Self‐regulation of Group Members: The Case of Regulatory Focus

For a long time, research on motivation and (inter)group behaviour mainly focused on needs and motives, but did not take self‐regulation (i.e., the processes underlying motivated action) into account. Similarly, self‐regulation research concentrated on the regulation of the personal self, but did not study the regulation of the social self. The current article summarizes work applying self‐regulation approaches to intergroup behaviour. Within this approach, it has been shown (a) that the social self is regulated based on the same mechanisms as the personal self, (b) that intergroup contexts impact on group members’ self‐regulation strategies, and (c) that the fit between an individual's self‐regulation strategy and the behavioural options provided by the group impact on group liking and potentially also on the integration of the group into the self‐concept. The relation between current and earlier approaches to motivation in groups and further avenues for research on group‐based self‐regulation are discussed.     

Optimum sample size allocation to minimize cost or maximize power for the two‐sample trimmed mean test

When planning a study, sample size determination is one of the most important tasks facing the researcher. The size will depend on the purpose of the study, the cost limitations, and the nature of the data. By specifying the standard deviation ratio and/or the sample size ratio, the present study considers the problem of heterogeneous variances and non‐normality for Yuen's two‐group test and develops sample size formulas to minimize the total cost or maximize the power of the test. For a given power, the sample size allocation ratio can be manipulated so that the proposed formulas can minimize the total cost, the total sample size, or the sum of total sample size and total cost. On the other hand, for a given total cost, the optimum sample size allocation ratio can maximize the statistical power of the test. After the sample size is determined, the present simulation applies Yuen's test to the sample generated, and then the procedure is validated in terms of Type I errors and power. Simulation results show that the proposed formulas can control Type I errors and achieve the desired power under the various conditions specified. Finally, the implications for determining sample sizes in experimental studies and future research are discussed.     

The word concreteness effect occurs for positive,but not negative,emotion words in immediate serial recall

The present study examined the roles of word concreteness and word valence in the immediate serial recall task. Emotion words (e.g. happy) were used to investigate these effects. Participants completed study‐test trials with seven‐item study lists consisting of positive or negative words with either high or low concreteness (Experiments 1 and 2) and neutral (i.e. non‐emotion) words with either high or low concreteness (Experiment 2). For neutral words, the typical word concreteness effect (concrete words are better recalled than abstract words) was replicated. For emotion words, the effect occurred for positive words, but not for negative words. While the word concreteness effect was stronger for neutral words than for negative words, it was not different for the neutral words and the positive words. We conclude that both word valence and word concreteness simultaneously contribute to the item and order retention of emotion words and discuss how Hulme et al.'s (1997) item redintegration account can be modified to explain these findings.     

Decomposing self‐estimates of intelligence: Structure and sex differences across 12 nations

This study examines the structure of self‐estimates of intelligence (SEI) across 12 nations (Australia, Austria, Brazil, France, Iran, Israel, Malaysia, South Africa, Spain, Turkey, UK and US). Participants rated themselves on general and specific abilities from three popular models of intelligence: Gardner's multiple intelligences, Sternberg's triarchic theory of intelligence, and Goleman's emotional intelligence. The results showed that (a) laypeople across nations have similar and invariant concepts of intelligence, (b) concepts of intelligence are cross‐culturally closely related to academic notions of intellectual ability and (c) sex differences in general and specific SEI favouring men are consistent across countries. Male hubris and female humility in SEI seem independent of sex differences in actual cognitive ability and national levels of masculinity‐femininity. Furthermore, international mean differences in general SEI could not be attributed to discrepancies in national intelligence quotient (IQ) levels or to cultural variations.     

BIBLICAL AND THEISTIC ARGUMENTS AGAINST THE EVOLUTIONARY ARGUMENT AGAINST NATURALISM

Alvin Plantinga's evolutionary argument against naturalism states that evolution cannot produce warranted beliefs. In contrast, according to Plantinga, Christian theism provides (I) properly functioning cognitive faculties in (II) an appropriate cognitive environment, in accordance with (III) a design plan aimed at producing true beliefs. But does theism fulfill criteria I–III? Judging from the Bible, God employs deceit in his relations with humanity, rendering our cognitive functions unreliable (I). Moreover, there is no reason to suppose that God's purpose would be to produce true beliefs in humans (III). Finally, from the theistic/religious perspective, it is impossible to tell whether observations have natural or supernatural causes, which undermines an appropriate cognitive environment (II). Reliable identification of deceit or miracles could alleviate these problems, but the theistic community has failed to resolve this issue. Dismissal of parts of the Bible, or attempts to find alternative interpretations, would collapse into skepticism or deism. Thus, Plantinga's problem of epistemic warrant backfires on theism.     

视觉工作记忆中基于客体的存储机制：来自ERPs的证据

该研究以简单形状和颜色构成的客体为材料,采用延迟匹配范式,通过记录事件相关电位,以反映工作记忆表征与知觉输入间冲突的N270为指标,就视觉工作记忆中的客体存储机制进行了探讨。结果发现,无关维度特征变化与目标维度特征变化均可诱发N270。该结果表明,视觉工作记忆对客体目标特征进行存储时,无关特征亦自动得到选择加工,支持基于客体的存储说。     

提取抑制:来自听觉定向遗忘的证据

两个实验采用语音材料考察了词表表达方式下听觉通道的定向遗忘效应以及相应的机制。实验一中,采用2（组别）×2（词表）混合实验设计获得了听觉通道的定向遗忘效应,但是较为模糊,部分数据显示可能是额外的被试个体差异导致的;实验二中,采用2（性别）×2（词表）×2（条件）×2（科系）混合实验设计,严格控制了被试个体差异等因素,获得了较清晰的定向遗忘效应,且支持提取抑制理论。     

Psychological Flexibility at Work and Employees' Proactive Work Behaviour: Cross‐Level Moderating Role of Leader Need for Structure

How to promote employees to be proactive behaviourally is a significant issue in the literature because it would benefit organisations in several ways. Drawing on the acceptance and commitment model, we proposed a new antecedent, psychological flexibility that might contribute to employees' proactive work behaviour. Furthermore, we investigated how the contextual role of supervisor need for structure exhibits a cross‐level moderating effect on the relationship between employee psychological flexibility at work and proactive work behaviour based on interactionism. Data from 241 full‐time employees and their corresponding 45 managers indicated that employee psychological flexibility was positively associated with proactive work behaviour. More importantly, the supervisor need for structure played a moderating role, suggesting that employees would demonstrate greater proactive work behaviour especially when the supervisors have a high need for structure. Implications for psychological flexibility, proactivity, and person‐situation interactional research are discussed.
