Intolerance of "Others" among Palestinian and Jewish Students in Israel

This study analyzes intolerance against diverse sociopolitical groups and compares the social and political attitudes of two distinct and highly differentiated groups: Jewish and Palestinian high-school students in Israel. It examines their perceptions of the political context that structurates their "reality," and aims to find the factors that influence the extremity of their intolerance. The proposed model is more applicable to Jewish students than it is to Palestinians and shows that intolerance toward out-groups is influenced by religiosity, the salience of national and civic identity, national security issues, and political ideology.     

Differentiation of Self and the Process of Forgiveness: A Clinical Perspective for Couple and Family Therapy

In this article we explore the role of differentiation of self in facilitating forgiveness in the context of couple and family relationships. Differentiation is defined from the Bowen perspective as the ability to connect with others without being excessively emotionally reactive to the ebb and flow inherent in all significant relationships (being able to connect to others yet also being able to self‐regulate). Forgiveness is described as the releasing of an emotional injury via a complex psychological and relational process that is less an act of will than a discovery or possibility through understanding and empathy. Differentiation of self is related to emotional intelligence and empathy. The developmental and relational benefits of such are illustrated and discussed. A rationale for viewing differentiation and forgiveness in a contextual, historical, and relational attachment paradigm is suggested. Relevant clinical cases illustrate the dynamics of differentiation and forgiveness as discovery in the context of an understanding and empathic relational environment.     

Expressing Induced Emotions Through Free Dance Movement

The aim of this study was to examine the effect of two basic emotions, happiness and sadness, on dance movement. A total of 32 adult participants were induced to feel emotional states of either happiness or sadness and then danced intuitively to an emotionally ‘neutral’ piece of music, composed specifically for the experiment. Based on an Effort-Shape analysis of body movement, full body movement was captured and seven different movement cues were examined, in order to explore whether differences in corporeal articulations between the happy and sad condition existed. Results revealed that in the happy condition, participants moved faster, with more acceleration, and made more expanded and more impulsive movements than in the sad condition. Results are discussed with respect to possible consequences for future research on human movement.     

Mental Rotation of Dynamic,Three‐Dimensional Stimuli by 3‐Month‐Old Infants

Mental rotation involves transforming a mental image of an object so as to accurately predict how the object would look if it were rotated in space. This study examined mental rotation in male and female 3‐month‐olds, using the stimuli and paradigm developed by Moore and Johnson (2008) . Infants were habituated to a video of a three‐dimensional object rotating back and forth through a 240° angle around the vertical axis. After habituation, infants were tested both with videos of the same object rotating through the previously unseen 120° angle, and with the mirror image of that display. Unlike females, who fixated the test displays for approximately equal durations, males spent significantly more time fixating the familiar object than the mirror‐image object. Because familiarity preferences like this emerge when infants are relatively slow to process a habituation stimulus, the data support the interpretation that mental rotation of dynamic three‐dimensional stimuli is relatively difficult—but possible—for 3‐month‐old males. Interpretation of the sex differences observed in 3‐ and 5‐month‐olds’ performances is discussed.     

Is Poker a Game of Skill or Chance? A Quasi-Experimental Study

Due to intensive marketing and the rapid growth of online gambling, poker currently enjoys great popularity among large sections of the population. Although poker is legally a game of chance in most countries, some (particularly operators of private poker web sites) argue that it should be regarded as a game of skill or sport because the outcome of the game primarily depends on individual aptitude and skill. The available findings indicate that skill plays a meaningful role; however, serious methodological weaknesses and the absence of reliable information regarding the relative importance of chance and skill considerably limit the validity of extant research. Adopting a quasi-experimental approach, the present study examined the extent to which the influence of poker playing skill was more important than card distribution. Three average players and three experts sat down at a six-player table and played 60 computer-based hands of the poker variant “Texas Hold’em” for money. In each hand, one of the average players and one expert received (a) better-than-average cards (winner’s box), (b) average cards (neutral box) and (c) worse-than-average cards (loser’s box). The standardized manipulation of the card distribution controlled the factor of chance to determine differences in performance between the average and expert groups. Overall, 150 individuals participated in a “fixed-limit” game variant, and 150 individuals participated in a “no-limit” game variant. ANOVA results showed that experts did not outperform average players in terms of final cash balance. Rather, card distribution was the decisive factor for successful poker playing. However, expert players were better able to minimize losses when confronted with disadvantageous conditions (i.e., worse-than-average cards). No significant differences were observed between the game variants. Furthermore, supplementary analyses confirm differential game-related actions dependent on the card distribution, player status, and game variant. In conclusion, the study findings indicate that poker should be regarded as a game of chance, at least under certain basic conditions, and suggest new directions for further research.     

The Continued Importance of Quality Parent–Adolescent Relationships During Late Adolescence

The quality of adolescents' relationships with residential parents has been found to predict many different health and behavioral youth outcomes; strong associations have also been found between these outcomes and family processes, and between relationship quality and family processes. Data from Rounds 1–5 of the National Longitudinal Survey of Youth, 1997 were used to examine hypotheses about the influence of the parent–adolescent relationship on subsequent adolescent mental well‐being and delinquency, as mediated by family processes. Using structural equation modeling, we found that the influence of a positive residential parent–adolescent relationship on better mental well‐being and fewer delinquency was entirely mediated by family routines, parental monitoring, and parental supportiveness, net of sociodemographic controls.     

A Longitudinal Study of Depressive Symptoms and Marijuana Use in a Sample of Inner‐City African Americans

The association between marijuana use and depressive symptoms was examined longitudinally in a sample of 622 African American youth, interviewed on six occasions, using hierarchical linear modeling (HLM). We considered whether depressive symptoms predicted changes in marijuana use and vice versa from high school through the transition into young adulthood. We also examined gender differences in these behaviors over time. The results indicated that depressive symptoms predicted later marijuana use only for males. Marijuana use did not predict later depressive symptoms for females or males. These findings are consistent with a unidirectional hypothesis indicating that marijuana use may play a role as mood regulator among young males, but not among females. Research findings also indicate that females with lower depressive symptoms use more marijuana than females who report high depressive symptoms. These findings did not change even after controlling for the effects of using other substances at previous stages, school achievement, and demographics factors. These results suggest that depressive symptoms may be an antecedent of marijuana use among African American males.     

A decision support system for the graph model of conflicts

A comprehensive decision support system called GMCA (Graph Model for Conflict Analysis) implementing the multi-player graph model for analyzing conflicts is developed. GMCA contains algorithms for the rapid computation of a wide range of solution concepts, thereby enabling decision makers to take account of the diversity of human behavior. Using an engineering case study, the key features of GMCA are illustrated.
