This paper presents an experiment that compared high and low working memory span readers' abilities to process Chinese subject-relative and object-relative clause structures in a self-paced reading paradigm. Comprehension performance results indicated that the object-relative structure was easier to understand than the subject-relative structure. Reading time results showed that participants with low working memory span read the subject-relative structures more slowly than the object-relative structures, but there was no reading time difference for the high working memory span participants. The experiment provides further evidence that the Chinese subject-relative clause structure is more difficult to process than the Chinese object-relative clause structure, especially for low working memory span individuals. Furthermore, these results support a syntactic storage account of the observed complexity difference. 相似文献

6~8岁儿童三种时间副词理解能力及策略的实验研究 总被引:1,自引:0,他引:1
采用定量与定性相结合的研究方法,对6~8岁儿童理解时间副词的能力进行了初步探查,结果表明:(1)不同年龄儿童对时间副词的理解能力不同。6岁和7岁儿童初步形成了对现在时间副词和过去时间副词的理解能力,萌发了对将来时间副词的理解能力;8岁儿童已具有了对现在时间副词和过去时间副词的理解能力,基本上具有了对将来时间副词的理解能力。(2)儿童在理解时间副词时多种策略并存。随着年龄的增长,有效策略的生成能力有了明显的提高,8岁儿童已有90%以上的人次能够使用有效策略。 相似文献

Variance estimates ofd′ are derived toward thesame-different method based on Taylor-series expansion with one and two variables. The variance estimates can be used for statistical comparison ofd′s obtained from various discrimination paradigms. Formulas and tables for estimating variance ofd′ for the method are provided. One S-PLUS program, which can produce bothd′ and variance ofd′, is also provided. 相似文献

A recent debate in the language production literature concerns the influence of a word’s orthographic information on spoken
word production and the extent to which this influence is modulated by task context. In the present study, Mandarin Chinese
participants produced sets of words that shared orthography (O+P−), phonology (O−P+), or orthography and phonology (O+P+),
or were unrelated (O−P−), in the context of a reading, associative naming, or picture naming task. Shared phonology yielded
facilitation effects in all three tasks, but only in the reading task was this phonological effect modulated by shared orthography.
Shared orthography by itself (O+P−) revealed inhibitory effects in reading, but not in associative naming or in picture naming.
These results suggest that a word’s orthography information influences spoken word production only in tasks that rely heavily
on orthographic information. 相似文献

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects. 相似文献

The Shedler-Westen assessment procedure (SWAP) is a personality assessment instrument designed for use by expert clinical assessors. Critics have raised questions about its psychometrics, most notably its validity across observers and situations, the impact of its fixed score distribution on research findings, and its test-retest reliability. We review empirical data addressing its validity, emphasizing the multitrait-multimethod approach to evaluating test validity. To evaluate the hypothesis that the fixed, asymmetric score distribution artifactually inflates correlations between SWAP profiles, we conducted Monte Carlo simulations and also presented empirical data from a large patient sample. We observed a mean correlation of zero between simulated SWAP profiles, indicating that the score distribution does not impact the correlation coefficients. Empirical correlations between SWAP profiles of actual patients were small and similar to those obtained using Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV) personality disorder scales that had no fixed score distributions, suggesting that the correlations were not a methodological artifact of the SWAP. We report new test-retest reliability data (median coefficient > .85) for the SWAP's trait and personality disorder dimensions. The SWAP appears to be reliable and valid. The data do not support its primary psychometric critiques. 相似文献

Describing co-occurring symptom patterns among children in nonwestern contexts may have important implications for how emotional
and behavior problems are defined, conceptualized, studied, and ultimately prevented. A latent profile analysis (LPA) was
conducted on the co-occurring psychiatric symptoms of 196 Chinese children living in poverty. Child depression, anxiety, aggression,
and self-esteem scores were used as indicators in the LPA. Three classes of symptoms best described the symptom presentations
of children in this study. Ninety-one percent of the youth in the sample were assigned to a class without clinically significant
elevations on any symptom index. Six percent fell into an externalizing class, and 3% were assigned to a class with elevated internalizing symptoms. The three
classes met empirical criteria for distinctiveness and were validated against parent- and child-rated family characteristics
and resources. Children in the externalizing class were more likely to experience harsh and neglectful parenting and their
parents were more likely to report avoidant coping styles. In addition to some parenting behaviors (overprotection and low
parental support), internalizing symptoms were uniquely associated with low levels of education, housing, economic, and social
resources. Implications for preventive interventions are discussed. 相似文献
