生命意义感获取的心理机制及其影响因素

生命意义感体验对个体身心健康有重要的影响,其相关研究也已开始受到心理学各个领域的广泛关注。生命意义感获得与维持的理论研究主要是包括意义感层次模型、意义感构建模型及意义感维持与流动模型。大五人格、心理模拟、积极/消极情绪和亲社会行为是影响个体生命意义感体验的主要因素。未来研究要进一步探讨生命意义感产生的影响因素,完善相关的理论模型,并要从时间序列的角度探讨意义感的产生过程,并对生命意义感获得及维持的跨文化差异进行探讨。     

The rise and fall of the Pacquiao Effect: Contrastive priming and national identification

We demonstrate in a series of field and controlled experiments that assimilative and contrastive priming effects can be observed in the pattern of self‐concept change in response to a major cultural event. Study 1 used the brief implicit association test (BIAT) to measure national identification of Filipinos online across a period of time that encompassed a national sporting event. The pattern of scores support the hypothesis that while people who were ambivalent about identifying with Filipino concepts exhibited an assimilation effect (i.e. a slight rise in identification after the fight), people who already highly identified with being Filipino experienced a contrast effect (i.e. a slight drop in identification). Study 2 replicated this result five months later with a new sample and ruled out several possible alternative hypotheses. A subsequent controlled experiment and a qualitative investigation consistently supported the hypothesis that the pattern observed in the previous studies is more consistent with assimilative and contrastive priming effects rather than disidentification.     

A mixture hierarchical model for response times and response accuracy

In real testing, examinees may manifest different types of test‐taking behaviours. In this paper we focus on two types that appear to be among the more frequently occurring behaviours – solution behaviour and rapid guessing behaviour. Rapid guessing usually happens in high‐stakes tests when there is insufficient time, and in low‐stakes tests when there is lack of effort. These two qualitatively different test‐taking behaviours, if ignored, will lead to violation of the local independence assumption and, as a result, yield biased item/person parameter estimation. We propose a mixture hierarchical model to account for differences among item responses and response time patterns arising from these two behaviours. The model is also able to identify the specific behaviour an examinee engages in when answering an item. A Monte Carlo expectation maximization algorithm is proposed for model calibration. A simulation study shows that the new model yields more accurate item and person parameter estimates than a non‐mixture model when the data indeed come from two types of behaviour. The model also fits real, high‐stakes test data better than a non‐mixture model, and therefore the new model can better identify the underlying test‐taking behaviour an examinee engages in on a certain item.     

检验的临界值：真伪差距多大才能辨别？ ——评《不同条件下拟合指数的表现及临界值的选择》

Hu和Bentler（1998,1999）通过模拟研究推荐结构方程模型拟合指数临界值后,受到不少批评和质疑。此后有关拟合指数的研究重点不再是推出新的临界值标准。郭庆科等人的文章《不同条件下拟合指数的表现及临界值的选择》,仿照Hu和Bentler的做法,通过模拟研究推荐新的拟合指数临界值标准。本文旨在揭示这种做法的错误所在。用简单的Z检验,说明检验的临界值是不能通过模拟研究确定的。通过将一个特定真模型的众多错误模型分类,说明结构方程分析中真模型与错误模型差距的多样性,无法通过模拟一对真伪模型来代表。讨论了统计检验的本质和确定临界值的逻辑,还谈到应当从哪些角度检验和评价结构方程模型     

Remembering versus knowing during face recognition in unilateral temporal lobe epilepsy patients with or without hippocampal sclerosis

Recognition memory involves knowing an item was learned (familiarity) and remembering contextual details about the prior learning episode (recollection). We tested three competing hypotheses about the role of the hippocampus in recollection and familiarity. It mediates either recollection or familiarity, or serves both processes. We further tested whether the left temporal lobe mediates recollection and the right temporal lobe familiarity (modes of processing view), or whether the two temporal lobes mediate remembering material specifically (material specificity view). We investigated 24-h face recognition using the "remember-know" procedure. We studied 23 left and 24 right temporal lobe epilepsy (LTLE/RTLE) patients with and without hippocampal sclerosis (HS+/HS-) and 31 healthy participants. HS+ patients made fewer know responses than HS- patients or healthy participants. RTLE was related to fewer remember responses than LTLE. Our results suggest the hippocampus has a critical role in familiarity. Further, our findings support the material specificity hypothesis of laterality.     

Multiple trajectories of physical aggression among adolescent boys and girls

Latent growth mixture modeling was used to identify discrete patterns of physical aggression from Grades 7 to 11 among a sample of 1,877 youth. Four trajectory classes adequately explained the development of physical aggression in both boys and girls: Low/No Aggression; Persistent High Aggression; Desisting Aggression, characterized by decreasing risk throughout adolescence; and Adolescent Aggression, characterized by low early risk that increases until Grade 9, levels out, and then declines in late adolescence. Girls were less likely than boys were to be in any trajectory besides the Low/No Aggression trajectory. Parental supervision, deviant peer association, academic orientation, impulsivity, and emotional distress at Grade 7 were all strongly associated with trajectory class membership. These associations did not differ by gender. These findings strongly suggest that the processes involved in the development of physical aggression in adolescence operate similarly in boys and girls.     

Scientist versus Practitioner–An abridged meta-analysis of the changing role of psychologists

This study investigated factors of conflicting expectations and roles of the current psychology practitioners, as well as how these factors were associated with the founding principles of the scientist-practitioner model. Data were gathered from ten published journal articles and then interpreted using an abridged meta-analysis methodology. Results revealed: (a) the scientist-practitioner model needs to adapt to survive, preferably with the aim of becoming more versatile; (b) The majority of graduate level clinical psychology training programs are based on a flawed version of the scientist-practitioner model, which renders the training inadequate and ineffective; (c) The identity of clinical psychology should remain firmly grounded in mental health care, and so not encroach on the territory of any other psychological divisions. Implications of these findings and suggestions for psychology practitioners are also discussed.

Linking team resources to work-family enrichment and satisfaction

Work-family scholars now recognize the potential positive effects of participation in one life domain (i.e., work or family) on performance in other life domains. We examined how employees might benefit from team resources, which are highly relevant to the modern workplace, in both work and nonwork domains via work-family enrichment. Using the Resource-Gain-Development model (Wayne, Grzywacz, Carlson, & Kacmar, 2007), we explored how team resources contribute to enrichment and resulting project and family satisfaction. Using multilevel structural equation modeling (ML-SEM) to analyze student data (N = 344) across multiple class projects, we demonstrated that individuals with team resources were more likely to experience both work-to-family and family-to-work enrichment. Further, enrichment mediated the relationship between team resources and satisfaction with the originating domain.
