To address the fundamental question of “what are the primitives of visual perception”, a theory of topological structure and functional hierarchy in visual perception has been proposed. This holds that the global nature of perceptual organization can be described in terms of topological invariants, global topological perception is prior to the perception of other featural properties, and the primitives of visual form perception are geometric invariants at different levels of structural stability. In Part I of this paper, I will illustrate why and how the topological approach to perceptual organization has been advanced. In Part II, I will provide empirical evidence supporting the early topological perception, while answering some commonly considered counteraccounts. In Part III, to complete the theory, I will apply the mathematics of tolerance spaces to describe global properties in discrete sets. In Part IV, I will further present experimental data to demonstrate the global-to-local functional hierarchy in form perception, which is stratified with respect to structural stability defined by Klein's Erlangen Program. Finally, in Part V, I will discuss relations of the global-to-local topological model to other theories: The topological approach reformulates both classical Gestalt holism and Gibson's direct perception of invariance, while providing a challenge to computational approaches to vision based on the local-to-global assumption. 相似文献

Cortical function and related cognitive, language, and communication skills are genetically influenced. The auditory brainstem response to speech is linked to language skill, reading ability, cognitive skills, and speech‐in‐noise perception; however, the impact of shared genetic and environmental factors on the response has not been investigated. We assessed auditory brainstem responses to speech presented in quiet and background noise from (1) 23 pairs of same sex, same learning diagnosis siblings (Siblings), (2) 23 unrelated children matched on age, sex, IQ, and reading ability to one of the siblings (Reading‐Matched), and (3) 22 pairs of unrelated children matched on age and sex but not on reading ability to the same sibling (Age/Sex‐Matched). By quantifying response similarity as the intersubject response‐to‐response correlation for sibling pairs, reading‐matched pairs, and age‐ and sex‐matched pairs, we found that siblings had more similar responses than age‐ and sex‐matched pairs and reading‐matched pairs. Similarity of responses between siblings was as high as the similarity of responses collected from an individual over the course of the recording session. Responses from unrelated children matched on reading were more similar than responses from unrelated children matched only on age and sex, supporting previous data linking variations in auditory brainstem activity with variations in reading ability. These results suggest that auditory brainstem function can be influenced by siblingship and auditory‐based communication skills such as reading, motivating the use of speech‐evoked auditory brainstem responses for assessing risk of reading and communication impairments in family members. 相似文献

Previous studies have shown that Asian American or Chinese individuals value low-arousal positive affect and a harmonious state of happiness more than European Americans do. However, the affective component of subjective well-being has mostly been defined as the presence of positive affect and the absence of negative affect. This definition emphasizes the importance of hedonic pleasure but fails to include the affect valued in Chinese culture. The present study developed the construct of peace of mind to describe the affective well-being valued in Chinese culture. Peace of mind was defined as an internal state of peacefulness and harmony. To develop a measure to assess peace of mind, three studies were conducted. Study 1 developed the Peace of Mind Scale (PoM), Study 2 established its validity as an affective well-being measure, and Study 3 found that individuals from Chinese cultures score higher on this scale than those from Western cultures. The results indicate that the PoM has good reliability and validity for measuring affective well-being. The cross-cultural validation also found that Taiwanese individuals scored higher on the PoM than European Americans, which provides further evidence of good construct validity of the PoM. 相似文献

Both emotional words and words focused by information structure can capture attention. This study examined the interplay between emotional salience and information structure in modulating attentional resources in the service of integrating emotional words into sentence context. Event-related potentials (ERPs) to affectively negative, neutral, and positive words, which were either focused or nonfocused in question–answer pairs, were evaluated during sentence comprehension. The results revealed an early negative effect (90–200 ms), a P2 effect, as well as an effect in the N400 time window, for both emotional salience and information structure. Moreover, an interaction between emotional salience and information structure occurred within the N400 time window over right posterior electrodes, showing that information structure influences the semantic integration only for neutral words, but not for emotional words. This might reflect the fact that the linguistic salience of emotional words can override the effect of information structure on the integration of words into context. The interaction provides evidence for attention–emotion interactions at a later stage of processing. In addition, the absence of interaction in the early time window suggests that the processing of emotional information is highly automatic and independent of context. The results suggest independent attention capture systems of emotional salience and information structure at the early stage but an interaction between them at a later stage, during the semantic integration of words. 相似文献

Previous research has shown that people use warmth and competence as basic dimensions to evaluate others and to interpret their behavior, but little research has examined the conditions under which low-warmth targets are liked. A series of 3 experiments involving 4 vignettes showed, in general, that low-warmth targets were better liked when they exhibited higher competence and that high-status persons displayed greater tolerance toward the low-warmth person of low status. Exceptions to these patterns were predicted and found as a function of the type of organizational context in which evaluations were made: groups that place priority on individual goals over common goals and groups that are performance oriented rather than relationship oriented. Target gender interacted with competence and relative status. 相似文献

Goodness-of-fit testing in factor analysis is based on the assumption that the test statistic is asymptotically chi-square, but this property may not hold in small samples even when the factors and errors are normally distributed in the population. Robust methods such as Browne's (1984) asymptotically distribution-free method and Satorra Bentler's (1988, 1994) mean scaling statistic were developed under the presumption of nonnormality in the factors and errors. This article finds new application to the case where factors and errors are normally distributed in the population but the skewness of the obtained test statistic is still high due to sampling error in the observed indicators. An extension of Satorra Bentler's statistic is proposed that not only scales the mean but also adjusts the degrees of freedom based on the skewness of the obtained test statistic in order to improve its robustness under small samples. A simple simulation study shows that this third moment adjusted statistic asymptotically performs on par with previously proposed methods and at a very small sample size offers superior Type I error rates under a properly specified model. Data from Mardia, Kent, and Bibby's (1980) study of students tested for their ability in 5 content areas that were either open or closed book were used to illustrate the real-world performance of this statistic. 相似文献

We describe a set of pictorial and auditory stimuli that we have developed for use in word learning tasks in which the participant learns pairings of novel auditory sound patterns (names) with pictorial depictions of novel objects (referents). The pictorial referents are drawings of "space aliens," consisting of images that are variants of 144 different aliens. The auditory names are possible nonwords of English; the stimulus set consists of over 2,500 nonword stimuli recorded in a single voice, with controlled onsets, varying from one to seven syllables in length. The pictorial and nonword stimuli can also serve as independent stimulus sets for purposes other than word learning. The full set of these stimuli may be downloaded from www.psychonomic.org/archive/. 相似文献
