Judging Knowledge in the Digital Age: The Role of External‐Memory Organization

Two studies examined relations between features of external‐memory repositories (personal computers) and confidence in knowing. Participants judged their confidence in knowledge related to their work or studies and then answered questions about the way they store and use information. Participants who maintained more organized repositories were more confident in their knowledge. Furthermore, moderation analyses showed that the participants who navigated through their files by manually clicking through folders to find documents, but not those who use an automated search feature, felt more knowledge confident if they maintained a well‐organized electronic repository. These results provide evidence for relation between assessments of internally ‘stored’ knowledge and the degree of organization of their externally stored ‘knowledge.’ Copyright © 2016 John Wiley & Sons, Ltd.     

Do gray wolves (<Emphasis Type="Italic">Canis lupus</Emphasis>) support pack mates during aggressive inter-pack interactions?

For group-living mammals, social coordination increases success in everything from hunting and foraging (Crofoot and Wrangham in Mind the Gap, Springer, Berlin, 2010; Bailey et al. in Behav Ecol Sociobiol 67:1–17, 2013) to agonism (Mosser and Packer in Anim Behav 78:359–370, 2009; Wilson et al. in Anim Behav 83:277–291, 2012; Cassidy et al. in Behav Ecol 26:1352–1360, 2015). Cooperation is found in many species and, due to its low costs, likely is a determining factor in the evolution of living in social groups (Smith in Anim Behav 92:291–304, 2014). Beyond cooperation, many mammals perform costly behaviors for the benefit of group mates (e.g., parental care, food sharing, grooming). Altruism is considered the most extreme case of cooperation where the altruist increases the fitness of the recipient while decreasing its own fitness (Bell in Selection: the mechanism of evolution. Oxford University Press, Oxford 2008). Gray wolf life history requires intra-pack familiarity, communication, and cooperation in order to succeed in hunting (MacNulty et al. in Behav Ecol doi: 10.1093/beheco/arr159 2011) and protecting group resources (Stahler et al. in J Anim Ecol 82: 222–234, 2013; Cassidy et al. in Behav Ecol 26:1352–1360, 2015). Here, we report 121 territorial aggressive inter-pack interactions in Yellowstone National Park between 1 April 1995 and 1 April 2011 (>5300 days of observation) and examine each interaction where one wolf interferes when its pack mate is being attacked by a rival group. This behavior was recorded six times (17.6 % of interactions involving an attack) and often occurred between dyads of closely related individuals. We discuss this behavior as it relates to the evolution of cooperation, sociality, and altruism.     

Social identity and psychosis: Explaining elevated rates of psychosis in migrant populations

A substantial body of literature suggests that migrants are at greater risk of developing psychotic symptoms, such as paranoia, compared to non‐migrants. To date, researchers have been unable to identify the primary cause of this effect, finding scarce support for biological, diagnostic, and economic explanations. Social determinants have received little empirical attention in this domain, which we assert is a critical gap in the literature. Here, we propose that the social identity approach offers a framework to help explain the elevated rates of psychosis among migrants, and in turn inform policies and interventions to address this important mental health issue. We propose that cultural identities play a central role in mitigating the psychological precursors of psychosis and that disidentification and social disconnection subsequent to migration could initiate or exacerbate psychosis for multiple generations. We draw together research from social and clinical psychology to detail a social identity approach to psychosis in migrant populations, and make recommendations for future research.     

Promoting an Empathic Dialectic for Therapeutic Change: An Integrative Review

This integrative review is focused on a formulation of therapeutic empathy. We describe the “empathic dialectic” as therapists’ capacity to emotionally resonate with patients’ internal states, such as during ruptures, and to coregulate their own and the patients’ states through mentalization. The first aim was to provide a theoretical framework for the empathic dialectic, by summarizing background literature on the empathic process, intersubjectivity, rupture repair, relational psychoanalysis, and attachment. The second aim was to conduct an integrative review of peer-reviewed articles published between the years of 2016 and 2021. After conducting a review of 28 articles, we sought to identify (1) research that supports the existence of an empathic dialectic, (2) evidence that therapists’ attachment influences the empathic dialectic, and (3) implications of the empathic dialectic for training and supervision. Results pointed to the central role of therapists’ attachment security in the empathic dialectic, and the negative repercussions of therapists’ insecurity when mentalization is underdeveloped. Results also highlighted the role of supervision as a means of enhancing trainees’ self-awareness of their attachment, and its impact on the alliance. As the American Psychological Association embraces a clinical competencies model in its accreditation of clinical psychology doctoral programs, the importance of attaining an integrative understanding of therapeutic empathy has become increasingly imperative. To this end, we conclude by promoting the empathic dialectic as a key clinical competency, and providing further recommendations for training and supervision.

