笔画类型对直立和倾斜汉字识别的影响

首次用笔画类型概念描述一种汉字整体视觉结构特征。实验采用命名范式。结果发现,汉字无论处于垂直正位下,还是处于以４５°间隔递增的七种倾斜角度下,都存在笔画类型效应。该研究还分析了线条倾斜效应和笔画类型因素在笔画类型效应中的作用     

The Epic of Evolution as a Framework for Human Orientation in Life

This article sketches what is required of a world picture (religious or nonreligious) that is intended to provide orientation in the world for ongoing human life today. How do we move from conceptions and theories prominent in the modern sciences—such as cosmic and biological evolution—to an overall picture or cosmology which can orient us for the effective address of today's deepest human problems? A biohistoricalconception of the human is proposed in answer to this question.     

Cognitive specificity and affective confounding in social anxiety and dysphoria in children

Cognitive features of social anxiety and dysphoria were examined with a design that allowed for evaluation of each state alone and in combination. From a community sample of 211 8 to 12 year olds, four groups of children were defined based on previous researcher's criteria: mixed (high socially anxious-dysphoric;n= 14), socially anxious (high socially anxiousnondysphoric;n= 14), dysphoric (non-socially anxious-dysphoric;n= 13), and control (non-socially anxious-nondysphoric;n= 14). The negative cognitive triad and negative cognitions pertaining to the self were associated with both dysphoria and social anxiety. Both dysphoric and socially anxious groups reported significantly more cognitive distortions than the control group, yet cognitive distortions of overgeneralizing and personalizing were specific to social anxiety and not dysphoria. Both dysphoric and socially anxious groups reported significantly more depressive cognitions than the control group, and evidence of cognitive content-specificity emerged only for anxiety, although there was some evidence for depressive content-specificity in the mother's ratings. The mixed group was the most dysfunctional on all of the cognitive measures. This study provided some evidence of cognitive-specificity as well as the confounding between the affective states of dysphoria and social anxiety. Methodological, theoretical, and treatment implications are highlighted.     

Orientation and lever responding in auditory discriminations in squirrel monkeys.

Head orientation during auditory discriminations was studies in squirrel monkeys using a two-lever trial-by-trial procedure. Animals were studied using auditory discriminations based on the position of the sound and on the spectral content differences between a pure tone and a noise. After the percentage of correct responses reached asymptote, head orientation was measured using videotape recordings. Orientation occurred on virtually every trial and was under the control of the position of the sound under all conditions. Lever responding was controlled by the same parameters of the sound under some conditions, and by different parameters in others. Orientation and lever responding were correlated (a level response could be predicted from the direction of orientation) when both responses were under the control of the same parameters of the sound. The two responses were uncorrelated when they were controlled by different parameters of the sound. Orientation and lever responding were not functionally related.     

An evaluation of reality orientation therapy

An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research.     

线方向判断测验在神经内,外科临床的应用与评价

对200名正常人及168例脑损害病人分别进行了线方向判断测验的测查。发现在对照组中,年龄、性别、文化水平对测验成绩均有一定的影响,尤以文化水平的影响最为显著。各病种组与对照组比较,发现脑梗塞组与脑肿瘤组成绩比外伤组和血管畸形组为差。同时还发现所有病种组右脑损害患者分数均低于左脑损害患者。     

Representations of guidance counselors,psychologists, and psychoeducators regarding psychological assessment

IntroductionSocial representations related to collaborative/therapeutic and information-gathering assessment could explain some psychological assessment practices. However, no other study has attempted to examine the actual place of these models in psychological assessment practices.ObjectiveThe goal of this study was to examine the social representations of different groups of professionals with regard to their preferred approach to psychological assessment.MethodA latent profile analysis was conducted on a sample of licensed Canadian guidance counselors (n = 382), psychologists (n = 235), and psychoeducators (n = 97).ResultsResults revealed three psychological assessment profiles, which significantly differ in terms of a few social factors. Results also showed that some psychological assessment practices differ across profiles.ConclusionThis study provides a better understanding of psychometric instruments users’ approaches to assessment and the influence of social factors.     

工作记忆的存储时间及目标时距对时间知觉的影响

本研究操作记忆信息与计时开始之间的时间间隔（ISI）和目标时距,探讨工作记忆影响时间判断的灵活性。被试首先记忆一个客体,然后在每个trial的最后判断测试刺激是否与记忆项相同;在延迟阶段,被试完成时间判断任务,即判断相继出现的两个刺激的时距哪个更长（或更短）。时间任务中的一个刺激与记忆内容完全相同,相应的另一个刺激与记忆内容在形状和颜色上都不同。重复条件下,被试忽略第一个刺激,仅完成时间判断任务。结果发现,时间间隔（ISI）短时,记忆匹配条件下的准确率更高,匹配刺激延长了知觉的时间;但随着时间间隔的增加,工作记忆匹配对时间判断的影响降低甚至消失。并且,长或短ISI,记忆任务或重复条件下,目标时距长时,记忆匹配反而缩短了知觉的时间。研究说明工作记忆对时间判断的影响是灵活的,受到注意或工作记忆等高级认知系统的调控。     

追求快乐还是追求意义?青少年幸福倾向及其对学习行为的影响

研究使用问卷调查法,以2828名中学生为对象,考察了幸福倾向对其学习目标、学习毅力、学习策略、学习投入等学习行为的影响。结果表明:(1)青少年的意义倾向对其成就目标中的掌握目标和表现趋近维度、学习毅力、学习策略和学习投入都有显著的正向预测作用,对成就目标中的表现回避维度具有显著的负向预测作用;(2)青少年的快乐倾向对掌握目标、学习毅力、学习策略和学习投入都有显著的负向预测作用,对表现趋近和表现回避有显著的正向预测作用;(3)通过意义倾向和快乐倾向两个维度可以将青少年分为四类,双高组和单高意义组的青少年在学习行为表现上最积极,双低组的青少年学习行为表现最为消极。总体来说,追求快乐还是意义会影响到青少年学习行为这一重要的发展指标,意义比快乐更能促进青少年的积极健康发展。     

不同感觉通道的节奏感知及其交互作用

节奏感知是人类独有的认知现象, 听觉在节奏加工中具有优势, 声音节奏可以更好地与肢体运动同步, 但视觉和触觉通道在节奏感知上也有着各自特点并存在广泛的交互作用。视觉通道的节奏感知较弱, 与听觉节奏同时呈现时会受到时间定位上的拉扯, 但通过加入运动信息和增强后天经验可以得到强化; 节奏刺激可以调节注意在时间上的分配使其同步化, 这种调节作用可以单通道或者跨通道地出现; 触动觉与听觉联系紧密, 人们可以通过听触通道的整合对节奏进行高级加工。
