Capturing attention when attention blinks   总被引:2,自引:0,他引:2  
Four experiments addressed the question of whether attention may be captured when the visual system is in the midst of an attentional blink (AB). Participants identified 2 target letters embedded among distractor letters in a rapid serial visual presentation sequence. In some trials, a square frame was inserted between the targets; as the only geometric object in the sequence, it constituted a singleton. Capture effects obtained when the AB was most severe and when it was over were compared. There were 3 main results. First, capture occurred even when the AB was crippling, suggesting that a singleton exogenously engaged attention even when processing of a previous target was continuing apace. Second, when the singleton contained the key target feature, capture effects were clearly manifest. Third, even when the singleton did not possess the key target feature, it still succeeded in capturing attention, although the effects were both feeble and fleeting.  相似文献

The active intermodal mapping hypothesis suggests that intentional imitation is mediated by a highly efficient, special-purpose mechanism of actor-centered movement encoding. In the present study, using methods from stimulus-response (S-R) compatibility research, we found no evidence to support this hypothesis. In two experiments, the performance of adult participants instructed to imitate actorcentered spatial properties of head, arm, and leg movements was affected by task-irrelevant, egocentric spatial cues. In Experiment 1, participants imitated using the same side of their bodies as did the model, and performance was less accurate when egocentric stimulus location was response incompatible than when it was response compatible. This effect was reversed in Experiment 2 when participants imitated using the opposite side of their bodies. These findings, in line with general process theories of imitation, imply that intentional imitation is mediated by the same processes that mediate responding to inanimate stimuli on the basis of arbitrary S-R mappings.  相似文献

This is an analysis of practical theology in a parish, responding to organized racism in the local area. The involvement in civil action, as well as the theological aspects of such work are considered and discussed in relation to Scandinavian creation theology. The need for radical practice is discussed in relation to vocation and the love of the neighbor, even when such practice becomes uncomfortable and even threatening.  相似文献

This study aimed to examine the effects and feasibility of a virtual screen-based stress management programme (V-DESSERTS) on inpatients with mental disorders. A single-blinded, pilot randomised controlled trial was conducted in a tertiary hospital in Singapore. Convenience sampling was used and participants were randomised into either the intervention group or the waitlisted control group (WL). The intervention group received individual-based, twice-daily sessions of the programme. Each session comprised education and virtual screen-based relaxation practice. Data were collected through self-reported questionnaires and physiological measures. The intervention group showed a significant increase in perceived relaxation and knowledge in comparison with the WL group. However, inconclusive results were observed on subjective and objective stress. The findings in this study indicated that the V-DESSERTS programme is feasible to be implemented for patients with schizophrenia, depression and bipolar disorders.  相似文献

This study aimed to examine the effects of gambling motives and competitive gambling outcomes on opponent likeability and targeted physical aggression. We hypothesized that (a) losers would perceive their opponents to be less likeable and (b) would be physically more aggressive toward their opponents. Opponent likeability was proposed to mediate the lose–aggression relationship while social gambling motives were proposed to moderate the lose–aggression relationship. Specifically, we expected that losers of competitive gambling situations would engage in greater physical aggression only if they perceived their opponents to be less likeable. In addition, lower perceived opponent likeability would translate into greater targeted physical aggression only if the loser possessed low social motives for gambling. Ninety‐eight undergraduates who self‐identified mostly as recreational gamblers participated in a competitive gambling game. The Hot Sauce Paradigm was adapted as a measure of targeted physical aggression. Results obtained supported our hypotheses. Potential implications and limitations are discussed.  相似文献

Studies examining Black–White mean differences in job satisfaction have provided little clarity regarding whether there are meaningful differences between the two racial/ethnic groups on this job attitude. The present study sought to reconcile prior inconsistent findings via a meta-analytic synthesis of this literature (N = 753,791; K = 63 independent samples from 55 studies) and examined whether moderators explained the observed variability in effects. Using Hedges and Vevea's (1998) random-effects meta-analytic approach, we found that, on average, White workers were slightly more satisfied with their jobs than Black workers (gcorrected = .09; 95% credibility interval = −.21 to .39) and this effect was larger in more nationally representative samples (gcorrected = .24). The substantial true variability around this effect suggests the presence of moderators and the need for caution in interpreting the overall effect as it likely does not generalize across all work settings. Data collection year, geographic location within the U.S., job sector, and measure type were not found to moderate Black–White mean differences in job satisfaction. However, job complexity and sample demographic composition did significantly moderate this relationship. Our results show that the magnitude and direction of Black–White mean differences in job satisfaction are influenced by the context.  相似文献

This multinational study simultaneously tested three prominent hypotheses—universal disposition, cultural relativity, and livability—that explained differences in subjective well‐being across nations. We performed multilevel structural equation modeling to examine the hypothesized relationships at both individual and cultural levels in 33 nations. Participants were 6,753 university students (2,215 men; 4,403 women; 135 did not specify), and the average age of the entire sample was 20.97 years (SD = 2.39). Both individual‐ and cultural‐level analyses supported the universal disposition and cultural relativity hypotheses by revealing significant associations of subjective well‐being with Extraversion, Neuroticism, and independent self‐construal. In addition, interdependent self‐construal was positively related to life satisfaction at the individual level only, whereas aggregated negative affect was positively linked with aggregate levels of Extraversion and interdependent self‐construal at the cultural level only. Consistent with the livability hypothesis, gross national income (GNI) was related to aggregate levels of negative affect and life satisfaction. There was also a quadratic relationship between GNI and aggregated positive affect. Our findings reveal that universal disposition, cultural self‐construal, and national income can elucidate differences in subjective well‐being, but the multilevel analyses advance the literature by yielding new findings that cannot be identified in studies using individual‐level analyses alone.  相似文献

This paper longitudinally studies the emergence and evolution of the first symbolic uses of objects in Mexican children. We observed eight children in triadic interaction with one of their parents and 10 objects in a semi-structured situation at nine, 12, 15 and 18 months old. The children began to use objects symbolically at 12 months, and the duration and frequency increased with age. The highest percentage of the total frequency of symbolic uses, of the four levels identified, was level 1. The frequency of level 4, where two or more symbolic actions occur one after the other, giving rise to ‘symbolic narratives’, increased according to age. These data confirm that knowledge of the rules of canonical uses of objects are the meanings which first symbols base themselves on and that children use the symbolic uses that they are aware of to create ‘symbolic narratives’.  相似文献

During World War II, a total of 48,628 Finnish children were evacuated to Sweden and placed into temporary foster care. We studied the long-term effects of early separation among aging evacuees using a mixed-methods approach. The purpose was to understand how the evacuees experienced the evacuation event from a lifetime perspective and to determine the features of a possible war child syndrome. The evacuees expressed problems related to loss of confidence, detachment or rootlessness, and unworthiness or rejection. Feelings of rejection and unworthiness provoked shame in many of the reports. Our results suggest that support interventions should focus on processing these painful experiences.  相似文献
