Source recall enhances children's discrimination of seen and heard events

The effects of rehearsing actions by source (slideshow vs. story) and of test modality (picture vs. verbal) on source monitoring were examined. Seven- to 8-year-old children (N = 30) saw a slideshow event and heard a story about a similar event. One to 2 days later, they recalled the events by source (source recall), recalled the events without reference to source (no-source-cue recall), or engaged in no recall. Seven to 8 days later, all children received verbal and picture source-monitoring tests. Children in the source recall group were less likely than children in the other groups to claim they saw actions merely heard in the story. No-source-cue recall impaired source identification of story actions. The picture test enhanced recognition, but not source monitoring, of slide actions. Increasing the distinctiveness of the target events (Experiment 2) allowed the picture test to facilitate slideshow action discrimination by children in the no-recall group.     

Perceptions of ADHD in China and the United States: a preliminary study

College students (n = 226) and teachers (n = 328) in the United States and China completed a 55-item questionnaire examining perceptions of attention deficit/hyperactivity disorder (ADHD) in the two countries. Although a factor analysis yielded somewhat similar structures for the construct of ADHD, many differences emerged as well, with Chinese participants somewhat more attuned to hyperactivity than inattention. Furthermore, presented with a list of potential perceptions of ADHD, there were significant differences by culture in agreement with most of those statements. Thus, it appears that the concept of ADHD may be similar between the cultures, but the many differences warrant further exploration before ADHD is considered to be equivalent in the two countries.     

小学儿童空间物体位置编码（Ⅰ）

采用找物范式研究小学7、9、11岁儿童利用点与点之间的关系对目标物位置进行编码的认知发展。结果表明：两点距离编码和三点共线编码认知成绩的年龄效应显著,9岁组和11岁组儿童的认知成绩显著好于7岁组儿童的认知成绩。两个不同实验任务对儿童认知成绩的影响不同,7岁组儿童两点距离编码认知成绩显著好于三点共线编码认知成绩,9岁组和11岁组两个任务的认知成绩差异不显著。提供编码线索后,认知成绩有了较大的改善。

When days are numbered: calendar structure and the development of calendar processing in English and Chinese.

Unlike English, Chinese uses a numerical system for naming months and days. This study explored whether this difference in naming affects the development of simple calendar calculation. Eight- and 10-year-old children as well as undergraduates in China and the United States were asked to name the day or month that comes a specified time before or after a given day or month. In each age group Chinese speakers primarily used calculation based on calendar names to solve these tasks, while English speakers primarily resorted to reciting the names. The magnitude of these differences was substantial; on difficult tasks Chinese fourth graders performed at speeds comparable to those of English-speaking adults. Implications for models of how linguistic structure affects cognition are discussed.     

Communication behavior and relationship satisfaction among American and Chinese newlywed couples

Most research on couple communication patterns comes from North America and Europe and suggests cross-cultural universality in effects, but emerging studies suggest that couple communication takes different forms depending on the cultural context in which it occurs. The current study addressed this discrepancy by comparing the observed social support behaviors of 50 newlywed American couples and 41 newlywed Mainland Chinese couples, first on mean levels of positivity and negativity and second on behavior-satisfaction associations. Consistent with predictions derived from observational work by Tsai and Levenson (1997), Chinese couples were observed displaying significantly more negative behavior than American couples, even after controlling for relationship satisfaction; the 2 groups did not differ in observed positive behaviors. Tests of the moderating role of culture on behavior-satisfaction associations showed that positivity was significantly related to relationship satisfaction only for American husbands, whereas negativity was significantly associated with relationship satisfaction only for Chinese husbands. We speculate that cultural contexts may influence the display and evaluation of behavior in intimate relationships, suggesting the need for caution when generalizing models and associated interventions to non-Western couples.     

Differential trajectories of age-related changes in components of executive and memory processes

Several studies have demonstrated age-related declines in general executive function and memory. In this study, we examined cross-sectional and longitudinal age effects in more specific cognitive processes that constitute executive function and memory. We postulated that, whereas some components of executive and memory functions would show age differences and longitudinal declines, other specific abilities would be maintained or even improve with repeated testing. In a sample of individuals ≥55 years old from the Baltimore Longitudinal Study of Aging, we found longitudinal declines in inhibition, manipulation, semantic retrieval, phonological retrieval, switching, and long-term memory over a maximum of 14 years follow-up. In contrast, abstraction, capacity, chunking, discrimination, and short-term memory were maintained or even improved longitudinally, probably due in part to repeated testing. Moreover, whereas several different abilities were correlated across participants' cross-sectional performance, longitudinal changes in performance showed more heterogeneous trajectories. Finally, compared with cross-sectional performance, longitudinal trajectories showed better distinction between participants with and those without later cognitive impairment. These results show that longitudinal cognitive aging of executive and memory functions is not a uniform process but a heterogeneous one and suggest that certain executive and memory functions remain stable despite age-related declines in other component processes.

The deviant citizen: Measuring potential positive relations between counterproductive work behaviour and organizational citizenship behaviour

Studies have shown a strong negative correlation between counterproductive work behaviour (CWB) and organizational citizenship behaviour (OCB), and opposite correlations with hypothesized antecedents. Such observed correlations may have been erroneously caused by three measurement artefacts: items measuring absence of CWBs, rather than behaviours that exceed requirements or expectations in OCB scales; supervisory halo; and agreement rather than frequency response format. A new OCB scale, the OCB‐checklist (OCB‐C) was used that did not have these artefacts. Contrary to prior expectations from the literature, positive relations were found between CWB and OCB, and stressors and OCB. Theoretical explanations for positive CWB/OCB relations (demand‐elicited OCB, social loafing, work process problems, rater perceptions and attributions, and aggravated job stress processes) are discussed.     

左右半脸及其位置对面孔吸引力的影响

本研究将拼嵌技术（chimera technique）和融合技术（Morph tech—nique）结合起来,制作新形式的面孔刺激,将“刺激”和“位置”分离并分别操纵,检验了左右半脸及其位置对面孔吸引力的影响。实验结果显示：（1）“刺激”和“位置”都会影响面孔吸引力;（2）“刺激”的影响是直接的,具体表现为右半脸不论呈现在面孔的左侧还是右侧,其吸引力总是高于左半脸的吸引力;（3）“位置”的影响模式较为复杂,具体表现为左右半脸在原始位置呈现时（右丰脸呈现在右侧,左半脸呈现在左侧）,其吸引力总是高于镜像位置。
