探索性结构方程建模(ESEM):EFA和CFA的整合

探索性结构方程建模(ESEM)是在测量模型部分使用了类似于EFA模型的SEM.作为一种高级统计方法,ESEM整合了EFA和CFA两种因子分析方法的功能和优点.通过ESEM,研究者既可以灵活地探索因子结构,又可以系统地验证因子模型,为潜变量的关系分析提供更适宜的测量模型.ESEM已经在某些社科领域的研究中得到应用,是一种值得推介的因子分析方法.ESEM的具体应用问题,例如因子旋转方法的选用、测验信度评价等,仍有待探讨.     

猜谜作业中的ERP效应：基于催化范式的证据

运用ERP技术对个体猜谜任务下的顿悟和无顿悟的情况进行探索。结果发现,在300ms-500ms内,有顿悟比无顿悟引发了更负的N300-500成分,激活了大部分脑区;在600ms-1100ms内,有顿悟比无顿悟引发了更正的P600-1100成分,在中央区显示了最强激活。结果表明,N300-500可能反映了定势破除中的认知冲突,P600-1100可能反映了新异联系的形成。     

汉字识别的时间进程：来自字谜任务的ERP证据

通过“学习-测试-判断”的三阶段实验范型, 采用事件相关电位（ERP）技术探讨了猜谜任务中对谜底答案（单个汉字）识别的脑内时程动态变化。结果发现：语义识别与字形识别下,汉字刺激均诱发了明显的N1、P2和N2成分,其中语义识别下的P2波幅表现为更加正性,可能与汉字语义的早期加工有关;随后,300-400ms内,语义识别比字形识别诱发了一个更加正性的ERP成分,该成分可能属于P300成分,反映了对汉字语义的进一步整合加工;最后,500-600ms内,语义识别比字形识别同样诱发了一个更加正性的ERP成分,可能反     

Prediction of treatment outcomes and longitudinal analysis in children with autism undergoing intensive behavioral intervention

Outcome prediction is an important component of treatment planning and prognosis. However, reliable predictors of intensive behavioral intervention (IBI) have not been clearly established. IBI is an evidence-based approach to the systematic teaching of academic, social, verbal, and daily living skills to individuals with autism spectrum disorder. Incorporating longitudinal analysis to IBI outcome studies may help to identify outcome predictors of clinical value. Twenty-four children with autism underwent on average two years of IBI and completed language, daily living skills, cognitive, and motor assessments (Early Learning Accomplishment Profile and the Learning Accomplishment Profile-Diagnostic, 3rd edition) every six months. We used multilevel analysis to identify potential longitudinal predictors including gender, age, intervention intensity, intervention duration, total intervention time, and pre-intervention functioning. Results indicated that total intervention time, pre-intervention functioning, and age caused the greatest increase in goodness-of-fit of the longitudinal multilevel models. Longitudinal analysis is a promising analytical strategy to identify reliable predictors of the clinical outcome of IBI.

Psychiatry and religion: a perspective on meaning

ABSTRACT

A Position Statement on Spirituality and Religion in Psychiatry was issued by the World Psychiatric Association in 2016. Among many recommendations, this statement underscores the need for research on both religion and spirituality in psychiatry, especially on their clinical applications. In this contribution we will put light on the issue of meaning and meaning-making, i.e., an important field for every human, Particularly for individuals suffering from severe mental disorders. After an introduction about meaning in its religious/spiritual dimension, we will describe what needs to be studied in order to get a better knowledge as to how patients cope with meaning, and how they process (in terms of meaning-making) the outburst of a severe mental disorder such as schizophrenia.     

Older age South African persons’ experiences of their needs with cell phone use

This study explored the needs met by cell phone use by older persons. Informants were 52 older South Africans (age range 65 to 89 years, male = 8, female = 44). The older persons completed a visual representation and semi-structured interviews on the needs met by their cell phone usage. Thematic analysis of the data revealed the following needs to be met by their cell phone usage: personal safety, sense of control, managing daily routine, and staying connected with loved ones. Findings are consistent with the propositions of the basic psychological needs theory (BPNT) regarding competence, autonomy, and personal well-being.     

Constructing a positive narrative for African sport consumerism

Sport consumerism is a burgeoning field of practice and serves both the utilitarian and behaviouristic goals. The utilitarian aspects are aligned to derivatives of value generated through the sport consumption effort. Behaviourism in the consumer context suggests a communal narrative, informed through observable actions which, in totality, construe social phenomena. This article applied social exchange theory to understand the utilitarian and behavioural functions sub-served by sport consumer psychology in the African context. An evaluation of literature from regional studies is made and the theory is explored with the view of putting forward research themes for the future.     

Evaluating fit of the Prospective and Retrospective Memory Questionnaire (PRMQ) in a Nigerian adult population

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study.     

Personality and performance in real-world competitions: Testing trait activation of fear of negative evaluation,dispositional reinvestment,and athletic identity in the field

ObjectivesBased on the trait activation principle, researchers have tested whether personality traits are capable of predicting sport performance (under pressure). Typically, however, these investigations followed experimental approaches in the laboratory and only rarely in the field. Accordingly, the purpose of this study was to test for the generalizability of findings gained in these experimental studies and to investigate potential trait activation for real-world performance in competitions. Based on prior studies on the prediction of performance under pressure, the selected personality traits involved fear of negative evaluation, dispositional reinvestment, and athletic identity.DesignPersonality traits were used as predictors for low-pressure and high-pressure basketball free-throw performance.MethodFirst, 53 basketball players completed trait questionnaires. Second, directly prior to performance assessments, participants reported on perceived importance, their somatic and cognitive state anxiety, and confidence. Third, free-throw performance was assessed in a low-pressure condition (i.e., successful free-throw percentage for 30 attempts) and repeatedly in 12 high-pressure conditions within real basketball matches (i.e., successful free-throw percentage for total attempts).ResultsTwo main findings were identified: First, none of the traits predicted performance under low pressure. Second, under high-pressure, only fear of negative evaluation as well as state anxiety were significantly negatively associated with performance in competitions.ConclusionThese results extend existing literature and add applied and ecologically valid empirical support for the relevance of anxiety-related traits (i.e., fear of negative evaluation) and states for performance under pressure in real-world competitions, emphasizing the importance of self-presentational considerations in athletes when the stakes are high.
