Who Benefits from Couple Relationship Education? Findings from the Largest German CRE Study

In evaluation studies on couple relationship enhancement (CRE) programs, researchers are encouraged to also investigate which couples benefit from program participation. The authors qualified 104 university students to offer an evidence-based CRE program. Up to a 15-month follow-up, the participating couples (N = 234) reported a significant decrease in unsolved relationship conflicts. A 2-day-long intensive training led to better results compared with a weekly format regarding dropouts. Couples with lower pretest satisfaction ratings reported significant improvements over time, whereas couples with initial higher ratings reported no change or a deterioration. Further predictors were identified. The findings should be taken into account in future research.     

Dispositional empathy and the hierarchical structure of personality

Personality psychology has recognized a fundamental 5-factor structure that has integrated and organized theory and research. Nevertheless, personality-like differences beyond that structure have been identified. In heretofore unrelated research, dispositional empathy has been an essential construct in understanding human development, behavior, and interpersonal relationships. Addressing a gap in the literature, we map multidimensional dispositional empathy into 2 versions of the 5-factor space. Empathic concern is closely related to agreeableness, and personal distress is closely related to neuroticism. Perspective taking has complex, interstitial relationships with the 5 factors. In contrast, fantasy is not well explained by the 5 factors. We discuss the implications of these findings for understanding dispositional empathy and for understanding the 5-factor structure, its correlates in emotional processes and experiences, and its limits.     

Examining the association between MAOA genotype and incarceration, anger and hostility: The moderating influences of risk and protective factors

Findings from molecular genetic research have indicated that a polymorphism in the promoter region of the MAOA gene interacts with environmental liabilities to predict antisocial phenotypes. We use these findings as a springboard to examine whether a global protective-risk factor index moderates the effect of MAOA genotype on the probability of being incarcerated and on a measure of anger and hostility. Analysis of data from the National Longitudinal Study of Adolescent Health (Add Health) indicates that exposure to risk and protective factors in adolescence are able to moderate the effect of MAOA genotype on anger and hostility in adulthood for males. The results in relation to the probability of being incarcerated were consistently null.     

Social inclusion facilitates risky mating behavior in men

Although past research has reliably established unique effects of social exclusion on human cognition and behavior, the current research focuses on the unique effects of social inclusion. Recent evidence indicates that social inclusion leads to enhanced prioritization of reproductive interests. The current study extends these findings by showing that the pursuit of these inclusion-induced reproductive goals occurs in sex-specific ways. Across three experiments, social inclusion led men, but not women, to endorse riskier, more aggressive mating strategies compared to control and socially excluded participants. Specifically, included men were more likely to endorse sexual aggression (Experiment 1), high-risk mate poaching behaviors (Experiment 2), and high-risk mate retention tactics (Experiment 3). These results demonstrate that the experience of social inclusion can affect sex-differentiated preferences for risky mating strategies.     

When under threat,we all look the same: Distinctiveness threat induces ingroup homogeneity in face memory

The current research investigated the well-established outgroup homogeneity effect in face memory (worse recognition for outgroup faces than ingroup faces). Because past research has shown that group distinctiveness threat can enhance ingroup homogeneity, of interest in the current research was whether distinctiveness threat affects face recognition. Across two studies, we found that threatening White American participants’ ethnic distinctiveness led to a reduction in same-race face recognition. In other words, distinctiveness threat created ingroup homogeneity in face memory. In both studies, distinctiveness threat led Whites’ same-race recognition to drop to cross-race levels. Implications were discussed in terms of how the structure of intergroup relations may drive intergroup differences in face memory.     

Three Arguments For Scientific Freedom

The principle of scientific freedom is usually taken forgranted; few attempts have been made to justify it systematically. The present paper discusses three “classic” arguments, which are used to justify this principle. However, it will become clear that (a) each argument refers to a different understanding of science and therefore justifies a different type of science, and that (b) each of them is based on assumptions which are not always consistent with the social reality of scientific research; the profound changes science has undergone since its inception are not sufficiently taken into account.     

Perisaccadic parietal and occipital gamma power in light and in complete darkness

Our objective was to determine perisaccadic gamma range oscillations in the EEG during voluntary saccades in humans. We evaluated occipital perisaccadic gamma activity both in the presence and absence of visual input, when the observer was blindfolded. We quantified gamma power in the time periods before, during, and after horizontal saccades. The corresponding EEG was evaluated for individual saccades and the wavelet transformed EEG averaged for each time window, without averaging the EEG first. We found that, in both dark and light, parietal and occipital gamma power increased during the saccade and peaked prior to reaching new fixation. We show that this is not the result of muscle activity and not the result of visual input during saccades. Saccade direction affects the laterality of gamma power over posterior electrodes. Gamma power recorded over the posterior scalp increases during a saccade. The phasic modulation of gamma by saccades in darkness--when occipital activity is decoupled from visual input--provides electrophysiological evidence that voluntary saccades affect ongoing EEG. We suggest that saccade-phasic gamma modulation may contribute to short-term plasticity required to realign the visual space to the intended fixation point of a saccade and provides a mechanism for neuronal assembly formation prior to achieving the intended saccadic goal. The wavelet-transformed perisaccadic EEG could provide an electrophysiological tool applicable in humans for the purpose of fine analysis and potential separation of stages of 'planning' and 'action'.     

The effects of sequence difficulty and practice on proportional and nonproportional transfer

Two experiments were designed to determine participants' ability to transfer a learned movement sequence to new spatial locations. A 16-element dynamic arm movement sequence was used in both experiments. The task required participants to move a horizontal lever to sequentially projected targets. Experiment 1 included two groups. One group practised a relatively easy 16-element movement sequence (easy long). The other group practised a more difficult 16-element movement sequence (difficult long). Approximately 24 hours after practice with their respective sequence both groups were administered a retention and two transfer tests. The only difference between the retention and transfer tests was the location of the targets. The short transfer target configuration was considered a proportional transfer because all the amplitudes between targets were reduced by the same proportion. The mixed transfer configuration was considered a nonproportional transfer because the targets did not have the same proportional distances between targets as the sequence they practised. The results indicated that participants could effectively transfer the difficult long sequence to the new target configurations regardless of whether the transfer required proportional and nonproportional spatial changes to the movement pattern. However, the easy long sequence was only effectively transferred in the proportional transfer condition. Experiment 2 assessed the effects of extended practice of the easy long sequence on proportional and nonproportional spatial transfer. The data indicated that participants could again effectively transfer the easy long sequence to proportional but not the nonproportional spatial transfer conditions regardless of the amount of practice (1 or 4 days). The results are discussed in terms of the mechanism by which response sequences become increasingly specific over extended practice in an attempt to optimize movement production and how this process interacts with the difficulty of the sequence.
