Two experiments provide further information on the effects of divided attention (DA) on encoding and retrieval processes. The first experiment examined the effects of decision and motor difficulty of a concurrent reaction time task. A calibration analysis was used in the second experiment to test the hypothesis that shifting attentional emphasis away from encoding to the secondary task reduces the level of processing the to-be-remembered items receive. Overall, the results confirm and extend the conclusions of Craik, Govoni, Naveh-Benjamin, and Anderson (1996) and Naveh-Benjamin, Craik, Guez, and Dori (1998), by pointing to clear differences between encoding and retrieval processes: Encoding is affected by simultaneous task demands, especially those associated with "central" resources involved in conscious decision making, whereas retrieval is obligatory in that it is largely immune to the effects of simultaneous demands. The results of the calibration analysis suggest that one reason for the poorer memory performance as a result of DA at encoding is a qualitative shift to less deep, elaborative strategies. 相似文献

Humans prefer curved visual objects 总被引:1,自引:0,他引:1
People constantly make snap judgments about objects encountered in the environment. Such rapid judgments must be based on the physical properties of the targets, but the nature of these properties is yet unknown. We hypothesized that sharp transitions in contour might convey a sense of threat, and therefore trigger a negative bias. Our results were consistent with this hypothesis. The type of contour a visual object possesses--whether the contour is sharp angled or curved--has a critical influence on people's attitude toward that object. 相似文献

Very first impressions 总被引:1,自引:0,他引:1
First impressions of people's personalities are often formed by using the visual appearance of their faces. Defining how quickly these impressions can be formed has critical implications for understanding social interactions and for determining the visual properties used to shape them. To study impression formation independent of emotional cues, threat judgments were made on faces with a neutral expression. Consequently, participants' judgments pertained to the personality rather than to a certain temporary emotional state (e.g., anger). The results demonstrate that consistent first impressions can be formed very quickly, based on whatever information is available within the first 39 ms. First impressions were less consistent under these conditions when the judgments were about intelligence, suggesting that survival-related traits are judged more quickly. The authors propose that low spatial frequencies mediate this swift formation of threat judgments and provide evidence that supports this hypothesis. 相似文献

Divided attention at encoding is well known to have adverse effects on episodic memory performance (e.g., Naveh-Benjamin & Greg, 2000). This article attempts to determine whether these effects are a result of the interruption of encoding of associative information among the components of an episode. Five experiments, using different types of episodes and episodes components, were conducted. Participants studied information under either full or divided attention and were then tested on their memory for both the episodes' components and the associations between them. Divided attention did not produce a differential deficit in memory for associative information; memory for the components suffered to the same degree as memory for the associations among the components. The cause of the divided-attention effect at encoding lies somewhere other than in the associative processes that are engaged. 相似文献

This study further tested an associative-deficit hypothesis (ADH; M. Naveh-Benjamin, 2000), which attributes a substantial part of older adults' deficient episodic memory performance to their difficulty in merging unrelated attributes-units of an episode into a cohesive unit. First, the results of 2 experiments replicate those observed by M. Naveh-Benjamin (2000) showing that older adults are particularly deficient in memory tests requiring associations. Second, the results extend the type of stimuli (pictures) under which older adults show this associative deficit. Third, the results support an ADH in that older adults show less of an associative deficit when the components of the episodes used are already connected in memory, thereby facilitating their encoding and retrieval. Finally, a group of younger adults who encoded the information under divided-attention conditions did not show this associative deficit. 相似文献

The study examined the effect of several personal and situational variables upon stayers' intention to leave, subsequent to the departure of a coworker. These effects were hypothesized to be mediated by the stayers' evaluation of outcomes of the departure. Police officers filled questionnaires prior to and within one month subsequent to turnover of a coworker. The theoretical model was tested via hierarchical multiple regression. Negative and positive evaluations were independent: They were differentially associated with the predictor variables and they varied in their effect upon the criterion measure. The mediation hypothesis was not supported; the negative evaluation of departure outcomes was indeed predicted by the independent variables but it was not associated with the intention to leave subsequent to a coworker's departure. Positive evaluation, on the other hand, was not predicted by the independent variables but was significantly and positively correlated with the criterion measure. Contrary to the hypothesis, stayers who perceive coworkers' departure as more positive show a stronger tendency to leave. 相似文献

The general hypothesis that students self-selecting themselves for different occupational fields differ in relevant values and interests was tested for specializations within engineering. Industrial engineers were found to be different in work values and in their image of their subfield from students of other engineering specializations. The study concludes that in terms of type of student selecting engineering, the profession cannot be treated as an undifferentiated entity. It is suggested that in future research engineering students may be regarded as relatively homogenous with respect to work values only if their area of specialization is duly considered. 相似文献

The Applicability of the Door-in-the Face Technique when Established Behavioral Customs Exist 总被引:1,自引:0,他引:1
The applicability of the door-in-the-face technique was tested in a monetary donation context where established behavioral standards exist, and where the target person has standards by which to judge the legitimacy of the solicitor's demand. Based on the proposition that exaggerated initial requests might discredit the solicitor and thereby halt the give-and-take process, it was expected that (a) with legitimate initial requests, the probability of compliance with a request would be greater when preceded by a larger request than if presented alone; and that (b) with illegitimate initial requests, the probability of compliance with a second request would be smaller when preceded by a larger request than if presented alone. On the national collection day for the Association for the Rehabilitation of the Mentally Handicapped, 400 subjects were asked to contribute IL 10, 15, or 20. In the experimental groups, these amounts were preceded with requests for larger sums which were judged previously by a pretest to be considered legitimate or illegitimate. In the control groups, subjects were asked to contribute the same amounts, but no larger amounts were first requested. The replicability of the door-in-the-face technique has been proven with requests for which established customs exist. However, the technique was only effective with legitimate initial requests. With initial requests that were previously judged as unreasonable, the technique had a "boomerang effect" and suppressed compliance. 相似文献
