Dissertation experiences of doctoral graduates from professional psychology programs

Worldwide, dissertation experiences are acknowledged to be challenging endeavors for students and the faculty members who advise them, and dissertation completion continues to be a concern when seeking to improve overall doctoral graduation rates. Although a number of factors have been associated with completion rates across disciplines, further research is needed within professional psychology graduate programs to understand overall student dissertation experiences. In this USA-based investigation, a mixed-method design was used to examine the experiences of 25 professional psychology doctoral graduates’ dissertation experiences, 12 of which were self-identified as positive and 13 as negative. Participants with positive experiences typically had supportive relationships with their dissertation chairs and committee members, which enhanced their research confidence and professional development. Participants with negative dissertation experiences typically had difficult relationships with dissertation chairs and committee members, which was associated with immediate and long-lasting negative consequences for participants’ professional growth and emotional well-being. The advisory working alliance was stronger for graduates with positive than negative experiences, although research attitudes and self-efficacy beliefs were not different between the two groups.     

性激素对人类择偶偏好的影响

择偶是一种重要的心理、社会和文化现象,婚恋择偶除了会受当下社会文化习俗等人文因素的影响,也受到个体生理机制的影响。本文聚焦热点,从进化心理学的角度阐述性激素对人类择偶偏好的影响。女性的择偶偏好受生理周期激素变化的影响,男性的择偶则会因为体内睾酮含量的不同而发生变化。性激素不仅影响人的心理和行为,还会影响人类择偶决策的神经机制。未来的相关研究应关注生理周期的测定方法、被试的文化背景和个体间的差异等。     

个人主义文化价值观对疫情控制效果的影响及其计算心理机制

COVID-19疫情是一场重大的全球健康危机, 一些国家在控制COVID-19感染和死亡率上存在明显困难。我们提出, 个人主义的文化价值观不利于对疫情的控制。跨文化分析结果显示, 个人主义文化价值观正向预测COVID-19死亡数、每百万死亡数和死亡率, 独立自我建构负向预测疫情前期控制速度。演化博弈模型和跨文化实验进一步提示, 个人主义文化通过增强个体在疫情背景下的死亡恐惧, 增加个体违反疫情管控的流动性倾向, 从而降低了整体疫情控制的效率。我们的结果支持自然-行为-文化协同进化的理论模型, 提示文化对COVID-19病毒传播管控和死亡可能性的影响, 为各国应对全球公共卫生危机提供了重要科学参考。

Typicality effects in picture‐word interference paradigm: An evaluation of the response exclusion hypothesis

The response exclusion hypothesis suggests that the polarity of semantic effects in the picture‐word interference paradigm is determined by the response‐relevant criteria. Semantic interference effects would be observed when semantically related distractor words satisfy the response‐relevant criteria; otherwise, semantic facilitation effects should be found. The purpose of this study was to further evaluate the response exclusion hypothesis by exploring the typicality effects in pictures naming. In two experiments, pictures of objects were named either in the context of verb distractor words with different typicality of passive functions or in the context of adjective distractor words with different typicality of characteristics. Facilitation effects were observed in context of typical verbs and adjectives, while interference effects were observed in the context of atypical verbs and adjectives. Given that neither typical nor atypical distractor words satisfy the response‐relevant criteria to produce noun, these findings are problematic for the response exclusion hypothesis. Role of syntagmatic relationships in lexical retrieval was invoked to explain present findings.     

A Comparison of the Psychometric Properties of the Forced Choice and Likert Scale Versions of a Personality Instrument

The present research investigated if an item response theory (IRT)‐scored forced‐choice personality questionnaire has the same normative data structures as a similar version that uses a 5‐point Likert scale instead. The study was conducted using a sample of 349 training delegates who completed both an IRT‐scored forced‐choice and a normative single‐stimulus version of the questionnaire. Results largely supported the scaling properties, measurement precision, and equivalence of the data structures of the two scoring methods.
