线索有效性对儿童返回抑制的影响

采用通常的线索—靶子实验,来考察不同的线索有效性对儿童返回抑制的影响。所用的外源性线索分高有效性、低有效性和非信息性三类。儿童被试在实验中的任务为觉察圆形光点后即按键反应,记录反应时。结果表明,7岁、9岁和11岁儿童在高有效性和非信息性线索条件下均出现返回抑制;但7岁和9岁儿童在低有效性线索条件未出现返回抑制,而11岁儿童则出现。这些儿童的实验结果有别于成人。结果提示,7岁、9岁和11岁儿童的返回抑制是在外源性线索的作用下自动出现的,具有反射性质;但7岁和9岁儿童的返回抑制仍受线索有效性的制约,而11岁儿童返回抑制的发展已不受线索有效性的影响。     

儿童心理理论能力中的情绪理解

情绪理解是儿童心理理论能力中的一个重要组成部分,它在人们的社会交往中具有不容忽视的作用。按Tager-Flusber和Sullivan提出的心理理论两成分模型,它属于心理理论的社会知觉成分,先于社会认知成分出现;但是随着儿童年龄的增长,社会知觉成分与社会认知成分越来越难以分离。情绪理解可分为几个不同的层次：简单情绪的理解;和愿望、信念有关的情绪理解;复杂情绪的理解;情绪调节。该文综述了近20年来心理理论中有关儿童情绪理解的研究,对该领域的研究在方法上和内容上提出了可能的发展方向。

Driving Under the Influence (of Stress): Evidence of a Regional Increase in Impaired Driving and Traffic Fatalities After the September 11 Terrorist Attacks

ABSTRACT— Did the September 11 terrorist attacks elicit a subsequent increase in traffic fatalities? Gigerenzer (2004) argued that decreases in flying and increases in driving in the 3 months after the attacks led to 353 "surplus" traffic fatalities. We applied a more systematic analysis to the same data and found no evidence of a significant increase in miles driven or of a significant increase in traffic fatalities. However, we did find evidence for a regional effect of the attacks on driving behaviors. We hypothesized that geographic proximity to the attacks increased stress, which in turn decreased driving quality. Our analyses revealed that in the last 3 months of 2001, the Northeast exhibited a significant increase in traffic fatalities, as well as a significant increase in fatal accidents involving an alcohol- or drug-related citation. Increased stress related to physical proximity to the attacks may explain the increase in traffic fatalities.

Distributional analyses in auditory lexical decision: Neighborhood density and word-frequency effects

In the present article, the effects of phonological neighborhood density and word frequency in spoken word recognition were examined using distributional analyses of response latencies in auditory lexical decision. A density × frequency interaction was observed in mean latencies; frequency effects were larger for low-density words than for high-density words. Distributional analyses further revealed that for low-density words, frequency effects were reflected in both distributional shifting and skewing, whereas for high-density words, frequency effects were purely mediated by distributional skewing. The results suggest that word frequency plays a role in early auditory word recognition only when there is relatively little competition between similar-sounding words, and that frequency effects in high-density words reflect postlexical checking.     

Preserved visual representations despite change blindness in infants

Combining theoretical hypotheses of infant cognition and adult perception, we present evidence that infants can maintain visual representations despite their failure to detect a change. Infants under 12 months typically fail to notice a change to an object's height in a covering event. The present experiments demonstrated that 11‐month‐old infants can nevertheless maintain a viable representation of both the pre‐ and post‐change heights despite their ‘change blindness’. These results suggest that infants, like adults, can simultaneously maintain multiple representations, even if they do not optimally use them.     

Marital satisfaction in covenant versus standard marriages: Is there a difference?

After the rapid increase of the American divorce rate in the late 20th century, one of the most conspicuous efforts of the marriage movement in the 1990s that was used to increase marital stability was the legislation of the covenant marriage license, a more restricted marriage license issued in three different states of the U.S. To investigate the marital life of newlywed covenant versus standard couples, a large-scale 5-year couple study was conducted between 1998 and 2003 in Louisiana. The present study uses this large-sample, multiple-wave, multiple-group dyadic dataset to examine differences in co-development and divorce rates in 297 covenant and 380 standard mixed-sex couples using a multiple group growth curve modeling and survival analysis. We examined differences in marital trajectories between covenant and standard couples as well as between husbands and wives in each marital group. The results show (1) that the couples in both groups experienced, on average, declines in marital satisfaction, and such a decline was slower in covenant husbands than their wives as well as those in standard marriages, and (2) that co-development in marital satisfaction was more prominent in standard marriages than in covenant marriages, meaning standard couple's marital satisfaction declined at a more similar rate than that of covenant couples. We provide possible explanations and discuss practical implications.     

在不同注意定向条件下是否出现返回抑制的知觉优先

返回控制中的知觉优先是指相对于非线索化位置,线索化位置的刺激被优先知觉到的现象。研究采用时序判断方法对不同注意定向下返回抑制的知觉优先现象进行了两个实验。实验１采用连续线索化的安排,发现当注意从线索化位置移开后知觉优先仍然存在;实验２采用同时呈现双线索的安排发现知觉优先也存在。     

关于短时记忆中范畴群集的定位实验

本研究通过对短时记忆的编码或提取阶段进行注意分散来探讨范畴群集的定位问题。以大学生为被试,应用双作业进行分散注意条件下的记忆实验,并与集中注意条件下的记忆实验进行比较。识记材料均为双范畴词表。结果表现无论在编码还是提取阶段分散注意,都导致范畴群集程度的降低。实验结果不支持认为范畴群集的组织过程仅仅发生在记忆信息加工的某一个阶段的看法,而有利于双重定位观点,即认为范畴群集既与编码阶段有关,也与提取阶段有关。
