Constructs typically used to understand commitment between individuals were used to elucidate individual differences in goal commitment. In Study 1, 299 college students completed assessments of goal satisfaction, investments, alternatives and commitment regarding an academic goal. Structural equation modeling demonstrated confirmatory evidence for satisfaction’s, investments’, and alternatives’ collective impact on people’s goal commitment. In Study 2, the model components were manipulated by having 236 college students considered the goal to learn a new language and read information suggesting they were high or low in satisfaction, investments, and alternatives. Results demonstrated all three factors had a causal impact on people’s level of goal commitment. Both studies found an individual’s level of goal commitment was strongest when satisfaction and investments were high and the impact of alternatives was low. 相似文献

Despite theoretical assertions derived from life history theory, research on the relationship between the general factor of personality and general intelligence has shown that there is little overlap between the two higher-order constructs. It is argued that the association between these general factors is largely attenuated by measurement error in assessing the general factor of personality. A substantial association between the general factors at multiple points in time was found when the general factor of personality was derived from rater Q-sorts. The results have important implications for the study of individual differences. 相似文献

Although externally as well as internally-guided eye movements allow us to flexibly explore the visual environment, their differential neural mechanisms remain elusive. A better understanding of these neural mechanisms will help us to understand the control of action and to elucidate the nature of cognitive deficits in certain psychiatric populations (e.g. schizophrenia) that show increased latencies in volitional but not visually-guided saccades. Both the superior precentral sulcus (sPCS) and the intraparietal sulcus (IPS) are implicated in the control of eye movements. However, it remains unknown what differential contributions the two areas make to the programming of visually-guided and internally-guided saccades. In this study we tested the hypotheses that sPCS and IPS distinctly encode internally-guided saccades and visually-guided saccades. We scanned subjects with fMRI while they generated visually-guided and internally-guided delayed saccades. We used multi-voxel pattern analysis to test whether patterns of cue related, preparatory and saccade related activation could be used to predict the direction of the planned eye movement. Results indicate that patterns in the human sPCS predicted internally-guided saccades but not visually-guided saccades in all trial periods and patterns in the IPS predicted internally-guided saccades and visually-guided saccades equally well. The results support the hypothesis that the human sPCS and IPS make distinct contributions to the control of volitional eye movements. 相似文献

Abstract The present study compared two different methods of assessing alcohol and caffeine use in a community sample of adults over a one-year period. Daily reporting of beer/wine intake was more stable over time and showed higher correspondence with Quantity-frequency measures than daily reporting of hard liquor use. Coffee and tea use showed high temporal stability and good alternate form reliability, though a tendency to underreport typical use of coffee use was observed. The psychometric properties of substance use measures appear to vary with type of beverage consumed and report format. 相似文献

It is well established that fundamental aspects of cognition such as memory and speed of processing tend to decline with age; however, there is substantial between-individual variability in levels of cognitive performance in older adulthood and in rates of change in cognitive abilities over time. Recent years have seen an increasing number of studies concerned with examining personality characteristics as possible predictors of some of this variability in cognitive aging. The purpose of this article is to review the literature, and identify patterns of findings regarding the relationships between personality (focusing on the Big-5) and cognitive ability across nonclinical populations of older adults. Possible mechanisms underlying associations of personality characteristics with cognition are reviewed, and assessed in the context of the current literature. Some relatively consistent relationships are identified, including positive associations between openness and cognitive ability, and associations of conscientiousness with slower rates of cognitive decline. However, the relationships between several personality traits and cognitive abilities in older adults remain unclear. We suggest some approaches to research design and analysis that may help increase our understanding of how personality differences may contribute to cognitive aging. 相似文献

The Association for Assessment in Counseling's Committee on Assessment and Training in Addictions Counseling conducted a survey of Master Addictions Counselors (MACs) certified by the National Board for Certified Counselors. The intent of the survey was to identify which standardized assessment instruments were most frequently used by MACs and perceived to be most important in their substance abuse practices. This article describes survey results and provides training and practice recommendations. 相似文献

Judgments of average magnitude: Analyses in terms of the functional measurement and two-stage models
Subjects made magnitude estimates of the average loudness of pairs of 1,000-Hz tones varying in sound pressure. A test of fit of an averaging model employing an analysis of variance suggested that the judgments were internally consistent. However, estimates of the parameters of a two-stage model based on the assumption that power transformations were imposed in both input and output implied a nonlinear output function, inconsistent with the averaging model. Additional analyses employing a nonmetric scaling solution also suggested that output was nonlinear, indicating that this implication was not an artifact of the strong assumptions of the two-stage model. Large differences were found among the output functions of individual subjects, and it was suggested that these may have inflated the error term in the analysis of variance, reducing its power to detect violations of the additive model. Similar analyses were performed on data from judgments of average grayness collected by Weiss (1972). 相似文献
