影响9点问题解决的关键行为

在已有研究的基础上,作者提出划出第三条线是解决9点问题关键行为的假设,并设计了三个实验来验证假设.结果表明:任意两条线的提示训练使9点问题的解决率接近或达到100%,因而,提示两条线不能被看成是解决9点问题的关键行为;而提示划出第三条线的训练使9点问题的解决率明显高于提示其它任何一条线训练的效果,可以被认为是解决9点问题的关键行为;能够引导被试划出第三条线的训练使9点问题的解决率明显提高.     

生育价值观的理论构建及问卷的初步编制

通过文献综述、开放式调查、专家咨询和小样本测试的统计分析等提出了生育价值观的理论构想,以此为基础自编了育龄青年生育价值观问卷,并对正式问卷调查结果进行了探索性因素分析和验证性因素分析,结果表明：生育价值观是一个多层次和多维度的体系,包括3个二阶因素和9个一阶因素。该研究所构建的生育价值观理论结构比较合理,初步编制的量表需修订和完善。本研究可以为继续探讨人们的生育价值观特征提供有意义的基础。     

表面特征和结构特征在故事类比通达中的作用

在基于相似性的迁移研究中,表面特征和结构特征在类比提取过程中的作用是研究者关注的中心课题。自20世纪90年代以来,不同的研究者在故事类比通达研究的基础上,得出有关表面特征和结构特征的作用的不同结论。文章以表面特征和结构特征的概念为切入点,主要介绍表面特征和结构特征在故事类比通达中的作用的理论分歧与类比通达模型,指出当前的研究中存在的问题,并提出新的类比通达研究的框架。     

The emotional attentional blink is robust to divided attention

The emotional attentional blink (EAB) refers to a temporary impairment in the ability to identify a target when it is preceded by an emotional distractor. It is thought to occur because the emotional salience of the distractor exogenously captures attention for a brief duration, rendering the target unattended and preventing it from reaching awareness. Here we tested the extent to which the EAB can be attenuated by inducing a diffuse top-down attentional state, which has been shown to improve target identification in an analogous attentional phenomenon, the attentional blink. Rapid sequences of landscape images were presented centrally, and participants reported the orientation of a ± 90° rotation of a landscape target. To induce a diffuse state of attention, participants were given a secondary task of monitoring for the appearance of a colored dot in the periphery. We found that emotional distractors impaired target recognition performance to comparable extents, regardless of whether or not participants concurrently performed the peripheral-monitoring task. Moreover, we found that performance of the secondary task led to an impaired ability to ignore neutral distractors. Subjective ratings of target vividness mirrored the behavioral accuracy, with frequent reports of intermediate levels of vividness suggesting that the EAB might impair target visibility in a graded manner. Our results demonstrate that the EAB is robust to manipulations of top-down attention, suggesting that the temporary capture of attention by emotionally salient stimuli involves processes that are distinct from those that produce the attentional blink.     

耳机传送双重听觉信号的知觉特点研究

本研究探讨了耳机以叠加法和分离法传送双重听觉信号的知觉特点.实验结果表明(1)响度感觉是听觉中枢对同一信号的双耳输入强度加工整合的结果;(2)信号间的中枢干扰作用比外周干扰作用要小.前一论点在对三维虚拟听觉显示研究中也是应十分注意的.     

Vaginal scent marking: effects on ultrasonic calling and attraction of male golden hamsters

Male hamsters were tested for their responses to areas that had been scent marked by intact or vaginectomized females to determine the effects of naturally deposited vaginal secretions on male behavior. In the first experiment males produced more ultrasonic courtship calls when investigating areas marked by intact females than areas scented by vaginectomized females, demonstrating that vaginal marks facilitate such calling. In a wind-tunnel preference test situation in which scent-marked alleys and clean alleys served as sources of odor, males approached the scented alley first if it had been freshly marked by intact females but not if it had been scented by vaginectomized females or other males. Thus, the odors of vaginal marks are sufficient to attract males over short distances. After males entered these alleys they showed a preference for odors of both intact and vaginectomized females over no odors, but still spent significantly more time investigating the odors of intact females than those of vaginectomized females. These experiments indicate that vaginal secretions are one of the primary cues that elicit male courtship calling, and the small quantities of vaginal secretions deposited by females in vaginal marks are sufficient to elicit ultrasonic calling and attract males over short distances. Thus it is likely that vaginal scent marking and ultrasonic calling by females interact to facilitate attraction and location of mates during courtship.     

三国四城市小学儿童数学成绩的比较研究——跨文化研究之一

本研究是中国科学院心理研究所和美国密西根大学的协作项目。数学团体测验是整体研究项目的一部分。这一研究的目的是比较在不同文化背景下北京(中)、芝加哥(美)、仙台(日)和台北(中)小学儿童的数学成绩。其结果表明:亚洲学生的成绩显著高于美国儿童的成绩。我们试将美国教材同其它国家的教材进行比较,已初步看出,教材讲授的时间可能是影响中国儿童成绩的重要因素之一。学生的学习态度可能是影响儿童成绩的另一因素。其它方面如家庭条件、母亲的观念、教师的教学风格以及课堂的组织形式都可能影响儿童的学习成绩。我们对此将陆续提出报告。     

肢体伤残者心理康复的试探性研究

三年来,根据接待配装假肢及康复治疗伤残病人的实际情况,我们选择了感觉、知觉和记忆三个项目,进行了测定,即:(1)伤残部位和对应部位的两点阈值测定;(2)装戴假手后提重差别阈限的测定;(3)再认能力测定。结果表明,这些测定对伤残病人的康复治疗和心理评定都有一定的参考价值。     

Long-delay taste aversion learning in an unpoisoned rat: Exposure to a poisoned rat as the unconditioned stimulus

M. J. Lavin, B. Freise, and S. Coombes (Behavioral and Neural Biology, 1980, 28, 15–33) have shown that if two rats consume a flavored solution and one is poisoned, the unpoisoned partner will also exhibit a flavor aversion during a later preference test. Experiments 1 and 2 showed that a sufficient condition for obtaining this aversion is that the poisoned partner be present with the unpoisoned rat after it has consumed the flavored solution. It is not necessary that the poisoned partner be present when the flavored solution is consumed or indeed have had any exposure to the flavored solution. Experiment 3 showed that the unpoisoned partner can exhibit a flavor aversion when there is a temporal gap of as long as 6 hr between consumption of the flavored solution and exposure to the poisoned rat.
