The Relationship between Online Game Experience and Multitasking Ability in a Virtual Environment

Online game playing has become popular entertainment, yet its relationship with individuals' multitasking ability was inconsistent. Types of online game genre so far have not been compared and may be associated with multitasking abilities. This study proposed to explore the relationships between types of online game playing and multitasking ability, using Edinburgh Virtual Errands Test (EVET). One hundred and sixteen participants playing different online game genres, including multiplayer online battle arena (MOBA), other online game playing, and no‐online game playing were compared. Each participant was required to fill in Chen's Internet Addiction Scale and the Internet Usage Questionnaire and perform EVET and working memory tests. The results showed a positive correlation between multitasking ability and working memory. In addition, a positive association was found between MOBA‐type gaming and multitasking abilities measured by EVET. In conclusion, MOBA‐type gaming compared with other game playing is associated with better multitasking abilities in a virtual environment.Copyright © 2017 John Wiley & Sons, Ltd.     

Assessment of Psychopathic Traits in Singaporean Adolescents: Validation of the Antisocial Process Screening Device (APSD)

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.     

Influence of plastic strain localisation on the mechanical properties of metal matrix composites

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible.     

Cultural influences in acquiescent response: A study of trainer evaluation biases

The current study is developed to identify factors that affect trainees’ acquiescent tendency in organizational trainer evaluations. We posit that conflict‐handling style affects ones tendency to acquiesce in trainer evaluations, and this relationship is regulated by cultural influence. Surveys were sent to employees with training experience in Taiwan and North America, 395 valid responses were collected. Results showed that the two individual conflict‐handling styles: non‐confrontation style and dominating style, are positively related to acquiescent tendency; and their relationship is found moderated by the influence of Confucian work dynamism, thus confirming the influence of cultural norms. Our findings contribute to HRD practitioners by highlighting the different conflict‐handling style and culture influence will result in different level of acquiescent propensity, trainer evaluations results should be interpreted more carefully and cautiously.     

Personality Traits Predict Smartphone Usage

The present study investigates to what degree individual differences can predict frequency and duration of actual behaviour, manifested in mobile application (app) usage on smartphones. In particular, this work focuses on the identification of stable associations between personality on the factor and facet level, fluid intelligence, demography and app usage in 16 distinct categories. A total of 137 subjects (87 women and 50 men), with an average age of 24 (SD = 4.72), participated in a 90‐min psychometric lab session as well as in a subsequent 60‐day data logging study in the field. Our data suggest that personality traits predict mobile application usage in several specific categories such as communication, photography, gaming, transportation and entertainment. Extraversion, conscientiousness and agreeableness are better predictors of mobile application usage than basic demographic variables in several distinct categories. Furthermore, predictive performance is slightly higher for single factor—in comparison with facet‐level personality scores. Fluid intelligence and demographics additionally show stable associations with categorical app usage. In sum, this study demonstrates how individual differences can be effectively related to actual behaviour and how this can assist in understanding the behavioural underpinnings of personality.

The (In)visibility of Psychodiagnosticians' Expertise

This study investigates decision making in mental health care. Specifically, it compares the diagnostic decision outcomes (i.e., the quality of diagnoses) and the diagnostic decision process (i.e., pre‐decisional information acquisition patterns) of novice and experienced clinical psychologists. Participants' eye movements were recorded while they completed diagnostic tasks, classifying mental disorders. In line with previous research, our findings indicate that diagnosticians' performance is not related to their clinical experience. Eye‐tracking data provide corroborative evidence for this result from the process perspective: experience does not predict changes in cue inspection patterns. For future research into expertise in this domain, it is advisable to track individual differences between clinicians rather than study differences on the group level.

Aims and Exclusivity

If belief has an aim by being a (quasi) intentional activity, then it ought to be the case that the aim of belief can be weighed against other aims one might have. However, this is not so with the putative truth aim of belief: from the first‐person perspective, one can only be motivated by truth considerations in deliberation over what to believe (exclusivity). From this perspective then, the aim cannot be weighed. This problem is captured by David Owens's Exclusivity Objection to belief having an aim (2003). Conor McHugh (2012; 2013) has responded to this problem by denying the phenomenon of exclusivity and replacing it with something weaker: demandingness. If deliberation over what to believe is characterised by demandingness and not exclusivity, this allows for the requisite weighing of the truth aim. I argue against such a move by suggesting that where non‐evidential considerations play a role in affecting what we believe, these considerations merely change the standards required for believing in a particular context, they do not provide non‐evidential reasons for forming or withholding belief, which are considered as such from the deliberative perspective. Exclusivity thus remains, and so too does Owens's objection.

HO-GDINA模型的EM算法参数估计

Generalized DINA Model(G-DINA)为认知诊断模型提供了一个一般性的理论框架,而高阶诊断模型不仅能描述被试的总体水平,还能描述被试对属性的掌握情况(微观的认知状态)以及被试掌握属性与能力的关系,提供更丰富的信息。如果能把这两者结合起来,可能对实际诊断工作的操作有较大帮助。文章首先对考虑高阶结构的整合性模型——HO-GDINA模型的形式进行讨论,探讨其参数估计EM算法的实现,并用模拟过程对模型的估计精度进行研究,结果验证了HO-GDINA的EM算法的正确性,并且说明该算法对该模型有较高估计精确度。然后用饱和模型在约束条件下的特殊形式HO-DINA模型对"分数减法"这一经典数据进行EM算法参数估计和具体分析,展示了HO-GDINA在实际情况中的具体使用,并与de la Torre之前用MCMC估计算法得到的研究结果做比较,基本一致,进一步表明HO-GDINA模型的参数估计EM算法在实际情境中的特殊形式下仍然适用。
