情绪Stroop效应：威胁驱动还是反应偏差？

为了考查情绪Stroop效应的产生机制是威胁驱动还是反应偏差,本研究进行了两个实验.实验一用一般负性情绪词语和中性词语作为实验材料,实验二用威胁性的情绪图片和中性图片作为实验材料.每个实验均要求一组被试做按键反应,另一组被试做摇杆反应.结果发现,当实验材料为词语时,未出现情绪Stroop效应;当实验材料为威胁性图片时,无论是趋向性反应方式还是回避性反应方式,都出现了情绪Stroop效应.本研究结果支持威胁驱动机制.     

Correlates of youth sport attrition: A review and future directions

ObjectivesThis review aims to (a) identify correlates of youth sport attrition, (b) frame correlates within a multilevel model of youth sport participation (i.e., biological, intra-personal, inter-personal, institutional, community, and policy levels), and (c) assess the level of evidence for each correlate.DesignReview paper.MethodsSystematic review method.ResultsEntering relevant search terms into PubMed, PsycINFO, SPORTDiscus and Web of Knowledge databases identified 23 articles with a total of 8345 participants. Satisfactory articles largely examined sport-specific attrition and sampled youth from western countries (e.g., Canada, France, Spain, United States). Of the 141 correlates examined, most were framed at the intrapersonal (90) and inter-personal levels (43). The level of evidence for each correlate (i.e., high, low, insufficient) was systematically assessed based on the quantity and quality of supporting articles. In total, 11 correlates were categorized as having a high quality level of evidence and 10 as having a low quality. High quality correlates included, among others, age, autonomy, perceived competence, relatedness, and task climate.ConclusionsOverall, established correlates of youth sport attrition are largely social in nature. Future directions surrounding (a) the need to examine correlates at lower (i.e., biological level) and higher (i.e., institutional, community, policy) analytic levels, (b) to sample participants from more culturally diverse societies and (c) to examine sport-general attrition are offered.     

Mental imagery increases self-determined motivation to exercise with university enrolled women: A randomized controlled trial using a peer-based intervention

ObjectivesThe purpose of this study was to examine the effects of a peer-based mental imagery intervention on the self-determined motivation and cardio-respiratory fitness of university enrolled women.DesignRandomized controlled trial.Method43 University enrolled women were randomized to peer-mentored or peer-mentored plus mental imagery conditions while 32 completed three meetings with peer-mentors and post-testing (M^age = 19.91; SD = 1.70).ResultsSignificant improvements in cardio-respiratory endurance, ratings of perceived endurance, and self-determined motivation to exercise were observed across both study conditions. Participants assigned to the peer mentored plus mental imagery condition reported significantly greater increases in self-determined motivation to exercise at post-test compared to those in the peer-mentored condition.ConclusionsPeer-based interventions are a viable way to improve fitness and health outcomes while mental imagery appears to be associated with increases in autonomous forms of exercise motivation.     

Need fulfillment and motivation in physical education predict trajectories of change in leisure-time physical activity in early adolescence

ObjectivesWe examined (1) how psychological need fulfillment and motivation in physical education and leisure-time physical activity change during early adolescence, and (2) the degree to which need fulfillment and motivation predict trajectories of change in physical activity.DesignLongitudinal survey.MethodsStudents (N = 134, ages 10–13 years) completed surveys assessing perceived competence, autonomy, relatedness, intrinsic motivation, and identified, introjected, and external regulations in physical education, and leisure time physical activity each semester in school for 3 years.ResultsUnconditional growth models showed an average increase in physical activity. Competence also increased, while autonomy and relatedness, and identified and introjected regulation decreased. Conditional models showed that students with higher levels of autonomy, relatedness, intrinsic motivation, and identified regulation had higher levels of physical activity at baseline and throughout the study. Students with lower levels of autonomy, relatedness, intrinsic motivation, and identified regulation experienced significantly greater increases in physical activity, but these effects were very small.ConclusionsNeed fulfillment and motivation variables positively predict physical activity. While youth with lower levels of need fulfillment and motivation have lower levels of physical activity, they also tend to increase physical activity levels more across early adolescence. These associations highlight how physical education experiences in early adolescence may influence change in physical activity, and suggest efforts to foster need fulfillment and autonomous regulation in physical education may promote physical activity.     

Followership at a distance: Follower adjustment to distal leadership during COVID-19

Leader distance theory has received scant empirical attention in the extant literature; however, the “work from home” orders associated with COVID-19 have made this theory and its empirical findings highly relevant for organizations. Our study integrates leader distance theory and followership theory to understand how follower role beliefs affect follower effort, performance, and withdrawal under physical leader distance and varying conditions of leader interaction frequency. Using a three-wave survey methodology with 260 adults working remotely, our study finds that followers' levels of effort, performance, and withdrawal were contingent on leader interaction frequency. Specifically, followers with a coproduction role orientation, who see their role as more collaborative, reported higher levels of effort under conditions of high leader interaction. Furthermore, the indirect effect of coproduction on follower performance and withdrawal via effort was moderated by leader interaction frequency. The results for followers with passive role orientations, however, were in the opposite direction. These followers reported less effort when leader interaction was high, and the mediational chain predicting performance and withdrawal was contingent on leader interaction frequency. Our study contributes to the ongoing conversation about the positive and negative effects of leader distance and positions followership characteristics as important boundary conditions of distal leadership.     

