Object-based and egocentric mental rotation performance in older adults: The importance of gender differences and motor ability

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability.     

Feeling body dissatisfied after viewing thin-ideal pictures is mediated by self-activation

The present study sought to investigate the influence of self-activation on body and weight satisfaction in restrained and unrestrained eaters, after exposure to thin-ideal images. Restrained eaters (n = 39) and unrestrained eaters (n = 40) were randomly assigned to a self-activation manipulation versus a control manipulation. After the manipulation, all participants were exposed to eight thin-ideal images. Measures of state body and weight satisfaction and of social comparison tendencies were assessed throughout the experiment. Self-activated restrained eaters showed a significant decrease in body and weight satisfaction after exposure to thin-ideal images, compared to restrained eaters who were not self-activated. In unrestrained eaters, the self-activation manipulation did not have any effect on body or weight dissatisfaction. In conclusion, exposure to fashion models only had a negative influence on women's self-evaluations when two conditions were met: (1) the participant was ‘self-activated’ and (2) the participant classified as a restrained eater.     

The Stroop Color-Word Interference Test as an Indicator of ADHD in Poor Readers

The performance on the Stroop Color-Word Interference Test of 36 boys with Attention Deficit Hyperactivity Disorder (ADHD) was compared with performances of a matched control sample. The control group outperformed their counterparts on the control and interference conditions of the Stroop test, suggesting ADHD-specific executive and reading deficits. When individuals with both ADHD and reading disorders were excluded from the analysis, the authors found a significant difference between the ADHD group and the control group on the color-word test, indicating that poor reading skills may produce false negatives on the Stroop test. However, fast and slow readers with ADHD did not perform differently from each other on the color-word test. The authors postulated the existence of two different causes of reading problems: phonological deficits and attentional deficits.     

Health psychology in international perspective: A summary and some thoughts for the future

This article reviews the progress made by the field in its short history and attempts to look at developments which seem likely to occur as the field matures.

Recommendations are made for training of health psychologists in the future and a plea is made for international standardisation of health psychology training programmes at the Ph.D. level which incorporate research and clinical training. Health psychologists are further encouraged to take a more active public and political role in order to provide needed visibility for their work.     

The effects of smoking norms and attitudes on quitting intentions in Malaysia,Thailand and four Western nations: A cross-cultural comparison

This research investigated the influence of smoking attitudes and norms on quitting intentions in two predominantly collectivistic countries (Malaysia and Thailand) and four predominantly individualistic Western countries (Canada, USA, UK and Australia). Data from the International Tobacco Control Project (N = 13,062) revealed that higher odds of intending to quit were associated with negative personal attitudes in Thailand and the Western countries, but not in Malaysia; with norms against smoking from significant others in Malaysia and the Western countries, but not in Thailand; and with societal norms against smoking in all countries. Our findings indicate that normative factors are important determinants of intentions, but they play a different role in different cultural and/or tobacco control contexts. Interventions may be more effective if they are designed with these different patterns of social influence in mind.     

Personality,Autonomy, and Contextual Performance of Managers

This study contributes to research on assessment centers' (AC) external construct-related validity by investigating a potential moderator of the relationship between personality and AC dimension ratings. On the basis of recent insights in person-situation contingencies we hypothesized that individual differences in people's perception of situational demands moderate the relationship between personality and conceptually related AC dimension ratings. The hypotheses were tested with 108 individuals in two leaderless group discussion exercises. Results confirmed the hypotheses for two of the three traits (i.e., Agreeableness and Conscientiousness). In particular, people high on these traits who identified the situational demands received higher AC dimension ratings. People high on these traits who did not identify the situational demands received lower AC dimension ratings.     

Differentiating Gender Discrimination and Sexist Behavior: An Examination of Antecedents and Outcomes

The United States Defense Manpower Data Center (DMDC) currently assesses gender discrimination and sexist behavior separately in its surveys of active duty and reserve service members. However, based on their definitional and theoretical similarities, it is possible that the two constructs may overlap to some extent. Using a military sample of 8,123 female respondents, this issue was examined using path analysis. The results of this study show that gender discrimination and sexist behavior are predicted by several common antecedent variables. In addition, each construct is shown to predict both common and unique outcomes. Implications for the organizational assessment of sexist behavior and gender discrimination are discussed.     

Optimizing Prediction of Attrition With the U.S. Army's Assessment of Individual Motivation (AIM)

The regression framework is often the method of choice used by psychologists for predicting organizationally relevant outcomes from test scores. However, alternatives to regression exist, and these techniques may provide better prediction of outcomes and a more effective means of classifying examinees for selection and placement. This research describes two of these alternatives—decision tree methodology and optimal appropriateness measurement (OAM)—and how they were used to optimize the prediction of attrition among a sample of first-term enlisted soldiers (N?=?22,537) using a temperament inventory called the Assessment of Individual Motivation (AIM). Results demonstrated that the OAM approach provided better differentiation between “stayers” and “leavers” after 12 months than either the traditional logistic regression or the decision tree methods.     

EXPERIENTIAL NARRATIVES OF RAPE AND TORTURE

Many Guatemalan women suffered extreme sexual violence during the latter half of the twentieth century. Learning of this violence can evoke hatred in persons who love and respect women—hatred for the men who perpetrated the violence and also for other men around the world who victimize women in this way. Hatred is a common response to a perceived evil, and it might in some cases be a fitting response, but it is important to subject one's emotions to critical moral reflection. A key task of ethics is to encourage persons to cultivate good habits of being moved. This essay analyzes the way in which two different texts manage, through the skillful presentation of experiential narratives, to help readers acknowledge the hatred they might feel, but also to think twice about the hatred to which they consent.     

Cognitive aspects of congenital learned helplessness and its reversal by the monoamine oxidase (MAO)-B inhibitor deprenyl

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs on the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher ‘anxiety’ or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4–5 per group), chronic treatment with a high dose of the monoamine oxidase (MAO)-B inhibitor deprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or ‘anxiety’ in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning.
