It has long been debated whether or not a salient stimulus automatically attracts people’s attention in visual search. Recent findings showed that a salient stimulus is likely to capture attention especially when the search process was inefficient due to high levels of competition between the target and distractors. Expanding these studies, the present study proposes that a specific nature of visual search, as well as search efficiency, determines whether or not a salient, task-irrelevant singleton stimulus captures attention. To test this proposition, we conducted three experiments, in which participants performed two visual search tasks whose underlying mechanisms are known to be different: orientation-feature search and Landolt-C search tasks. We found that color singleton distractors captured attention when participants performed the orientation-feature search task. The magnitude of this capture effect increased as search efficiency decreased. On the contrary, the capture by singleton distractors was not observed under the Landolt-C search task. This differential pattern of capture effect was not due to differences in search efficiency across the search tasks; even when search efficiency was controlled for, stimulus-driven capture of attention by a salient distractor was found only under the feature search. Based on these results, the present study suggests that in addition to search efficiency, the nature of search strategy and the extent to which attentional control is strained play crucial roles in observing stimulus-driven attentional capture in visual search. 相似文献

本研究探讨了汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响.实验结果表明逆意排列的汉字词处于不同方位(正位、左右倾斜90°、倒位),对汉字词的念读速度产生明显影响.汉字词处于正位时,念读速度最快;其次是处于左斜与右斜90°;对汉字词的念读速度最慢而准确性最低是处于倒位时(汉字词颠倒).汉字词无论是顺意排列或是逆意排列,正位结果均明显优于倒位结果;但汉字词在倒位顺意排列条件下,结果优于正位逆意排列的结果,这表明,字词间的意义联系的作用大于字词方位的作用. 相似文献

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects. 相似文献

Space usage in drawings is an important element that provides useful information about the drawer’s level of energy and psychological status. In this paper, we delineate the development of a computer system to objectively and quantitatively evaluate the space usage using regression models and computer analysis. We formulate regression models whose dependent variables are the grades and the ranks of space usages. We emphasize the contribution of the area of the painted convex hull in explaining the grades and ranks, which we propose as an independent variable. All possible independent variables including the area of painted regions and the number of colors used are evaluated by the computer algorithms developed in this study. We measure the validity of the system for evaluating grades and ranks. As an application to a real case, the system has been used to investigate the relationship between the space usage and the level of dementia. 相似文献

This study examined the associations of specific personality traits and general personality dysfunction in relation to the presence and severity of Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM–IV]; American Psychiatric Association, 1994) personality disorders in a Dutch clinical sample. Two widely used measures of specific personality traits were selected, the Revised NEO Personality Inventory as a measure of normal personality traits, and the Dimensional Assessment of Personality Pathology-Basic Questionnaire as a measure of pathological traits. In addition, 2 promising measures of personality dysfunction were selected, the General Assessment of Personality Disorder and the Severity Indices of Personality Problems. Theoretically predicted associations were found between the measures, and all measures predicted the presence and severity of DSM–IV personality disorders. The combination of general personality dysfunction models and personality traits models provided incremental information about the presence and severity of personality disorders, suggesting that an integrative approach of multiple perspectives might serve comprehensive assessment of personality disorders. 相似文献

《老子》书大致从战国晚期就开始以道经为上篇、德经为下篇,到王弼为《老子》作注时,《老子》的篇次和章句划分应该初步稳定。唐陆德明采用王弼注为《老子》作音义,并以道、德作为上、下篇题,以后又经历了长时期的流传变化,至明代后期或清代,今传王弼本的篇章结构逐渐固定下来。 相似文献
