Caffeine does not modulate inhibitory control

The effects of a 3mg/kg body weight (BW) dose of caffeine were assessed on behavioral indices of response inhibition. To meet these aims, we selected a modified AX version of the Continuous Performance Test (CPT), the stop task, and the flanker task. In three double-blind, placebo-controlled, within-subjects experiments, these tasks were administered to healthy participants. While the results for the AX-CPT were indicative of improved response inhibition after caffeine, they might also reflect caffeine-induced changes in mechanisms other than response inhibition (e.g., attentional processes). The results for the stop task and flanker task were more straightforward. That is, the effects of caffeine on overall flanker performance and selective response suppression as revealed by distribution-analytical techniques were negligible. In the stop task a global effect of caffeine on processing speed was seen, rather than specific effects on response inhibition. Taken together, these experiments showed that both active and reactive inhibition were not significantly modulated by caffeine. The present results are linked to neural circuits that underlie inhibitory control and the role of caffeine-induced strategic changes.     

Group Treatment with Sexually Assaulted Male Veterans: A Year in Review

Rape of men by other men is a form of sexual assault that is incompletely addressed in the literature. As a result, little is known about the treatment interventions that are most effective for this population. We designed and conducted an ongoing process-oriented psychotherapy group for male veterans who were raped while serving in the military and/or sexually assaulted in childhood. Our experience with this group provided us with a better understanding of the behavioral, cognitive, and emotional issues presented by sexually assaulted males. We suggest that group therapy is an effective modality in treating this population.     

Stigma by Association Among Family Members of People with a Mental Illness: A Qualitative Analysis

People with mental illness are not the sole recipients of stigmatisation; their immediate family members may be subjected to stigma by association. Through semi‐structured interviews, we investigated experiences of stigma by association among 23 immediate family members of people with mental illness. Participants reported experiencing stigma by association from community members, mental health professionals, and civil servants. Familial relationship, co‐residence, and the gender of participants appeared to play a role in their stigma experiences; parents and spouses reported different manifestations of stigma by association than siblings and children, participants who lived together with their family member with mental illness reported increased experiences of stigma by association, and in contrast to male participants, female participants reported others thinking they are overprotective and as such perpetuated, maintained, or sustained their family members' mental illness. The relevance of these factors points to the need for tailored education and emotional support provision to family members of people with mental illness. Moreover, in‐service training for mental health professionals should include the development of relevant social skills that enable the recognition of familial relationships and roles, and family members' fears, concerns, and problems.

Socialization of prosocial behavior: Gender differences in the mediating role of child brain volume

Evidence has been accumulating for the impact of normal variation in caregiving quality on brain morphology in children, but the question remains whether differences in brain volume related to early caregiving translate to behavioral implications. In this longitudinal population-based study (N = 162), moderated mediation was tested for the relation between parental sensitivity and child prosocial behavior via brain volume, in boys and girls. Both maternal and paternal sensitivity were repeatedly observed between 1 and 4 years of age. Brain volume was assessed using magnetic resonance imaging measurements at age 8, and self-reported prosocial behavior of children was assessed at 9 years of age. Parental sensitivity was positively related to child brain volume, and to child prosocial behavior at trend level. Child brain volume was negatively related to child prosocial behavior. A significant gender-by-brain interaction was found, illustrating that daughters of sensitive parents were more prosocial and that less prosocial behavior was reported for girls with a larger total brain volume. Child gender significantly moderated the indirect effect of parental sensitivity on prosocial behavior via total brain volume. A significant indirect pathway was found only in girls. The results warrant replication but indicate the importance of considering gender when studying the behavioral implications of differences in brain volume related to early caregiving experiences.     

Analyzing nonverbal listener responses using parallel recordings of multiple listeners

In this paper, we study nonverbal listener responses on a corpus with multiple parallel recorded listeners. These listeners were meant to believe that they were the sole listener, while in fact there were three persons listening to the same speaker. The speaker could only see one of the listeners. We analyze the impact of the particular setup of the corpus on the behavior and perception of the two types of listeners: the listeners that could be seen by the speaker and the listeners that could not be seen. Furthermore, we compare the nonverbal listening behaviors of these three listeners to each other with regard to timing and form. We correlate these behaviors with behaviors of the speaker, like pauses and whether the speaker is looking at the listeners or not.     

Sub‐Dimensions of the Four Factor Model of Cultural Intelligence: Expanding the Conceptualization and Measurement of Cultural Intelligence

Cultural intelligence (CQ) – the capability to function effectively in intercultural settings – has gained increasing attention from researchers and practitioners due to its contemporary relevance to globalization, international management, and workforce diversification. Research‐to‐date demonstrates that CQ predicts a variety of important outcomes in intercultural contexts, such as cultural adaptation, expatriate performance, global leadership, intercultural negotiation, and multicultural team processes. Moving beyond past research that tends to focus on the four primary factors of CQ – metacognitive CQ, cognitive CQ, motivational CQ, and behavioral CQ, we introduce an expanded conceptualization of CQ that delineates sub‐dimensions for each of the four factors. We briefly review psychometric evidence supporting the proposed second order 11‐factor structure and convergent/discriminant validity of the sub‐dimensions. We propose that the next wave of CQ research should be guided by a deeper understanding of each of four factors of CQ.     

Meditation and Health: The Search for Mechanisms of Action

Psychological interest in the impact of mental states on biological functioning is growing rapidly, driving a need for new methods for inducing mental states that last long enough, and are sufficiently impactful, to have significant effects on physical health. The many traditions of meditative practice are one potential pathway for studying mind‐body interactions. The purpose of this review is to introduce personality and social psychologists to the field of meditation research. Beginning with a brief introduction to meditation and the heterogeneity of meditative practices, we showcase research linking meditative practice to changes in immune and cardiovascular functioning and pain perception. We then discuss theoretical and empirical evidence that meditation works by inducing changes in psychological capacities such as emotion regulation and self‐regulation or through repeated induction of specific mental states such as love or meta‐cognitive awareness. At the frontier of the science of meditation is the need to empirically test whether meditation‐driven changes in cognitive and affective processes are the cause of improvements in physical health. Emerging challenges in meditation research include a need for large studies using randomized controlled and dual‐blind designs with active control groups and an increased focus on measuring mechanisms of action as well as outcomes. Meditation represents a potentially powerful tool for generating new knowledge of mind‐body interactions.     

The Missing Link: On Strengthening the Relationship Between Values and Attitudes

Three experiments that test whether the activation of values may result in a change in the relationship between the activated value and connected attitudes are discussed. Participants were primed with the value universalism and subsequently asked for their attitude toward organically grown food. Our results strongly suggest that values are more likely to significantly influence attitudes when the relevant value is activated and the link between the activated value and attitude is activated as well. However, merely activating a specific value is not sufficient to instigate a significant change in the relationship between a value and its related attitudes.
