Depressive thoughts limit working memory capacity in dysphoria

Dysphoria is associated with persistence of attention on mood-congruent information. Longer time attending to mood-congruent information for dysphoric individuals (DIs) detracts from goal-relevant information processing and should reduce working memory (WM) capacity. Study 1 showed that DIs and non-DIs have similar WM capacities. Study 2 embedded depressive information into a WM task. Compared to non-DIs, DIs showed significantly reduced WM capacity for goal-relevant information in this task. Study 3 replicated results from Studies 1 and 2, and further showed that DIs had a significantly greater association between processing speed and recall on the depressively modified WM task compared to non-DIs. The presence of inter-task depressive information leads to DI-related decreased WM capacity. Results suggest dysphoria-related WM capacity deficits when depressive thoughts are present. WM capacity deficits in the presence of depressive thoughts are a plausible mechanism to explain day-to-day memory and concentration difficulties associated with depressed mood.     

The intergenerational transmission of empathy-related responding in adolescence: the role of maternal support

This study proposed and tested an integrated model of the intergenerational transmission of empathy-related responding in adolescence. This model included maternal support as a mediator of the intergenerational transmission of empathy and examined friendship quality as an outcome of adolescent empathy. In a sample of middle adolescents and their mothers (N = 177), maternal support significantly predicted the empathy dimensions perspective taking and sympathy and mediated the mother-child concordance of perspective taking but not sympathy. Adolescent empathy (and perspective taking in particular) predicted adolescent friendship quality and served as an intervening variable in the relation between maternal support and friendship quality. Implications of the present study for research on the socialization of empathy-related responding and social adjustment in general are outlined.     

Parental psychological control and dimensions of identity formation in emerging adulthood.

Longitudinal data were used to evaluate whether parental psychological control would have a negative impact on identity formation. Perceived psychological control and 4 identity dimensions (i.e., commitment making, exploration in breadth, identification with commitment, and exploration in depth) were assessed 5 times in a college sample. Associations between psychological control and identity (i.e., negative associations with both commitment dimensions and a positive association with exploration in breadth) were stable across time. Further, the developmental pathways of these constructs appeared to be correlated: Increases in psychological control were associated with simultaneous decreases in both commitment dimensions. Finally, reciprocal effects were found: Psychological control inhibited progress in both commitment dimensions, whereas exploration in breadth led to increased psychological control. The authors have provided suggestions for helping emerging adults to approach the task of identity formation.     

Authoritarianism and Social Dominance in Western and Eastern Europe: The Importance of the Sociopolitical Context and of Political Interest and Involvement

The present study tests whether the magnitude of the relation between Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) is stable across and within cultures, whether their differential relations with value orientations and sociopolitical attitudes remain stable in spite of these possible differences, and whether their differential relations point to a different genesis. For these purposes, two student samples (total N = 684), three adult samples (total N = 553), and a political activist sample (N = 69) were gathered in Belgium, and one adult sample (N = 235) was collected in Poland. Both cross- and intracultural differences in the strength of the RWA-SDO relation emerged. These can be attributed to specificities in sociopolitical context and differences in political socialization, interest, and involvement. In spite of these fluctuations, in the strength of the RWA-SDO relation, regression analyses revealed high stability of the relation between RWA-SDO and sociopolitical attitudes, and mediation analyses supported the hypothesis of their different genesis.     

Vagueness-Adaptive Logic: A Pragmatical Approach to Sorites Paradoxes

Kripke-completeness of every classical modal logic with Sahlqvist formulas is one of the basic general results on completeness of classical modal logics. This paper shows a Sahlqvist theorem for modal logic over the relevant logic Bin terms of Routley-Meyer semantics. It is shown that usual Sahlqvist theorem for classical modal logics can be obtained as a special case of our theorem.     

The Role of Separation Anxiety in Mothers’ Use of Autonomy Support: An Observational Study

Parental separation anxiety has been identified as a detrimental factor for parent-adolescent relationship quality and, ultimately, for adolescents’ psychosocial adjustment. However, few studies have examined how separation anxiety is related to parents’ style of interaction with their adolescent, which is unfortunate as this interaction style could explain why separation anxiety is related to negative outcomes. The present study (a) examined the association between maternal separation anxiety and mothers’ autonomy-supportive, relative to controlling, conversation style as observed in mother-adolescent interactions about the adolescents’ friendships, and (b) investigated the link between maternal separation anxiety and mothers’ personal experiences during the conversation. A total of 62 mother–adolescent dyads (M age mothers?=?44 years, M age adolescents?=?14 years) were willing to participate in this study. After mothers filled out a measure of separation anxiety, mothers’ autonomy-supportive and controlling practices were observed and coded during a 10-min conversation. Further, mothers reported on their emotional and motivational experiences during the conversation. Mothers high on separation anxiety were observed to be less autonomy-supportive and to experience the conversation as more stressful (e.g., more pressure, more tension, and more relief at the end). Clinically, our results suggest that maternal separation anxiety is an important target for intervention and prevention efforts aimed at promoting autonomy-supportive parenting.     

