The influence of environmental context in interpersonal observation–execution

Cyclical upper-limb movements involuntarily deviate from a primary movement direction when the actor concurrently observes incongruent biological motion. We examined whether environmental context influences such motor interference during interpersonal observation–execution. Participants executed continuous horizontal arm movements while observing congruent horizontal or incongruent curvilinear biological movements with or without the presence of an object positioned as an obstacle or distractor. When participants were observing a curvilinear movement, an object located within the movement space became an obstacle, and, thus, the curvilinear trajectory was essential to reach into horizontal space. When acting as a distractor, or with no object, the curvilinear trajectory was no longer essential. For observing horizontal movements, objects were located at the same relative locations as in the curvilinear movement condition. We found greater involuntary movement deviation when observing curvilinear than horizontal movements. Also, there was an influence of context only when observing horizontal movements, with greater deviation exhibited in the presence of a large obstacle. These findings suggest that the influence of environmental context is underpinned by the (mis-)matching of observed and executed actions as incongruent biological motion is primarily coded via bottom-up sensorimotor processes, whilst the congruent condition incorporates surrounding environmental features to modulate the bottom-up sensorimotor processes.     

Why are Extraverts more Satisfied? Personality,Social Experiences,and Subjective Well‐being in College

It is widely appreciated that extraversion is associated with greater subjective well‐being. What is not yet clear is what mechanisms relate the two. In two longitudinal studies, we explored whether extraversion is prospectively associated with higher levels of satisfaction during college through influencing college social experiences using longitudinal cross‐lagged mediation models. In both studies, students' extraversion at the beginning of college predicted their subjective well‐being 4 years later. In both studies, extraversion at the beginning of college predicted a variety of self‐reported and peer‐reported social experiences (e.g. feelings of belonging and size of social network). We tested whether qualitative or quantitative aspects of social experiences explained the association between extraversion and subjective well‐being. In the first study, neither type of social experience explained the effect of extraversion on satisfaction. Only qualitative social experiences in the second study were instrumental in explaining this effect. The results suggest that extraversion's ability to create better social experiences can play a role in extraverts' greater subjective well‐being, but these experiences are not the only reason extraverts are happier and more satisfied.

Discounting input from older adults: the role of age salience on partner age effects in the social contagion of memory

Three experiments examined the impact of partner age on the magnitude of socially suggested false memories. Young participants recalled household scenes in collaboration with an implied young or older adult partner who intentionally recalled false items. In Experiment 1, participants were presented with only the age of their partner (low age-salience context); in Experiment 2, participants were presented with the age of their partner along with a photograph and biographical information about their partner (high age-salience context); in Experiment 3, age salience was varied within the same experiment. Across experiments, participants in both the low age-salience and high age-salience contexts incorporated their partners’ misleading suggestions into their own subsequent recall and recognition reports, thus demonstrating social contagion with implied partners. Importantly, the effect of partner age differed across conditions. Participants in the high age-salience context were less likely to incorporate misleading suggestions from older adult partners than from young adult partners, but participants in the low age-salience context were equally likely to incorporate suggestions from young and older adult partners. Participants discount the memory of older adult partners only when age is highly salient.     

父母教养方式对初中生攻击行为的影响:越轨同伴交往和自我控制的作用

以631名初中生为被试,采用问卷法考察父母教养方式与初中生攻击行为的关系,同时探讨越轨同伴交往的中介作用,以及该作用是否受自我控制的调节。结果发现：（1）消极父母教养方式对越轨同伴交往、攻击行为均有显著的正向预测作用;（2）越轨同伴交往在消极父母教养方式与初中生攻击行为之间起部分中介作用;（3）自我控制可以调节越轨同伴交往对初中生攻击行为的作用,对于低自我控制个体,越轨同伴交往起部分中介作用;对于高自我控制个体,越轨同伴交往的中介效应不显著,消极父母教养方式对攻击行为仅有直接作用。     

