The effects of perceptual grouping/segregation of targets and distractors by means of colour on positive and negative priming were examined in two experiments. In Experiments 1 and 2 we examined whether grouping of target and distractors by means of common colour in the prime display affected positive and negative priming, or whether these effects depend on prime–probe contextual similarity in colour. In addition, we examined the effects of the predictability of target colour in the prime and the probe displays across the experiments using mixed (Experiment 1) or blocked procedures (Experiment 2). The pattern of results was similar in both experiments, indicating that the positive priming effect was determined by target repetition and enhanced by perceptual segregation of target from distractors in the prime display. The negative priming effect was determined by grouping the target and distractors by common colour in the prime display. The results of the present experiments are consistent with inhibition-based models of negative priming. 相似文献

Items held in working memory (WM) can automatically bias attention when they reappear in visual displays. Recent evidence, however, suggests that WM biases of attention may be reduced under certain conditions, for example with increasing memory load. We employed a dual task paradigm to investigate how WM biases are affected by dynamic updating of memory contents. 1-back and 2-back versions of a memory task with colour stimuli were interrupted at intervals by an unrelated visual search task. Reappearance in the search display of the item that was currently active in WM guided attention, while suppressed or inactive items did not. We conclude that the rapid updating of memory contents facilitates the shifting of memory representations into different activity states on a moment-to-moment basis. The finding is consistent with models that propose that only one item can be “active” in WM at any one time to guide attention. 相似文献

Four experiments explored the effect of cognitive load on the time course of top-down guidance of attention from working memory (WM). Observers had to search for a target presented among several distractors, with the target and distractor stimuli embedded inside different objects. On half of the trials, one of the distractor objects was cued by a matching item held in WM. When a single item was maintained in memory, search performance was impaired relative to a neutral baseline, where the memory and search displays did not match. These effects of WM on subsequent search were reduced by including a verbal suppression task during the WM and search displays, and by varying the WM load. The degree of competition for resources in WM is a key factor in determining the time course and magnitude of the interaction between WM and visual selection. 相似文献

This study presents the validity and reliability analysis of a questionnaire that assesses the importance of some general job features, for the diagnosis of youths' expectations and priorities concerning a future job. The results show an 8-factor structure with a very good fit to the theoretical structure of the questionnaire, and reliability for the entire questionnaire and for the factor sub-scales is also quite satisfactory. The analysis of the sub-scale scores reveals that youths' most important factor is Self-actualization, whereas the Manual dimension is the least important one. 相似文献

The aim of the present study is to elaborate an instrument (CSM-P), valid for victims and aggressors, to assess satisfaction of individuals participating in a penal mediation program (VOM). The instrument was administered to a sample of 213 subjects, randomly chosen from the pool of participants in a VOM program of Catalonian Justice Department. Data analysis of the questionnaire shows an internal consistency of .88 (Cronbach's alpha). The dimensionality of the questionnaire is structured in a single factor that accounts for 61.45% of the variance. The instrument has proven its utility for assessing the satisfaction of the participants in a penal mediation program. Validation of the instrument in similar populations should be performed and it should be adapted to other contexts where assessing user satisfaction in a mediation program is necessary. 相似文献

The purpose of this study was to explore the expectation that, in conversations between unacquainted men and women, men would disclose more than women and would create a positive impression in so doing. In 8-min, relatively unstructured conversations, both men and women (N=301) perceived themselves and their partners as disclosing approximately the same amount. For both sexes, the more their partners disclosed, the more favorably they rated their partners on social attractiveness and positive attributes. Moreover, both sexes believed that the more they disclosed themselves, the more positively their partners evaluated them. However, the strength of this relationship was significantly stronger for men than for women. Neither sex conformed to the expectation that men should disclose more, but both may have believed to some extent that their partners were evaluating them in accord with this expectation. 相似文献

Recently, it has been shown that patients with visual extinction can show enhanced awareness of contralesional stimuli that match the contents of working memory [Soto, D., & Humphreys, G.W. (2006). Proceedings of the National Academy of Sciences, USA, 103, 4789–4792]. Here we investigate whether these effects extend to cases where the working memory cue is verbal rather than visual (Study 1), and we show that non-spatial cues can overcome problems in spatial disengagement in patients, and this can affect the first eye movement made in search (Study 2). We discuss the implications of the data for understanding the relations between the cueing of attention from visual and conceptual information held in working memory and the cueing of spatial attention, and for understanding the relations between non-spatial and spatial biases in selection. 相似文献

This study aimed to analyse the effect of retention intervals on associative and thematic false memories. Two experiments, using two types of critical items that were either associatively or thematically related to studied material, were conducted. In both experiments, one group of participants performed a recognition test immediately after the presentation of lists, and another group performed the task one week later. In Experiment 1, the recognition test consisted of pairs of items with four response alternatives (both items had been presented, only the left item had been presented, only the right item had been presented or none of the items had been presented). Critical items were also manipulated so that they were either presented in or absent from the list. In Experiment 2, a standard recognition test that differed in the mode of presentation was used: self-paced or speeded response. Both experiments showed that associative critical items were more recognised than thematic critical items in the immediate condition. However, whereas associative critical items decayed after a one-week delay, thematic critical items were similarly recognised at both retention intervals. The findings of the present study suggest that each type of process – associative and thematic – behave differently over time. 相似文献
