Workaholism and work engagement: how are they similar? How are they different? A systematic review and meta-analysis

Workaholism and work engagement can be depicted, respectively, as the pathological and the healthy form of heavy work investment. In spite of their different definitions and outcomes on individual and organizational life, workaholism and work engagement are not clearly and adequately distinguished by scholars and researchers as they appear to show some overlapping features. The aim of this investigation was to meta-analyze available studies, selected by systematic review, on the relations between subdimensions of workaholism and work engagement. Thirty-five studies were eligible for analysis. Associations emerged between Working Excessively and Absorption (g = .34), Working Compulsively and Absorption (g = .28), and Working Excessively and Dedication (g = .14). Moreover, the results were not influenced by publication bias and showed nationality to be a significant moderator. Overall, these findings suggest that further research is necessary to extend our knowledge of workaholism, work engagement, and the relationship between the two, in order to disentangle commonalities and differences between them.     

视频游戏训练对执行功能的迁移效应

视频游戏训练是一种正处于探索阶段的执行功能训练方案,其对工作记忆和认知灵活性能产生迁移效应,对抑制的迁移结论尚不明确,这一结果不同无法通过考察迁移发生的泛化还是具体化机制得到解决,差异更有可能来自游戏训练本身。虽然真实游戏经验能产生迁移,但训练不一定能模拟经验对执行功能的迁移。这一方面受训练游戏类型的影响,另一方面与训练剂量有关。建议从丰富迁移机制等角度提高迁移效应。     

Hintikka’s Logical Revolution

Hintikka thinks that second-order logic is not pure logic, and because of Gödel’s incompleteness theorems, he suggests that we should liberate ourselves from the mistaken idea that first-order logic is the foundational logic of mathematics. With this background he introduces his independence friendly logic (IFL). In this paper, I argue that approaches taking Hintikka’s IFL as a foundational logic of mathematics face serious challenges. First, the quantifiers in Hintikka’s IFL are not distinguishable from Linström’s general quantifiers, which means that the quantifiers in IFL involve higher order entities. Second, if we take Wright’s interpretation of quantifiers or if we take Hale’s criterion for the identity of concepts, Quine’s thesis that second-order logic is set theory will be rejected. Third, Hintikka’s definition of truth itself cannot be expressed in the extension of language of IFL. Since second-order logic can do what IFL does, the significance of IFL for the foundations of mathematics is weakened.     

Expertise in the Game of Go and Levels of Visuospatial and Pattern Recognition Abilities

The results of existing research indicate higher levels of visuospatial and pattern recognition abilities in experts in the game of Go compared to novices. However, the tasks included in the research have been focused only on Go‐game situations. This study aimed to verify the hypothesis that experts in the game of Go would achieve higher scores, compared to novices, on behavioral tests measuring visuospatial abilities and that pattern recognition tests would be a predictor of group membership (experts, low‐skill players, novices). We consider that the game of Go can be treated as a special case of tasks related to visuospatial abilities and pattern recognition. Sixty men participated in the study, including 17 experts in the game of Go, 13 low‐skill players, and 30 novices. The results of behavioral tests—the advanced version of Raven's Progressive Matrices and the APIS‐Z Test's Visuospatial Abilities subscale, which measure pattern recognition and visuospatial abilities, respectively—confirmed the hypotheses.     

Theorizing Gender for Experimental Game Theory: Experiments with “Sex Status” and “Merit Status” in an Asymmetric Game

In experimental game-theoretic research, to the extent that sex has been considered at all, the approach has been to focus on the individual level of analysis. This paper reports the results of experiments designed to focus on sex/gender and to expand the level of analysis to include the institutional level. An asymmetric game was designed such that players in the male and female institutional locations had 3 and 2 alternatives, respectively. Players earned the institutional locations based on a test, so that top and bottom scorers respectively merited the 3- and 2-alternatives locations. Game-theoretic understandings of sex-of-player were compared to the expectations states theory concept of sex status; that is, men expect and are expected to perform more competently than women. Results indicated that top-scorer men and women behave similarly; bottom-scorer men resist their low merit status (behaving the most rationally of all player groups); bottom-scorer women accept their low merit status (behaving the most irrationally of all player groups). Whereas game theory cannot provide a coherent understanding of these findings, the concept of sex status helps to interpret the behavior of all four player groups and shows how judgments about rationality and irrationality depend critically on the interpretive framework used.     