情绪感染问卷的中国化修订与信效度检验

该研究旨在编制情绪感染问卷并探讨问卷的信度与效度,问卷以Doherty编制的《情绪感染问卷》(the emotional contagion scale)作为蓝本,删除了不适合东方文化的项目,增加了符合中国人的情绪情境和展现情绪方式的项目,经过预测修订后,最终问卷包含5个维度25个项目,正式施测共回收747份有效问卷,并对数据进行了信效度检验。结果表明,探索性因素分析KMO为0.802,总问卷的标准化的Cronbach’sα系数为0.852,项目分析表明项目的鉴别指数D值在0.340~0.479之间,验证性因素分析具有较好的模型拟合度,问卷的重测信度与效标关联效度均达到显著水平。情绪感染问卷的信效度均达到了测量学的要求。     

Improving oral reading fluency with a peer-mediated intervention

This study examined the effects of an experimentally derived, peer-delivered reading intervention on the oral reading fluency of a first-grade student who had been referred for poor reading fluency. Same-grade peers were trained to lead the target student through a structured intervention protocol based on the results of a brief experimental analysis. Results indicated that reading improvements were obtained and are discussed in terms of selecting efficient interventions for use by peers.     

Prospective linkages between peer victimization and externalizing problems in children: a meta-analysis

Previous meta-analytic research has shown both concurrent and prospective linkages between peer victimization and internalizing problems in youth. However, the linkages between peer victimization and externalizing problems over time have not been systematically examined, and it is therefore unknown if externalizing problems are antecedents of victimization, consequences of victimization, both, or neither. This study provides a meta-analysis of 14 longitudinal studies examining prospective linkages between peer victimization and externalizing problems (n = 7,821). Two prospective paths were examined: the extent to which peer victimization at baseline predicts future residualized changes in externalizing problems, as well as the extent to which externalizing problems at baseline predict future residualized changes in peer victimization. Results revealed significant associations between peer victimization and subsequent residualized changes in externalizing problems, as well as significant associations between externalizing problems and subsequent residualized changes in peer victimization. Hence, externalizing problems function as both antecedents and consequences of peer victimization.     

A multilevel multitrait‐multimethod analysis of self‐ and peer‐reported daily affective experiences

We examined the psychometric properties of an experience‐sampling measure of affect (PANAS) using data from self‐ and peer reports. A multivariate multilevel model was used to assess the reliability of the latent PANAS scales at the within‐ and between‐person level. Findings suggest satisfying internal consistencies for self‐ and peer reports of affective experiences at both levels of analysis. Convergent and discriminant validity of the two affect scales were examined by means of a multilevel multitrait‐multimethod approach (MLM‐MTMM) indicating distinct findings at the within‐ and between‐person level. These findings provide further insights into the structural relations between the two PANAS scales: Whereas positive and negative affect were unrelated at the between‐person level; they were negatively correlated at the within‐person level.

One’s own reasoning

Abstract

Responding to Cappelen and Dever’s claim that there is no distinctive role for perspectivality in epistemology, I argue that facts about the outcomes of one’s own reasoning processes may have a different evidential significance than facts about the outcomes of others’.     

DRD2基因TaqIA多态性与同伴侵害对青少年早期抑郁的交互作用

本研究运用问卷法与DNA分型技术,对1063名青少年(初次测评年龄为12.32±0.47岁,50.3%女生)进行间隔2年的追踪调查,考察DRD2基因TaqIA多态性与同伴身体侵害和关系侵害对青少年早期抑郁的交互作用及其性别差异。结果发现,TaqIA多态性与身体侵害、关系侵害均对男青少年抑郁存在显著的交互作用。在携带A2A2基因型的男生中,身体侵害和关系侵害可以显著正向预测其抑郁水平,而在携带A1等位基因的男生中,同伴侵害对抑郁无预测作用。此外,TaqIA多态性与身体侵害、关系侵害对女生抑郁均无显著交互作用。研究结果提示,同伴侵害是一种重要的候选环境指标,与TaqIA多态性交互影响青少年早期抑郁,并且性别在这一基因×环境交互作用中起到重要的调节效应。
