Learning to divide the labor: an account of deficits in light and heavy verb production

Theories of sentence production that involve a convergence of activation from conceptual‐semantic and syntactic‐sequential units inspired a connectionist model that was trained to produce simple sentences. The model used a learning algorithm that resulted in a sharing of responsibility (or “division of labor”) between syntactic and semantic inputs for lexical activation according to their predictive power. Semantically rich, or “heavy”, verbs in the model came to rely on semantic cues more than on syntactic cues, whereas semantically impoverished, or “light”, verbs relied more on syntactic cues. When the syntactic and semantic inputs were lesioned, the model exhibited patterns of production characteristic of agrammatic and anomic aphasic patients, respectively. Anomic models tended to lose the ability to retrieve heavy verbs, whereas agrammatic models were more impaired in retrieving light verbs. These results obtained in both sentence production and single‐word naming simulations. Moreover, simulated agrammatic lexical retrieval was more impaired overall in sentences than in single‐word tasks, in agreement with the literature. The results provide a demonstration of the division‐of‐labor principle, as well as general support for the claim that connectionist learning principles can contribute to the understanding of non‐transparent neuropsychological dissociations.     

Self‐concept: a tourism application

Although well accepted by consumer behaviourists in general, self‐concept has received relatively little attention from tourism researchers. This is despite the potential it would appear to offer in terms of enabling an enhanced understanding of how tourists feel and what they seek from the tourism experience. The application of a model of self‐concept in this study suggests self‐concept may provide an alternative segmentation base, giving insights into how people perceive themselves in the tourist role and their consequent behaviour.

Untangling the associations that narcissistic admiration and narcissistic rivalry have with agency,communion, and romantic commitment

The Narcissistic Admiration and Rivalry Concept (NARC; Back et al., 2013) proposes two strategies for maintaining a grandiose self-image. These dimensions are positively correlated, but often have divergent associations with outcomes. When used simultaneously to predict outcome variables, suppression effects often occur. We examine suppression effects for narcissistic admiration and narcissistic rivalry in four samples (total N = 2106), examining their bivariate distribution and transforming the predictors to emphasize common and unique sources of variance. High composite NARC (high narcissistic admiration and narcissistic rivalry) was associated with more positive self-perceptions of agency, slightly more negative self-perceptions of communality, and less romantic commitment. Domination of the narcissistic admiration pathway relative to the narcissistic rivalry pathway predicted more positive self-perceptions.     

语言和文化对空间认知的影响 ——汉族和纳西族大学生空间词相似性分类的比较研究

以纳西族和汉族大学生为被试,对Yi-Fu Tuan归纳的17对空间词进行了相似性分类,并用多维标度法和分层聚类法进行了分析。结果表明,汉族大学生的空间认知围绕着4个主题：⑴三维方位;⑵边界;⑶空间饱和程度;⑷视觉距离。汉族大学生空间词的概念结构有两个维度：⑴方位/状态;⑵以观察者为参照/以物为参照。纳西族大学生的空间认知围绕着5个主题：⑴垂直方位;⑵水平方位;⑶边界;⑷空间饱和度;⑸视觉距离。纳西族大学生空间词的概念结构也有两个维度：⑴水平/垂直;⑵状态/方位。汉族大学生和纳西族大学生空间认知的差异主要表现在“水平/垂直”维度上,这与汉族和纳西族的语言和文化差异相一致。整个研究表明,语言和文化对空间认知主题和空间概念结构有着重要的影响     

A longitudinal study of Q‐sort attachment security and self‐processes at age 5

Attachment theory predicts that a sense of self emerges from early interactive relationships with significant others. In the current study, concurrent and predictive relations of child–mother Q‐sort attachment security to self‐concept and self‐esteem in 5‐year‐old children is examined. Concurrent attachment security scores are positively related to a puppet interview measure of self‐esteem, and children who are able to admit imperfections in themselves have higher attachment security scores at age 5. Attachment security at age 2 is not positively related to self‐processes, however, and security at either age does not predict overall self‐concept as measured by the Harter Scales. The results suggest that a secure attachment relationship is important for children to feel comfortable in presenting a realistic perspective of themselves.     

What is personality? Two myths and a definition

This article addresses the longstanding problem that the field of personality psychology remains in need of a consensus formulation of its core subject matter, that of the nature of “personality” itself. Part 1 of the article presents some reminders about the traditional pre-empirical status of concepts in science. Part 2 introduces and calls into question two widely accepted but nonetheless questionable propositions about the nature of personality: (a) that the term refers to an underlying causal entity within a person, and (b) that the study of personality is the study of the whole person. Part 3 presents a definition of “personality”, discussion elaborating and clarifying this definition, and an explication of the ways in which it differs from previous definitions. Part 4 discusses some benefits that accrue both to having a consensus definition in general, and to acceptance of the present definition in particular.     

Collective school-type identity: predicting students' motivation beyond academic self-concept

In Germany, according to their prior achievement students are tracked into different types of secondary school that provide profoundly different options for their future educational careers. In this paper we suggest that as a result, school tracks clearly differ in their social status or reputation. This should translate into different collective school‐type identities for their students, irrespective of the students’ personal academic self‐concepts. We examine the extent to which collective school‐type identity systematically varies as a function of the school track students are enrolled in, and the extent to which students’ collective school‐type identity makes a unique contribution beyond academic self‐concept and school track in predicting scholastic motivation. In two cross‐sectional studies a measure of collective school‐type identity is established and applied to explain motivational differences between two school tracks in Berlin. In Study 1 (N = 39 students) the content of the collective school‐type identity is explored by means of an open format questionnaire. Based on these findings a structured instrument (semantic differential) to measure collective school‐type identity is developed. In Study 2 (N = 1278 students) the assumed structure with four subscales (Stereotype Achievement, Stereotype Motivation, Stereotype Social, and Compensation) is proved with confirmatory factor analysis. This measure is used to compare the collective school‐type identity across school tracks and predict motivational outcomes. Results show large differences in collective school‐type identity between students of different school tracks. Furthermore, these differences can explain motivational differences between school tracks. Collective school‐type identity has incremental predictive power for scholastic motivation, over and above the effects of academic self‐concept and school track.     

The reliability and construct validity of scores on the Japanese version of an academic self‐concept scale for a sample of college students1

Abstract: This study investigated the internal consistency, reliability, and construct validity of scores on the Japanese version of the Dimensions of Self‐Concept (DOSC) academic self‐concept scale for a sample of 177 students at a small Japanese private college. Confirmatory factor analyses showed promising support for the construct validity of scores on the six factor subscales (Level of Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, Identification versus Alienation, and Stress), representing the six hypothesized constructs of academic self‐concept. Internal consistency reliability of scores on the six subscales ranged from 0.82 to 0.87.
