A series of experiments was conducted to explore whether individuals can solve problems by transferring conceptual information gained from schematic pictures and to examine the mechanisms involved in this transfer process. Subjects viewed a schematic picture and then attempted to solve an insight problem to which the conceptual information from the picture could be applied. The results indicate that the degree of similarity—specifically, superficial and procedural similarity—between a source schematic picture and the target problem determined transfer performance. Discussion focuses on the relationship between these two types of similarity and the two key cognitive components involved in transferring pictorial analogies to solve problems: accessing the pictorial analogues and executing the solutions. Portions of this research were presented at the 33rd meeting of the Psychonomic Society in St. Louis, November 1992.  相似文献

Investigated ethnicity and parental alcoholism as factors that might influence the stress vulnerability of adolescents. It extended an initial cross-sectional study of this same sample by adding two annual assessments which allowed for additional cross-sectional analyses and longitudinal tests. Hispanic and Caucasian adolescents (N=306 at Time 1) completed measures of their own life stress, family conflict, and alcohol use. Their parents reported on adolescents' internalizing and externalizing symptoms. Cross-sectional analyses at Time 2, and prospective analyses involving Time 1 and Time 2 measures were, for the most part, consistent with the original study's results. Caucasian adolescents and children of alcoholic parents appeared to be more vulnerable to stress than Hispanic adolescents and children of nonalcoholic parents. Family conflict was a partial explanation for this increased vulnerability. This research was supported by National Institute on Drug Abuse Grant DA05227 to Laurie Chassin (pricipal investigator) and Manuel Barrera, Jr. (coprincipal investigator). Susan Li was supported by an American Psychological Association Minority Fellowship Award. Portions of this research were presented at the conference, “Resiliency in Families: Racial and Ethnic Minority Families in America” that was held at the University of Wisconsin, May 31–June 2, 1994.  相似文献

To explore the potential of Rational Emotive Therapy (RET) with clients of Chinese background, a brief review is conducted with respect to parallels between RET philosophy and some key components of Chinese culture and ways in which Chinese think. Arguments are advanced as to why RET is particularly suitable for use within a Chinese cultural context. Issues involved in using RET with Chinese clients are addressed including the appreciation many Chinese have for the logical and rational aspects of RET, the most appropriate type of client-counselor relationship to facilitate RET therapeutic progress, appropriate ways to dispute, and some cautionary words on the use of “emotive methods”. Areas where the RET counselor needs to be particularly sensitive to the cultural background of the client are highlighted. Charles P. Chen holds a master's degree in educational counseling and is currently a Ph.D. student and instructor in the Department of Counselling Psychology at the University of British Columbia in Vancouver, Canada. His interests include cross-cultural and multi-cultural counseling, career counseling, and group counseling.  相似文献

Case vignette: sharing unanticipated genetic information. The Questor family has experienced an unusual number of malignancies in the past two generations and has been advised by an oncologist that the p53 oncogene known as Li-Fraumeni Syndrome may be present in the family genome. The option of predictive genetic testing has been raised and several branches of the family have chosen to undergo screening to determine whether they are at risk for cancer because of the gene. Roger and Liz Questor have arranged for screening of themselves and their three children, ages 12, 10, and 7. The couple has, by all appearances, been happily married for 14 years. None of the family members are found to carry the oncogene; however, the geneticist conducting the analyses has made an interesting incidental discovery. The 10-year-old child is not the biological progeny of Roger Questor. Although the 12- and 7-year-olds are clearly the biological children of the couple, it is evident that the 10-year-old born to Liz Questor was fathered by a person other than Roger. What are the ethical obligations of the geneticist with respect to any sharing or disclosure of the information that has been discovered incidentally? What course of action, if any, do you recommend?  相似文献

以实验鉴定了常规的启动效应计量方法的有效性程度,并为客观地计量启动效应,创用了“超意识广度法”、“二次比较法”等.结果发现:(1)如被试数量较少,以不同补笔率为“基线值”所求得的启动效应之间发生显著差异的可能性存在;(2)超意识广度法能克服“阈下呈现刺激法”“分散注意法”的不足,为内隐记忆提供有利的识记情境;(3)“二次比较法”能为正常人内隐记忆的存在提供更为直接、可靠的证据,并能客观、精确地计量启动效应。  相似文献

合作学习对小学生同伴关系、成就动机和成就影响的研究   总被引:12,自引:0,他引:12  
旨在探讨在我国开展合作学习教学的可行性,以及合作学习对小学生同伴关系、成就动机和成就水平的影响,运用自然实验和测量相结合的方法,选择了北京师范大学实验小学三年级两个班进行实验研究,其中一个班为实验班(n=35),另一个班为控制班(n=37).实验为期三个月。结果表明:合作学习在小学教学中不但是可行的,而且效果较为显著;合作学习对同伴关系的改善有着积极的影响,学生间的接纳度和被接纳度都有普遍的提高;合作学习在较大程度上激发了学生的成就动机水平,学生对合作学习的课程兴趣明显提高.成绩较差的学生表现得更为明显;合作学习对提高学生的学习成绩有一定的促进作用。  相似文献

The visual field exerts powerful effects on egocentric spatial localization along both horizontal and vertical dimensions. Thus, (1) prism-produced visual pitch and visual slant generate similar mislocalizations of visually perceived eye level (VPEL) and visually perceived straight ahead (VPSA) and (2) in darkness curare-produced extraocular muscle paresis under eccentric gaze generates similar mislocalizations in VPEL and VPSA that are essentially eliminated by introducing a normal visual field. In the present experiments, however, a search for influences of real visual slant on VPSA to correspond to the influences of visual pitch on VPEL failed to find one. Although the elevation corresponding to VPEL changes linearly with the pitch of a visual field consisting of two isolated 66.5°-long pitched-from-vertical lines, the corresponding manipulation of change in the slant of either a horizontal two-line or a horizontal four-line visual field on VPSA did not occur. The average slope of the VPEL-versus-pitch function across 5 subjects was +0.40 over a ±30° pitch range, but was indistinguishable from 0.00 for the VPSA-versus-slant function over a ±30° slant range. Possible contributions to the difference between susceptibility of VPEL and VPSA to visual influence from extraretinal eye position information, gravity, and several retinal gradients are discussed.  相似文献
