Unbalanced triangle in the social dilemma of trust: Internet studies of real‐time,real money social exchange between China,Japan, and Taiwan

Using a dyadic game theory paradigm, three experiments on the social dilemma of trust were conducted over the Internet in real time, involving real money. It was predicted and found that in‐group favouritism in trusting behaviour was contingent on historical relationships between societies. In the China–Japan experiment, mainland Chinese but not Japanese trusted and made fair allocations to in‐group members more than out‐group members, and out‐group trust was best predicted by positive stereotypes of the out‐group for Chinese and identity for Japanese. In the China–Taiwan experiment, Taiwanese but not Mainland Chinese trusted in‐group members more than out‐group members, and in‐group trust for Taiwanese was best predicted by perceptions of current realistic threats. In the Taiwan–Japan experiment, there were slight in‐group favouring tendencies in trust, and positive stereotypes of the out‐group were the best predictors of out‐group trust. Japanese were unique in not displaying in‐group favouring behaviour at all, whereas both Chinese and Taiwanese were context specific in their in‐group favouritism. Stereotypes, social identities, perceptions of realistic threat, and historical anger made significant contributions to predicting trusting behaviour, but overall these survey measures only accounted for small and inconsistent amounts of variance across the three experiments.     

You are what you tweet: Personality expression and perception on Twitter

Microblogging services such as Twitter have become increasingly popular in recent years. However, little is known about how personality is manifested and perceived in microblogs. In this study, we measured the Big Five personality traits of 142 participants and collected their tweets over a 1-month period. Extraversion, agreeableness, openness, and neuroticism were associated with specific linguistic markers, suggesting that personality manifests in microblogs. Meanwhile, eight observers rated the participants’ personality on the basis of their tweets. Results showed that observers relied on specific linguistic cues when making judgments, and could only judge agreeableness and neuroticism accurately. This study provides new empirical evidence of personality expression in naturalistic settings, and points to the potential of utilizing social media for personality research.     

The Effects of School Bonding on High School Seniors’ Academic Achievement

The authors examine the effects of school bonding on academic achievement (measured by math achievement scores) in a sample of 12th graders from the Educational Longitudinal Study of 2002 ( Ingels, Pratt, Rogers, Siegel, & Stutts, 2005 ). Components of school bonding have proximal and distal effects on academic achievement. Attachment to school and school involvement had direct effects on achievement; attachment to teachers and school commitment behaviors had indirect effects on achievement through school‐related delinquency and prior achievement. Implications for counselors are discussed.

Disruption of memory reconsolidation impairs storage of other, non-reactivated memory

Two hypotheses were tested in this study. First, blockade of neural activity by lidocaine immediately following the retrieval of a memory may impair the reconsolidation and subsequent expression of that memory. Second, a non-retrieved memory would not be affected by this lidocaine treatment. Since the basolateral nucleus of the amygdala (BLA) is involved in emotion-related memory, an intra-BLA lidocaine infusion was used immediately after the retrieval of two emotion-related memories, the step-through passive avoidance response (PA) and cocaine-induced conditioned place preference (CPP). Intra-BLA lidocaine infusion immediately after cocaine-induced CPP retrieval diminished CPP magnitude in retests. However, intra-BLA lidocaine infusion alone did not affect cocaine-induced CPP performance. Intra-BLA lidocaine infusion immediately after PA retrieval decreased PA performance in retests. Omission of PA retrieval procedure, intra-BLA lidocaine infusion did not affect subsequent PA performance. Surprisingly, intra-BLA lidocaine infusion immediately following the retrieval of PA or cocaine-induced CPP diminished both PA and cocaine-induced CPP performance in the retests. Finally, Fos-staining results revealed that a number of BLA neurons were activated by the retrieval of both cocaine-induced CPP and PA. We conclude that inactivation of neural activity in BLA immediately following retrieval of a fear or cocaine-conditioned memory can impair subsequent expression of both memories. More importantly, retrieval of a memory does not seem to be an absolute condition for rapidly changing the memory.     

The effects of functional group counseling on inspiring low-achieving students' self-worth and self-efficacy in Taiwan

In this study, we investigated the effects of functional group counseling on inspiring low achievers' self-worth and self-efficacy in Taiwan. Forty-three 10th grade low-achieving students volunteered as the Experimental Group to join a 24-week intervention, which integrated and utilized functional group counseling; another 51 10th grade low-achieving students volunteered to be Comparison Group I. In addition, 43 10th grade moderate or high academic achieving students volunteered to be Comparison Group II. All participants completed the Vocational School Student Questionnaire at the beginning and end of this study to measure their self-worth and self-efficacy. In addition, six target students (two boys and four girls) with the lowest total scores on self-worth or self-efficacy in the pretest were selected from the Experimental Group to be interviewed at the end of the intervention and observed weekly. Analyses of variance, analyses of covariance, and paired t-tests assessed the similarity and differences among groups. The initial findings were as follows: Experimental group students had significantly higher scores on self-efficacy and self-worth than both Comparison Group I and Group II students and functional group counseling was shown to significantly affect the low-achieving students. Qualitative results from interviews and observations were used for triangulation and consolidation of quantitative results. Implications of the study included the recommended use of functional group counseling with low-achieving students.     

