The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.     

A Brief Group Cognitive-Behavioral Program for the Prevention of Depressive Symptoms in Chinese College Students

Depression is a problem among college students in China. Yet the use of preventative group cognitive-behavioral (CB) intervention is rare. One hundred and eighty Chinese college students who were identified as being at risk for depression were randomly assigned to three groups: 1) a brief group cognitive–behavioral (CB) intervention, 2) a supportive group (SG) intervention, and 3) a wait-list control condition. The Zung Self-Rating Depression Scale (SDS), the Zung Self-Rating Anxiety Scale (SAS), and the Chinese College Student Adjustment Scale (CCSAS) were administered at pre-test, post-test, and six-month follow-up. Analysis of variance (ANOVA) conducted among the three groups revealed that the CB group demonstrated significantly less increase in measures of primary symptoms of anxiety and depression than the wait-list controls at post-test and six-month follow-up. The prevention effect of the SG group was significant only at the six-month follow-up. CB participants also showed significantly greater improvements in social adjustment than did SG participants and controls at the post-test and six-month follow-up.     

Different paths to protest: predictors of collective action in the Occupy Movement

This study investigated the variables that shaped people's willingness to engage in collective action in the context of the Occupy Movement. Data were collected in 2011 from nonprotesting supporters at the New York City Occupy encampment and active occupiers at the New York and Atlanta encampments. Participants distinguished between different kinds of collective action based on cost. Furthermore, different predictors motivated distinct kinds of collective action. Identity and anger predicted low‐cost collective action. Efficacy predicted relatively costly collective action and mediated the link between identity and costly collective action. This study provides evidence that people draw distinctions between different actions based on cost and that, when it comes to predicting collective action, these distinctions matter.     

Joint Maximum Likelihood Estimation for Diagnostic Classification Models

Joint maximum likelihood estimation (JMLE) is developed for diagnostic classification models (DCMs). JMLE has been barely used in Psychometrics because JMLE parameter estimators typically lack statistical consistency. The JMLE procedure presented here resolves the consistency issue by incorporating an external, statistically consistent estimator of examinees’ proficiency class membership into the joint likelihood function, which subsequently allows for the construction of item parameter estimators that also have the consistency property. Consistency of the JMLE parameter estimators is established within the framework of general DCMs: The JMLE parameter estimators are derived for the Loglinear Cognitive Diagnosis Model (LCDM). Two consistency theorems are proven for the LCDM. Using the framework of general DCMs makes the results and proofs also applicable to DCMs that can be expressed as submodels of the LCDM. Simulation studies are reported for evaluating the performance of JMLE when used with tests of varying length and different numbers of attributes. As a practical application, JMLE is also used with “real world” educational data collected with a language proficiency test.     

Perceiving the World Through Group-Colored Glasses: A Perceptual Model of Intergroup Relations

Extensive research has investigated societal and behavioral consequences of social group affiliation and identification but has been relatively silent on the role of perception in intergroup relations. We propose the perceptual model of intergroup relations to conceptualize how intergroup relations are grounded in perception. We review the growing literature on how intergroup dynamics shape perception across different sensory modalities and argue that these perceptual processes mediate intergroup relations. The model provides a starting point for social psychologists to study perception as a function of social group dynamics and for perception researchers to consider social influences. We highlight several gaps in the literature and outline areas for future research. Uncovering the role of perception in intergroup relations offers novel insights into the construction of shared reality and may help devise new and unique interventions targeted at the perceptual level.     

Linking Maternal Socialization of Positive Emotions to Children’s Behavioral Problems: The Moderating Role of Self-Control

Little is known about how parents socialize children’s positive affect regulation during late childhood. Consequently, we examined how mothers’ reported responses to their children’s (aged 7–12 years) positive emotions were linked to children’s behavioral problems and how children’s self-control moderated these associations. Our results indicated that maternal encouragement of positive emotions predicted fewer externalizing behaviors, but only for youth with lower self-control. Maternal explanation about their children’s positive emotions was unrelated to youth’s behavioral problems. Lastly, maternal dismissing responses to their children’s positive emotions (i.e., reprimanding responses and discomfort) were related to more externalizing and internalizing in youth, and these effects were not dependent on the children’s self-control. The current study adds to the limited research on positive affect socialization and offers some evidence that youth’s self-control may serve as a vantage-sensitivity factor in the association between maternal positive affect socialization and youth adjustment.     

The role of retrieval mode and retrieval orientation in retrieval practice: insights from comparing recognition memory testing formats and restudying

The effectiveness of retrieval practice for aiding long-term memory, referred to as the testing effect, has been widely demonstrated. However, the specific neurocognitive mechanisms underlying this phenomenon remain unclear. In the present study, we sought to explore the role of pre-retrieval processes at initial testing on later recognition performance by using event-related potentials (ERPs). Subjects studied two lists of words (Chinese characters) and then performed a recognition task or a source memory task, or restudied the word lists. At the end of the experiment, subjects received a final recognition test based on the remember–know paradigm. Behaviorally, initial testing (active retrieval) enhanced memory retention relative to restudying (passive retrieval). The retrieval mode at initial testing was indexed by more positive-going ERPs for unstudied items in the active-retrieval tasks than in passive retrieval from 300 to 900 ms. Follow-up analyses showed that the magnitude of the early ERP retrieval mode effect (300–500 ms) was predictive of the behavioral testing effect later on. In addition, the ERPs for correctly rejected new items during initial testing differed between the two active-retrieval tasks from 500 to 900 ms, and this ERP retrieval orientation effect predicted differential behavioral testing gains between the two active-retrieval conditions. Our findings confirm that initial testing promotes later retrieval relative to restudying, and they further suggest that adopting pre-retrieval processing in the forms of retrieval mode and retrieval orientation might contribute to these memory enhancements.