At the core of cyberaggression: A group-based explanation

In this study, prototypicality of the aggressor was tested as a group-level factor predicting social media users’ active participation in cyberaggression. Participants were exposed to a fictitious conversation, in which either a prototypical versus non-prototypical user posted an aggressive comment as a reply to a provocative comment. In line with self-categorization theory, we hypothesized that bystander participants would post an aggressive comment and rate the aggression as acceptable to a greater extent in the prototypical than in the non-prototypical condition. Furthermore, we predicted that perceived normativity of aggression would mediate the effect of prototypicality. Results supported these predictions and showed that prototypical members affect the extent to which collective aggressive behaviors in online interactions are approved and enacted. These findings highlight the importance of group-level factors in the study of cyberaggression and provide important information for understanding the psychological underpinnings of collective forms of online aggression.     

分段是视频学习的有效方式吗?

教育心理学中的分段原则认为,将视频学习材料分割成几个小片段进行学习的效果更好。以往关于分段的研究通过两个角度的操纵考察了分段在学习中的作用,一方面是交互性角度,学习者自己控制的分段及系统分段;另一方面是结构性角度,分段是在任意时间点划分和有意义时间点上划分。通过对以往研究结果的整理发现,大部分研究证明分段学习相较于连续学习的成绩更好,并且能降低学习者在学习过程中的感知难度, 提高积极的情感状态,但是对心理努力的影响比较微弱。研究者们从事件分割理论和认知负荷理论的视角对分段的效果做出了解释。未来研究需要继续关注分段的边界条件、拓宽研究的范围、探究分段的认知神经基础等不断完善分段原则在教学中的应用。     

有“新”同享：共有消费促进对不熟悉产品的选择*

共有消费是多位消费者共同参与并承担开销的一种常见的消费活动。本研究基于风险转移理论, 探究了消费情境(单独消费vs.共有消费)对不熟悉产品偏好的作用机理及边界条件。通过5个实验, 结果发现：相比于单独消费情境下的消费者, 在共有消费情境下的消费者更愿意尝试不熟悉的产品。原因在于共有消费情境会转移消费风险, 使得消费者对不熟悉产品的感知风险降低。但是该效应仅发生于产品风险较低的产品。同时, 当共有消费群体的关系较为疏远时, 该效应会消失甚至逆转。     

Associations between parent perceived social cognitive factors and child objectively measured physical activity behaviors among preschool-aged children

Grounded in social cognitive theory (SCT), this study sought to examine whether parents perceived social cognitive factors regarding children's physical activity (PA) behaviors were associated with preschool children's moderate-to-vigorous PA (MVPA) levels. A total of 142 Hong Kong parent-child pairs from five preschools/childcare centers completed all assessments in the cross-sectional study. Children’s (42% girls; mean age = 4.52 ± 0.67 years) PA was measured through accelerometers. Parents (74% mothers; mean age = 37.38 ± 4.63 years) completed a paper-based questionnaire assessing the social cognitive factors on their children’s PA participation. The data were analyzed using latent variable structural equation modeling. Findings revealed that the model showed acceptable fit with the data: χ² (23) = 38.14, p = .025, χ²/df = 1.66, CFI = 0.955, TLI = 0.929, RMSEA = 0.068, 90% CI [0.025, 0.106], and SRMR = 0.072. The model accounted for 39.1% of the variance in the PA behavior of preschool-aged children. Structural equation modelling revealed parental self-efficacy (β = 0.29, 95% CI [0.95, 0.49]) and goal setting (β = 0.25, 95% CI [0.06, 0.44]) were directly associated with children’s MVPA. Outcome expectations (β = 0.09, 95% CI [0.01, 0.03]) and goal setting (β = 0.18, 95% CI [0.05, 0.32]) mediated the association between parental self-efficacy and children’s MVPA. Indirect associations of parental self-efficacy from setting goals via parental support (β = 0.15, 95%CI [0.02, 0.30]) and perceived barriers (β = 0.15, 95% CI [0.05, 0.28]) were uncovered. Results supported the use of SCT in understanding how the parents perceived social cognitive factors predict the PA behaviors of young children. This study provides insight into whether these theoretical variables could be modified or promoted in future intervention programs. Enhancing parents’ abilities to ensure preschool-aged children are physically active is of great importance given the global decline in PA among children.     

“You Didn’t Cause Racism,and You Have to Solve it Anyways”: Antiracist Adaptations to Dialectical Behavior Therapy for White Therapists

There are currently no published studies that investigate or discuss the cultural responsiveness of Dialectical Behavior Therapy (DBT) to the needs of Black/African-American clients. In addition, no published scholarly works offer guidance to therapists on how to practice antiracism within the context of delivering evidence-based treatment. Methods for developing a culturally responsive antiracist treatment are discussed within a dialectical framework and from the perspective of critical race psychology. We propose that an antiracist adaptation to DBT is needed to correct for context minimization errors in the DBT model that create an invisibility of racism. Recommendations are made for an additional DBT Therapist Agreement that encourages labeling and targeting therapist treatment-interfering racist behavior. An additional Therapist Consultation Agreement is also proposed to guide therapist antiracist advocacy and functional validation for Black/African-American clients. The DBT technology is used in conjunction with other multicultural theoretical models to recommend strategies for developing White DBT therapists’ antiracist competencies. Future directions for developing critical race psychological research are discussed.