Exercise training can improve spatial characteristics of time-critical obstacle avoidance in elderly people

Fall prevention programs have rarely been evaluated by quantitative movement analysis methods. Quantitative movement analyses could provide insight into the mechanisms underlying the effects of training. A treadmill obstacle avoidance task under time pressure has recently been used to evaluate a fall prevention exercise program for community-dwelling elderly people and it showed that participants improved their obstacle avoidance success rates. The mechanism, by which the increased success rates were achieved, however, remained to be determined. Participants were elderly who had fallen at least once in the year prior to participation. They were assigned to either the exercise or the control group. The control group did not receive any specific treatment. The exercise group was administered a five week exercise program, which consisted of exercises on a functionally oriented obstacle course, walking exercises, and practice of fall techniques. Pre- and post-intervention laboratory obstacle avoidance tests were conducted. Three possible determinants of success were investigated, namely avoidance reaction times, the distribution of avoidance strategies, and three spatial parameters (toe distance, foot clearance and heel distance). Analysis yielded significant TimexGroup interactions in heel distances. The exercise group increased heel distance, while the control group did not. Increased heel distance may result in reduced risk of heel contact with the obstacle and, consequently, larger success rates. The remaining parameters showed no effect of training. In conclusion, the training program was effective in improving time-critical obstacle avoidance skills. In every day life, these effects of training may contribute to less obstacle-related fall incidents in elderly. In addition, these findings could indicate that the execution of other time-critical events, like an actual fall, could also be improved by training.     

Factors associated with experts' opinions regarding criminal responsibility in The Netherlands

In many jurisdictions, offenders need to have freely chosen to commit their crimes in order to be punishable. A mental defect or disorder may be a reason for diminished or total absence of criminal responsibility and may remove culpability. This study aims to provide an empirically based understanding of the factors on which experts base their judgements concerning criminal responsibility. Clinical, demographic and crime related variables, as well as MMPI-2 profiles, were collected from final reports concerning defendants of serious crime submitted to the observation clinic of the Dutch Ministry of Justice for a criminal responsibility assessment. Criminal responsibility was expressed along a five-point scale corresponding to the Dutch legal practice. Results showed that several variables contributed independently to experts' opinions regarding criminal responsibility: diagnosis (Axis I and II), cultural background, type of weapon used in committing the crime, and whether the defendant committed the crime alone or with others. In contract to jurisdictions involving a sane/insane dichotomy, the Dutch five-point scale of criminal responsibility revealed that Axis II personality disorders turned out to be mostly associated with a diminished responsibility. MMPI-2 scores also turned out to have a small contribution to experts' opinions on criminal responsibility, independently of mere diagnostic variables. These results suggest that experts base their judgements not only on the presence or absence of mental disorders, but also on cultural and crime related characteristics, as well as dimensional information about the defendant's personality and symptomatology.     

Offside decisions by expert assistant referees in association football: Perception and recall of spatial positions in complex dynamic events

This study investigated the offside decision-making process in association football. The first aim was to capture the specific offside decision-making skills in complex dynamic events. Second, we analyzed the type of errors to investigate the factors leading to incorrect decisions. Fédération Internationale de Football Association (FIFA; n = 29) and Belgian elite (n = 28) assistant referees (ARs) assessed 64 computer-based offside situations. First, an expertise effect was found. The FIFA ARs assessed the trials more accurately than the Belgian ARs (76.4% vs. 67.5%). Second, regarding the type of error, all ARs clearly tended to raise their flag in doubtful situations. This observation could be explained by a perceptual bias associated with the flash-lag effect. Specifically, attackers were perceived ahead of their actual positions, and this tendency was stronger for the Belgian than for the FIFA ARs (11.0 vs. 8.4 pixels), in particular when the difficulty of the trials increased. Further experimentation is needed to examine whether video- and computer-based decision-making training is effective in improving the decision-making skills of ARs during the game.
