Missing the mark: Effects of time and causal attributions on goal revision in response to goal-performance discrepancies.

In an attempt to extend past goal setting research, the present study examined the influence of goal-performance discrepancies (GPDs), causal attributions, and temporal factors on the process of dynamic self-regulation. Goal revision processes were examined longitudinally in a sample of 100 varsity-level college track and field athletes over the course of an 8-week competitive season. The results indicate that an individual's GPD significantly predicted the amount of goal revision engaged in by the athletes, such that participants were more likely to lower their competition (proximal) and season (distal) goals when they failed to reach these goals and their respective GPDs were large. However, as hypothesized, this relationship was moderated by stability attributions and the temporal location of the individual with respect to the time period allotted for goal attainment. Implications for future research in the area of goal setting and dynamic self-regulation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Practice Variability and Transfer of Training: The Role of Self-Efficacy Generality.

Practice variability has been shown to enhance transfer of training. The purpose of the present study was to examine the role of self-efficacy generality as a motivational mechanism in explaining the relationship between practice variability and transfer. Undergraduate students (N = 82) were randomly assigned to 1 of 2 training conditions (constant or variable) for a computer decision-making task. Measures of self-efficacy (intensity and generality) and transfer (near and far) were assessed. The results provided support for some of the hypothesized relationships. Specifically, practice variability led to increased self-efficacy generality. Both self-efficacy intensity and generality influenced far transfer performance, although only self-efficacy generality served as a mediator between practice variability and far transfer.

The over-claiming technique: Measuring self-enhancement independent of ability.

Over-claiming is a concrete operalization of self-enhancement based on respondents' ratings of their knowledge of various persons, events, products, and so on. Because 20% of the items are nonexistent, responses can be analyzed with signal detection formulas to index both response bias (over-claiming) and accuracy (knowledge). Study 1 demonstrated convergence of over-claiming with alternative measures of self-enhancement but independence from cognitive ability. In Studies 2-3, the validity of the over-claiming index held even when respondents were (a) warned about the foils or (b) asked to fake good. Study 3 also showed the utility of the over-claiming index for diagnosing faking. In Study 4, the over-claiming technique was applied to the debate over the adaptive value of positive illusions.

论适应与发展的心理健康标准

心理健康标准一般有三种依据:医学标准、社会标准、统计学标准。一个完整的心理健康标准的制定,应该既考察适应状况,又能考察发展状况。从教育的社会价值及个人价值,特别是我国特有的教育文化背景来看,更应给发展标准以更多的关注。
