AN EXPRESSIVE WRITING INTERVENTION TO COPE WITH LESBIAN-RELATED STRESS: THE MODERATING EFFECTS OF OPENNESS ABOUT SEXUAL ORIENTATION

Over the past two decades, expressive writing interventions have been used successfully to reduce distress and improve well-being for those dealing with traumatic events, stressors, and illnesses. The purpose of this study was to investigate an expressive writing intervention for lesbian-related stressors. As expected, writing about traumatic events related to sexual orientation reduced self-reported confusion and perceived stress over a 2-month period for those lesbians who were less open about their sexual orientation. Interestingly, writing about such traumatic experiences was associated with increases in confusion and perceived stress for those who were more open about their sexual orientation. Applying this paradigm to assist individuals in coping with stressors related to their sexual orientation represents an important addition to the expressive writing literature. Furthermore, it offers a promising, cost-effective method to assist closeted lesbians in coping with stressors related to their sexual orientation.     

One but not the same: Evaluative conditioning with mixed-valence USs

In evaluative conditioning (EC), the pairing of a positively or negatively valenced stimulus (US) with another neutral stimulus (CS) leads to a corresponding change in liking of the CS. EC research so far has concentrated on using unambiguously positive or negative USs. However, attitude objects often possess multiple features that can be positive and negative at the same time. The present research addresses the question of how EC is affected by using such mixed-valence stimuli as USs. In two studies, USs of mixed valence (i.e., positive behavior and membership in a negative group or vice versa) were paired with affectively neutral CSs. Interestingly, results showed that the mixed-valence USs were evaluated according to the valence of the behavioral information. In contrast, the evaluation of associated CSs was more strongly influenced by the valence of the group information that was presented about the USs. Possible explanations as well as implications for EC research are discussed.     

Reactance,the self,and its group: When threats to freedom come from the ingroup versus the outgroup

We investigated the assumption that independent versus interdependent self‐construals yield different manifestations of psychological reactance in different group contexts. We expected collectivists (interdependent) to value the collective freedom of an ingroup more in face of an outgroup threat than individualists (independent) who should be protective of their individual freedom especially within an ingroup. In Study 1, we showed that collectivists (Taiwanese students) did not show reactance when a threat to their freedom of choice originated in the ingroup, but they did show reactance when it originated in an outgroup. In Study 2, Austrian students showed more reactance the more interdependent their self‐construal was when confronted with an outgroup restriction. However, the more independent Austrian students' self‐construal was, the more reactance they showed when the threat came from the ingroup. Priming an independent (versus interdependent) self‐construal in Study 3, we again observed more reactance when freedom was restricted by the ingroup. The findings underline the importance of understanding psychological reactance as a socially situated phenomenon. Copyright © 2011 John Wiley & Sons, Ltd.     

Movement pattern recognition in basketball free-throw shooting

The purpose of the present study was to analyze the movement patterns of free-throw shooters in basketball at different skill levels. There were two points of interest. First, to explore what information can be drawn from the movement pattern and second, to examine the methodological possibilities of pattern analysis. To this end, several qualitative and quantitative methods were employed. The resulting data were converged in a triangulation. Using a special kind of ANN named Dynamically Controlled Networks (DyCoN), a 'complex feature' consisting of several isolated features (angle displacements and velocities of the articulations of the kinematic chain) was calculated. This 'complex feature' was displayed by a trajectory combining several neurons of the network, reflecting the devolution of the twelve angle measures over the time course of each shooting action. In further network analyses individual characteristics were detected, as well as movement phases. Throwing patterns were successfully classified and the stability and variability of the realized pattern were established. The movement patterns found were clearly individually shaped as well as formed by the skill level. The triangulation confirmed the individual movement organizations. Finally, a high stability of the network methods was documented.     

Decrease of prefrontal-posterior EEG coherence: loose control during social-emotional stimulation

In two experiments we aimed to investigate if individual differences in state-dependent decreases or increases of EEG coherence between prefrontal and posterior cortical regions may be indicative of a mechanism modulating the impact social-emotional information has on an individual. Two independent samples were exposed to an emotional stimulation paradigm in which the participants were invited to get involved and sympathize with the persons they were watching (study 1) or listening to (study 2), and who were expressing sadness or anxiety. The two studies yielded consistent results. Higher scores in trait absorption and in the propensity to ruminate were associated with decreased EEG beta coherence during the stimulation, whereas coherence increased in individuals low in absorption or rumination. Coherence changes did not predict to which degree the participants felt infected by the displayed emotions, but in individuals showing decreased prefrontal-posterior coupling during the stimulation, feelings of sadness and anxiety had a greater tendency to persist. The findings suggest that more loose prefrontal-posterior coupling may be related to loosening of control of the prefrontal cortex over incoming social-emotional information and, consequently, to deeper emotional involvement and absorption, whereas increased prefrontal-posterior coupling may be related to strong control, dampening of emotional experience, and not letting oneself become emotionally affected.     

Terrorists and victims. Infrahumanization of Moroccans after 11-M

Infrahumanization studies have verified that most people attribute more secondary emotions to the ingroup than to the outgroup. However, these results may vary with changing contexts. The main objective of this study was to investigate the infrahumanization of Moroccans, depending on the context, after the 11-M attacks and seven years later. For this purpose, variations that occur in the allocation of essential human qualities--secondary emotions--were analyzed by activating images of outgroup members in two opposite contexts: Guilty of the terrorist attack or its victim. The results show that the infrahumanization of the Moroccans in the perpetrator context does not change significantly with regard to the control group. However, infrahumanization does not take place when Moroccans are associated with a victim context, though only immediately after the terrorist attack, because seven years later, this effect disappears.
