Semantic priming was analysed in two groups of French children contrasted on comprehension skills with a visual lexical-decision task using a long SOA (800 ms). Two relation types between related primes and targets were examined: pure semantic relation (categorical vs. functional), and lexical association strength (strong vs. weak). Targets were preceded by related, unrelated, and neutral primes. Skilled comprehenders showed semantic priming only for category-related words, whatever their association strength, and without any evidence of an associative boost. Less-skilled comprehenders also showed semantic priming for category-related words, irrespective of their association strength, but with an indication of an associative boost. They also displayed semantic priming for function-related awords that are strongly associated, but not for those that are weakly associated. These results are discussed within the theoretical frame proposed by Plaut and Booth (2000). 相似文献

Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the impact of self-focus on the performance of normal individuals. The present study examines the role of task difficulty, task self-relevance, and presence of evaluation anxiety in the performance effects of self-focus among normal individuals. Participants performed a simple reaction time (RT) and a lexical decision task, in Experiments 1 and 2, respectively, with or without self-focus. Self-focus and evaluation anxiety resulted in faster responding in simple RT, but there was no significant effect of self-focus on performance in the more difficult lexical decision task. Participants' heart rate (HR) was monitored and indicated that orienting was associated with slower RT in both experiments, and less orienting was found during self-focus and evaluation conditions. Results are interpreted in light of several self-focus theories. 相似文献
