川金丝猴社会行为模式的观察研究

川金丝猴(Rhinopithecus roxellanae)是我国特有的灵长类动物。本文记述了两个人工饲养繁殖笼内雌雄成年和亚成年川金丝猴成员在社会交往中的各种行为模式。同时记述了各种行为模式发生时的社会情境和所涉及的成员,从而了解各种行为模式的社会含意。社会行为有攻击,作威,屈服,和解和友谊四大类,其中共包括17种不同模式的社会行为节目。     

刺激结构对视觉定位的影响

本实验采用多点定位作业,结合部分报告法,研究视觉刺激的整体结构对定位成绩的影响。所呈现的刺激为1、2、3或4个颜色点。其中2、3、4点刺激分别是直线、正三角形和正方形。结果发现,当呈现时间较长时,1点和2、3、4点的定位误差无显著差异。但是1点的定位反应时却显著少于2、3、4点。这提示出现视觉定位的结构效应。而当呈现时间较短时,却没有这种结构效应。实验还发现,这种结构效应并不因刺激结构的不同而有区别。     

心理理论的比较认知研究

非人灵长类的心理理论是比较认知研究的重要内容,它对于揭示心理理论的起源和本质,具有重要的意义。该文综述了近年来有关心理理论比较认知的现场观察研究和实验室研究,分析了关于非人灵长类对视觉知觉经验的理解,对意图和目的的理解,以及对愿望和信念理解研究的方法和结果。许多研究关于实验设计,实验结果以及对结果的解释存在争议。如非人灵长类对意图和目的的理解,是运用心理表征,还是刺激－反应的联结,非人灵长类理解同种个体和理解人类个体的心理状态存在什么差异,实验设计是否可靠而有效地测量了非人灵长类的心理理论等。该文提出实验结果和理论解释的差异和争议,可能与研究者所持的理论假设,实验任务和设计等有关。关于非人灵长类的心理理论概念的界定,从社会生态学效度和文化差异等角度综合考虑,设计恰当的实验来考察非人灵长类的心理理论,是解决目前争议必须解决的问题,也是心理理论比较认知研究面临的困难。     

Effects of computer-based immediate feedback on foreign language listening comprehension and test-associated anxiety

This study investigated the effects of immediate feedback on computer-based foreign language listening comprehension tests and on intrapersonal test-associated anxiety in 72 English major college students at a Taiwanese University. Foreign language listening comprehension of computer-based tests designed by MOODLE, a dynamic e-learning environment, with or without immediate feedback together with the state-trait anxiety inventory (STAI) were tested and repeated after one week. The analysis indicated that immediate feedback during testing caused significantly higher anxiety and resulted in significantly higher listening scores than in the control group, which had no feedback. However, repeated feedback did not affect the test anxiety and listening scores. Computer-based immediate feedback did not lower debilitating effects of anxiety but enhanced students' intrapersonal eustress-like anxiety and probably improved their attention during listening tests. Computer-based tests with immediate feedback might help foreign language learners to increase attention in foreign language listening comprehension.     

时距加工的记忆负荷效应

为了探索非时间任务短时记忆加工对不同长度时距加工的影响是否一致,本研究采用双任务范式,操纵时距编码阶段的短时记忆加工负荷,以平均复制时距为因变量指标,考察了非时间任务短时记忆加工对1-6秒时距加工的影响。结果发现,1秒、2秒及3秒的平均复制长度不随记忆负荷的大小而变化,4秒、5秒及6秒的平均复制长度随着记忆负荷变大而缩短。这意味着非时间短时记忆对时距加工影响具有选择性。     

流动儿童主观社会经济地位与问题行为的关系:公正世界信念与社会自尊的作用

采用问卷法对北京市897名流动儿童的主观社会经济地位、社会自尊、公正世界信念和问题行为进行问卷调查,探讨主观社会经济地位与问题行为的关系,并进一步考察公正世界信念的中介作用和社会自尊的调节作用。结果发现:(1)主观社会经济地位与社会自尊、公正世界信念呈显著正相关,主观社会经济地位、社会自尊、公正世界信念与问题行为呈显著负相关。(2)公正世界信念在主观社会经济地位与问题行为的关系中起中介作用。(3)社会自尊调节主观社会经济地位通过公正世界信念影响问题行为的中介路径。社会自尊水平较高时,公正世界信念的中介作用显著; 社会自尊水平较低时,公正世界信念的中介效应不显著。     

Peak velocity as a cue in audiovisual synchrony perception of rhythmic stimuli

This study investigated audiovisual synchrony perception in a rhythmic context, where the sound was not consequent upon the observed movement. Participants judged synchrony between a bouncing point-light figure and an auditory rhythm in two experiments. Two questions were of interest: (1) whether the reference in the visual movement, with which the auditory beat should coincide, relies on a position or a velocity cue; (2) whether the figure form and motion profile affect synchrony perception. Experiment 1 required synchrony judgment with regard to the same (lowest) position of the movement in four visual conditions: two figure forms (human or non-human) combined with two motion profiles (human or ball trajectory). Whereas figure form did not affect synchrony perception, the point of subjective simultaneity differed between the two motions, suggesting that participants adopted the peak velocity in each downward trajectory as their visual reference. Experiment 2 further demonstrated that, when judgment was required with regard to the highest position, the maximal synchrony response was considerably low for ball motion, which lacked a peak velocity in the upward trajectory. The finding of peak velocity as a cue parallels results of visuomotor synchronization tasks employing biological stimuli, suggesting that synchrony judgment with rhythmic motions relies on the perceived visual beat.     

Up or Down? How Culture and Color Affect Judgments

In the Mainland China stock market, an upmarket is represented by the color red, whereas a downmarket is represented by the color green. Elsewhere, including the Chinese Hong Kong stock market, the color representations are the opposite. Three studies were conducted to examine the red‐up–green‐down effect for Mainland Chinese as well as the green‐up–red‐down effect for Hong Kong people. Study 1 showed that Mainland Chinese tended to predict greater economic growth (study 1a) and higher growth in consumption trends (study 1b) when the experimental materials were presented in red than in green, whereas Hong Kong participants exhibited the opposite tendencies. Study 2 found that Mainland Chinese implicitly associated red and green with up and down, respectively; Hong Kong people, however, implicitly associated green and red with up and down, respectively. Study 3 further indicated that Mainland Chinese were more likely to predict good outcomes when scenarios were presented in red, whereas Hong Kong participants were more likely to predict good outcomes when scenarios were presented in green. These findings suggest that culturally specific environment cues could influence human prediction and judgment. Implications for judgment generally are discussed.
