The parents of 41 children who had been given an individually-administered intelligence test were contacted approximately 19 months after testing. The sample included 20 parents who had learned their child had an Average IQ (children'smeanIQ = 100.8) and 21 parents who had learned their child had an Above Average IQ (children'smeanIQ = 130.0). Parents of Average IQ children were less accurate in their memory of test results, and they and their children experienced fewer positive consequences from IQ testing than Above Average children and their parents. Children with Above Average IQ experienced extremely low frequencies of sibling rivalry, conceit or pressure, and they and their parents experienced increased pride and/or self-confidence as a result of the IQ testing. The results as a whole suggest that parents of Average IQ children may need more psychological support during the parent informing process than parents of Above Average IQ children. 相似文献

To what extent are models of memory general, in that they may be applied to children or to other cultural groups? In an attempt to answer this question, two experiments were undertaken in Morocco to investigate various cultural and experiential antecedents to memory development. A total of 384 children and young adults, ranging in age from 6 to 22 years, were tested in a design that contrasted schooled and nonschooled children in urban and rural environments. Three additional groups of subjects—Koranic students, Moroccan rug sellers, and University of Michigan students—were also studied because it was hypothesized that each might have particular “culture-specific” memory skills as a function of previous experience.A serial short-term recall task was used in Experiment I. Results showed that the recency effect or short-term store was generally invariant with age or experience. Control processes appeared to be a function of age, but only when coupled with schooling, and, to a lesser extent, urban environment. In Experiment II, a continuous recognition memory task was given with black and white photographs of Oriental rugs as stimuli. Forgetting rates were generally invariant with age and experience, while the acquisition parameter seemed to vary as a function of specific cultural experiences. Data from the three additional groups were useful in supporting the hypothesis of culture-specific memory skills.From Experiments I and II, and previous research, it was hypothesized that structural features of memory (e.g., short-term store and invariant forgetting rates) may be universal, while control processes or mnemonics in memory are probably culture-specific, or a function of a variety of experiential and cultural factors that surround the growing child. 相似文献

Subjects aged 8, 10, 12, and 18 years participated in two visual search tasks. In one task the rate of visual search reflected the speed of preattentive localization processes, and in the other task it additionally reflected letter identification process speeds. The data revealed that localization processes become faster from ages 8 to 12 and remain stable thereafter, and that identification processes increase in speed primarily from ages 8 to 10. Performance on a subsequent recognition task indicated that subjects of all ages were employing a similar encoding strategy during visual search. Furthermore, subjects retained general information about the features of irrelevant background letters even though recognition accuracy for more specific information about letter names was not high. The finding that localization and identification processes have different rates of development confirms the hypothesized distinction between the two and implies that developmental studies of visual scanning speed must focus upon changes in the relationships among various processes or component skills throughout development. 相似文献

Daily-self-ratings of mood and state were obtained for approximately 120 days of observation from five pregnant subjects. Measurements were based on a total pool of 75 adjectives culled from the literature to represent eight dimensions of affect established in primarily cross-sectional studies. The data were analyzed in a P-technique factor analysis context to determine both the extent to which interindividual differences and intraindividual variability concepts were interchangeable and how general such intraindividual variability concepts were among different subjects. Although evidence was found that subjects construe many adjectives differently, for dimensions such as Energy, Well Being, Fatigue, and Concentration, the data indicate that cross-sectionally and longitudinally based personality concepts exhibit a fair degree of convergence. 相似文献

Data from seven studies involving 849 high school and college students were used to test the recessive X-linked genetic model prediction that the square of the proportion of men who perform accurately on the water-level task is equal to the proportion of women who perform accurately. Goodness-of-fit tests showed that this prediction was confirmed for each sample. A model with a single estimate of gene frequency accounted for all the data when a classification error parameter was incorporated into the X-linked model. In both models the gene frequency parameter was about . 相似文献
