This study evaluates the relationship between the social climate from different services and the personal goal-directed activities of 224 individuals with AIDS. The study's results supported the main hypothesis that recipient and participatory service involvement uniquely influence personal goal-directed activities, even after considering individuals with AIDS' physical symptoms, psychological distress, income, and recruitment site. Income and involvement with participatory services were both positively related to the amount of personal goal-directed activity. Longitudinal analyses suggest that personal initiative contributes to the subsequent amount of personal goal-directed activities a person pursues. These results suggest further examination of factors contributing to the selection of different service types and of the processes underlying the relationship between participatory services and positive outcomes for clients with AIDS.  相似文献

Canonical correlations with fallible data   总被引:1,自引:0,他引:1  
The technique of canonical correlation may be used to determine the extent to which two sets of measurements reflect the same underlying traits. However, if the two sets are not perfectly reliable, the unreliability may obscure the fact that they are essentially dependent on similar processes. If we attempt to determine sets of weights so as to maximize the correlation between linear composites after correction for attenuation in the composites, it turns out that the results may be obtained by determining the canonical correlations and canonical regression weights between the true score components of the measures making up the two sets. In addition, formulas are developed for calculating the correlations between the canonical variates and original measures, both corrected and uncorrected for attenuation. A numerical example relating the verbal to the performance subtests of the Wechsler Intelligence Scale for Children is presented.  相似文献

The aim of this article is twofold. Both Origen and Gregory of Nyssa treat of the Lord's Prayer, the former in his own treatise On Prayer , the latter in the course of five sermons on the same prayer. By means of an analysis of the methods of both writers and of the results at which they arrive I hope to illustrate their respective treatments of the same text and so to show how what began life as an eschatological prayer became in the course of three or four centuries something rather different. A major difficulty faced by both writers is how to understand the coming of the kingdom, if it is already there.
My second intention, beyond that of comparison is to assess what influence, if any, was exercised by Origen on Gregory. The answer arrived at is rather disappointing, above all for those who believe in a strong influence on Gregory of his predecessor, by way of his grandmother, Macrina. Not only are the styles of the two men quite different, but also, apart from a sort of common Platonism, their answers are often quite distinct.  相似文献

Human social, cognitive, and linguistic functioning depends on skills for rapidly processing action. Identifying distinct acts within the dynamic motion flow is one basic component of action processing; for example, skill at segmenting action is foundational to action categorization, verb learning, and comprehension of novel action sequences. Yet little is currently known about mechanisms that may subserve action segmentation. The present research documents that adults can register statistical regularities providing clues to action segmentation. This finding provides new evidence that structural knowledge gained by mechanisms such as statistical learning can play a role in action segmentation, and highlights a striking parallel between processing of action and processing in other domains, such as language.  相似文献

Performance on task switching, a paradigm commonly used to measure executive function, has been shown to improve with practice. However, no study has tested whether these benefits are specific to the tasks learned or are transferable to new situations. We report evidence of transferable improvement in a cued, randomly switching paradigm as measured by mixing cost, but we report no consistent improvement for switch cost. Improvement in mixing costs arises from a relative reduction in time to perform both switch and nonswitch trials that immediately follow switch trials, implicating the ability to recover from unexpected switches as the source of improvement. These results add to a growing number of studies demonstrating generalizable improvement with training on executive processing.  相似文献

Children's Emotional Security in the Interparental Relationship   总被引:1,自引:0,他引:1  
ABSTRACT— In response to the societal premium placed on understanding the difficulties faced by children from high-conflict homes, emotional security theory aims to understand precisely how and why interparental discord is associated with children's psychological problems. One of its main premises is that interparental discord increases children's vulnerability to mental illness by undermining their sense of safety or security in the context of the interparental relationship. In this article, we highlight the main assumptions of a new ethological formulation of emotional security theory and its predictions and findings regarding the organization, precursors, and consequences of individual differences in children's emotional insecurity. We conclude with a synopsis of the value of the new formulation for future work.  相似文献

For many, the concept of videogame addiction seems far-fetched, particularly if their concepts and definitions of addiction involve the taking of drugs. This paper overviews the small, but growing area of videogame addiction and then examines the treatment options available for those affected by excessive videogame playing. An overview of the available empirical literature appears to indicate that adverse effects are likely to affect only a relatively small subgroup of players and that frequent players are the most at-risk for developing problems. Worldwide, there are relatively few practitioners that specialise in the treatment of videogame addiction and this may be because there are so few players who are genuinely addicted to playing videogames. However, the Internet may be facilitating excessive online game playing as evidenced by the increasing number of specialist addiction treatment clinics for online videogame addiction. This paper overviews the various approaches that have been used as an intervention in treating videogame addicts, including online support groups, 12-step programmes, behavioural and cognitive-behavioural therapies, and motivational interviewing.  相似文献

Hoarding has historically been conceptualized as a symptom of Obsessive Compulsive Disorder (OCD); however, data demonstrate important differences between hoarding and OC symptoms (for discussion, see Grisham et al. Anxiety Disorders, 19, 767‑779. 2005). Hoarding has also been observed in disorders besides OCD, including specific Impulse Control Disorders (ICDs; e.g., kleptomania, trichotillomania, pathological gambling, compulsive buying). Therefore, the current study tested the hypothesis that hoarding would be as strongly related to symptoms of ICDs as it is to OCD and that these relationships would be medium to strong in magnitude. Results from an undergraduate sample showed hoarding behaviors were strongly related to symptoms of OCD, moderately related to symptoms of compulsive buying, and more modestly related to symptoms of pathological gambling, trichotillomania, and kleptomania. Finally, findings suggest indecisiveness may be a particularly important underlying feature in hoarding behaviors. These results support the consideration of hoarding outside the confines of OCD.
