Predatory aggression in lines of wild mice selected for interfemale aggression

Mice descending from lines previously selected for high and low levels of interfemale aggression and from a nonselected control line were exposed to live crickets on two consecutive test days. Latencies both to attack and to eat the cricket were recorded. No line or sex differences in attacking were found, although latency to attack decreased over test days. Control line mice were more likely to engage in the eating of the cricket than either the high or low selected lines, suggesting that the selection procedure may have dissociated attacking and eating components of predatory behavior.     

The role of transportation in the persuasiveness of public narratives

Transportation was proposed as a mechanism whereby narratives can affect beliefs. Defined as absorption into a story, transportation entails imagery, affect, and attentional focus. A transportation scale was developed and validated. Experiment 1 (N = 97) demonstrated that extent of transportation augmented story-consistent beliefs and favorable evaluations of protagonists. Experiment 2 (N = 69) showed that highly transported readers found fewer false notes in a story than less-transported readers. Experiments 3 (N = 274) and 4 (N = 258) again replicated the effects of transportation on beliefs and evaluations; in the latter study, transportation was directly manipulated by using processing instructions. Reduced transportation led to reduced story-consistent beliefs and evaluations. The studies also showed that transportation and corresponding beliefs were generally unaffected by labeling a story as fact or as fiction.     

Lifetime and 12‐Month Nonsuicidal Self‐Injury and Academic Performance in College Freshmen

We examined whether nonsuicidal self‐injury (NSSI) is associated with academic performance in college freshmen, using census‐based web surveys (N = 7,527; response = 65.4%). NSSI was assessed with items from the Self‐Injurious Thoughts and Behaviors Interview and subsequently linked with the administratively recorded academic year percentage (AYP). Freshmen with lifetime and 12‐month NSSI showed a reduction in AYP of 3.4% and 5.9%, respectively. The college environment was found to moderate the effect of 12‐month NSSI, with more strongly reduced AYPs in departments with higher‐than‐average mean departmental AYPs. The findings suggest that overall stress and test anxiety are underlying processes between NSSI membership and academic performance.     

Neuroethical and Social Implications of Using Transcranial Electrical Stimulation to Augment Creative Cognition

Recent research indicates that transcranial electrical stimulation (tES) of specific brain regions can successfully improve various forms of creative cognition. Although the endeavor to increase human creative capacity is intriguing from a neuroscientific perspective, and of interest to the general public, it raises numerous neuroethico-legal and social issues (NELSI). This review explores these issues by considering (a) whether using brain stimulation to improve creative cognition qualifies as a ‘treatment’ or an ‘enhancement,’ (b) how direct-to-consumer (DTC) and do-it-yourself (DIY) use of tES should be regarded and regulated, and (c) what the developing landscape of creativity-related neurostimulation could (and should) become.     

Factors contributing to individual differences in facial expression categorisation

Individuals vary in perceptual accuracy when categorising facial expressions, yet it is unclear how these individual differences in non-clinical population are related to cognitive processing stages at facial information acquisition and interpretation. We tested 104 healthy adults in a facial expression categorisation task, and correlated their categorisation accuracy with face-viewing gaze allocation and personal traits assessed with Autism Quotient, anxiety inventory and Self-Monitoring Scale. The gaze allocation had limited but emotion-specific impact on categorising expressions. Specifically, longer gaze at the eyes and nose regions were coupled with more accurate categorisation of disgust and sad expressions, respectively. Regarding trait measurements, higher autistic score was coupled with better recognition of sad but worse recognition of anger expressions, and contributed to categorisation bias towards sad expressions; whereas higher anxiety level was associated with greater categorisation accuracy across all expressions and with increased tendency of gazing at the nose region. It seems that both anxiety and autistic-like traits were associated with individual variation in expression categorisation, but this association is not necessarily mediated by variation in gaze allocation at expression-specific local facial regions. The results suggest that both facial information acquisition and interpretation capabilities contribute to individual differences in expression categorisation within non-clinical populations.     

A Latent Profile Analysis of Co-occurring Youth Posttraumatic Stress and Conduct Problems Following Community Trauma

Although most research with youth exposed to violent manmade disasters has focused on internalizing problems, recent work suggests conduct problems (CPs) may also manifest in exposed youth. However, the extent to which youth postevent CPs present independently, versus co-present in conjunction with PTSD symptoms, remains unclear. The present study examined PTS and CP symptom profiles among affected Boston-area youth following the 2013 Boston Marathon bombing. This study used latent profile analysis to identify distinct PTS and CP symptom profiles among Boston-area youth ages 4–19 years (N?=?344) affected by the Boston Marathon bombing events. PTS and CPs were measured using the UCLA-PTSD-RI and the SDQ parent reports, respectively. Analyses identified 3 distinct profiles: presentations characterized by (a) low PTS, low CPs, (b) moderate PTS, low CPs, and (c) high PTS, elevated CPs. The profile characterized by the highest PTS was the only profile with elevated CPs; hyperarousal and emotional numbing/avoidance symptoms showed the greatest distinguishing properties among profiles with and without elevated CP. Types of traumatic exposure experienced by youth were differentially associated with profiles. Specifically, direct (but not relational) exposure distinguished youth classified in the profile showing elevated CPs. Findings suggest interventions following violent manmade disasters may do well to incorporate CP modules when working with youth showing the greatest hyperarousal and emotional numbing, and/or who have directly witnessed the most violence.     

Images of the disciplining of psychology, 1890–1940

Over the course of psychology’s first several decades, the language used to convey the subject matter gradually shifted from being free and literary to being strictly constrained and disciplined by increasingly focused theoretical demands. The project described here, “Disciplining Psychology,” aimed to depict this transformation by generating images of the faces of three highly influential psychologists—William James, Sigmund Freud, and B. F. Skinner. Each image is composed of the words used in one of each individual’s most important books. The tightening of the disciplinary vocabulary is revealed in the differences among the three arrays of words themselves, but I have also striven to reflect it in the aesthetic aspects of each image. The method used here could easily be extended to a wider array of authors, texts, and psychological topics.
