We introduce and explore a color phenomenon which requires the prior perception of motion to produce a spread of color over a region defined by motion. We call this motion-induced spread of colordynamic color spreading. The perception of dynamic color spreading is yoked to the perception of apparent motion: As the ratings of perceived motion increase, the ratings of color spreading increase. The effect is most pronounced if the region defined by motion is near 1° of visual angle. As the luminance 相似文献

以汉语单字词为材料,通过颜色来区分目标和分心物,采用过程分离程序,直接探讨了目标激活与分心物抑制和意识、无意识过程之间的关系。结果表明,(1)靶词充当分心物时,不仅意识过程存在的概率降低,无意识过程存在的概率也降低。这一结果说明,在选择性注意任务中,信息是有关还是无关,并不能分离意识和无意识过程;(2)靶词充当目标时,加工水平影响Pc,但不影响Pu,而靶词充当分心物时,加工水平既不影响Pc,也不影响Pu。因此,加工水平能否分离意识和无意识过程,依赖于靶词的作用或信息是否有关 相似文献

In the present study, a metamemory questionnaire was completed by three groups of individuals: memory research psychologists who attended a small international convention on everyday memory processes in the aged, academic psychologists with a limited knowledge of the memory literature, and nonpsychologist college professors. There was little evidence that memory psychologists reported using strategies to remember things that were different from the strategies of other academics. The most used and most recommended technique for remembering was to write things down, followed by general internal mnemonic systems such as organization and rehearsal. The least used and least recommended strategies for all three groups were formal mnemonic systems, such as the peg-word system or the method of loci. 相似文献

Seclusion incidents were studied irr an undercrowded maximum security hospital where seclusion is used in response to episodes of violent or disruptive behavior. Population-based seclusion rates for days with an above-mean census were compared with those for days with a below-mean census. Contrary to expectations derived from studies of overcrowded prisons, the total seclusion rate was higher under low census conditions. Although the seclusion rate for parasuicide incidents was higher under high census conditions, seclusion rates for battery, assault, and disorderly conduct incidents were each higher under low census conditions. These findings are interpreted as indicating that correctional officers observe a smaller proportion of battery, assault, and disorderly conduct incidents under high census conditions. Such underdetection must be taken into account, along with underreporting, in studies of intrainstitutional incidents. 相似文献

The current experiment studies evidence for automatic processing of color and spatial dimensions present in matched pictures and words. Subjects studied four lists of either line drawings or matched words that varied in color (red or green) and position (left or right side), under one of four encoding conditions. Subjects were instructed to encode (1) only the item, (2) the item and its color, 13) the item and its position, or (4) the item and both color and position. All subjects participated in an unexpected final recognition task in which item recognition and recall for both attributes, regardless of original encoding instructions, we:re examined. Color memory appeared to be effortful for both pictures and words, as it was at chance level unless subjects were specifically instructed to encode the information. Position was most poorly recalled when subjects attended only to item information, but memory for this dimension was well above chance in all encoding conditions. The position of the line drawings was better recalled than the position of the words. The implications of these results for Hasher and Zacks’ (1979) model of automatic processes is discussed. 相似文献