The Basic Algebra of Game Equivalences

We give a complete axiomatization of the identities of the basic game algebra valid with respect to the abstract game board semantics. We also show that the additional conditions of termination and determinacy of game boards do not introduce new valid identities.En route we introduce a simple translation of game terms into plain modal logic and thus translate, while preserving validity both ways, game identities into modal formulae.The completeness proof is based on reduction of game terms to a certain minimal canonical form, by using only the axiomatic identities, and on showing that the equivalence of two minimal canonical terms can be established from these identities.     

两人和三人最后通牒博弈任务中嗓音吸引力对决策的影响

本研究用两人和三人最后通牒博弈任务探究男性嗓音吸引力对决策的影响。实验1发现, 高吸引力的嗓音会提高被试对不公平分配方案的接受率。实验2发现, 即使分配方案对第三方接受者公平, 对被试不公平, 第三方接受者的高吸引力嗓音仍然会提高被试对方案的接受率。综上, 嗓音吸引力可以诱发类似面孔吸引力的“美貌津贴”效应。     

面孔二态性对学前儿童信任行为的影响——来自人格标签的解释

面孔二态性是指成熟男性和女性经过青春期第二性征的发展后逐步形成了面孔上的性别特征,男性化与女性化是这一维度的两个水平。本研究探索面孔二态性是否会对学龄前儿童信任行为产生影响,并从幼儿对二态性面孔的人格标签角度来解释。实验1修订信任博弈任务（Trust game）,考察学前儿童信任行为是否会因搭档面孔的二态性（男性化和女性化）而不同,经历负性反馈后被试在下轮游戏中信任选择率是否会下降;实验2让学前儿童选择人格形容词来描述不同性别化的面孔,探讨幼儿对不同二态性面孔是否已形成不同的人格标签。结果表明学前儿童对女性化面孔信任选择率最高;在遭遇负性反馈后的下一轮游戏中,幼儿对他人的信任率显著下降;学前儿童认为女性化面孔更具有积极人格,而更多将男性化面孔与消极人格词汇匹配。由此,二态性面孔影响学前儿童的信任行为,在于他们对二态性面孔已形成不同的人格标签。     

A one-person doxastic characterization of Nash strategies

Within a formal epistemic model for simultaneous-move games, we present the following conditions: (1) belief in the opponents’ rationality (BOR), stating that a player believes that every opponent chooses an optimal strategy, (2) self-referential beliefs (SRB), stating that a player believes that his opponents hold correct beliefs about his own beliefs, (3) projective beliefs (PB), stating that i believes that j’s belief about k’s choice is the same as i’s belief about k’s choice, and (4) conditionally independent beliefs (CIB), stating that a player believes that opponents’ types choose their strategies independently. We show that, if a player satisfies BOR, SRB and CIB, and believes that every opponent satisfies BOR, SRB, PB and CIB, then he will choose a Nash strategy (that is, a strategy that is optimal in some Nash equilibrium). We thus provide a sufficient collection of one-person conditions for Nash strategy choice. We also show that none of these seven conditions can be dropped.     

Sex Differences in Self-reported Infidelity and its Correlates

We examined sex differences in the prevalence, incidence, reasons for, and consequences of infidelity. Participants (Study 1, 543 undergraduates in the Northwestern US; Study 2, 313 undergraduates and 233 community members in the Mid-Atlantic US), reported on infidelity by questionnaire. Using a broad definition of cheating, women reported being as unfaithful or more unfaithful than men. Men were more suspicious about cheating and more likely to discover the cheating than women. Women were more likely to break up with their partners, to begin new relationships after cheating, and to report reasons for cheating that may indicate a desire to switch long-term mates, such as being unhappy in the current relationship. Results are discussed in the context of evolutionary theory.
