Sex Differences in Relationship Aggression Among Young Adults in Germany

The study examined the prevalence of physical aggression in the relationships of young adults in Germany. A convenience sample of 248 women and 400 men aged between 17 and 29 years provided reports of physical aggression shown toward and experienced by a partner using the revised Conflict Tactics Scales (CTS2). Sex differences were found for several physically aggressive behaviors measured by the CTS2, mostly for minor forms of physical aggression. All sex differences were in the direction of women scoring higher than men on the perpetration of aggressive acts, and men scoring higher than women on being the targets of partner aggression. The findings are discussed in the context of the current debate on sex differences in relationship aggression.     

Causal and moral responsibility: Antecedents and consequences of group‐based guilt

In six studies (N = 1045) conducted in three European countries, we demonstrate distinctions between causal responsibility, group‐based guilt, and moral responsibility. We propose that causal responsibility is an antecedent of group‐based guilt linking the ingroup to previous transgressions against the victim group. In contrast, moral responsibility is a consequence of group‐based guilt and is conceptualized as a sociomoral norm to respond to the consequences of the ingroup's transgressions and the current needs of the victim group. As such, moral responsibility can be stimulated by group‐based guilt and directly predicts individual action intentions. Studies 1 and 2 focus on the conceptual distinctions among the three constructs. Study 3 tests the indirect effect of causal responsibility on moral responsibility via group‐based guilt. The remaining studies explore the mediating role of moral responsibility in associations between group‐based guilt and compensatory action tendencies, that is, financial compensation (study 4), approach and avoidance tendencies (study 5) and public apology (study 6). Together these studies show that causal and moral responsibility are psychologically distinct concepts from group‐based guilt and that moral responsibility plays an important role in shaping the effects of group‐based guilt on behavioral intentions.

The Role of Friends’ Disruptive Behavior in the Development of Children’s Tobacco Experimentation: Results from a Preventive Intervention Study

Having friends who engage in disruptive behavior in childhood may be a risk factor for childhood tobacco experimentation. This study tested the role of friends’ disruptive behavior as a mediator of the effects of a classroom based intervention on children’s tobacco experimentation. 433 Children (52% males) were randomly assigned to the Good Behavior Game (GBG) intervention, a universal preventive intervention targeting disruptive behavior, and facilitating positive prosocial peer interactions. Friends’ disruptive behavior was assessed from age 7–10 years. Participants’ experimentation with tobacco was assessed annually from age 10–13. Reduced rates in tobacco experimentation and friends’ disruptive behavior were found among GBG children, as compared to controls. Support for friends’ disruptive behavior as a mediator in the link between intervention status and tobacco experimentation was found. These results remained after controlling for friends’ and parental smoking status, and child ADHD symptoms. The results support the role of friends’ disruptive behavior in preadolescents’ tobacco experimentation.     

A Simon effect with stationary moving stimuli

To clarify whether motion information per se has a separable influence on action control, the authors investigated whether irrelevant direction of motion of stimuli whose overall position was constant over time would affect manual left-right responses (i.e., reveal a motion-based Simon effect). In Experiments 1 and 2, significant Simon effects were obtained for sine-wave gratings moving in a stationary Gaussian window. In Experiment 3, a direction-based Simon effect with random-dot patterns was replicated, except that the perceived direction of motion was based on the displacement of single elements. Experiments 4 and 5 studied motion-based Simon effects to point-light figures that walked in place--displays requiring high-level analysis of global shape and local motion. Motion-based Simon effects occurred when the displays could be interpreted as an upright human walker, showing that a high-level representation of motion direction mediated the effects. Thus, the present study establishes links between high-level motion perception and action.     

The relationship between the inner and outer dimensions in Islam as a foundation for inter‐religious dialogue

This article shows how the relationship between the sharīa and the arīqa in Islam constitutes a specific paradigm for the bond between the interior and exterior dimension in religion, which enriches and challenges the Christian–Muslim dialogue for peace because it reminds both religions of their potential for critical social–political assessments. This is especially important since the public dialogue generally focuses on post‐Enlightenment criteria for evaluating the possibilities for communion in peace by strictly separating the interior from the exterior dimension in religion.     

Action induction through action observation

Ideomotor movements may arise in individuals while they watch goal-directed actions or events. In a previous study we developed a paradigm for investigating ideomotor movements induced through watching the outcome of one's own action. In the present study we extended the paradigm to investigate both movements induced through watching the outcome of one's own as well as somebody else's action (player mode and observer mode respectively). We report three experiments, each with differing conditions for the player mode, but identical conditions for the observer mode. Results indicate that in both modes ideomotor movements are governed by two basic principles: Perceptual induction and intentional induction. In the player mode we replicated and extended previous findings, indicating dissociation between hand and head movements. In the observer mode no such dissociation was obtained. Our findings suggest that people perform, in their own actions, what they see being performed in other people's actions. Induction of action through observation can pertain to both the action's physical surface and underlying intentions. Furthermore, our results suggest that perceptual induction is ubiquitous but may be locally suspended for intentional action control. We discuss our results in the framework of theories invoking a strong overlap between representational structures for action perception and action planning.     

Preschoolers' inhibition in their home: relation to temperament

Researchers assessed 58 preschoolers' reactions to an unfamiliar person and unfamiliar objects in their familiar home environment. Children participated in a 30-min procedure designed to elicit behavioral inhibition, including (a) a free-play period with a stranger present, (b) a structured interaction with the stranger, and (c) uncertainty-eliciting tasks. Behaviors representing the child's reactions toward the mother, stranger, and novel objects were coded. Mothers completed a temperament scale. Preschoolers exhibited behaviors indicative of inhibition toward unfamiliar social and nonsocial stimuli; behaviors remained stable across increasingly intrusive episodes. The approach/withdrawal component of temperament was related to behavioral inhibition. Individual differences in mood did not appear to be related to differences in inhibition. Parent reported temperament was related to researcher-observed behaviors.     

The brain generates its own sentence melody: a Gestalt phenomenon in speech perception

Brain processes underlying spoken language comprehension comprise auditory encoding, prosodic analysis and linguistic evaluation. Auditory encoding usually activates both hemispheres while language-specific stages are lateralized: analysis of prosodic cues are right-lateralized while linguistic evaluation is left-lateralized. Here, we investigated to what extent the absence of prosodic information influences lateralization. MEG brain-responses indicated that syntactic violations lead to early bi-lateral brain responses for syntax violations. When the pitch of sentences was flattened to diminish prosodic cues, the brain's syntax response was lateralized to the right hemisphere, indicating that the missing pitch was generated automatically by the brain when it was absent. This represents a Gestalt phenomenon, since we perceive more than is actually presented.
