Convergent and divergent responses to emotional displays of ingroup and outgroup

In the present research, we test the assumption that emotional mimicry and contagion are moderated by group membership. We report two studies using facial electromyography (EMG; Study 1), Facial Action Coding System (FACS; Study 2), and self-reported emotions (Study 2) as dependent measures. As predicted, both studies show that ingroup anger and fear displays were mimicked to a greater extent than outgroup displays of these emotions. The self-report data in Study 2 further showed specific divergent reactions to outgroup anger and fear displays. Outgroup anger evoked fear, and outgroup fear evoked aversion. Interestingly, mimicry increased liking for ingroup models but not for outgroup models. The findings are discussed in terms of the social functions of emotions in group contexts.

Motor imagery effectiveness for mirror reversed movements

Physical practice is known to enhance motor adaptation skills, which refer to the individual ability to compensate for environmental changes. So far, it is still unknown whether a similar effect can be observed following motor imagery (MI). Thirty-nine participants were tested during a joystick tracking task under both normal and mirror conditions (i.e., the inductive direction of the joystick was reversed), before and after a physical practice or MI training phase. Eye movements and electromyographic activity were recorded during MI. Motor performance was also evaluated after a 6 h interval during daytime. As compared to the control group, the results revealed that both MI and physical practice improved motor performance in the mirror condition, during the post-training test. Furthermore, the time to complete the task was further reduced after 6 hours, both in the normal and mirror conditions. These results demonstrate the effectiveness of MI for learning mirror-reversed movements, and for the consolidation process that follows motor adaptation.     

Challenges and Opportunities for Intervening with Couples in the Aftermath of the Global War on Terrorism

The unique culture of the military family in the early part of the twenty-first century will be examined, including the high operational tempo, frequent geographic moves, high rates of service among women, and the unique constellation of deployed troops from Active Duty, National Guard and Reserve components. Challenges faced by these couples are described, followed by key issues for clinicians to assess. Several developing couple-based interventions will be described, followed by a vignette which will highlight the issues and opportunities for these couples. In addition to reviewing common difficulties among military families, the authors will highlight strengths inherent to the military culture that clinicians can utilize in helping families develop resiliency.     

Inference making and linking both require thinking: Spontaneous trait inference and spontaneous trait transference both rely on working memory capacity

Past research suggests that spontaneous trait inference (STI) and spontaneous trait transference (STT) may reflect different cognitive processes, the former being inferential and the latter associational. The present research was designed to explore whether either or both of these processes involve thinking that occupies cognitive capacity. Four studies suggest that reductions in available cognitive capacity reduce both STI and STT effects, both on measures of savings in relearning (which reflect the strength of trait associations with a person) and on trait ratings measures (which reflect the strength of trait inferences made about a person). Similar results were obtained using an individual difference measure of cognitive capacity. Although these results suggest that STI and STT are similar, in that both exhibit interference from reductions in cognitive capacity, other results, such as halo effects in trait ratings, support previous assertions that their underlying processes are distinct.     

Waking and dreaming: related but structurally independent. Dream reports of congenitally paraplegic and deaf-mute persons

Models of dream analysis either assume a continuum of waking and dreaming or the existence of two dissociated realities. Both approaches rely on different methodology. Whereas continuity models are based on content analysis, discontinuity models use a structural approach. In our study, we applied both methods to test specific hypotheses about continuity or discontinuity. We contrasted dream reports of congenitally deaf-mute and congenitally paraplegic individuals with those of non-handicapped controls. Continuity theory would predict that either the deficit itself or compensatory experiences would surface in the dream narrative. We found that dream form and content of sensorially limited persons was indifferent from those of non-handicapped controls. Surprisingly, perceptual representations, even of modalities not experienced during waking, were quite common in the dream reports of our handicapped subjects. Results are discussed with respect to feedforward mechanisms and protoconsciousness theory of dreaming.     

Sensori-motor spatial training of number magnitude representation

An adequately developed spatial representation of number magnitude is associated with children's general arithmetic achievement. Therefore, a new spatial-numerical training program for kindergarten children was developed in which presentation and response were associated with a congruent spatial numerical representation. In particular, children responded by a full-body spatial movement on a digital dance mat in a magnitude comparison task. This spatial-numerical training was more effective than a non-spatial control training in enhancing children's performance on a number line estimation task and a subtest of a standardized mathematical achievement battery (TEDI-MATH). A mediation analysis suggested that these improvements were driven by an improvement of children's mental number line representation and not only by unspecific factors such as attention or motivation. These results suggest a benefit of spatial numerical associations. Rather than being a merely associated covariate, they work as an independently manipulated variable which is functional for numerical development.     

The perception of changing emotion expressions

The utility of recognising emotion expressions for coordinating social interactions is well documented, but less is known about how continuously changing emotion displays are perceived. The nonlinear dynamic systems view of emotions suggests that mixed emotion expressions in the middle of displays of changing expressions may be decoded differently depending on the expression origin. Hysteresis is when an impression (e.g., disgust) persists well after changes in facial expressions that favour an alternative impression (e.g., anger). In expression changes based on photographs (Study 1) and avatar images (Studies 2a-c, 3), we found hystereses particularly in changes between emotions that are perceptually similar (e.g., anger-disgust). We also consistently found uncertainty (neither emotion contributing to the mixed expression was perceived), which was more prevalent in expression sequences than in static images. Uncertainty occurred particularly in changes between emotions that are perceptually dissimilar, such as changes between happiness and negative emotions. This suggests that the perceptual similarity of emotion expressions may determine the extent to which hysteresis and uncertainty occur. Both hysteresis and uncertainty effects support our premise that emotion decoding is state dependent, a characteristic of dynamic systems. We propose avenues to test possible underlying mechanisms.     

Forgiveness and Cohesion in Familial Perceptions of Alcohol Misuse

The authors examine the relationships between forgiveness, family cohesion, and alcohol. In Study 1 (N= 190), participants reported lower levels of trust and forgiveness for family members who misuse alcohol. In Study 2 (N= 141), the authors present a model demonstrating family cohesion and trait forgiveness related to state forgiveness of an alcohol‐misusing family member. State forgiveness was related to trust in that family member and, subsequently, higher levels of perceived misuser drinking refusal efficacy.
