现代心理学关于单词识别的研究——单词识别的理论模型简介

心理学家近年来的研究一致发现,单词识别受词形、语音、刺激强度、语境、词频、词义等多种因素的影响。但是,关于这些因素的作用机制,各家的看法却颇不相同。本文较详细地介绍了国外几家有代表性的理论模型。这对于我们揭示汉语词字识别的基本过程将具有一定的参考价值。     

在回忆性同一判断中汉字信息提取的研究

继《再认性同一判断中汉字信息的提取》一文之后,我们作了《回忆性同一判断中汉字信息的提取》的研究,进一步研究了在同一性判断中汉字信息的提取问题,旨在比较在回忆与再认条件下人们对汉字信息提取的特点。结果表明,在回忆条件下意同判断的反应时最长,音近其次,形似最短。形似与意同判断,音近与意同判断间反应时差异显著,音近与形似之间不显著。 与前次实验相比。在回忆条件下语音的作用提高了,但形的作用仍然很大,说明字形与字音的编码对提取语义信息都有重要作用。同时,在回忆条件下,特征干扰都大于一般分心物的作用,说明单词的各种特征都影响到汉字信息的提取。     

乳头体和隔区在大鼠条件性味觉痕迹的形成和保存中的作用

本工作是在前一工作的基础上,进一步研究分别电损毁有关回路的乳头体、隔区,对以糖精水为条件刺激。氯化锂腹腔注射引起中毒作为非条件刺激的条件性糖精厌恶痕迹的形成和保存的影响。结果表明,无论是损毁乳头体,或者隔区,对条件性糖精厌恶痕迹的形成和保存均无影响。说明在本实验条件下,这种条件性味觉痕迹的形成与保存,不依赖边缘系统的乳头体、海马、隔区这些回路的参与,这就进一步说明味觉信号的记忆确有其不同于视、听觉信号的记忆的机制的。     

速示下再认汉字的某些特征

成人和小学生在速示条件下再认汉字和双字词,结果表明,成人和小学生再认不同结构类型的汉字有共同的规律:结构上属于两边对称的字较易再认,半包围型的字较难再认。成人和小学生在再认过程中抽取汉字的特征也有共同之点:对左右结构型的字往往抽取字的右下角的笔划,对半包围型的字则往往抽取字的左上角的笔划。不同再认的方式(读出和指认)对再认的成绩有明显的差别。在指认条件下由于有视觉反馈,再认成绩大为提高。本实验的结果对识字教学和机器自动识到汉字装置的设计,可能有某些参考意义。     

Longitudinal relations among perceived parental warmth,self-esteem and social behaviours from middle childhood to early adolescence in China: Disentangling between- and within-person associations

Although several studies have addressed the relations between perceived parental warmth and social behaviours, few have distinguished their between- and within-person effects or explored their within-person mediating mechanisms. This study examined the transactional relations among perceived parental warmth (i.e. maternal warmth and paternal warmth), children's self-esteem and children's positive/negative social behaviours (i.e. prosocial behaviour and delinquent behaviour) along with the mediating role of self-esteem after disentangling between- and within-person effects. A total of 4315 Chinese elementary children (44.9% girls; M_age = 9.93 years, SD = 0.73) completed relevant measures on four occasions employing 6-month intervals. Results of random-intercept cross-lagged panel models showed that (a) perceived parental warmth reciprocally and positively predicted prosocial behaviour and self-esteem; (b) perceived paternal warmth reciprocally and negatively predicted delinquent behaviour; (c) self-esteem reciprocally predicted prosocial and delinquent behaviour; (d) perceived maternal warmth reciprocally and positively predicted prosocial behaviour through self-esteem; (e) perceived parental warmth reciprocally and negatively predicted delinquent behaviour through self-esteem; and (f) perceived maternal and paternal warmth differed in their relations with prosocial and delinquent behaviours through self-esteem. These findings illuminated the complicated longitudinal within-person interactions among perceived parental warmth, self-esteem, and social behaviours, the specific mediating mechanism of self-esteem, and the differing results associated with perceived maternal and paternal warmth, all of which yield significant implications for assessments and early interventions aimed to promote positive social behaviour.     

Dehumanization of women and men in elective abortion: A preregistered replication in China

Although abortion in China has been legalized for several decades, it is still controversial and the woman and man involved are at risk of being stigmatized. The current research replicated two studies conducted in Italy by investigating how the abortion decision of the woman and man influence received moral outrage, dehumanization, and perceptions of female professional competence. Study 1, which only included female participants, found higher moral outrage toward a woman having an abortion when the pregnancy was depicted as referring to a “child” (vs. “foetus”), and higher dehumanization of the woman in terms of human nature. Study 2, which included both male and female participants, and clarified responsibility for the abortion decision with respect to the woman and the man, revealed higher moral outrage and a reduction in the attribution of human uniqueness to the man, and of human nature to both the woman and the man. Moral outrage mediated dehumanization when participants had low positive attitudes toward abortion in Study 1 and high positive attitudes in Study 2. Both studies showed a negative impact of the decision to have an abortion on the woman's perceived traditional professional competence. The results generally align with the findings from Italy and yield some practical implications on reducing abortion stigma. Future abortion stigma research should consider more gender-related factors.     

Factor structure of the mobility inventory for agoraphobia: A validational study with australian samples of agoraphobic patients

This study examines the factor structure of the Mobility Inventory for Agoraphobia and attempts to validate the inventory, using an Australian sample of agoraphobic patients, by comparison with other scales. One hundred twentyfour panic disorder with agoraphobia patients were studied. Factor analysis showed that a two-factor solution was the most suitable both when subjects were accompanied (accompanied condition) and when alone (alone condition). Factor I represented public, crowded, or social situations including department stores, supermarkets, restaurants, theaters, and panics and social gatherings. Factor II reflected enclosed or riding situations such as elevators, parking garages, enclosed spaces, and riding in subways or airplanes. These two factors accounted for 46.6% and 44.3% of the variance on the accompanied condition and the alone condition, respectively. The Mobility Inventory was significantly correlated with the Agoraphobia factor of the Fear Questionnaire and the Social Avoidance and Distress scale. These results indicated that the Mobility Inventory is a valid instrument to measure agoraphobic behavior.     

汉字词特征语义提取的实验研究

本研究运用语义判断的方法,对汉字词特征语义的提取做了初步的探讨,被试是28名大学生。实验结果表明,汉字形声字的义符在汉字词定义特征语义提取中有重要作用,在义符与词义一致时,能加速词的定义特征语义的提取。义符对词的特有特征的语义提取无作用,而特有特征的强度能很好地预测提取时间。本研究还发现,词的熟悉性和该词距其上属的语义距离对词的定义特征的语义提取亦有重要影响。     

句子理解的实验研究

在三种不同的条件下,对人验证句子的过程作了比较研究。结果表明,无论在哪种条件下,验证不同类型句子的时间模式是一致的。在句子-图形验证任务中,不管这些图形是抽象的符号还是与常识有关的具体事物的图形,其加工所需的时问基本上是相同的。但是,句子-常识验证所需的时间,要比句子-图形验证的时间明显地短。实验还表明,否定词在句中的位置,对句子的理解有一定的影响。
