Digit ratio (2D:4D) and sensation seeking: New data and meta-analysis

Previously reported associations between low (male-typical) digit ratio (2D:4D), a putative pointer to prenatal testosterone exposure, and high (male-typical) sensation seeking have been inconsistent across studies (alternately present for men, women, either sex, or neither). Addressing this question again in three new studies (N = 198, 188, 1118) produced similarly erratic findings. Meta-analysis of the entire literature (13 studies with nearly 3000 individuals, including unpublished accounts) showed that the current cumulative evidence does not support any negative correlations between 2D:4D and sensation seeking traits. The only significant meta-analytical finding was for right-hand 2D:4D and the experience seeking facet of sensation seeking in both sexes, but this effect accounted for merely 0.4% attributable variance, and moreover was directionally opposite to expectation (i.e., a positive correlation). Discussed are inherent limitations of narrow-scoped approaches (such as via 2D:4D) for elucidating the biological bases of individual difference variables with evidentially intricate neurochemical underpinnings (such as sensation seeking).     

Cognitive-Behavior Therapy for Vietnamese Refugees With PTSD and Comorbid Panic Attacks

For Vietnamese refugees, we describe (a) how headache- and orthostasis-focused panic attacks are generated, (b) a culturally sensitive treatment for PTSD with comorbid headache- and orthostasis-focused panic attacks, and (c) the outcome of a treatment series. In a multiple-baseline, across-subjects design (N = 3), all patients demonstrated treatment-related improvement of headache- and orthostasis-associated panic attacks; and in the repeated-measures, within-subjects design, all patients greatly improved across treatment on measures of psychopathology. One treatment case is presented.     

Does Economic Inequality Affect the Quality of Life of Older People in Rural Vietnam?

By combining data from the 2011 Vietnam National Aging Survey and the 2011 Rural, Agricultural and Fishery Census, this study examined whether expenditure inequality has any effect on the quality of life (life satisfaction or happiness) among the elderly in rural Vietnam. It was confirmed from our regression analysis that individuals who live in the communes with high inequality tend to self-report as being less happy, even after controlling for various individual and household attributes. The findings are robust to the choice of inequality measures and the specification of econometric models. We also find that older rural people who are farmers or poor are more sensitive to inequality. Given that these people tend to be less happy than others, the result shows the risk that inequality further lowers their subjective well-being. This finding, in part, supports the view that rural Vietnam is not a mobile society.     

Exemplification Effects of Multimedia Enhancements

This research addresses multimedia effects through the lens of exemplification, thereby providing insight into consequences of using multimedia to embellish news content. Specifically, the study examines whether the vivid display of multimedia enhancements could influence the way people perceive issues reported in the accompanying stories. A 3 × 2 × 2 mixed factorial experiment was conducted with exemplar valence and exemplar vividness presented via multimedia elements and time of response serving as factors. According to the results, the content of multimedia additions created a shift in issue perception. The more interesting finding was the interaction effect of valence and vividness in multimedia exemplification. Valence of highly vivid exemplars was more likely to bias issue perception than did valence of non-vivid exemplars. This effect occurred in the presence of identical, two-sided textual content across all conditions. Theoretical and practical implications of the findings are discussed.     

Effects of training intensity on observers' ratings of anxiety, social skills, and alcohol-specific coping skills

Few studies have addressed the amount of training needed to obtain reliable ratings in behavioral observation data. The current study examined the effects of differing intensities of frame-of-reference (FOR) rater training on observers' ratings of anxiety, social skills, and alcohol-specific coping skills in community volunteers with and without social anxiety and alcohol use disorders. Interrater reliability was assessed by comparing three training conditions (no-training, moderate FOR, and intensive FOR) on discrepancies between raters'scores and the strength of association between raters'scoring patterns. The discrepancies between raters' scores were significantly larger in the control condition than in the intensive and moderate training conditions. Generally, small and nonsignificant differences were found between intensive and moderate training's discrepancy scores. Strength of association results showed significantly lower correlations in the control group compared to the intensive group. However, these correlational results showed less consistent differences between the moderate and other training conditions; differences when found were in the expected directions. Study findings suggest that differing training intensities can affect rating scores and that interrater reliability may be meaningfully assessed through multiple methods.     

How do we track invisible objects?

We previously demonstrated that observers in multiple object tracking experiments can successfully track targets when all the objects simultaneously vanish for periods lasting several hundred milliseconds (Alvarez, Horowitz, Arsenio, Dimase, &; Wolfe, 2005). How do observers do this? Since observers can track objects that move behind occluders (e.g., Scholl &; Pylyshyn, 1999), they may treat a temporal gap as a case of complete occlusion. If so, performance should improve if occlusion cues (deletion and accretion) are provided and items disappear and reappear one by one (asynchronously), rather than simultaneously. However, we found better performance with simultaneous than with asynchronous disappearance (Experiment 1), whereas occlusion cues were detrimental (Experiment 2). We propose that observers tolerate a gap in tracking by storing the current task state when objects vanish and resuming tracking on the basis of that memory when the objects reappear (a task-switching account).     

Sex differences in English language acculturation and learning strategies among Vietnamese adults aged 40 and over in the United States

This study examines sex differences in English language acculturation and learning strategies among older Vietnamese in the United States in a nationwide probability sample. Data of this study came from the Southeast Asian Refugee Self-Sufficient Study (1982). The results reveal that older Vietnamese women had more problems with their English language than older Vietnamese men. In addition, the Vietnamese men were more likely to use various learning strategies to improve their English skills than the women.     

Health, stress, psychological resources, and subjective well-being among older blacks

This study examines the structural relationships among sociodemographic characteristics, health status, stress, psychological resources, and subjective well-being (SWB) among the Black elderly. A structural equation model of SWB was evaluated with data from the 1979-1980 National Survey of Black Americans. The results revealed that poor subjective health status was predictive of lower levels of personal efficacy and SWB. Stressful life events tended to depress subjective assessments of health and had negative effects on self-esteem and SWB. Marital status and age had positive effects on SWB. Chronic health conditions and other demographic variables, however, had indirect effects on SWB.     

Cross‐national comparisons of attitudes towards suicide and suicidal persons in university students from 12 countries

This paper reports the results of a comparative investigation of attitudes to suicide and suicidal persons in 5,572 university students from 12 countries. Participants filled out two scales measuring attitudes towards suicide and suicidal persons, a measure of psychological distress together with the questions about suicidal behavior. Results showed that the highest suicide acceptance scores were observed in Austrian, UK, Japanese and Saudi Arabian samples and the lowest scores were noted in Tunisian, Turkish, Iranian and Palestinian samples. While the highest social acceptance scores for a suicidal friend were noted in Turkish, US, Italian and Tunisian samples, the lowest scores were seen in Japanese, Saudi Arabian, Palestinian and Jordanian samples. Compared to participants with a suicidal past, those who were never suicidal displayed more internal barriers against suicidal behavior. Men were more accepting of suicide than women but women were more willing to help an imagined suicidal peer. Participants with accepting attitudes towards suicide but rejecting attitudes towards suicidal persons reported more suicidal behavior and psychological distress, and were more often from high suicide rate countries and samples than their counterparts. They are considered to be caught in a fatal trap in which most predominant feelings of suicidality such as hopelessness or helplessness are likely to occur. We conclude that in some societies such as Japan and Saudi Arabia it might be difficult for suicidal individuals to activate and make use of social support systems.
