The influence of facial expressions of emotion on perceptions of affective sentence meaning was investigated by pairing happy, angry, suprised, and sad faces of “teachers” with sentences of varying affective tone. Ninety-five students judged the overall meaning communicated by these paired stimuli. The design allowed exploration of unique facial-verbal combination effects, overall cue integration effects, and sex differences. Clear effects of cue combinations emerged. Perceived sincerity was found to be a function of the consistency of evaluative (positivity) but not dominance cues. Perceived positivity was an interactive function of both evaluative cues and dominance cues. Perceived dominance was affected by the interaction of evaluative cues. The subtleties of cue combination were clarified through open-ended dependent measures. Also, as expected, females were found to be more sensitive than males to verbal-nonverbal cue conflict in perceptions of sincerity. However, no other sex differences were found. The findings were discussed with regard to the need for a firm empirical base upon which to integrate verbal and nonverbal research traditions in the communication of affective meaning. 相似文献

The study investigated how the sincerity of models affects their influence, using a delay-of-reward paradigm. Subjects were 40 fifth and sixth graders (ages 9 and 10 years, respectively), selected for delayed gratification patterns. In the experimental manipulation, sincerity or insincerity was explicitly attributed to the model or, in a neutral-model condition, no information about the model's sincerity was given. Subjects then observed the symbolically presented model's immediatereward choices, opposed to their own preferences. Immediately after treatment, children in all model conditions and in a fourth, no-model control group responded to a second delay-preference test. It was found that the influence of models varied substantially as a function of experimentally attributed sincerity. Insincere models had considerably less effect than sincere and neutral models, who provoked substantial and equivalent changes. Insincere models did not evoke significantly different change than occurred in the control group. A postexperimental inquiry showed the experimental manipulation had affected perceptions of the model's sincerity and liking for the model, with the insincere model rated considerably lower than the sincere and neutral models. The relevance of cognitive appraisal in observational learning was discussed. 相似文献

In a previous experiment, the authors demonstrated that kindergarten and first-grade children can be trained to test hypotheses sequentially within the context of a discrimination learning task. The present experiment is concerned with delineating various aspects of the pretraining that contribute to the improved hypothesis-testing strategies of kindergarten children (mean CA = 71.6 months). It was found that children who have learned to anticipate an invariant cue-reward relation in such tasks manifest improved hypothesis-testing behavior, as well as improved discrimination performance, whereas children who have been trained to identify and name the various stimulus components of the discriminanda do not perform better than those without such training. It was also found that children who have had practice in shifting from an irrelevant to a relevant dimension perform better than those who have not had such experience. Moreover, children who have been given explicit instruction and training in the use of win-stay and lose-shift rules, as well as in the use of valid hypotheses, manifest strategies superior to those without such training. Finally, extensive pretraining over two sessions, administered on separate days, resulted in a marked reduction in the proportion of children who were dimensionally fixated while solving discrimination problems with two genuine dimensions. 相似文献

Two experiments examined the development of conceptual preference for either thematic (functional) or taxonomic relationships in a match-to sample task. In Experiment 1 twenty subjects from each of five age groups—preschool to old age—completed a method of triads preference test where they were forced to choose a thematic or taxonomic match. Young and old individuals preferred the thematic parings while school age and college adults preferred the taxonomic matches. Although the Age × Preference relation was pronounced, the majority of subjects at all ages could provide adequate justification of both the preferred and nonpreferred relationship. In addition, kindergarten subjects in Experiment 2 could readily be trained to respond on the basis of the nonpreferred mode. These data suggest that the pervasive shift in conceptual responding from syntagmatic to paradigmatic, thematic to taxonomic, etc., represents a change in preference rather than a shift to a fundamentally new way of organizing knowledge. 相似文献

