Engagement Attentional Bias toward Value-Associated Stimuli

Recent evidence has shown that learning to associate the value of behavioral outcomes with specific stimuli (i.e., value learning/association) can induce attentional capture in a subsequent visual search task. Here we investigated the component of attentional bias toward value-associated stimuli in the dot-probe paradigm. In the training phase, participants learned to associate nonsense shape outlines with monetary wins or losses. The shapes were then used as cues in an explicit no feedback dot-probe task. Probe appeared at either the salient (congruent trial) or nonsalient location (incongruent trial). Results indicate attentional bias toward value-associated stimuli, futher more this attentional bias is driven by an engagement bias.     

Work-group characteristics and performance in collectivistic and individualistic cultures

The authors conducted a cross-cultural longitudinal investigation of the effects of culture (individualism-collectivism dichotomy) on group characteristics (functional heterogeneity, preference for teamwork, group potency, outcome expectation) and on performance of 83 work groups performing 2 decision-making tasks over a 15-week period. The individualists (U.S. students) reported higher levels of functional heterogeneity and group potency and attained higher levels of group performance than did the collectivists (Korean students). In addition, culture and time interacted to influence ratings of group potency and outcome expectation. The difference in ratings of group potency between individualists and collectivists increased over time. Outcome expectation was greater among the collectivists in Time 1 and among the individualists in Time 2. The authors discuss implications for future cross-cultural group research and international management.

A psychometric analysis of chess expertise

This study introduces the Amsterdam Chess Test (ACT). The ACT measures chess playing proficiency through 5 tasks: a choose-a-move task (comprising two parallel tests), a motivation questionnaire, a predict-a-move task, a verbal knowledge questionnaire, and a recall task. The validity of these tasks was established using external criteria based on the Elo chess rating system. Results from a representative sample of active chess players showed that the ACT is a very reliable test for chess expertise and that ACT has high predictive validity. Several hypotheses about the relationships between chess expertise, chess knowledge, motivation, and memory were tested. Incorporating response latencies in test scores is shown to lead to an increase in criterion validity, particularly for easy items.     

Inferring the structure of latent class

Present optimization techniques in latent class analysis apply the expectation maximization algorithm or the Newton-Raphson algorithm for optimizing the parameter values of a prespecified model. These techniques can be used to find maximum likelihood estimates of the parameters, given the specified structure of the model, which is defined by the number of classes and, possibly, fixation and equality constraints. The model structure is usually chosen on theoretical grounds. A large variety of structurally different latent class models can be compared using goodness-of-fit indices of the chi-square family, Akaike’s information criterion, the Bayesian information criterion, and various other statistics. However, finding the optimal structure for a given goodness-of-fit index often requires a lengthy search in which all kinds of model structures are tested. Moreover, solutions may depend on the choice of initial values for the parameters. This article presents a new method by which one can simultaneously infer the model structure from the data and optimize the parameter values. The method consists of a genetic algorithm in which any goodness-of-fit index can be used as a fitness criterion. In a number of test cases in which data sets from the literature were used, it is shown that this method provides models that fit equally well as or better than the models suggested in the original articles.     

Help yourself by helping others: The joint impact of group member organizational citizenship behaviors and group cohesiveness on group member objective task performance change

This paper examines how a group member's individual‐targeted citizenship behavior (OCBI) and organization‐targeted citizenship behavior (OCBO) interact with a salient group‐level contextual variable, group cohesiveness, to foster positive change for that group member, starting with job self‐efficacy change, and followed by objective task performance change. Over a span of 6 months, we engaged in multilevel, multisource, multistage data collection and surveyed 587 members in 83 work groups. Our results indicate that a group member's OCBI, in comparison with OCBO, is more positively related to his or her job self‐efficacy change. Group cohesiveness was found to attenuate the relationship between a group member's OCBI and job self‐efficacy change, and conversely, to accentuate the relationship between a group member's OCBO and job self‐efficacy change. Furthermore, a group member's job self‐efficacy change mediated the interactive effects of the group member's OCBI and group cohesiveness (as well as the group member's OCBO and group cohesiveness) on his or her objective task performance change.     

以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。     

具体情绪及非依随反馈方式对自我妨碍的影响

该研究采用实验法考察了具体情绪以及非依随反馈方式对自我妨碍的影响。被试为104名大学生。结果表明：1）愉快组被试做出的决策型自我妨碍行为较少;恐惧组被试做出的回避型自我妨碍较多。2）两种非依随反馈方式对自我妨碍的影响没有显著差异。3）无论是决策型自我妨碍还是回避型自我妨碍,男生均高于女生。     

Very brief exposure II: the effects of unreportable stimuli on reducing phobic behavior

This experiment compared the effects of exposure to masked phobic stimuli at a very brief stimulus-onset asynchrony on spider-phobic and non-phobic individuals. Participants were identified through a widely used questionnaire and a Behavioral Avoidance Test (BAT) with a live, caged tarantula to establish baseline levels of avoidance. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. Preliminary masking experiments showed that independent samples of participants from the same populations failed to recognize these stimuli. Participants in the main experiment reported ratings of subjective distress immediately before and after the exposure manipulation. Then they engaged in the BAT once again. Very brief exposure to images of spiders reduced phobic participants' avoidance of the tarantula. No effects were evidenced on subjective distress, or on non-phobic participants. Theoretical implications for the non-conscious basis of fear are discussed.
