Oxytocin Receptor (OXTR) Single Nucleotide Polymorphisms Indirectly Predict Prosocial Behavior Through Perspective Taking and Empathic Concern

Engaging in prosocial behavior can provide positive outcomes for self and others. Prosocial tendencies contribute to the propensity to engage in prosocial behavior. The oxytocin receptor gene (OXTR) has also been associated with prosocial tendencies and behaviors. There has been little research, however, investigating whether the relationship between OXTR and prosocial behaviors is mediated by prosocial tendencies. This relationship may also vary among different types of prosocial behavior. The current study examines the relationship between OXTR, gender, prosocial tendencies, and both altruistic and public prosocial behavior endorsement. Students at a midwestern university (N = 398; 89.2% Caucasian; M_age = 20.76; 26.6% male) provided self‐report measures of prosocial tendencies and behaviors and buccal cells for genotyping OXTR polymorphisms. Results indicated that OXTR single nucleotide polymorphism (SNP) rs2268498 genotype significantly predicted empathic concern, whereas gender moderated the association between several other OXTR SNPs and prosocial tendencies. Increased prosocial tendencies predicted increased altruistic prosocial behavior endorsement and decreased public prosocial behavior endorsement. Our findings suggest an association between genetic variation in OXTR and endorsement of prosocial behavior indirectly through prosocial tendencies, and that the pathway is dependent on the type of prosocial behavior and gender.     

It’s About Time: The Role of Locomotion in Withdrawal Behavior

Introduction

Locomotion is defined as a self-regulatory orientation that involves committing personal resources to initiate and maintain goal-directed activities Kruglanski et al. (J Personal Social Psychol 79: 793, 2000). This article examines the relation between locomotion and withdrawal behaviors in organizational setting.

Materials and Methods

In the first study, police officers’ (N = 203) locomotion was negatively related to self-report measures of absenteeism and lateness. In the second study, bank employees’ (N = 297) locomotion was negatively related to withdrawal behaviors as evinced by organizational records including hours of absenteeism, lateness, and early departures. In the third study, a two-wave research design replicated the results of Study 2 by demonstrating that telecommunication employees’ (N = 69) locomotion measured at Time 1 was negatively related to their respective withdrawal behaviors 3 months later at Time 2.

Conclusion

Overall, these three studies support the notion that locomotion impacts a plurality of withdrawal behaviors in different organizational settings. Consequently, locomotion can be a pertinent and valuable psychometric tool for managers and human resources interested in improving organizational effectiveness.

     

Color search and visual field segregation

Visual search for targets that combine color and shape features that are shared by distracting items can be conducted spatially in parallel. Experimental results show that parallel search for color/shape conjunctions is possible when the shapes chosen let observers segregate the spatially interspersed items into figure and ground and when, within the figure, the target differs from other items by a distinguishing color feature. Results of experiments that manipulate stimulus color suggest that adaptive mechanisms of color discrimination are used to detect targets within such a figure.     

Attention shifts produce spatial stimulus codes

Summary In the Simon task the spatial position of the stimulus, though task irrelevant, influences speed of response. We (Umiltà & Nicoletti, 1992) proposed that the orienting of attention to the imperative stimulus produces a Stroop-like interference. This paper reports the results of three experiments that provide empirical support for two predictions of this hypothesis. One is that the stimulus spatial code is formed with relation to the position to which attention is directed. The other prediction is that the Simon effect is obtained on condition that attention can orient to the stimulus.Some of the results of Experiments 1 and 2 were reported briefly in Umiltà and Nicoletti (1992)     

The interplay of community and family risk and protective factors on adjustment in young adult immigrants

We examined the direct and interactive effects of community violence and both family cohesion and conflict on collective efficacy and aggressive behaviours among immigrant young adults. Participants included 221 young adults (ages 18–26; mean age = 21.36; 45.7% female, 190 born outside the U.S.) who completed self-report measures of their exposure to neighbourhood violence, social cohesion, collective efficacy and prosocial behaviours toward friends and strangers. Results, in general, showed that community violence and family cohesion were positively associated with collective efficacy whereas community violence and family conflict were positively associated with aggressive behaviours. Family cohesion and conflict also moderated the links between community violence and aggressive behaviours. Discussion focuses on the interplay of community and family processes and the relations to adjustment of immigrant young adults.     

Parental bonding and personality disorder: the mediating role of alexithymia

This study explored whether alexithymic features mediate the effect of perceived adverse parenting during childhood on being diagnosed with a PD in adulthood. Two hundred sixty-five psychiatric outpatients were evaluated with the Toronto Alexithymia Scale (TAS-20), the Parental Bonding Instrument (PBI), the Structured Interview for DSM-IV Personality, the Structured Clinical Interview for DSM-IV Axis I Disorders, the Clinical Global Impression scale, and the Global Assessment of Functioning scale. The statistical model for mediation proposed by Baron and Kenny (1986) was employed to detect whether the TAS scores account for the relation between PBI scores and a PD diagnosis. The results indicated that although altered parental bonding (and specifically, excessive maternal protection) may enhance the risk of PD, its effect is completely mediated by the alexithymic feature Difficulty Describing Feelings to Others (DDF), after controlling for gender, age, educational level, type, severity and age of onset of Axis I disorders. Therefore, this study suggests that the presence of DDF accounts for the effect of maternal overprotection as a risk factor for PD.     

How grammar can cope with limited short-term memory: simultaneity and seriality in sign languages

It is known that in American Sign Language (ASL) span is shorter than in English, but this discrepancy has never been systematically investigated using other pairs of signed and spoken languages. This finding is at odds with results showing that short-term memory (STM) for signs has an internal organization similar to STM for words. Moreover, some methodological questions remain open. Thus, we measured span of deaf and matched hearing participants for Italian Sign Language (LIS) and Italian, respectively, controlling for all the possible variables that might be responsible for the discrepancy: yet, a difference in span between deaf signers and hearing speakers was found. However, the advantage of hearing subjects was removed in a visuo-spatial STM task. We attribute the source of the lower span to the internal structure of signs: indeed, unlike English (or Italian) words, signs contain both simultaneous and sequential components. Nonetheless, sign languages are fully-fledged grammatical systems, probably because the overall architecture of the grammar of signed languages reduces the STM load. Our hypothesis is that the faculty of language is dependent on STM, being however flexible enough to develop even in a relatively hostile environment.     

Assessing regulatory emotional self-efficacy in three countries

The Regulatory Emotional Self-Efficacy (RESE) scale was developed to assess perceived self-efficacy in managing negative (NEG) and in expressing positive (POS) affect (G. V. Caprara & M. Gerbino, 2001). In this study of young adults, the factorial structure of the RESE scale was found to be similar in Italy, the United States, and Bolivia. In addition to a factor for POS, NEG was represented by a second-order factor of 2 different negative affects: despondency-distress (DES) and anger-irritation (ANG). Overall, there was partial invariance at both metric and scalar levels across gender and countries. Discriminant and convergent validity of the RESE scale was further examined in the Italian sample. Stronger patterns of association of POS with prosocial behavior, of ANG with low aggressive behavior problems and irritability, and of DES with low anxiety/depressive problems and shyness and high self-esteem were found.
