可成字部件在汉字中的位置和功能多种多样。实验1采用部件启动范式考察在汉字识别中可成字部件在不同位置的功能。启动刺激为处于三种位置(主要义符位置、次要义符位置、声符位置)的可成字部件, 目标刺激为包含这三种位置可成字部件的汉字, 要求被试对目标字做词汇判断。实验2结合部件启动范式和视觉搜寻范式探查可成字部件在不同位置的功能。结果表明:(1)可成字部件处在声符位置时的启动效应强于处在义符位置时。(2)可成字部件作义符时的启动作用只出现在处于主要义符位置时。(3)处在声符位置的可成字部件启动不仅促进对包含声符位置部件的汉字的识别, 还促进对包含主要义符位置部件的汉字的识别, 但阻碍对包含次要义符位置部件的汉字的识别。(4)当启动部件处于次要义符位置时, 不影响对包含相关部件的汉字的识别。整个研究表明, 部件位置效应不仅包含部件位置对汉字识别的影响, 还包含部件位置频率对汉字识别的影响。 相似文献

This study examines women's media selections when under the gender–math stereotype threat and the subsequent media effects on their math performance through the lens of the Selective Exposure Self‐ and Affect‐Management (SESAM) model, mood management theory, and social comparison theory. Female college students were randomly assigned to the stereotype threat condition or the control condition; then, they selectively browsed magazine pages showing female role models in stereotypical domains (beauty or family) and counterstereotypical domains (career or science) before taking the math test. The results show that women spent more time on career magazines when under threat, and this selective exposure's effect on their math performance was moderated by their assimilation to the role models. 相似文献

Studies found that subliminal primes can be associated with specific tasks to facilitate task performance, and such learning is highly adaptive and generalizable. Meanwhile, conditioning studies suggest that aversive/reward learning and generalization actually occur at the semantic level. The current study shows that prime–task associations can also be generalized to novel word/neighbour primes from the same semantic category, and this occurs without contingency awareness. Previous studies have counterintuitively suggested that both the learning of task priming and the semantic priming of word neighbours depend on the lack of visibility. Here, we show that semantic generalization indeed depends on reduced visibility, but cannot occur subliminally. The current study shows for the first time that semantic learning and generalization can occur without any emotional or motivational factors, and that semantic priming can occur for arbitrary-linked stimuli in a context completely devoid of semantics. 相似文献

Weak correspondence across different implicit bias tasks may arise from the contribution of unique forms of automatic and controlled processes to response behavior. Here, we examined the correspondence between estimates of automatic and controlled processing derived from two sequential priming tasks with identical structure and timing designed to separately measure stereotypic (Weapons Identification Task; WIT) and evaluative (Affective Priming Task; APT) associations. Across two studies using predominantly White samples, three consistent patterns emerged in the data: (a) stereotypic bias was stronger for Black targets, whereas evaluative bias was stronger for White targets; (b) overall response accuracy bias correlated modestly across the two tasks; and (c) multinomial processing tree estimates of controlled processing corresponded much more strongly than estimates of automatic processing. These findings support models positing distinct learning and memory systems for different forms of race bias, and suggest that these differing forms contribute to estimates of automatic associations. 相似文献

Word fragment completion performance was examined for items that were presented in the same or different letter case at study and test. During the study phase words and nonwords were presented at central fixation, then during the test phase a divided visual field technique was used in which word fragments were presented briefly to the right hemisphere (left visual field) or the left hemisphere (right visual field). Previous research using the word stem completion task indicated that only the right hemisphere was sensitive to case changes in words from study to test. In contrast, the current results indicate that in the fragment completion task the priming effects for the test items presented to either hemisphere were greater when the fragments were in the same compared to different letter case at study and test. These results indicate that both hemispheres are capable of supporting form-specific visual implicit memory. 相似文献

