This study investigated the extent to which kindergarten children (mean age 5.8 years) allocate their processing resources selectively to the relevant components of a visual array. On each trial the child was presented with an array containing either one, two, or four items, and a verbal cue designating either one, two, or four of these items as relevant. For different groups of children the cue occurred either before or after the stimulus array, in order to investigate the stages of processing at which kindergarteners are able to initiate selection. The results indicated that kindergarteners are able to exert considerable control over the allocation of resources during the initial perceptual processing of a visual stimulus, but they have only limited ability to initiate such selective allocation in memory, after initial encoding has taken place. 相似文献

Children, ranging in ages from 7.3 to 9.6 years, were identified according to the type of schemata structure they used to recall picture sequence events. These children were then required to recall several written text passages representing four different conditions: (1) theme first paragraphs, (2) theme final paragraphs, (3) paragraphs with no theme but having thematic structure, and (4) paragraphs with no theme and no thematic structure. It was found that the manner and the amount of the child's recall were a function of how the child's schemata structure interacted with a given paragraph structure. The implications of these findings are discussed in terms of the generally unquestioned assumption that only one “ideal” text grammar is needed to describe children's schemata for processing test. 相似文献

Two experiments were conducted to investigate the development of children's cognitive maps of large-scale environments. Kindergarten (Mean Age = 5?7), second (Mean Age = 7?7), and fifth (Mean Age = 10?7) graders walked through a large model town and were then required to construct the layout of building in that model from memory. Accuracy of construction increased as a function both of developmental level and repeated encounters with the layout. In Experiment 1, the separate effects of repeatedly walking through the town and repeatedly constructing it both increased the accuracy of the children's reconstructions. In Experiment 2, walking through the environment was no more effective than merely viewing it repeatedly. Young children's accuracy in bounded space (Experiment 1) was far more accurate than their performance in unbounded space (Experiment 2), while older children's accuracy was relatively unaffected by this variable. 相似文献

Subjects with initially extreme or moderate positions (based on a median split) recorded a consonant speech under public, private, or no commitment and later received a strong, mild, or no attack on their position. Extremes were more ego-involved in terms of wider latitudes of rejection, narrower latitudes of non-commitment, and greater resistance to attack, relative to moderates. Commitment had no effect for extremes, suggesting a ceiling effect on changes in the latitudes and resistance to attack for initially high levels of ego-involvement. For moderates, commitment resulted in narrower latitudes of noncommitment, wider latitudes of rejection (greater rejection of discrepant positions), and greater resistance to attack, suggesting that commitment may elevate ego-involvement with the issue. Commitment and ego-involvement may increase the salience of one's attitude position in later situations, thereby increasing the probability of attitudeconsistent behavior. 相似文献

Published and unpublished research with the Vocational Interest Inventory based on Anne Roe's interest scheme supported separating the General Cultural area out of the RIASEC framework. It emerged as a distinct fusion of certain verbal-artistic and social tendencies, and, as an occupational group, takes social scientists away from Roe's Science group. General Cultural provides a bridge in career counseling between interests and cognitive variables because of the repeated association of CUL scores with academic achievement and persistence. 相似文献

The analysis of spinal and brainstem reflexes has been shown to be a useful method of quantifying the various inputs to motoneuron pools involved in voluntary motor control. This work is selectively reviewed as a background to a discussion of the role of the perioral reflex in lip motor control for speech. Data on the sensorimotor innervation of the lips and the static and dynamic properties of the perioral reflex are presented in support of the notions that (1) perioral reflex analysis provides a viable technique for analyzing brainstem excitability changes underlying lip muscle contraction for speech, and (2) the perioral reflex loop is an important functional element in lip motor control for speech. 相似文献

This study tested the sensitivity of J. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruence method for predicting differential outcomes in the case of subtle person-environment congruence differences. This question is relevant to engineering programs, where students with adjacent Holland orientations of Investigative (I) and Realistic (R) aspire to complete theoretically oriented engineering majors, such as electrical and mechanical engineering. It was hypothesized that high congruence (e.g., I-type student in I-type engineering major) compared to moderately high congruence (e.g., R-type in I-type major) would result in more positive educational outcomes. A preliminary analysis verified that subgroups of I- and R-type students possessed similar scores on measures of general and math aptitude. Results on both outcome measures favored the high student-curriculum congruence hypothesis. I- compared to R-type subjects demonstrated greater persistence in their initial engineering major over a 2-year period and attained higher grades. Persistence findings replicated across two separate classes of entering students, but academic performance differences were not as consistent. 相似文献
