研究采用消失文本范式、操控双词消失的延迟时间,考察中文读者编码两个相邻词汇(词n与词n+1)视觉信息的年老化问题。结果发现,从40 ms延迟时间至160 ms延迟时间的所有消失条件均不影响青年人的句子总阅读时间,这意味着青年人能够并行、快速地同时编码词n与词n+1的视觉信息;而所有消失条件都影响老年人的句子阅读时间,40 ms延迟时间消失条件对总阅读时间的影响程度甚于其他较长延迟时间的消失文本条件,80 ms、120 ms和160 ms延迟时间消失条件对总阅读时间的影响程度完全相同。由这些结果可以确定,中文阅读中词汇视觉编码的年老化同时受视觉与认知因素衰退的影响。 相似文献

We used the Fuzzy-Trace Theory (FTT) perspective to investigate the role of context switching or reinstatement on correct and false recognition in Deese–Roediger–McDermott (DRM) and simple false memory for occurrence (FMO) tasks. In two experiments, participants studied words presented against unique picture backgrounds. The results indicated that providing specific item-context associative information in the reinstated-context test condition enhances verbatim trace retrieval of targets but does not influence their gist retrieval. In the case of false recognitions of related distracters, manipulations of retrieval context resulted in different effects across experiments, putatively because the DRM and FMO tasks involve different latent-processes implied by FTT. The results confirmed the critical role of retrieval conditions for false and correct recognition memory and showed the insights that can be gained from the process-level multinomial modelling analyses of data obtained in particular experimental paradigms. 相似文献

视觉隐喻是众多研究者比较关注的领域, 当前多以物体简笔画、漫画及广告等方面的研究为主, 但对与生活密切相关的实物的视觉隐喻研究甚少。因此研究采用掩蔽启动范式、李克特9点量表及语音生成等研究方法, 在物体概念类型(概念相同、概念相异)及形状类型(形状相似、形状相异)条件下, 针对实物图片的形状知觉相似性是否对视觉隐喻加工产生影响进行探讨。结果发现无论物体概念是否相同, 形状相似性对个体的物体识别具有“促进”作用, 并有利于视觉隐喻加工; 在物体识别中, 当两个物体概念不同时, 个体会试图建立一个特设类别来对形状相似的物体进行归类, 从而实现了视觉隐喻的加工。因此研究进一步证明了实物形状的知觉相似性有利于视觉隐喻的加工。 相似文献

Research on age-related cognitive change traditionally focuses on either development or aging, where development ends with adulthood and aging begins around 55 years. This approach ignores age-related changes during the 35 years in-between, implying that this period is uninformative. Here we investigated face recognition as an ability that may mature late relative to other abilities. Using data from over 60,000 participants, we traced the ability to learn new faces from pre-adolescence through middle age. In three separate experiments, we show that face learning ability improves until just after age 30 – even though other putatively related abilities (inverted face recognition and name recognition) stop showing age-related improvements years earlier. Our data provide the first behavioral evidence for late maturation of face processing and the dissociation of face recognition from other abilities over time demonstrates that studies on adult age development can provide insight into the organization and development of cognitive systems. 相似文献

The effects of selective adaptation on familiar face perception were examined. After prolonged exposure to photographs of a celebrity, participants saw a series of ambiguous morphs that were varying mixtures between the face of that person and a different celebrity. Participants judged fewer of the morphs to resemble the celebrity to which they had been adapted, implying that they were now less sensitive to that particular face. Similar results were obtained when the adapting faces were highly dissimilar in viewpoint to the test morphs; when they were presented upside-down; or when they were vertically stretched to three times their normal height. These effects rule out explanations of adaptation effects solely in terms of low-level image-based adaptation. Instead they are consistent with the idea that relatively viewpoint-independent, person-specific adaptation occurred, at the level of either the “Face Recognition Units” or “Person Identity Nodes” in Burton, Bruce and Johnston’s (1990) model of face recognition. 相似文献

Psychological studies of face recognition have typically ignored within-person variation in appearance, instead emphasising differences between individuals. Studies typically assume that a photograph adequately captures a person’s appearance, and for that reason most studies use just one, or a small number of photos per person. Here we show that photographs are not consistent indicators of facial appearance because they are blind to within-person variability. Crucially, this within-person variability is often very large compared to the differences between people. To investigate variability in photos of the same face, we collected images from the internet to sample a realistic range for each individual. In Experiments 1 and 2, unfamiliar viewers perceived images of the same person as being different individuals, while familiar viewers perfectly identified the same photos. In Experiment 3, multiple photographs of any individual formed a continuum of good to bad likeness, which was highly sensitive to familiarity. Finally, in Experiment 4, we found that within-person variability exceeded between-person variability in attractiveness. These observations are critical to our understanding of face processing, because they suggest that a key component of face processing has been ignored. As well as its theoretical significance, this scale of variability has important practical implications. For example, our findings suggest that face photographs are unsuitable as proof of identity. 相似文献

Previous literature in alphabetic languages suggests that the occipital-temporal region (the ventral pathway) is specialized for automatic parallel word recognition, whereas the parietal region (the dorsal pathway) is specialized for serial letter-by-letter reading (
[Cohen et al., 2008]
and
[Ho et al., 2002]
). However, few studies have directly examined the role of the ventral and dorsal pathways in Chinese reading compared to English reading. To investigate this issue, we adopted the degraded word processing paradigm used by Cohen et al. (2008) and compared brain regions involved in the processing of degraded Chinese characters and English words during lexical decision, using functional magnetic resonance imaging (fMRI). The degraded characters/words were created by inserting blank spaces between radicals of Chinese characters or syllables of English polysyllabic words. Generally, the current study replicated the effects of Cohen et al. (2008), showing that in Chinese – like in alphabetic languages – character spacing modulates both ventral (bilateral cuneus, left middle occipital gyrus) and dorsal (left superior parietal lobule and middle frontal gyrus) pathways. In addition, the current study showed greater activation in bilateral cuneus and right lingual gyrus for Chinese versus English when comparing spaced to normal stimuli, suggesting that Chinese character recognition relies more on ventral visual-spatial processing than English word recognition. Interestingly, bilateral cuneus showed monotonic patterns in response to increasing spacing, while the rest of the regions of interest showed non-monotonic patterns, indicating different profiles for these regions in visual-spatial processing. 相似文献

National income has a pervasive influence on the perception of ingroup stereotypes, with high status and wealthy targets perceived as more competent. In two studies we investigated the degree to which economic wealth of raters related to perceptions of outgroup competence. Raters’ economic wealth predicted trait ratings when (1) raters in 48 other cultures rated Americans’ competence and (2) Mexican Americans rated Anglo Americans’ competence. Rater wealth also predicted ratings of interpersonal warmth on the culture level. In conclusion, raters’ economic wealth, either nationally or individually, is significantly associated with perception of outgroup members, supporting the notion that ingroup conditions or stereotypes function as frames of reference in evaluating outgroup traits. 相似文献
