIV= .31, p <.001, and β_STD= .32, p < .001). This supports the continued inclusion of this construct in models of sexual and other health-related behaviors.     

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.     

Perceptual expertise enhances the resolution but not the number of representations in working memory

Despite its central role in cognition, capacity in visual working memory is restricted to about three or four items. Curby and Gauthier (2007) examined whether perceptual expertise can help to overcome this limit by enabling more efficient coding of visual information. In line with this, they observed higher capacity estimates for upright than for inverted faces, suggesting that perceptual expertise enhances visual working memory. In the present work, we examined whether the improved capacity estimates for upright faces indicates an increased number of "slots" in working memory, or improved resolution within the existing slots. Our results suggest that perceptual expertise enhances the resolution but not the number of representations that can be held in working memory. These results clarify the effects of perceptual expertise in working memory and support recent suggestions that number and resolution represent distinct facets of working memory ability.
