Semantic focus and sentence comprehension.   总被引:5,自引:0,他引:5  
A Cutler  J A Fodor 《Cognition》1979,7(1):49-59
Reaction time to detect a phoneme target in a sentence was found to be faster when the word in which the target occurred formed part of the semantic focus of the sentence. Focus was determined by asking a question before the sentence; that part of the sentence which comprised the answer to the sentence was assumed to be focussed. This procedure made it possible to vary position of focus within the sentence while holding all acoustic aspects of the sentence itself constant. It is argued that sentence understanding is facilitated by rapid identification of focussed information. Since focussed words are usually accented, it is further argued that the active search for accented words demonstrated in previous research should be interpreted as a search for semantic focus.  相似文献

The present study explores two questions: What is the nature of older children's syntactic knowledge; how is that knowledge used in an everyday speech situation? Six-, eight-, and ten-year-olds repeated grammatical sentences as read by the first experimenter. Half the sentences were syntactically clear, half slightly distorted. Clear versions displayed basic grammatical relations and constituent structure perspicuously. The second experimenter, who sat at the other end of the room, asked “What?” after each sentence. The syntactic changes children might make to accommodate the listener were examined. Although the children made a variety of changes, at all ages they tended to change distorted versions to clear ones, and to repeat clear versions. The results suggest that children's syntactic knowledge is deeper and more accessible than had been supposed.  相似文献

This investigation attempted to assess the effectiveness of two components of parent training programs: (1) the effect of a self-behavior management project prior to intervention with deviant child behaviors, and (2) that of social reinforcement from peers and the consultant. Four groups of parents were exposed to a basic training program and were measured on their success in an intervention program in the inappropriate behavior of their children (ages 7–9 years). Two groups of parents were requested to do a self-modification program prior to the intervention with deviant child behavior; two groups did a child intervention program without a self-management project. One group in the self-management and one group without self-management received verbal social reinforcement from peers and the consultant during interventions. Results obtained indicate that the parent group whose training involved a self-behavior management project prior to intervention with their child's inappropriate behavior and verbal social reinforcement achieved a significantly greater reduction of these behaviors when compared to the groups where either self-management of social reinforcement was used.  相似文献

The present study focused on the executive monitoring of a rehearsal strategy by sixth (11 years 5 months), tenth (15 years 8 months), and twelfth (17 years 9 months) graders and adults (27 years 4 months). The results showed that all of the adults spontaneously adopted an “optimal” strategy and generalized it to a second task. However, none of the sixth graders and only two tenth and three twelfth graders did so. All of the school subjects subsequently trained to rehearse, maintained the strategy without prompting, and showed evidence of transfer. In comparison to adults, the trained subjects' generalized routines became more similar to the adults' as grade increased. This study supports the notion that efficient executive functioning includes the case where continued use of a mnemonic routine is a reasonable response to an objective change in an information-processing task.  相似文献

Previous studies of children's performance on quantitative identity and equivalence conservation problems in the number domain are suggested to be flawed because of the low numbers of items in the arrays. In Experiment 1, children were tested on three different number versions of identity and equivalence conservation tasks. Their performance varied with the number of items and no child was found to pass a large number version of an equivalence conservation task and fail the corresponding version of an identity conservation task. In Experiment 2 the notion that the contextual effect of asking two similar questions might underlie the difference in performance on the two tasks was tested and rejected. The results are discussed in relation to recent analyses of conservation problems.  相似文献