The influence of the perception of a familial climate on job performance: mediation of loyalty to supervisors and moderation of filial behaviour

With a collectivist cultural perspective, we examined the positive effects of employees' perceptions of a familial climate on loyalty to supervisors, the mediation of loyalty between perception of a familial climate and job performance, and the moderation of employees' filial behaviour on the relationship between perception of a familial climate and loyalty. The participants consisted of 247 supervisor-and-subordinate dyads in Taiwan. The results supported our hypotheses. Through the mechanisms of family behaviour transference, social identification and supervisor-subordinate exchange, perception of an organizational familial climate enhanced loyalty to supervisors. Furthermore, loyalty to supervisors mediated the relationship between perception of a familial climate and job performance. Filial behaviour moderated the relationship between perception of a familial climate and loyalty; thus, the relationship of perception of a familial climate and loyalty was stronger for employees with low levels of filial behaviour and weaker for employees with high levels of filial behaviour. These findings are discussed in terms of their theoretical and practical implications for future research and management practices.     

A computer-based intervention to reduce internalized heterosexism in men

Internalized heterosexism (IH) is a strong predictor of the psychological well-being of lesbian, gay, bisexual (LGB), or other same-sex attracted individuals. To respond to the call for interventions to address IH, the current study developed and tested an online intervention to reduce IH among gay, bisexual, and other same-sex attracted men. A total of 367 self-identified same-sex attracted adult males were recruited through various nationwide LGB-related sources and were assigned by birth month to either the experimental condition (focusing on IH reduction) or the control condition (a similarly structured invention focusing on stress management); 290 of these participants completed the intervention and all post-intervention measures. Mean levels of IH were compared by condition, indicating significant differences on the IH global score and 2 of the 3 IH subscale scores between the participants in the 2 conditions. The study findings support the promise of using the Internet to deliver IH interventions. Implications for research and practice are discussed.     

Propositional Reasoning that Tracks Probabilistic Reasoning

This paper concerns the extent to which uncertain propositional reasoning can track probabilistic reasoning, and addresses kinematic problems that extend the familiar Lottery paradox. An acceptance rule assigns to each Bayesian credal state p a propositional belief revision method ${\sf B}_{p}$ , which specifies an initial belief state ${\sf B}_{p}(\top)$ that is revised to the new propositional belief state ${\sf B}(E)$ upon receipt of information E. An acceptance rule tracks Bayesian conditioning when ${\sf B}_{p}(E) = {\sf B}_{p|_{E}}(\top)$ , for every E such that p(E)?>?0; namely, when acceptance by propositional belief revision equals Bayesian conditioning followed by acceptance. Standard proposals for uncertain acceptance and belief revision do not track Bayesian conditioning. The ??Lockean?? rule that accepts propositions above a probability threshold is subject to the familiar lottery paradox (Kyburg 1961), and we show that it is also subject to new and more stubborn paradoxes when the tracking property is taken into account. Moreover, we show that the familiar AGM approach to belief revision (Harper, Synthese 30(1?C2):221?C262, 1975; Alchourrón et al., J Symb Log 50:510?C530, 1985) cannot be realized in a sensible way by any uncertain acceptance rule that tracks Bayesian conditioning. Finally, we present a plausible, alternative approach that tracks Bayesian conditioning and avoids all of the paradoxes. It combines an odds-based acceptance rule proposed originally by Levi (1996) with a non-AGM belief revision method proposed originally by Shoham (1987).     

反向眼跳的实验范式、机制及影响因素

反向眼跳任务是研究内源性眼跳的主要方法。1978年,Hallett在研究中首次使用了反向眼跳的实验任务。实验中要求被试抑制对外围目标的注视,并注视它的相反位置。反向眼跳任务是研究行为控制以及注意功能的有效范式。目前认为反向眼跳任务中的朝向眼跳和反向眼跳计划是同时加工并相互竞争的,并且反向眼跳的产生与额顶叶皮层下组织有关。反向眼跳会受到多种因素的影响,例如,空白效应、工作记忆、认知老化、目标离心率等。
