Abstract: When two visual targets are presented in rapid succession, perception of the second target is deteriorated if the temporal lag between the two targets is short (0–300 ms). This ‘attentional blink’ (AB) phenomenon has been believed to occur only when the second target is followed by a backward mask or when there is a task switching between two targets. The present study revealed another determining factor for the occurrence of the AB, the presence or absence of a distractor stream. Five experiments examined the effect of possible confounding factors in the extant literature and suggested that the mere presence of a distractor stream affects the processing of targets even when the observers tried to ignore them, resulting in a processing delay. This effect is discussed in a model of AB deficit in terms of decay of the second target's representation. 相似文献

Abstract: Perception of the second of two rapidly presented targets is impaired when the temporal lag between them is short (attentional blink, AB). Previous studies showed two types of AB functions. One is that the performance for the second target has been found to be most impaired at the shortest lag (Lag 1), that is, when the second target appeared directly after the ?rst target. The other is that the performance was not impaired at Lag 1 (Lag 1 sparing). The present study examined whether the task set of observers determines the occurrence of Lag 1 sparing. The experiment revealed that Lag 1 sparing occurred only when the observers were informed of the relationships of target locations. The present results extend the explanation of Lag 1 sparing by attentional gating ( Visser, Zuvic, Bischof, & Di Lollo, 1999 b) and suggest that this gating system is not stimulus‐driven but subject to goal‐directed control. 相似文献

The present study examined associations of neighbourhood crime with residents' social ties and civic participation using multilevel models. We hypothesized that crime is indirectly associated with residents' low civic participation by negatively relating to their acquaintanceship ties because of fear of neighbours. By contrast, we predicted that crime is indirectly related to frequent civic participation by positively associating with more intimate friendship ties as a response to combat external threats. Additionally, we hypothesized that high crime rates in the neighbourhood increases the importance of generalized trust towards others. Therefore, we examined the interaction effects of neighbourhood crime and trust on social ties and participation. The study is based on a postal questionnaire mailed to residents aged between 20 and 69 years, residing in Musashino City and Kiyose City, in Tokyo. Rates of larceny reported by the Tokyo Metropolitan Police Department were used as indices of neighbourhood crime. As hypothesized, our results showed that crime is positively associated with friendship ties and is negatively related to acquaintanceship ties. Through these opposing relationships, crime showed both positive and negative associations with civic participation. Moreover, we found that generalized trust buffered the adverse relationships between crime, broader social ties and participation. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Universal Principles of Human Communication: Preliminary Evidence From a Cross‐cultural Communication Game 下载免费PDF全文

The present study points to several potentially universal principles of human communication. Pairs of participants, sampled from culturally and linguistically distinct societies (Western and Japanese, N = 108: 16 Western–Western, 15 Japanese–Japanese and 23 Western–Japanese dyads), played a dyadic communication game in which they tried to communicate a range of experimenter‐specified items to a partner by drawing, but without speaking or using letters or numbers. This paradigm forced participants to create a novel communication system. A range of similar communication behaviors were observed among the within‐culture groups (Western–Western and Japanese–Japanese) and the across‐culture group (Western–Japanese): They (a) used iconic signs to bootstrap successful communication, (b) addressed breakdowns in communication using other‐initiated repairs, (c) simplified their communication behavior over repeated social interactions, and (d) aligned their communication behavior over repeated social interactions. While the across‐culture Western–Japanese dyads found the task more challenging, and cultural differences in communication behavior were observed, the same basic findings applied across all groups. Our findings, which rely on two distinct cultural and linguistic groups, offer preliminary evidence for several universal principles of human communication. 相似文献

This study examined the relationships between positive emotions and health. Two positive emotions were considered, hope and curiosity, in conjunction with 3 physician-diagnosed disease outcomes: hypertension, diabetes mellitus, and respiratory tract infections. Medical data were abstracted over a 2-year period from 1,041 patient records from a multispecialty medical practice, and emotions were assessed through a mailed questionnaire. Across 3 disease outcomes, higher levels of hope were associated with a decreased likelihood of having or developing a disease. Higher levels of curiosity were also associated with decreased likelihood of hypertension and diabetes mellitus. Results suggest that positive emotion may play a protective role in the development of disease. 相似文献
