This study was addressed to the determination of the stage at which semantic analysis occurs during a STM recognition task. A list of exemplars (memory set), drawn from 13 different categories, was presented at a rate of 11/2 sec/item, followed by a category name probe. Ss then indicated whether any of the exemplars in the memory set belonged to that category. List length was varied from 5 to 7, with each memory set containing items from either two or three categories. It was found that RT was independent of list length, but did increase by 60 msec as the number of categories represented in the list increased from two to three. From this, it was concluded that activation of a superordinate category representation occurred upon presentation of each memory-set item, and that the memory scan was done on these superordinate categories. 相似文献

Horner's (1968) “fear of success” study was replicated and expanded. One hundred seventy-seven high school (HS) and college students wrote stories in response to the following cues: “After first-term finals, John (Anne) finds himself (herself) at the top of his (her) medical-school class.” Results indicated similarity of response of HS men, HS women, and college men, all of whom expressed more fear of success imagery in response to the Anne cue than to the John cue. College women did not conform to this pattern. 相似文献

Children in the third, fourth, and fifth grades were asked to do three different tasks in an attempt to determine their ability to use figurative language. Results for a Composition task showed that children produced a greater number of frozen than novel figures and that the absolute level of such usage decreased over grades. Results for a Multiple Sentences task revealed that children produced more frozen than novel figures and that both showed a marked increase over grade. Results for a Comparisons task indicated that figurative language increased over grade, and that for this task children used more novel than frozen figures. Taken in conjunction with earlier work, these data suggest that children are able to use figurative language well before theycan explain the exact nature of the relationship linking elements of the figure. In Piagetian terms, this implies that children use figurative language in the stage of concrete operations but cannot explain such usage until the stage of formal operations.This research was supported in part by Grant PEG-4-71-0066 from the Region IV Office of Education. 相似文献

An experiment was designed to investigate the locus of persistence of information about presentation modality for verbal stimuli. Twenty-four Ss were presented with a continuous series of 672 letter sequences for word/nonword categorization. The sequences were divided equally between words and nonwords, and each item was presented twice in the series, either in the same or in a different modality. Repetition facilitation, the advantage resulting from a second presentation, was greatest in the intramodality conditions for both words (+re responses) and nonwords (?ve responses). Facilitation in these conditions declined from 170 msec at Lag 0 (4 sec) to approximately 40 msec at Lag 63. Facilitation was reduced in the cross-modality condition for words and was absent from the cross-modality condition for nonwords. The modality-specific component of the repetition effect found in the word/nonword categorization paradigm may be attributed to persistence in the nonlexical, as distinct from lexical, component of the word categorization process. 相似文献

According to the theory of objective self-awareness (Duval & Wicklund, 1972), the concept of generalized drive is unnecessary, its explanatory function having been replaced by the concepts of self-evaluation and desire to be “correct”. An experiment was designed to compare alternative predictions from the drive and self-awarencess theories. Subjects listened to music in the presence of a mirror and, at another time, not in the presence of a mirror. The effect of self-consciousness on several habitual behaviors related to smoking was assessed. It was known that the subjects believed the number of cigarettes one should smoke “ideally” was significantly less than the number they actually smoked. Hence, the theory of objective self-awarencess predicts decreased smoking in the presence of the mirror, while a drive theory interpretation of self-consciousness predicts the opposite. Results generally supported the drive theory. 相似文献

It is generally recognized that the ability to contemplate and communicate about the knowledge, beliefs, and goals of oneself and others is a benchmark of human cognition. Yet, little is known about the beginnings of this ability, in large measure because methods for accurately assessing very young children's ability have been unavailable. Here we present the results of using a method of convergent analyses of naturally occurring speech to assess the young child's ability to contemplate and communicate about mental state. The first study describes the frequency and function of verbs of mental reference such as think and know in the speech of one child from 2;4 to 4;0. The second examines shorter samples of speech collected from 30 two-year-olds over a 6 month period. Results from both studies suggest that the earliest uses of mental verbs are for conversational functions rather than for mental reference. First attempts at mental reference begin to appear in some children's speech in the second half of the third year. Since most of the children studied exhibited the linguistic knowledge necessary to make reference to mental states, we conclude that the absence of such reference earlier suggests that still younger children lack awareness of such states, or at the very least, an understanding of their appropriateness as topics of conversation. 相似文献

The pooling of information from simultaneous, spatially congruent auditory and visual stimuli is examined in a signal detection task. The paradigm used permits discrimination among a number of models of the decision mechanisms involved in processing multiple component stimuli. Parameter-free predictions are presented for the weighted integration model and for three versions of the independent decisions model. The data support an independent decisions model of the bimodal detection process in which attention is shared equally between modalities. 相似文献

Kindergarten, second-grade, and fourth-grade children (6, 8, and 10 years of age, respectively) were asked to recall letter sequences on a task that required the use of: (a) a verbal strategy; (b) a positional strategy; or (c) either strategy. Additional trials, allowing either strategy, were interspersed among those requiring a verbal or positional strategy; strategy use was determined from performance on these interspersed trials. The results show that children at all grade levels attempted to use a task-appropriate strategy. Performance on the verbal task showed a more marked developmental increase than did performance on the positional task. A second experiment replicated the first with the interspersed trials removed. A third experiment was designed to determine whether letter names interfered with older children's efficient use of a positional strategy. Even with this source of interference removed, the developmental pattern of Experiments 1 and 2 was replicated. There was a Sex by Condition interaction in Experiments 2 and 3 which showed that males do better in the condition requiring a positional strategy, and females do better in the condition requiring a verbal strategy. 相似文献

Young children's apparently sophisticated understanding of language is explained by a simple heuristic which produces responses fortuitously appropriate to many of the messages directed to them. Specifically, the strategy recruits action responses to language unless some element, either linguistic or nonlinguistic, indicates otherwise. Two experiments tested for the existence of the heuristic by examining the responses of children, 19–34 months of age, to sentences susceptible of more than one interpretation. In the first experiment such sentences were spoken in as neutral a context as possible. In the second, the same sorts of sentences were presented in contexts supporting either action or informing responses. The results of both experiments indicate that young children interpret and respond to language in terms of an action-based strategy. Moreover, the observed effects of context show that even young children engage in a continuous, context-sensitive process of interpretation. The data are discussed with regard to speech act theory and its role in a developmental theory of understanding. 相似文献

The verbal helping skills of human service paraprofessionals in a youth service agency were studied. Workers who had previously completed a 10-week systematic training program in basic helping skills were compared to untrained volunteer staff. Using simulated helping interviews, it was found that training made a significant impact on trainees' verbal helping responses. Skill level was maintained at a 2-month follow-up for certain responses whereas others returned to pretraining levels. Trainees were found to use significantly more "helpful" responses than volunteers. The need for training even carefully selected paraprofessionals is discussed. 相似文献
