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. 相似文献

We investigated age and gender effects on “Positive Orientation” (POS)—an individual's tendency to view life with a positive outlook—using a genetically informed design. Study subjects were 1016 twins aged 22–75 from the Italian twin registry. We assessed POS by the recently developed P‐scale. First, we used confirmatory factor analysis to investigate scale's measurement invariance by age and gender. Then, we applied biometric modelling to estimate genetic and environmental components of POS score. Overall, we found a satisfactory degree of measurement invariance by both age and gender. Results from these analyses further indicated an increasing mean level of POS across the lifespan. Additive genetic and unshared environmental factors explained respectively 58% and 42% of variance in POS score, with no significant gender differences; furthermore, the pattern of change of gene‐environment architecture of POS over time was consistent with a greater plasticity of personality at older ages. 相似文献

This study investigates the extent to which response distortion occur when implicit measures of personality traits are used in applied settings. Two groups composed of 58 security guards and 45 semiskilled workers, respectively, completed five Implicit Association Tests (IATs) for assessing the Big Five personality traits as a part of a personnel assessment program. They additionally completed a self‐report measure of the same personality dimensions. Scores on the Big Five IATs and self‐ratings of personality were obtained also by 52 volunteers who responded anonymously for research purposes. Results showed that participants under evaluative testing conditions scored significantly higher than volunteers on explicit measures of agreeableness, conscientiousness, and emotional stability. On the contrary, no significant differences were found in the Big Five IATs. Practical implications of findings and future research directions are discussed. 相似文献

Self-Characterization and Attachment Style: A Creative Method of Investigating Children's Construing
This study had the aims of evaluating the self-characterization technique as a research instrument with school-age children and investigating whether and how representations of self and others vary as a function of age, gender, and attachment style. Self-characterizations completed by 103 Italian children, 47 boys and 56 girls, aged between 7 and 11 years, were analyzed using an ad hoc coding grid. The Separation Anxiety Test was administered to evaluate children's attachment style. Age predicted the process of construing as well as specific content features of the texts, such as level of abstraction and the type of construct used. In addition, gender was related to the construing process and the expression of emotion, whereas attachment style was associated mainly with stability of self-image and representation of relationships, and in consequence, the emotional aspects of identity. 相似文献

Researchers conducting psychotherapy process research aim to understand the process by which efficacious psychotherapies achieve therapeutic benefits. A key challenge in this research is how to maximise what can be learned from naturalistic longitudinal data. We provide a selective overview of research examining the process of change in cognitive therapy of depression. While the efficacy of this treatment is widely recognised, a consensus regarding how the treatment reduces depressive symptoms and provides protection from relapse and recurrence has yet to be reached. We review the current state of the research addressing the process of change in cognitive therapy, highlighting how specific methodological features can be used to better understand the process by which this treatment achieves its effects. We highlight the importance of two key challenges to making causal inferences from a process–outcome relation: (a) establishing the temporal precedence of predictors to outcome variables, and (b) evaluating whether any relations identified could be spurious. We argue that methodologically rigorous studies tend to support key claims of the model underlying cognitive therapy of depression. We conclude by considering future directions. For example, we highlight the importance of efforts to understand patient characteristics that may moderate process–outcome relations and could ultimately prove useful in tailoring treatment to best suit individual patients. 相似文献