     

Female Self-Sexualization in MySpace.com Personal Profile Photographs

This article reports the results of a content analysis of female self-sexualization in personal profile pictures on MySpace.com (N = 24,000). Photographs were analyzed according to three measures: ritualization of subordination, body display, and objectification. Trained evaluators coded the photographs for each measure by race/ethnicity, body type, sexual orientation, and education level. Findings reveal that rates of ritualization of subordination were significantly higher for Hispanics, average body types, and bisexuals. Body display and objectification were both significantly higher for Blacks and Hispanics, bisexuals, and women with higher education levels. Body display and objectification rates were significantly lower for larger body types while body display alone was significantly lower for lesbians. Overall self-sexualizing behavior in this study sample is low based upon study measures. Images presented on MySpace.com do reveal, however, an acceptance of constrained and stereotypical notions regarding both gender and sex roles.     

Development and exploratory cluster-randomised opportunistic trial of a theory-based intervention to enhance physical activity among adolescents

This article reports the development and exploratory testing of a school-based intervention programme designed to enhance levels of physical activity in adolescents. The intervention is based on social cognitive theory (SCT), self-regulation theory (SRT) and planning as evidence-based mediators of physical activity changes. Two classes, paired on socio-economic variables, were selected from each of eight Portuguese schools and randomly assigned to an intervention or control group (N = 291). Primary outcome was ‘moderate to vigorous physical activity’ (International Physical Activity Questionnaire) measured pre and post intervention and at three and nine months follow-up. SCT, SRT and planning variables were secondary outcomes measured pre and post intervention. At post test, participants in the intervention group reported 18 min per week more physical activity (PA), adjusted for pre-intervention, age and sex, than those in the control group (95% confidence interval ?10 to 46; p = 0.249). This difference increased to 33 min (95% CI–4 to 71; p = 0.082) at three months and to 57 min (95% CI 13 to 101, p = 0.008) at nine month follow-up. Moreover, the intervention resulted in changes of some of the theoretical target variables, including outcome expectancies and coping planning. However, no evidence was found for the changes in theoretical moderators to mediate the intervention effects on behaviour. Implications for theory and for future research are discussed.     

Improving Discrimination and Face Matching with Caricature

Identification of faces from photographs is a common security measure, but matching unfamiliar faces produces high rates of error. Caricatures of familiar people are highly identifiable because they exaggerate distinctive features. We investigated whether exaggerating unfamiliar faces through caricaturing could also improve face‐matching accuracy. In Experiment 1, face‐matching arrays were caricatured relative to an average by 30%, 50% and 70%. Correct rejection of the target‐absent arrays was improved at all levels. Accurate matches increased at 30%, but at 70%, the transformation was too extreme, and all of the arrays were more likely to be rejected. In Experiment 2, photographic identification (ID) images were caricatured by 30% and 50% and matched to life‐size photographs. Rejection of foils improved, but the ID of matching images was impaired. Modest levels of caricature may improve discrimination in unfamiliar face matching, but at stronger levels, a conservative response bias may inhibit accurate ID.

Changes in Limb Stiffness Under Conditions of Mental Stress

In 2 experiments, the effects of mental stress on limb stiffness were investigated. The relative contribution to arm stiffness of individual muscle activity, co-contraction, muscle reflexes, and postural adjustments were examined. In each experiment, participants (N = 24, Experiment 1; N = 16, Experiment 2) held their supinated hand under a tray that they were required to return to horizontal after it had been suddenly released. Electromyographic activity in the biceps and triceps muscles was recorded, as were elbow and wrist angles and tray displacement. In Experiment 1, mental arithmetic stress was shown to lead to decreased tray displacement (i.e., increased resistance) compared with displacements under the control, unstressed condition, as well as to increased elbow flexion before tray release. In Experiment 2, the increased resistance to perturbation caused by mental stress was found to be independent of initial elbow angle, but to vary as a function of the amount of upward force exerted before tray release. The authors conclude that stress-induced increases in limb stiffness result from changes in the initial position of the elbow, specified by its angle, together with the initial force exerted by participants to counteract the mechanical perturbations.
