儿童心理时间之旅的发展

人类在心理上把自我投射到过去以重新经历过去事件以及把自我投射到未来以预先经历未来事件的能力被称为心理时间之旅。心理时间之旅是认知心理学、认知神经科学、进化心理学、比较心理学、发展心理学等多个学科共同关注的研究领域。目前有关个体心理时间之旅的发展研究表明,心理时间之旅大约出现在儿童3~5岁时。未来有关个体心理时间之旅的发展性研究应从研究范式、研究技术、认知机制、文化差异等方面加以改进。     

儿童行为与心理水平的特质推理的发展

选取4岁组、5岁组、7岁组、10岁组、12岁组儿童和成人共192名(各年龄组32名, 男女各半)为被试, 采用个别测查法考察学前和小学儿童行为与心理水平的特质推理发展。结果表明: (1)4岁时儿童已能进行行为水平的特质推理, 5岁时才能进行心理水平的特质推理, 即使用特质引发规则进行特质推理, 10岁时两者均达到成人水平。(2)4岁、5岁时儿童心理水平的特质推理显著落后于行为水平的特质推理, 至少7岁时两者处于同一水平上。(3)儿童使用概念相似规则而不是情境匹配规则进行行为预测。(4)4岁儿童不使用简单效价规则进行行为预测, 5岁及以上儿童使用简单效价规则, 但他们是在区分同一特质范畴和不同特质范畴的基础上、在较低的确定程度上使用该规则。     

Characteristics of personally important episodic memories,counterfactual thoughts,and future projections across age and culture

We have limited knowledge as to whether the phenomenological differences between episodic memories, counterfactuals, and future projections show the same pattern across age groups and diverse samples. Here we compared the characteristics of these mental events, reported by younger and older participants in a Turkish (Study 1) and in an American sample (Study 2). In both studies, memories contained more sensory-perceptual-spatial details, were easier to bring to mind, and more specific. Future projections were the most positive, whereas counterfactuals were the least emotionally intense. In Study 1, older participants rated the events more positively and experienced them with more perceptual detail, whereas younger participants reported the future to be more voluntarily rehearsed, important, and central. These age differences did not replicate in Study 2. Overall, phenomenological differences between the events are robust and replicate across diverse samples. However, age differences are more sensitive to cultural or individual differences.     

Expectancy bias mediates the link between social anxiety and memory bias for social evaluation

Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.     

中学生时间洞察力特质与健康行为选择内隐偏好：未来情景性思维的作用

本研究采用经典内隐联想测验任务,研究了现在享乐、现在宿命和未来三种时间洞察力特质中学生的健康行为选择内隐偏好以及未来情景性思维在时间洞察力类型与健康行为选择内隐偏好中的调节作用。结果发现：未来特质中学生的健康行为选择内隐偏好高于现在享乐和现在宿命特质中学生;未来情景性思维水平在中学生时间洞察力类型与健康行为选择内隐偏好的关系中起调节作用,即未来情景性思维显著提高现在享乐和未来特质中学生的健康行为选择内隐偏好,而对现在宿命特质的作用不显著。本研究的发现表明未来时间洞察力特质是中学生选择健康行为的积极因素;未来情景性思维能促进现在享乐和未来时间洞察力特质中学生的健康行为选择内隐偏好。     

The ethics of earthquake prediction

Scientists’ responsibility to inform the public about their results may conflict with their responsibility not to cause social disturbance by the communication of these results. A study of the well-known Brady-Spence and Iben Browning earthquake predictions illustrates this conflict in the publication of scientifically unwarranted predictions. Furthermore, a public policy that considers public sensitivity caused by such publications as an opportunity to promote public awareness is ethically problematic from (i) a refined consequentialist point of view that any means cannot be justified by any ends, and (ii) a rights view according to which individuals should never be treated as a mere means to ends. The Parkfield experiment, the so-called paradigm case of cooperation between natural and social scientists and the political authorities in hazard management and risk communication, is also open to similar ethical criticism. For the people in the Parkfield area were not informed that the whole experiment was based on a contested seismological paradigm.     

Obstructive sleep apnea syndrome: autobiographical memory predicts the course of depressive affect after nCPAP therapy

Although nCPAP therapy has proven to be efficient at removing symptoms of obstructive sleep apnea syndrome (OSAS), recovery from depression frequently remains unsatisfactory. Other studies have shown that recall of autobiographical memories (AM) is a psychological vulnerability marker for depression, and also have shown its predictive power for the course of depression. It is therefore hypothesized that AM also predict the course of depressive affect in OSAS patients. Fifty-four consecutively admitted OSAS patients received standard nCPAP therapy. Specificity of AM assessed at the beginning of treatment was used as a predictor in a regression analysis, and the extent of recovery from depression over a follow-up period of between six to nine weeks served as the criterion variable. The results supported the hypothesis that patients who were able to recall more specific AM in response to positively valenced cue words showed a more substantial recovery from depression. This has important treatment implications.     

Episodic and semantic memory in bilingual and monolingual children

Although bilinguality has been reported to confer advantages upon children with respect to various cognitive abilities, much less is known about the relation between memory and bilinguality. In this study, 60 (30 girls and 30 boys) bilingual and 60 (30 girls and 30 boys) monolingual children in three age groups (mean ages 8.5, 10.5 and 12.5 years) were compared on episodic memory and semantic memory tasks. Episodic memory was assessed using subject-performed tasks (with real or imaginary objects) and verbal tasks, with retrieval by both free recall and cued recall. Semantic memory was assessed by word fluency tests. Positive effects of bilingualism were found on both episodic memory and semantic memory at all age levels. These findings suggest that bilingual children integrate and/or organize the information of two languages, and so bilingualism creates advantages in terms of cognitive abilities (including memory). Some sex differences were also found in episodic memory but not in semantic memory. This episodic memory difference was found with younger children.     

Memory for the Events of Early Childhood

There has been much recent interest in the phenomenon of childhood amnesia, the difficulty most adults have in recalling at least the first 3 years of life. In contrast, it has been shown that infants 18 months of age or less can retain information over long periods. Although there is no agreed-upon explanation of this paradoxical phenomenon, there are proposed biological, cognitive, and social-cognitive explanations. Distinguishing among these accounts involves investigating both adults' memories for childhood events and the mnemonicabilities of young children. These studies may not only reveal the reason why our earliest years are shrouded from us as adults, but also shed light on the memory processes that allow us a rich representation of the remainder of our personal past.     

A Different Look at Assessment Centers: Views of Assessment Center Users

This study aims to shed light on possible problems of assessment center users and designers when developing and implementing assessment centers. Semi-structured interviews with a representative sample of assessment center users in Flanders revealed that, besides a large variability in assessment center practice, practitioners experience problems with dimension selection and definition, exercise design, line/staff managers as assessors, distinguishing between observation and evaluation, and with the content of assessor training programs. Solutions for these problems are suggested.
