Explaining neurocognitive aging: is one factor enough?

As an introduction to the special issue on neurocognitive factors underlying age effects, we discuss a number of recent developments in the literature on aging. The classic distinction between generalized and process-specific cognitive changes with old age has reappeared in the distinctions between the frontal lobe hypothesis and more differentiated views of neurocognitive aging. We argue that neurological decay in the frontal cortex has important implications for cognitive control, but that the frontal lobe hypothesis does not capture the plethora of changes that characterize aging and incorrectly suggests a unitary effect.     

Test Anxiety: A Cross-Cultural Perspective

The present paper examines test anxiety from a cross-cultural perspective with specific reference to the Indian and American cultures. The construct of test anxiety has been examined in many cultures all over the world. In this review, the importance of understanding and incorporating contextual factors in cross-cultural research is emphasized. Moreover, some of the methodological issues related to investigating culture-behavior relationship are discussed. Specifically, the derived-etic approach for conducting cross-cultural research is espoused. Then, research findings from western, cross-cultural, and Indian studies on test anxiety are reviewed. Consistent with the individualistic orientation of the western society, much of the research in the western world has adopted a de-contextualized approach. Inasmuch as many of the cross-cultural and Indian studies on test anxiety have their roots in western research, they have ignored the cultural context as well. To address this void, contextual variables relevant to test anxiety in the Indian setting are examined and hypotheses regarding the nature of test anxiety in Indian children are proposed. Finally, a research agenda is presented to examine these hypotheses using a derived-etic approach.     

Parental Alcoholism and Co-Occurring Antisocial Behavior: Prospective Relationships to Externalizing Behavior Problems in their Young Sons

The hypothesis that parental alcoholism and co-occurring antisocial behavior would be indirectly linked to child externalizing behavior problems through child lack of control, current levels of parent depression, family conflict, and parent–child conflict was tested using manifest variable regression analysis. Participants were a community sample of 125 families with an alcoholic father and 83 ecologically matched but nonsubstance abusing families involved in the first 2 waves of an ongoing longitudinal study (with 3 years between each wave). All families had a biological son who was 3–5 years old at study onset. Results revealed that child lack of control mediated the relation between paternal alcoholism and the son's subsequent externalizing behavior problems. Family conflict was a significant mediator of maternal and paternal lifetime antisocial behavior effects and father–son conflict mediated paternal lifetime antisocial behavior effects. Study implications are discussed within the context of parental socialization of antisocial behavior.     

Comprehension of reversible relative clauses in specifically language impaired and normally developing Greek children

This paper aims to investigate the syntactic comprehension of reversible relative clauses in a group of eight Greek children with specific language impairment (SLI) and two control groups of normally developing children matched on chronological and language age, respectively. An experiment using an acting out procedure was undertaken. Group analysis revealed that SLI children's performance is qualitatively different than that of both control groups. Interpreting the data, processes involved in syntactic comprehension are taken into consideration. It is claimed that processing demands impede SLI children's performance due to a deficit in their competence grammar.     

Trust, Dependency, and Control in the Contemporary Organization

Trust is an essential element in productive and effective intraorganizational communication and interaction. The present study examined several consequences of trust in terms of influence strategies used and the frequency with which people interact with each other. The study also examined the extent to which the technology of work affects management's dependency on their employees. It was found that distrust of subordinates by managers (n = 275) was associated with the use of strong tactics of influence, little dependency on employees, and the use of personal-related characteristics to explain distrust. It was also found that distrust of managers by subordinates (n = 267) was associated with the use of strong methods of influence, less interaction, less attempts to influence, and the use of personal-related characteristics to explain lack of trust. These findings have clear implications for understanding the relation among worker trust, dependency, and social influence. The data suggest that both employees and employers could benefit from considering the importance of a trusting relationship in the workplace.     

Identifiability of nonlinear logistic test models

The linear logistic test model (LLTM) specifies the item parameters as a weighted sum of basic parameters. The LLTM is a special case of a more general nonlinear logistic test model (NLTM) where the weights are partially unknown. This paper is about the identifiability of the NLTM. Sufficient and necessary conditions for global identifiability are presented for a NLTM where the weights are linear functions, while conditions for local identifiability are shown to require a model with less restrictions. It is also discussed how these conditions are checked using an algorithm due to Bekker, Merckens, and Wansbeek (1994). Several illustrations are given.This article was written while the first author was a post doctoral fellow at the university of Twente.

大学生考期应激的特征及原因分析

旨在研究考期应激的表现特征,并探讨其产生的原因和影响因素。以问卷方法测量了261名在校大学生。结果发现47．89％的被试有不同程度的考期应激症状,其中以睡眠症状为最典型的特征。考期应激症状很少受性别、专业、年级、是否担任班干部和个性倾向等因素的影响,且具有较明显的时间特征。诱发考期应激的主要因素有：考生“对考试目的的认知”、“对考试内容的认知”及“生恬和学习环境”等。结论为,考期应激是一种大学生中较普遍且具有多重原因的应激现象。

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

Theorizing Gerontology: The Case of Old Age, Professional Power, and Social Policy in the United Kingdom

This article examines the interrelationship between old age, professional power, and social policy. In particular, dominant theoretical models in social gerontology are reviewed and an alternative framework for understanding social gerontological issues—Foucauldian gerontology—is advanced. Foucauldian narratives are employed to delineate the historical relationship between professional social work and recent social policy for older people in the United Kingdom. In addition, a Foucauldian framework employed to examine identity formation, professional practices, and policy narratives enriches and widens the disciplinary subject matter of theorizing aging studies. The structure of this article is in three parts: review of theories of aging with an introduction of Foucault's potential contribution to gerontological analysis, the historical overview of the instigation of professional intervention in modernity and the changing roles and responsibilities in relation to older people utilizing Foucault's (1977) genealogical method, and the exploration and application of Foucault's key notion of governmentality (1977; Rose & Miller, 1992) in the analysis of social policy for older people.
