计算机控制心理学实验过程的计时误差分析

计算机在控制心理学实验过程中,可能引入各种潜在的计时误差,特别在短时呈现各种实验刺激时,有些误差是不应忽略的。本文重点分析屏幕刷新率对实验设计的限制及可能产生的计时误差和解决方法。     

教育因素对认知功能年老化过程的影响

应用言语－操作和人机对话两种方式共１２项作业,完成年龄和教育因素对认知功能影响的研究,被试共７３４人,４６－７５岁．结果表明：（１）年龄和教育因素对认知成绩的影响因作业而异,分别为年龄影响明显（图象自由回忆和无意义图形再认）、教育因素影响明显（卡片分类、图象分类和矩阵填图）、年龄和教育因素影响均明显（符号数字、词对联想学习、听觉和视觉数字广度）或均不明显（心算）．（２）四项非词语性作业速度明显受年龄和教育因素的双重影响．     

Effects of parental alcoholism and life stress on hispanic and non-hispanic caucasian adelescents: A prospective study

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.

临床经验对诊断的双重作用及改造

文中用辩证唯物主义的观点,阐述了临床经验的定义、来源及指导实践过程中的意义,指出其具有促进诊断和引起误诊的双重作用,并用临床病历例子详细说明其双重作用的形式、导致结果及产生的原因。指出临床经验的双重作用在临床工作中的重要性及局限性,提出对经验的改造完善途径,以能充分表现出其促进诊断的作用,而最大限度降低其导致误诊的程度,发挥在临床工作中的良性作用。     

Predictive testing and oncogenes

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?     

合作学习对小学生同伴关系、成就动机和成就影响的研究

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。     

Differences in influence between pitched-from-vertical lines and slanted-from-frontal horizontal lines on egocentric localization

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.     

与年龄相关的认知速度减慢及学习改善过程

该工作应用人机对话方式完成心算、符号数字、数字鉴别和计数四项作业认知速度年老减慢及学习改善过程的研究,被试３５０人,４６—７５岁。研究结果表明：四项认知作业速度随年老进行性减慢;然而,老年人经学习训练认知作业速度可明显改善。上述变化程度与作业所需时间有密切关系,提示年老过程中枢信息加工过程速度的减慢快于外周感觉─运动过程速度的减慢,学习改善作用也可能主要是中枢过程速度的提高。
