‘Women are Bad at Math,but I'm Not,am I?’ Fragile Mathematical Self‐concept Predicts Vulnerability to a Stereotype Threat Effect on Mathematical Performance

The present research reports the results of three studies showing that individuals with a fragile self‐concept in the domain of performance are particularly vulnerable to stereotype threat effects. Specifically, women who explicitly described themselves as rather mathematical but whose implicit self‐concepts contradicted these claims were vulnerable to stereotype threat effects on mathematical performance. This effect was robust across three studies, independent of the subtleness or content of the stereotype threat manipulation. Additionally, it was shown that the effect was mediated by anxious worrying (Study 3). Copyright © 2012 John Wiley & Sons, Ltd.     

Exploring the dynamics of design fluency in children with and without ADHD using artificial neural networks

The neuropsychology of attention deficit/hyperactivity disorder (ADHD) has been extensively studied, with a general focus on global performance measures of executive function. In this study, we compared how global (i.e., endpoint) versus process (i.e., dynamic) measures of performance may help characterize children with and without ADHD using a design fluency task as a case study. The secondary goal was to compare the sensitivity of standard versus connectionist statistical models to group differences in cognitive data. Thirty-four children diagnosed with ADHD and 37 children without ADHD aged 8–11 years old were tested on the Five-Point Test. The continuous process measure of performance, indexed as the number of produced designs at each consecutive 1 minute interval during 5 minutes, was analyzed against the discrete process measure, that is, the number of designs between first and last intervals and the standard global performance measure of total number of produced designs. Results show that the continuous process measure distinguished the two groups better than the two other measures. The detailed observation of production patterns revealed a decreasing linear trajectory in children without ADHD that contrasts with the flat, but fluctuating productivity pattern of children with ADHD. With regards to the second goal, results show that the connectionist and standard methods are equally sensitive to group differences for the three types of measures. This illustrates the utility of quantitative process measures together with the connectionist method in neuropsychological research and suggests great potential for a dynamical approach to cognition.     

6～14岁儿童对想象物的文字与图画描述

本研究采用开放式问卷法,通过调查810名6-14岁儿童头脑中想象物的文字与图画描述,考察了儿童想象发展的特点。结果发现：(1)儿童对想象物的文字与图画描述可以分划分为3种水平：表象的记忆水平、表象的再造水平和表象创造水平。其中,对想象物的文字描述水平,年龄发展趋势明显,从小学一至二年级之间和四到五年级之间的发展变化最大;而对想象物的图画描述水平,年龄发展趋势不明显。(2)根据儿童对想象物的文字描述和图画描述的发展的匹配程度,可以把儿童的想象发展分为3种类型：文字与图形符号均衡发展型、文字符号型和图形符号型。     

学习不良儿童社会性发展特点的研究

对211名10—15岁学习不良儿童社会性发展特点的研究表明,学习不良儿童在本研究确定的社会交往、自我概念和行为问题诸维度上具有独特的年龄和性别特点。学习不良女孩的社会性发展水平略高于学习不良男孩;随年龄递增．学习不良儿童的社会性发展水平不断得到提高,但其在不同年龄阶段的特点则有所不同。同时．学习不良儿童社会性发展诸方面存在着交互作用。     

The peculiarity of the dialectical ideas of the Second Teacher,a prominent representative of the Muslim Renaissance

This paper investigates the development of dialectical concepts about the universe, being, metaphysics, scientific methods, and the knowledge of philosophers. The methods it uses are mainly theoretical and empirical methods, such as analysis and synthesis. Within the boundaries of the designated topic, it offers a systematic analysis of the historical periodization of Arab Muslim philosophy from the eighth century to the twentieth. The paper examines the activities of the prominent philosopher and mathematician Abu Nasr Muhammad ibn Muhammad al-Farabi, showing the circumstances of his borrowing certain forms, concepts, and structures from ancient Greek philosophers. The paper's main conclusion is that al-Farabi is a Second Teacher in modern philosophy, meaning the continuation in his works of the search for a scientific approach to the study of various forms of being.     

A visual auditory model based on Growing Self-Organizing Maps to analyze the taxonomic response in early childhood

In this paper we present an extension of a visual auditory neural network model previously proposed by Mayor and Plunkett (2010) in order to explain the emergence of the taxonomic response in early childhood. The original model consists of two self-organizing maps (respectively, visual and acoustic) connected with Hebbian connections. With respect to the original model, our proposal adds two major features. First, our model follows a dynamic training regime, learning categories and word-object associations that evolve through time. Second, the visual and acoustic maps are Growing self-organizing maps that grow during training, when they are no longer able to consistently represent categories. With these two new characterizing features, our model replicates the performance of the original Mayor and Plunkett (2010)’s model, acquires psychological plausibility in the training regime, and avoids the risk of catastrophic interference.     

Working with Families from the Indian Sub-Continent: An Indo-German Experience*

Whereas most Western European therapists and clients consider emotional distance and abstinence as desirable and conducive in the therapeutic process, this may not always be the case with clients from India. Cultural components such as the contrast between linear and cyclic world-views and the traditional view of the psychologist as an advisor in India present a challenge to professionals with a Western background. Some factors such as the situation of women in society and seemingly too close familiy ties can mean that a Western therapist fails to promote the changes an Indian client is desiring for his or her family. However, besides cultural awareness and caution, one of the most helpful tools in work across cultures is curiosity in its most positive sense and the readiness to be surprised by ones’ clients.I would like to thank all my Indian colleagues who supported and advised me in my work in India.     

Complex learning and information processing by pigeons: a critical analysis

Three models of conditional discrimination learning by pigeons are described: stimulus configuration learning, the multiple-rule model, and concept learning. A review of the literature reveals that true concept learning is not characteristic of the behavior of pigeons in matching-to-sample, oddity-from-sample, or symbolic matching studies. Instead, pigeons learn a set of sample-specific S^D rules. Transfer of the discrimination to novel stimuli, at least along the hue dimension, is predicted by a “coding hypothesis”, which holds that pigeons make a unique, but usually unobserved response, R₁, to each sample, and that the comparison stimulus chosen depends on which R₁ was emitted in the presence of the sample. Convincing evidence is found that pigeons do code sample hues, but there is little evidence that allows one to infer that the “coding event” must have behavioral properties. Parameters of the conditional discrimination paradigm are identified, and it is shown that by appropriate parametric manipulation, a variety of analogous tasks may be generated for both human and animal subjects. The tasks make possible the comparative study of complex learning, attention, memory, and information processing, with the added advantage that behavior processes may be compared systematically across tasks.     

A demonstration of the value of interchangeable observers

The remarkably high agreement between observers using the SRIC, the TSBC, and the CFRS makes the observers interchangeable. This agreement is a product of the intensive and extensive training and monitoring of full-time observers, the use of categories rather than continua, the low degree of interpretation required by the procedures, the use of lay language, the immediate recording after short observational periods, and the familiar and standard setting. Other important features include use of rates, emphasis on time, concern for positive behavior, and close linkages between concepts and categories so that concepts are explicitly specified. Taken together, these characteristics make these systems powerful instruments for the guidance of treatment and the prediction of outcomes. The key to their success seems to be the recording of simple actions and action sequences (the basic phenomena of psychology) as the basic data from which a variety of useful indexes can be readily formed.Preparation of this article was supported by Grant MH-30654 from the National Institute of Mental Health to S.
