This study concerned the prediction of children's learning with an individual measure of intelligence and teachers' evaluations. Eight abstract and eight concrete nouns were paired with nonsense geometric figures and presented to 60 elementary school children in a three-trial paired-associate (PA) learning task. Subjects' IQ scores on the Wechsler Intelligence Scale for Children-Revised and teachers' ratings of learning proficiency were used to predict children's performance on the PA task. Multiple correlations favored abstract learning with verbal scale intelligence, accounting for the majority of the variability. Teachers' ratings provided a surprising degree of predictive efficiency for abstract recall which was redundant with verbal intelligence. 相似文献

Seventy-one normotensive subjects participated in four training sessions in which they were either (a) instructed to increase their blood pressure, (b) instructed to decrease their blood pressure, or (c) not instructed to change their blood pressure. The subjects either (a) were provided with biofeedback concerning systolic blood pressure or (b) were not provided with biofeedback concerning systolic blood pressure. After the last training session, subjects participated in a transfer session in which they were again instructed concerning changes in pressure but were not provided with biofeedback. Analyses conducted on data from the training and transfer sessions indicated that subjects who were instructed to increase pressure and given biofeedback to aid them showed higher pressure than subjects in other conditions and that there were no differences among those other conditions; that is, biofeedback was effective for teaching subjects to increase pressure but was not effective for teaching subjects to decrease pressure. Additional training sessions did not add to the effect achieved in the first training session. During training sessions, subjects who were instructed to increase pressure showed higher heart rates than subjects in other conditions. The results raise questions concerning the interpretation of earlier experiments that did not include no-treatment, instructions-only, and attention control conditions. 相似文献

Recent research reviewed in this article suggests that stutterers' inability to initiate phonation promptly could be a significant factor in the occurence of stuttering. Since stuttering is either completely absent or markedly reduced in frequency during whisper, the present study tested the hypothesis that stutterers do not significantly differ from nonstutterers in reaction time (RT) for the initiation of whispered/a/, whereas the two groups differ significantly in RT for the initiation of voiced /a/. Ten adult stutterers and an equal number of comparable nonstutterers produced prolonged versions of the vowel /a/ using voice and whisper in response to tone stimuli. The results showed that stutteres and nonstutterers did not differ in RT for either voiced or whispered /a/. The stutterers, however, exhibited significantly longer RT to produce voiced /a/ than whispered /a/. 相似文献

A mathematical model based upon signal detection theory is developed that characterizes social influences upon judgments of a stimulus. A social influence cue and the physical aspects of the stimulus were assumed to have independent effects upon performance. A visual movement discrimination task was employed in which subjects could make their judgment either before or after a cue that they had been led to believe was the response of another subject. The accuracy of this “response” was varied. The model provided a good account of the data. A model-based estimate of the magnitude of the influence effect indicated that this effect was greater when the “other” was highly accurate. The model provided an interpretation of social influences on perceptual judgments in which influence pressures have their effects only when subjects' sensory impressions are ambiguous. 相似文献

The goal of this article was to investigate the mechanisms through which personality relates to task performance. We argue that perceptions of work pressure and task complexity trigger momentary levels of neuroticism (i.e., state neuroticism) and that these momentary levels of neuroticism predict momentary task performance. Moreover, we hypothesized that the relationship between momentary job demands and state neuroticism is moderated by trait neuroticism. To test this model, we conducted an event reconstruction study and a day reconstruction study. The results revealed that trait neuroticism indeed moderated the momentary job demands–state neuroticism relationship, and in three out of four cases state neuroticism was found to mediate the relationship between momentary job demands and momentary task performance. From a practical point-of-view our results suggest that employees’ task performance can be improved by enhancing the way in which individuals perceive job demands. This strategy would be particularly helpful for individuals for whom the momentary job demands–state neuroticism relationship is the strongest (i.e., employees high in trait neuroticism). 相似文献
