This experiment examined the expression and effectiveness of memorization in young children. Sixty children at each of the ages 4, 5, and 6 were randomly assigned to a memory group or to one of two control groups. All of the children were told that they could play with a group of toys during a brief activity period; the children in the memory condition were also instructed to memorize a specified subset of the toys. Mnemonic mediators were identified on the basis of differences in the activity period behaviors of children given memory and play instructions. Relative to the children in the play groups, the children in the memory conditions played with the toys less; further, their use of naming and visual examination as mnemonic mediators differentiated the groups at all ages and increased with age. Only the oldest subjects given memory instructions, however, demonstrated superior recall. The relationships between activity period behavior and recall among the different conditions were explored with regression techniques. Although previous research has focused on identifying the earliest use of memory strategies, the present findings underscore the importance of examining the development of these skills. 相似文献

The effect of exploratory activity and emotional reactivity on the acquisition of active avoidance learning was assessed in rats. Four strains of rats selectively bred for a high or low degree of either of the two traits (Maudsley emotionally reactive animals, Maudsley emotionally non-reactive animals, high rearers, and low rearers) and a control strain (randombred animals) took part in the experiment. Significant differences were found between strains in the number of animals showing active avoidance behaviour. Emotional reactivity was shown to facilitate active avoidance behaviour and so did, unexpectedly, a low degree of exploratory activity. An attempt was made to explain the latter result in terms of differences in channel capacity between high and low exploring animals and the ensuing differences in attention focus on the relevant stimulus for the test situation. 相似文献

Hooded rats were conditioned to avoid drinking saccharin by following exposure to saccharin with injection of cyclophosphamide, a drug that produces visceral upset. Extinction trials were then given by presenting saccharin without cyclophosamide injections with the rats under low (10 hr) or high (23 hr) fluid deprivation. The aversion extinguished in fewer trials in rats under high deprivation. 相似文献

The relative success of influence attempts undertaken by attractive vs. unattractive fifth- and sixth-graders was investigated by giving subjects a monetary incentive contingent upon their influencing a peer's behavior. Compared to a control group which was not subject to peer pressure, three groups were successful: attractive males and attractive females with opposite-sex peers and unattractive males with same-sex peers. Attractive girls tended to be more successful than their unattractive counterparts in influence attempts directed toward peers of the opposite-sex. Unattractive males were more effective than attractive males with same-sex peers. Analysis of the influence strategies employed revealed markedly different styles of interpersonal influence, particularly between attractive males and attractive females. The former made considerably more influence attempts and were judged to be more persistent. This type of behavioral difference was not found for unattractive males compared to unattractive females. 相似文献

Several measures of the speed of information processing were related to ability factors derived from the Cattell-Horn theory of fluid and crystallized intelligence. Ninety-one college students took a battery of paper and pencil tests designed to measure four ability factors: fluid intelligence (Gf), crystallized intelligence (Gc), spatial visualization (Gv), and clerical perceptual speed (CPS). They also performed paper and pencil and computerized versions of three information processing tasks: mental rotations, letter matching, and sentence verification. Correlations among the ability measures, among the information processing measures, and between the two domains were analyzed using confirmatory factor analysis. The four ability factors were found to be largely independent in this college population. Speed of letter-matching and sentence verification were highly correlated, but neither was related to speed of mental rotation. Mental rotation speed was strongly correlated with Gv; letter matching speed was correlated with CPS; and sentence verification speed was correlated with both Gc and CPS. 相似文献

Discrimination learning and reversal problems were given to 128 children aged two and three years in which there were either two, three, six, or nine choice-alternatives per problem. The position of the correct object (either a toy car on the original problem and a ball on the reversal problem or vice versa) was varied randomly among all the possible positions, all other positions being occupied by duplicates of the incorrect object. It was found that two-choice reversal problems were much more difficult than all others. There was also a direct and monotonic relationship between ease of solution and number of choices present during reversal learning. Additional analysis inlicated that position response biases were probably responsible for this effect. 相似文献

An analysis of Geoffrey Hill's lyric poem about William Blake illuminates the relations between art, prophecy, and imperial politics across more than two centuries. Hill's poem responds to David V. Erdman's argument that Blake was resolutely, if ineffectually and sometimes secretly, opposed to war. It also establishes Hill's own cryptic but definite resistance to contemporary war and warmongers, while it mourns poetry's public powerlessness to halt the violent competition for material resources. Ignored by the majority, poetry fails to bring about the ethical social change that poets often envision. The layering of perspectives (Hill the poet and scholar writing about Erdman the scholar, who is explicating Blake the poet and artist) allows for a multidimensional interpretation of the role of poets and prophetic poetry. Despite their fury at society's deafness and greed, and frustration at their own incapacities, poets—because if they are great poets, they are prophets, too—continue to speak to their audiences about the problems of this world and about the better worlds that can be imagined. Hill's text obliquely teaches how the small success of a great poem can provide a minor note of consolation as it objects to terror and tyranny. 相似文献
