This study investigated age of acquisition (AoA) effects on processing grammatical category information of Chinese single-character words. In Experiment 1, nouns and verbs that were acquired at different ages were used as materials in a grammatical category decision task. Results showed that the grammatical category information of earlier acquired nouns and verbs was easier to retrieve. In Experiment 2, AoA and predictability from orthography to grammatical category were manipulated in a grammatical category decision task. Results showed larger AoA effects under lower predictability conditions. In Experiment 3, a semantic category decision task was used with the same materials as those in Experiment 2. Different results were found from Experiment 2, suggesting that the grammatical category decision task is not merely the same as the semantic category decision task, but rather involves additional processing of grammatical category information. Therefore the conclusions of Experiments 1 and 2 were strengthened. In summary, it was found for the first time that AoA affects the retrieval of grammatical category information, thus providing new evidence in support of the arbitrary mapping hypothesis. 相似文献

In two experiments, participants' eye movements were monitored as they read sentences containing biased syntactic category ambiguous words with either distinct (e.g., duck) or related (e.g., burn) meanings or unambiguous control words. In Experiment 1, prior context was consistent with either the dominant or subordinate interpretation of the ambiguous word. The subordinate bias effect was absent for the ambiguous words in gaze duration measures. However, effects of ambiguity did emerge in other measures for the ambiguous words preceded by context supporting the subordinate interpretation. In Experiment 2, context preceding the target words was neutral. Ambiguity effects only arose when posttarget context was consistent with the subordinate interpretation of the ambiguous words, indicating that readers initially selected the dominant interpretation. Results support immediate theories of syntactic category ambiguity resolution, but also suggest that recovery from misanalysis of syntactic category ambiguity is more difficult than for lexical-semantic ambiguity in which alternate interpretations do not cross syntactic category. 相似文献

关系类别是指类别的成员身份由一个共同的关系结构决定。其意义来自于其与其他实体的关系或其内部的一系列成分间的关系,关系类别强调关系结构的系统性。文章重点介绍和评述了相似性种类,关系类别和实体类别的联系和差异,关系类别的学习过程及机制———结构—映射理论。未来的研究方向主要是探索新的研究范式,以深入理解关系类别的学习;深入探讨校准和映射过程与其他基本认知过程的相互作用,为关系类别的学习提供更一致的认知观点。 相似文献

A hybrid product (i.e. a multifinal means) is connected with goals relevant to the key functionalities best served by the product categories constituting the product. Given that single‐ or multiple‐category inference for a hybrid product can be elicited in individuals, we propose that single‐ (vs. multiple‐) category inference can lead to a relatively higher preference for the hybrid product if only one of the key focal goals that the hybrid product can satisfy is activated. We also explore whether the evaluation of a hybrid product in single‐category inference will reflect valuation and/or devaluation effects if only one of multiple key focal goals attached to the hybrid product is active. 相似文献

范畴变量对虚假记忆的影响 总被引:2,自引:2,他引:0
以中文词为材料,考察范畴样例重复,样例熟悉性、典型性和范畴大小对虚假再认的影响。实验1表明,随着范畴样例增加,虚假再认也增加。实验2表明,对高熟悉的样例虚假再认多。实验3表明,对高典型样例更易虚假再认。实验4表明,和大范畴样例比,对小范畴样例有更多的虚假再认。整个结果可以用激活扩散理论统一地加以解释 相似文献

We propose category theory, the mathematical theory of structure, as a vehicle for defining ontologies in an unambiguous language
with analytical and constructive features. Specifically, we apply categorical logic and model theory, based upon viewing an
ontology as a sub-category of a category of theories expressed in a formal logic. In addition to providing mathematical rigor,
this approach has several advantages. It allows the incremental analysis of ontologies by basing them in an interconnected
hierarchy of theories, with an operation on the hierarchy that expresses the formation of complex theories from simple theories
that express first principles. Another operation forms abstractions expressing the shared concepts in an array of theories.
The use of categorical model theory makes possible the incremental analysis of possible worlds, or instances, for the theories,
and the mapping of instances of a theory to instances of its more abstract parts. We describe the theoretical approach by
applying it to the semantics of neural networks. 相似文献

The Asian American population comprises historically, socially, and culturally diverse ethnic groups. Given this diversity,
investigators caution that combining disparate ethnic groups together may lead to erroneous conclusions. Whether by choice
or necessity, however, mental health studies still typically consider Asian Americans as a single ethnic category rather than
as separate ethnic groups. Few investigations have addressed the consequences of this practice. This paper examines the implications
of conceptualizing Asian Americans as an ethnic category versus ethnic groups, in an investigation of the community functioning
status of clients in publicly funded mental health programs in King County, Washington. When treated as a single ethnic category
in a multivariate linear regression model, Asian Americans are found to have a lower level of functioning difficulty than
their white counterparts. However, when treated as separate ethnic groups (e.g., Vietnamese, Japanese), only one of five Asian
ethnic groups has a significantly lower level of difficulty. In a separate analysis of the Asian American subsample, groups
are found to differ significantly from one another with respect to functional status. Several factors, including refugee status,
account for this difference. 相似文献

This study investigated how consistency between categories and attributes determines attribute selection in hierarchical category learning. Participants learned six categories for which number and color were equally relevant attributes, followed by a transfer task, to test which attribute was used. Before that, half of them learned embedding higher-level categories for which numbers were likely to be used. Orthogonal to this factor, the hierarchical structure was made explicit for half of them by category labels. The results showed that participants used numbers in the prior learning, but that the use of numbers was inhibited in the subsequent six-category learning task. However, this inhibitory effect was reduced when the hierarchical structure was explicit. The pattern of results suggests that attribute selection is determined by structural consistency between categories and attributes, not by a prior use of an attribute. 相似文献
