恒河猴在繁殖笼内的等级结构

有关非人灵长类社群结构的问题,国外已多有研究。许多学者认为无论在野外,或是在捕后(笼养)条件下进行观察都发现只要有几只动物在一起,形成一个群,那末群内的个体之间必然形成等级关系,而这种等级关系是线性排列的。换句话说,如果一群有A、B、C、D、E五只动物的话,它们的等级关系就是这样排列的:A>B>C>D>E。     

A comparison of the codeswitching patterns of aphasic and neurologically normal bilingual speakers of English and Spanish

Conversational discourse samples were obtained from four aphasic and four neurologically normal Hispanic bilinguals in monolingual English, monolingual Spanish, and bilingual contexts to identify codeswitching patterns. Analysis of the samples based on the Matrix Language Frame (MLF) Model (Myers-Scotton, 1993a) revealed consistent matching of the language context by the aphasic and normal subjects. The aphasic subjects demonstrated a greater frequency of MLF constituents and codeswitching patterns not evident in the speech samples of the normal subjects. Results suggest an increased dependence on both languages for communication following neurological impairment.     

3~5岁儿童的交换行为研究

设计了一个贴近现实的玩具交换任务,考察3~5岁儿童在玩具交换情境中的行为特点及其利用社会知觉信息指导交换选择的能力,被试为91名3~5岁儿童,男女各半。结果发现,随着年龄增长,儿童在交换任务中得分有显著增长,通过率由43.3%（3岁组）上升到85.5%（5岁组）。儿童对成功的交换行为的解释逐渐偏向于参与交换的人物而非交换的物品。这表明儿童利用社会知觉信息进行行为决策的能力在3~5岁间有明显的发展。     

成人与中学生科学概念形成过程的四个对比实验

以一组非人工的、自然的科学概念(“反作用力”、“机械能守恒”、“熵”和“场”)为学习内容,分别以成人和中学生为被试,实验研究成人和中学生科学概念形成过程的异同。结论如下：(1)成人与中学生科学概念形成过程均分为振荡渐进期、高原期和突变期。(2)成人的振荡渐进期较长;中学生的振荡渐进期较短且振荡特征比较明显。(3)成人的高原期出现较晚,但持续较长;中学生的高原期出现较早,但持续较短。(4)中学生的突变期的跨度随概念的抽象程度提高而越来越大。     

Self-regulated profiles and academic achievement

To date, research on the relation between learning self-regulation and academic achievement has generally show disparate results. This work intends to look into this relation from a new perspective, which consists in classifying the students as more or less self-regulated depending on diverse indicators and using cluster analysis. The aim of this work was to identify the possible self-regulated learning profiles in a sample of university students. By means of stepwise linear regression analysis, we determined which of the selected variables better predicted metacognitive self-regulation. Then, three significantly different self-regulated learning profiles were obtained by two-step cluster analysis with those variables. Lastly, ANOVA was used to analyse the relation between the self-regulated learning profiles and academic achievement. The implications of these data for the educational practice at university are discussed.     

Speech perception development in children with dyslexia

Several studies have indicated that dyslexics show a deficit in speech perception (SP). The main purpose of this research is to determine the development of SP in dyslexics and normal readers paired by grades from 2nd to 6th grade of primary school and to know whether the phonetic contrasts that are relevant for SP change during development, taking into account the individual differences. The achievement of both groups was compared in the phonetic tasks: voicing contrast, place of articulation contrast and manner of articulation contrast. The results showed that the dyslexic performed poorer than the normal readers in SP. In place of articulation contrast, the developmental pattern is similar in both groups but not in voicing and manner of articulation. Manner of articulation has more influence on SP, and its development is higher than the other contrast tasks in both groups.     

Believing literally versus symbolically: values and personality correlates among Spanish students

Values and personality correlates of general religiousness may be specific and even different when one distinguishes between Exclusion versus Inclusion of Transcendence and Literal versus Symbolic thinking on religious issues. In the present study, 133 Spanish students were administered the Schwartz Value Survey, the NEO‐PI‐R and the Post‐Critical Belief scale. Exclusion versus Inclusion of Transcendence reflected the conflict between openness to change (and hedonism) and conservation values; it was positively related to agreeableness and conscientiousness, and negatively to universalism and openness to experience. Literal versus Symbolic thinking reflected the conflict between self‐enhancement and self‐transcendence values, and was associated with high openness to experience. Results partially replicated previous studies in Belgium, with some differences that were rather in line with previous meta‐analyses. The discussion also points out cultural and contextual specifics.     

Spanish adaptation of the Stepparent Role Strain Index

Stepparent role strain refers to the fragile position of these family members in stepfamilies due to the lack of clear social expectations about their roles. This ambiguity facilitates family conflict and a lack of stepparents' integration into the family system. The aim of this paper is to adapt a pioneer measure of stepparent role strain--the Stepparent Role Strain Index of Whitsett and Land (1992)--in a Spanish sample and to analyze its construct validity. The final instrument is made up of 26 items which have good internal consistency (alpha = .89) and an underlying six-factor structure, explaining 64.50% of the total variance.
