Three hundred and eight primary level boys and girls from the Madang, North Solomons, and Southern Highlands Provinces of Papua New Guinea were tested for conservation of number, length, quantity, and area. School grade, and age were related to performance in some cases, though sex had little effect. There were significant differences between the language-culture groups tested on three of the four conservation tasks. Since there was little consistency of performance over the four tasks, it was suggested that explanations of the variations of cognitive performance found within Papua New Guinea, and between Papua New Guinean groups and others may need to give attention to specific characteristics of each group's environment.  相似文献

A procedural theory of eye movement that accounts for main features of the stochastic behavior of eye-fixation durations and direction of movement of saccades in the process of solving arithmetic exercises of addition and subtraction is presented. The best-fitting distribution of fixation durations with a relatively simple theoretical justification consists of a mixture of an exponential distribution and the convolution of two exponential distributions. The eye movements themselves were found to approximate a random walk that fits rather closely in both adult and juvenile subjects the motion postulated by the normative algorithm ordinarily taught in schools. Certain structural features of addition and subtraction exercises, such as the number of columns, the presence or absence of a carry or a borrow, are well known to affect their difficulty. In this study, regressions on such structural variables were found to account for only a relatively small part of the variation in eye-fixation durations.  相似文献

Stimulus generalization is suggested as an alternative method for examination of the "novelty" problem in motor learning. These experiments demonstrated that stimulus generalization occurs using simple movements as stimuli. The phenomenon of the "peak shift" in post-discrimination generalization gradients was also examined. The first experiment demonstrated that a peak shift occurred using linear movements as stimuli and that the magnitude of the peak shift increased as the difference between the training stimuli decreased. The second experiment showed similar results when the stimuli consisted of a range of movements rather than single movement length. The final experiment provided evidence that perception of movement length is influenced by the magnitude of an immediately preceding movement. The relevance of these studies to current motor-learning theory is discussed.  相似文献

An inservice training workshop for employment counselors on the skill of job development is reviewed. Evaluations proved there is a need for additional inservice training on job development skills, including follow-up, marketing, using outside resources, matching employer needs with client capabilities, speaking before groups, effective verbal communication with employers, and overcoming objections.  相似文献

The influence of the control of movement and viewing while exploring a novel large-scale environment was assessed. Forty kindergarteners and forty second grade children served in four activity conditions that represented the factorial combination of movement (self vs adult directed) and viewing (self vs adult directed). A significant grade level X movement X viewing interaction revealed that when kindergarteners directed their own movement, estimates of interlocation distances were equivalent whether viewing was self or adult directed. If movement was directed by an adult, kindergarteners estimated interlocation distances more accurately if the adult also directed their viewing than if the children directed their own viewing. Second grade children performed comparably across all four experimental conditions.  相似文献

A total of 985 third through sixth grade children participated in the development of a 48-item Locus of Control Scale for Children's Perceptions of Social Interactions (LOC-CPSI). Scores are based on the number of positive, negative, and total social reinforcers a child attributes to his or her own behavior (internal control). A social desirability subscale is included. Reliability coefficients were comparable to or greater than those of existing locus of control measures. Convergent validity was demonstrated by low, significant correlations with other locus of control measures. Internal scores correlated significantly with sociometric measures of popularity and predicted peer status better than other locus of control measures. Theoretical implications and potential clinical application are discussed.  相似文献

The Rokeach Dogmatism Scale and the Eysenck Personality Questionnaire were correlated with educator-reported use of corporal punishment. Respondents were from a medium-size school system in Tennessee. Results indicated that closed-mindedness, as measured by the Rokeach scale, and Neuroticism, as measured by the Eysenck Scale, were highly correlated with reported use of corporal punishment. Of the remaining two dimensions of personality measured by the Eysenck questionnaire, Extraversion was found to be moderately correlated with reported use of corporal punishment while Psychoticism showed no significant relationship. A significant negative correlation was found between years of experience in teaching and use of corporal punishment. Frequency of physical punishment used on an educator when he/she was in grades K-12 was positively correlated with reported use of corporal punishment. Heavy users of corporal punishment tended to be relatively inexperienced, close-minded, neurotic, and impulsive as compared to their peers who did not use corporal punishment.  相似文献

The SOMPA is examined in terms of the multicultural model and Mercer's justification for multiple normal distributions within that model. The philosophical basis of the approach and the environments in which any assessment strategy must function are also examined. It is concluded that multiple normal distributions are not justified based on the variance accounted for in WISC-R scores by the Sociocultural Scales of the SOMPA. The pholosophical basis of the SOMPA, the sociology of knowledge, is not considered helpful or useful in the assessment process because of internal logic problems associated with the paradigm and because it creates an artificial separation of populations. Some of the components which influence education are examined in an effort to place the SOMPA in a realistic operational environment and to contrast the complexity of that environment with the oversimplified view offered by the SOMPA.  相似文献

The following measures were obtained from 42 student volunteers: the General and the Disinhibition subscales of the Sensation Seeking Scale (Form IV), the Reducer-Augmenter Scale, and the Absolute Auditory Threshold. General sensation seeking correlated significantly with the Reducer-Augmenter Scale, r(40) = .59, p less than .001, and the Absolute Auditory Threshold, r(40) = .45, p less than .005. Both results proved general across sex. These findings, that high-sensation seekers tend to be reducers and to lack sensitivity to weak stimulation, were interpreted as supporting strength-of-the-nervous-system theory more than the formulation of Zuckerman and his associates.  相似文献