This paper attempted to examine how children, when confronted with a literary implicature, resolve this implicature under two types of social conditions. More specifically, this paper identified five types of strategies which people employ to resolve text anomalies arising when old information in a story setting is incompatible with new information in a story ending. Two experiments demonstrated that third graders (8.4 and 8.6 years) and sixth graders (12.5 and 12.8 years) consistently selected certain strategies for resolving old and new, empirical and value, contradictory information. Although third and sixth graders demonstrated a similar strategy preference for resolving contradictory old and new information in formal conditions, the principal difference was that third graders modified old information to fit new information while sixth graders modified new information to fit old information. In contrasting the formal and informal conditions, third graders shifted their strategy preferences so as to minimize the amount of text restructuring in the formal condition; sixth graders, on the other hand, shifted their strategy preferences so as to maximize the amount of text restructuring in informal conditions. These findings suggest that story schema structures are more interpretive than story grammar psychologists presently assume. 相似文献

Development of cerebral dominance: dichotic listening asymmetry in normal and learning-disabled children 总被引:1,自引:0,他引:1
The magnitude of the dichotic right-ear advantage was assessed in 48 normal and 48 learning-disabled children representing an age range of approximately 5 years. All subjects were matched according to age, sex, and handedness. An analysis of results indicated a significant right-ear advantage in both the normal and learning-disabled children, but revealed no developmental trends for either group. Differences observed in the performance of the learning-disabled and normal children may reflect variability in selective attention rather than differences in the degree of cerebral lateralization. These results suggest a need for a reconceptualization of the causative factors affecting children with learning disorders and lend support to the notion that cerebral lateralization is not a developmental phenomenon. 相似文献

Five event schedules (75:0, 75:25, 75:0:0, 72:25:0, 75:12.5:12.5) were examined in a size discrimination task with penny rewards and plastic token markers. The subjects were 100 fourth graders (mean age = 9.4 years) and 100 undergraduates of both sexes. Whether or not the event probabilities summed to unity proved to be a more important determiner of terminal performance than the number of response alternatives in the task (p < .01). Females maximized more than males (p < .001) and college students more than fourth graders (p < .001). Greater maximization was exhibited by fourth graders in the reward condition (p < .01). These reward effects appeared to be more consistent with a detrimental-effects-of-reward interpretation than either utility or expectancy interpretations. 相似文献

The use of the operant conditioning paradigm, as it has been applied to infant social, vocal behavior, reflects a failure to take into account the social nature of human infants over and above the rigid theoretical rationale of the paradigm. It is argued that: (1) the baseline procedure used in operant conditioning studies is methodologically and conceptually invalid; (2) the reinforcing stimulus used in social conditioning studies elicits the very response that it is assigned to reinforce; and (3) the effect of the response-reinforcer relationship is not the reinforcement (strengthening) of vocal response rate. 相似文献

Thirty-two infants aged 14 and 20 weeks were presented with a live face in each of eight conditions, which consisted of all combinations of (a) a 0° or 90° orientation; (b) familiar face (the infant's mother) or distinctively unfamiliar face; and (c) talking or silent context. The previous findings that younger infants smile longer at 0° than at 90° faces and that this differential responsiveness to orientation wanes with increasing age were replicated; the hypothesis that older infants would smile longest at their mothers' talking faces in the 0° orientation was confirmed. In addition, infants of both ages smiled more at their mothers than at the stranger, although this effect interacted with orientation and sex of the infant. 相似文献

Three studies were conducted to test whether imagery accounts for the effects of empathy on attributions, that is, whether attributers construct and scan a mental image of social scenarios the same way that actual participants scan a real environment. According to this interpretation, attributers “see” the world as the participant does and make vicarious attributions. An alternative interpretation holds that subjects base vicarious attributions on recreating the motivations and affect of the actor, so that imaging is irrelevant to empathy and attributions. In the first study, subjects who imagined a story from the perspective of a particular character later showed differential recall of story details as a function of role, but not differential attributions. In Experiment 2, role-taking subjects showed clear effects of imaged perspective on recall for story details, but no effects on attributions of causality for an accident. Further, recall and attribution were uncorrelated. In the last study, empathy and imagery role-taking instructions produced independent effects: imagers showed pronounced perspective-relevant recall and empathizers did not. Neither showed unambiguous vicarious attributions. Recall and attribution were again uncorrelated. These studies suggest that the imagery explanation of empathy effects is untenable, and imply that the recall of perspective-relevant details is unlikely to mediate attributions of causality in imaginary scenarios. 相似文献
