The Relationship of Reliability and Validity of Personality Tests to Frame‐of‐Reference Instructions and Within‐Person Inconsistency

The efficacy of both frame‐of‐reference (FOR) instructions and a measure of within‐person inconsistency in predicting grade point average was investigated. The IPIP Big Five personality questionnaire was given to 329 students with generic instructions and ‘at school’ FOR instructions. The Wonderlic Personnel Test was also administered. A measure of within‐person inconsistency was created based on the standard deviations of responses to items within the same Big Five dimension. The validity of conscientiousness was greater when FOR instructions were given. The measure of within‐person inconsistency provided incremental validity over that of conscientiousness and cognitive ability. Additionally, within‐person inconsistency moderated the relationship between conscientiousness and performance for the participants without the FOR instructions. Practical implications are discussed.     

关于维特根斯坦《杂评》一书的翻译

前几天偶然在《世界哲学》今年第一期上看到徐志跃先生的"维特根斯担《杂评》的汉译及其宗教思想"一文,得知他对我译的《杂评》一书提出许多批评,十分高兴,也非常感谢!     

Event valence and estimates of own, average person's, and randomly chosen person's risk

People typically believe they have a lower likelihood of experiencing negative events and a greater likelihood of experiencing positive events than does the average person. This effect is greater for negative than positive events. It has been proposed that this is a by-product of a tendency for estimates of the average person's likelihood to increase with the size of the group concerned. If so, event valence should affect estimates of the average person's likelihood, but not estimates of one's own likelihood or estimates of the likelihood of a person selected at random. These predictions were tested for a single event using a student sample (N = 113). Results were not in accord with the proposal. An explanation in terms of motivational processes is offered instead.     

'Silent' priming of translation-dependent LTP by ß-adrenergic receptors involves phosphorylation and recruitment of AMPA receptors

The capacity for long-term changes in synaptic efficacy can be altered by prior synaptic activity, a process known as "metaplasticity." Activation of receptors for modulatory neurotransmitters can trigger downstream signaling cascades that persist beyond initial receptor activation and may thus have metaplastic effects. Because activation of β-adrenergic receptors (β-ARs) strongly enhances the induction of long-term potentiation (LTP) in the hippocampal CA1 region, we examined whether activation of these receptors also had metaplastic effects on LTP induction. Our results show that activation of β-ARs induces a protein synthesis-dependent form of metaplasticity that primes the future induction of late-phase LTP by a subthreshold stimulus. β-AR activation also induced a long-lasting increase in phosphorylation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) GluA1 subunits at a protein kinase A (PKA) site (S845) and transiently activated extracellular signal-regulated kinase (ERK). Consistent with this, inhibitors of PKA and ERK blocked the metaplastic effects of β-AR activation. β-AR activation also induced a prolonged, translation-dependent increase in cell surface levels of GluA1 subunit-containing AMPA receptors. Our results indicate that β-ARs can modulate hippocampal synaptic plasticity by priming synapses for the future induction of late-phase LTP through up-regulation of translational processes, one consequence of which is the trafficking of AMPARs to the cell surface.     

The Relation Between Eating- and Weight-Related Disturbances and Depression in Adolescence: A Review

Depression often emerges during adolescence and persists into adulthood. Thus, it is critical to study risk factors that contribute to the development of depression in adolescence. One set of risk factors that has been recently studied in adolescent depression research is eating- and weight-related disturbances (EWRDs). EWRDs encompass negative cognitions related to one’s body or physical appearance, negative attitudes toward eating, and unhealthy weight control behaviors. However, there have been no comprehensive reviews of EWRDs and depression research that are contextualized within developmental frameworks of adolescent depression. Thus, this review will summarize research findings on the relation between EWRDs and depression in adolescence using a cognitive vulnerability developmental framework. First, a brief overview of epidemiological findings on depression is provided in order to highlight the importance of examining depression in adolescence. Second, a cognitive vulnerability developmental framework that can be used to conceptualize depression in adolescence is described. Next, theories and findings on EWRDs and depression in adolescence are summarized within this framework. Research limitations and suggestions for future research are provided. Finally, implications of this review related to the assessment, intervention, and prevention of depression in adolescence are provided.     

Éléments de validité de contenu des questionnaires d’intérêts Inforizon et exploration de dimensions sous-jacentes à l’organisation de facteurs d’intérêts

This study concerns the confirmatory factorial analysis test of the correspondence between a theory of the definition of the interests proposed in a list of factors and the responses from 5304 subjects in two self-evaluation questionnaires. The questionnaires were provided by a professional advice and support IT tool, Inforizon. It allows the user to explore professional worlds, according to his particular interests. The principles at work are designed to overcome difficulties regularly encountered in the use of interest scores. The empirical structure of the responses to the questionnaires appears to be compatible with the definition model. A second stage is the exploratory research of the explanatory and parsimonious dimensions of the approximately circular organisation of the interest factors.

教师和家长关于儿童入学准备观念的调查研究

本研究对218名家长和370名教师进行了问卷调查。从身体和运动发展、情绪和社会性发展、学习方式、言语发展、认知发展和一般知识基础、家庭6个维度,考察了家长和教师对儿童入学准备的看法,并比较了家长、幼儿教师和小学教师对儿童入学准备观念的差异。结果发现:(1)整体上看,家长、幼儿教师和小学教师最重视身体健康、注意力、教养方式、自信心、学习兴趣、会听课等方面的问题;(2)幼儿教师和小学教师有关儿童入学准备的观念比较接近,而小学教师相对重视服从权威、父母教育程度、文明礼貌、自我中心和表达能力等方面的问题;幼儿教师相对重视抗挫折能力、亲子关系、学习态度、自我控制、身体健康等方面的问题;(3)家长与教师的观念在整体上存在显著差异。
