Selective Association Between Tetris Game Play and Visuospatial Working Memory: A Preliminary Investigation

Recent experimental and clinical research has suggested that Tetris game play can disrupt maladaptive forms of mental imagery because Tetris competes for limited cognitive resources within visuospatial working memory (WM) that contribute to imagery. Whether or not Tetris performance is selectively associated with visuospatial WM remains to be tested. In this study, young adults (N = 46) completed six standardized measures indexing verbal and non‐verbal reasoning, verbal and visuospatial short‐term memory, and verbal and visuospatial WM. They also played Tetris. Consistent with the hypothesis that visuospatial WM resources support Tetris game play, there was a significant moderate positive relationship between Tetris scores and visuospatial WM performance but no association with other cognitive ability measures. Findings suggest that Tetris game play involves both storage and processing resources within visuospatial WM. These preliminary results can inform interventions involving computer games to disrupt the development of maladaptive visual imagery, for example, intrusive memories of trauma. © 2017 The Authors.

The impact of rewards on empathic accuracy and emotional mimicry

The notion that motivation influences empathic accuracy has been inferred from aspects of the task, the situation or the relationship between interaction partners or between groups. The present research assessed whether monetary reward influences cognitive and affective empathy. In Study 1, cognitive empathy was assessed for 42 participants who decoded briefly (33 ms) presented expressions of sadness and anger. For half the participants, correctly decoded expressions on male faces were rewarded, for the other half correctly decoded expressions on female faces were rewarded. The results showed that rewards increase empathic accuracy for both emotions equally. In Study 2, facial EMG was measured as well to assess emotional mimicry as an index of affective empathy. Study 2 replicated the findings from Study 1 and found a moderation of affective empathy as indexed through facial mimicry for sadness. Thus, simple monetary rewards affect both cognitive and affective empathy.     

Boys Don’t Work? On the Psychological Benefits of Showing Low Effort in High School

Male students show less academic effort and lower academic achievement than do female students. The present study aimed to shed more light on the reasons for why male students show low academic effort despite the finding that this undermines their academic achievement. We explored whether students experience psychological benefits from showing low effort or “effortless” achievement in school and whether these benefits are greater for male than for female students. In two experimental vignette studies with independent samples of German ninth graders (N?=?210) and teachers (N?=?176), we systematically varied student targets’ gender, effort, and achievement and tested for effects on targets’ ascribed intelligence, popularity, likeability, masculinity, femininity, and gender-typicality. The “effortless” achiever was rated as more popular than students showing high effort. Teachers perceived the effortless achiever as the most intelligent target. Academic effort further increased students’ ratings of a low-achieving target’s likeability and students’ and teachers’ ratings of all targets’ femininity as well as decreased students’ ratings of all targets’ masculinity. Students and teachers perceived targets showing low (vs. high) effort as more similar to a typical boy, whereas teachers perceived targets showing high (vs. low) effort as more similar to a typical girl. Results indicate a need to understand the psychological benefits of low academic engagement, especially for male students, and to address the feminine stereotyping of (academic) effort.     

PTSD symptom trajectories: from early to chronic response

This study aimed to identify posttraumatic stress disorder (PTSD) symptom trajectories across the first 12 months following traumatic injury. Three hundred and seven consecutively admitted injury survivors were assessed for severity of PTSD symptoms just prior to discharge, and at 3 and 12 months postinjury. Growth modeling was used to determine the curve that best fit the trajectory for each symptom cluster over the 12-month period. Individuals with 12-month PTSD showed significantly higher re-experiencing, arousal, and avoidance symptoms at eight days posttrauma relative to those without, and these symptoms escalated over time. Those without PTSD maintained their relatively low symptom levels. These findings highlight that individuals who will go onto develop PTSD have a distinctly different symptom course than those who recover.     

Should scientists think? Comment on Machado and Silva (2007)

The author has previously claimed that neural activity in a medial frontal brain area represents conscious motor intentions. A. Machado and F. J. Silva attempted to challenge this claim by arguing that such intentions are not necessarily causally effective and must be caused by something else, so that they therefore cannot be the unmoved first movers in action. The author's reply is that he made no such claims about the causal status and origin of conscious intentions. In fact, he has elsewhere presented empirical evidence in support of the idea that intentions are not necessarily causal. But this does not stop researchers from studying the neural basis for the conscious impression that one intends and wills one's actions. One can feel and attend to such intentions, be they causal or not. The author's claim is that there is neural activity in the medial frontal wall that reflects such conscious feelings. Other recent empirical evidence that supports this view is described.     

Genetic and environmental influences on interpersonal cognitions and associations with depressive symptoms in 8-year-old twins

Less is known about depression in children than in adults. This study integrates fields by combining cognitive and interpersonal research investigating childhood depression symptoms through the use of a genetic framework. Three research questions are addressed. First, what are the associations among interpersonal cognitions, anxiety, and depression? Second, what are the relative magnitudes of genetic and environmental influences on interpersonal cognitions? Third, to what extent do genetic and environmental influences explain associations between interpersonal cognitions and depression? Three hundred pairs of 8-year-old twins reported on symptoms of depression and anxiety by completing the Children's Depression Inventory and the Screen for Childhood Anxiety-Related Emotional Disorders. The authors examined interpersonal cognitions with the Children's Expectation of Social Behaviors and the Perceptions of Peers and Self Questionnaires. Interpersonal cognitions were more strongly correlated with depression (mean r = .35) than with anxiety (mean r = .13). Genetic influence on interpersonal cognitions was small (M = 3%), and associations between interpersonal cognitions and depression were mainly explained by environmental influences. These latter findings may result from interpersonal cognitions in young children, reflecting life experiences as opposed to trait-like cognitive biases.     

Nature and nurture: Williams syndrome across cultures

This study is concerned with ways in which children with Williams syndrome (WS), a rare neurodevelopmental disorder arising from a hemizygous deletion in chromosome band 7q11.23 including the gene for elastin (ELN) and approximately 20 surrounding genes, are affected by social mores of vastly differing cultures: the United States and Japan. WS presents a compelling model for the investigation because its genetic phenotype is well defined and results in an uneven cognitive profile as well as a social phenotype typical of the syndrome including overt over-friendliness toward strangers. While a number of research groups have been studying the cognitive strengths and weaknesses of individuals with WS in various countries, there have not been studies to date that explore the social phenotype in WS across different cultures. This study examines the ways in which social behavior in WS, stemming from specific genetic underpinnings, might be mediated by cultural expectations. We conducted a cross-cultural study using an instrument that measures aspects of sociability commonly found among people with WS. Quantitative analyses revealed a significant effect of diagnostic category in that in both countries, children with WS were rated as significantly higher in global sociability and more likely to approach strangers than were their normal counterparts. There was also an effect of culture, in that regardless of category, WS and normal children in Japan were rated lower than their counterparts in the US. We suggest that the excessively social phenotype of children with Williams syndrome, although markedly present across cultures, appears to vary in its intensity by culture. This is an intriguing illustration of interactions between nature and nurture.     

Does it only depend on the point of view? Perspective-related differences in justice evaluations of negative incidents in personal relationships

A series of four studies investigated systematic differences between actor and recipient interpretations and justice evaluations of negative incidents in interpersonal relationships. Due to a refined methodology, each negative incident was assessed both by the respective recipient and actor, and each participant reported incidents from both perspectives. The studies provided clear evidence of systematic recipient-actor differences and showed that the quality of the relationship between the parties involved in the incidents can moderate the occurrence and shape of the differences. Significant gender differences were found showing that women respond more accusingly than men in the role of the recipient and more defensively than men in the role of the actor.
