Memory for object locations: Priority effect and sex differences in associative spatial learning

This paper reports two experiments conducted to examine priority effects and sex differences in object location memory. A new task of paired position-learning was designed, based on the A–B A–C paradigm, which was used in paired word learning. There were three different paired position-learning conditions: (1) positions of several different objects (B-objects and C-objects) around referent objects (A-objects) were learned in the A–B A–C position-learning condition, (2) positions of several different objects with no referent objects were learned in the 0–B 0–C position-learning condition, and (3) positions of identical objects (stars) with no referent objects were learned in the 0-star 0-star position-only condition. The results revealed a significant priority effect on performance in the A–B A–C and the 0–B 0–C position-learning conditions but not in the 0-star 0-star position-only condition. Contradictory results were obtained with respect to the sex variable: a female superiority effect on paired position learning was significant in Experiment 1, but this effect was not replicated in Experiment 2. In addition, an articulatory suppression task used in Experiment 2 had a significant effect on recall of different object positions but no effect on recall of identical object positions. This suggested that verbal encoding was not necessary for learning of positions of identical objects.     

Context matters: the benefits and costs of expressing positive emotion among survivors of childhood sexual abuse

Positive emotions promote adjustment to aversive life events. However, evolutionary theory and empirical research on trauma disclosure suggest that in the context of stigmatized events, expressing positive emotions might incur social costs. To test this thesis, the authors coded genuine (Duchenne) smiling and laughter and also non-Duchenne smiling from videotapes of late-adolescent and young adult women, approximately half with documented histories of childhood sexual abuse (CSA), as they described the most distressing event of their lives. Consistent with previous studies, genuine positive emotional expression was generally associated with better social adjustment two years later. However, as anticipated, CSA survivors who expressed positive emotion in the context of describing a past CSA experience had poorer long-term social adjustment, whereas CSA survivors who expressed positive emotion while describing a nonabuse experience had improved social adjustment. These findings suggest that the benefits of positive emotional expression may often be context specific.     

International physical activity questionnaire: reliability and validity of the Turkish version

Physical inactivity is a global problem which is related to many chronic health disorders. Physical activity scales which allow cross-cultural comparisons have been developed. The goal was to assess the reliability and validity of a Turkish version of the International Physical Activity Questionnaire (IPAQ). 1,097 university students (721 women, 376 men; ages 18-32) volunteered. Short and long forms of the IPAQ gave good agreement and comparable 1-wk. test-retest reliabilities. Caltrac accelerometer data were compared with IPAQ scores in 80 participants with good agreement for short and long forms. Turkish versions of the IPAQ short and long forms are reliable and valid in assessment of physical activity.     

A Meta‐analysis of Letters of Recommendation in College and Graduate Admissions: Reasons for hope

Letters of recommendation are used extensively in academic admissions and personnel selection. Despite their prominence, comparatively little is known about their predictive power for multiple outcomes. This meta‐analysis combine the existing literature for college grade point average (GPA), academic outcomes of GPA, performance ratings, degree attainment, and research productivity for nonmedical school graduate programs, and GPA and internship performance ratings for medical school students. Intercorrelations with other commonly used predictors are also estimated and used to estimate incremental predictive power. Overall, letters of recommendation, in their current form, are generally positively but weakly correlated with multiple aspects of performance in post‐secondary education. However, letters do appear to provide incremental information about degree attainment, a difficult and heavily motivationally determined outcome.     

Introducing the Special Section on Openness to Experience: Review of Openness Taxonomies,Measurement, and Nomological Net

In this introduction to the Special Section on Openness to Experience, we review the historical background of the construct and its measurement. We also provide a meta-analytically based review of its broader nomological net. Specifically, we review relationships with other individual differences constructs, including personality traits, interests, and cognitive ability. We highlight the various roles that openness and intellect play in educational performance, occupational attitudes and behaviors, job performance, career success, and psychological health and well-being. In doing so, we emphasize the unique contributions of the articles published in this special section (Albrecht, Dilchert, Deller, & Paulus; Connelly, Ones, Davies, & Birkland; DeYoung, Quilty, Peterson, & Gray; Roets, Cornelis, & Van Hiel; Woo, Chernyshenko, Longley, Zhang, Chiu, & Stark; Woo, Chernyshenko, Stark, & Conz). Finally, we note fruitful venues for future research involving Openness constructs.     

Integrity tests predict counterproductive work behaviors and job performance well: comment on Van Iddekinge, Roth, Raymark, and Odle-Dusseau (2012)

Examination of the Van Iddekinge, Roth, Raymark, and Odle-Dusseau (2012) meta-analysis reveals a number of problems. They meta-analyzed a partial database of integrity test validities. An examination of their coded database revealed that measures coded as integrity tests and meta-analyzed as such often included scales that are not in fact integrity tests. In addition, there were important deficiencies in their analytic approach relating to application of range restriction corrections and identification of moderators. We found the absence of fully hierarchical moderator analyses to be a serious weakness. We also explain why empirical comparisons between test publishers versus non-publishers cannot unambiguously lead to inferences of bias, as alternate explanations are possible, even likely. In light of the problems identified, it appears that the conclusions about integrity test validity drawn by Van Iddekinge et al. cannot be considered accurate or reliable.     

A twin study of computer anxiety in Turkish adolescents

The present study investigated computer anxiety within a sample of Turkish twins aged 10-18. A total of 185 twin-pairs participated in the study. Of the twins, 64 pairs (34.6 percent) were monozygotic (MZ) and 121 pairs (65.4 percent) were dizygotic (DZ). Of the 121 DZ twins, 54 pairs (44.63 percent) were same-sex twins and 67 pairs (55.37 percent) were opposite-sex twins. Computer anxiety was assessed using Computer Anxiety Rating Scale-Turkish Version (CARS-TV), one of the three main scales of "Measuring Technophobia Instruments" developed by Rosen and Weil. The results of paired t test comparisons showed no significant differences in MZ and same-sex DZ twin-pairs' levels of computer anxiety. On the other hand, a significant difference was found in opposite-sex DZ twin-pairs' level of computer anxiety. Interesting enough, males appeared to be more computer anxious than their female co-twins. In the present study, using Falconer's formula, heritability estimate for computer anxiety was derived from correlations based on MZ and DZ twins' mean scores on CARS-TV. The results showed that 57 percent of the variance in computer anxiety was from genetics and 41.5 percent was from nonshared environmental factors. Shared environmental influence, on the other hand, was very small and negligible. Interpretations of results and potential directions for future research are presented.