Even once children can accurately remember their experiences, they nevertheless struggle to use those memories in flexible new ways—as in when drawing inferences. However, it remains an open question as to whether the developmental differences observed during both memory formation and inference itself represent a fundamental limitation on children's learning mechanisms, or rather their deployment of suboptimal strategy. Here, 7–9-year-old children (N = 154) and young adults (N = 130) first formed strong memories for initial (AB) associations and then engaged in one of three learning strategies as they viewed overlapping (BC) pairs. We found that being told to integrate—combine ABC during learning—both significantly improved children's ability to explicitly relate the indirectly associated A and C items during inference and protected the underlying pair memories from forgetting. However, this finding contrasted with implicit evidence for memory-to-memory connections: Adults and children both formed A-C links prior to any knowledge of an inference test—yet for children, such links were most apparent when they were told to simply encode BC, not integrate. Moreover, the accessibility of such implicit links differed between children and adults, with adults using them to make explicit inferences but children only doing so for well-established direct AB pairs. These results suggest that while a lack of integration strategy may explain a large share of the developmental differences in explicit inference, children and adults nevertheless differ in both the circumstances under which they connect interrelated memories and their ability to later leverage those links to inform flexible behaviours.
Research Highlights
- Children and adults view AB and BC pairs related through a shared item, B. This provides an opportunity for learners to connect A–C in memory.
- Being encouraged to integrate ABC during learning boosted performance on an explicit test of A–C connections (children and adults) and protected from forgetting (children).
- Children and adults differed in when implicit A–C connections were formed—occurring primarily when told to separately encode BC (children) versus integrate (adults), respectively.
- Adults used implicit A–C connections to facilitate explicit judgments, while children did not. Our results suggest developmental differences in the learning conditions promoting memory-to-memory connections.

We present interpretation-based processing—a theory of sentence processing that builds a syntactic and a semantic representation for a sentence and assigns an interpretation to the sentence as soon as possible. That interpretation can further participate in comprehension and in lexical processing and is vital for relating the sentence to the prior discourse. Our theory offers a unified account of the processing of literal sentences, metaphoric sentences, and sentences containing semantic illusions. It also explains how text can prime lexical access. We show that word literality is a matter of degree and that the speed and quality of comprehension depend both on how similar words are to their antecedents in the preceding text and how salient the sentence is with respect to the preceding text. Interpretation-based processing also reconciles superficially contradictory findings about the difference in processing times for metaphors and literals. The theory has been implemented in ACT-R [Anderson and Lebiere, The Atomic Components of Thought, Lawrence Erlbaum Associates Publishers, Mahwah, NJ, 1998]. 相似文献

Conscious and unconscious emotions are related to mental rotation. In this study, we investigated if also unconscious emotional evaluations of the stimuli are related to mental rotation performance. 114 students (39 men, 75 women) solved implicit and explicit affective evaluations and a psychometric mental rotation test with cube and pellet figures. Furthermore, the use of spatial toys, the stereotyping of spatial abilities, and the self-rating in spatial abilities were registered. The mental rotation test with pellet figures was more difficult than the one with cube figures. Mental rotation performance was predicted by the self-rating of spatial abilities. For the cube figures, it was additionally predicted by the implicit affective evaluation of those figures. The results did not differ between men and women. The study provides evidence for a relation between affective emotional evaluations and mental imagery processes, although this does not hold true for all stimulus types. 相似文献

Holistic processing (HP) of faces is usually measured by the composite effect. While Weston and Perfect [2005. Effects of processing bias on the recognition of composite face halves. Psychonomic Bulletin & Review, 12, 1038–1042. doi:10.3758/BF03206440] found that priming at the local level speeded recognition of components of faces, Gao et al. [2011. Priming global and local processing of composite faces: Revisiting the processing-bias effect on face perception. Attention Perception & Psychophysics, 73, 1477–1486. doi:10.3758/s13414-011-0109-7] found that only global priming had an effect on HP of faces. The two studies used different versions of the composite task (the partial design, which is considered to be prone on bias, and the complete design). However, the two studies also differed in other respects and it is difficult to know to what extent issues with the partial design contributed to the differing conclusions. In the present study, the HP indexed by the complete design measure was augmented by global priming. In contrast, no effect was observed in the partial design index. We claim that the partial design index reflects other factors besides HP, including response bias, and conclude that HP can be understood within the context of domain-general attentional processes. 相似文献
