Twenty normal, twenty left-, and fifteen right-brain injured subjects, all right-handed, were assigned a sequence of voluntary inhibition of 23 movements. The inhibition lapse was recorded. Statistical analyses indicated a high performance in the normal and a deficient performance in left-brain injured subjects, no influence of the neurological symptoms on groups' achievement, a handicap in the subjects affected by a frontal lesion in the right brain, a hierarchical clustering of items varying according to the groups, and an organ-group interaction. 相似文献

Previous researchers have manipulated forewarning by providing premessage information about the topic and position of the upcoming communication, or the communicator's persuasive intent. Subjects in the present experiment were force-warned either 10 min prior to the communication, or just before the message began of the speaker's topic and position, persuasive intent, or topic only. As hypothesized, forewarning of the communicator's persuasive intent inhibited persuasion regardless of the length of the delay period, but forewarning of the topic and position required a delay in order to confer resistance to subsequent persuasion, suggesting that although both manipulations have been called “forewarning they may lead to reduced persuasion through different mechanisms. Foreknowledge of the source's topic, but not his position also increased resistance to persuasion when followed by a delay period. The results were discussed in terms of both cognitive and motivational mechanisms that may underly the persuasion inhibiting effects of forewarning. 相似文献

Children aged 6, 8, and 10 years were exposed to three types of training procedures aimed at increasing their use of constraint-seeking questions and enhancing their problem-solving efficiency. One group observed an exemplary model who merely illustrated several constraint-seeking questions. Another group observed a cognitive model who, prior to asking each of her constraint-seeking questions, verbalized her strategy for formulating constraint-seeking questions and integrating the information gained from such questions. A third group received a combination of cognitive modeling and self-rehearsal training in which the children repeated statements representing key features of the constraint-seeking strategy before asking questions on a series of training items. Cognitive modeling alone was the most successful training procedure, effecting changes in both constraint-seeking questioning and problem-solving efficiency for children of all three age groups. Differences between cognitive and exemplary models were most notable among the youngest children, who appeared to require the additional guidance afforded through the verbalizations of the cognitive model. 相似文献

A 2-year follow-up study of public vocational school graduates revealed that the graduates successfully obtained jobs. Among the factors deemed important by both graduates and employer, communication skills were mentioned as vital. Counseling and preparation in getting along with others were perceived by graduates as inferior. Except for cooperative work program graduates, adjustment to an 8 hr workday caused some problems. 相似文献

Task differences were assessed with 120 first graders in a 2 × 3 × 3 factorial design combining Socioeconomic level (middle vs lower), Concepts (conservation of length, transitivity of length, and conservation of continuous quantity), and Tasks (three tasks for each concept selected on the basis of frequency of usage). As predicted, task by concept interactions were found on all four task response measures. This finding is consistent with Piaget's concept of horizontal decalage and with Flavell and Wohlwill's competence-performance model, which proposes that intermediate phases of stage transition are characterized by considerable intertask differences and initial and final phases by intertask consistency in performance. The importance of investigating the effects of task variables on multiple dependent measures at various age levels and points in time was emphasized. Concept, task, and socioeconomic class differences were also found on some of the measures. 相似文献

A polar-coordinate analogue of Fourier synthesis generates organic-appearing “free forms” that can be continuously deformed along any desired number of difficult-to-verbalize dimensions. Since the dimensions are also circular, the forms correspond to points on the surface of a torus which, though conveniently finite, is free of bounding edges. Two experiments explore a particular two-dimensional set of 81 such forms. The first shows that perceived pair-wise similarities among the individual forms are well explained purely in terms of the distances among their corresponding points in the toroidal parameter space. The second, however, establishes that forms that tend to be grouped together as having the same cognitive interpretation define regions in parameter space that are variously shaped or even bimodal and, hence, that cannot be explained solely on the basis of the fixed set of pair-wise similarities. The stimuli appear to offer a novel combination of cognitive richness and low-dimensional parametric control. 相似文献
