This article presents a method for using Microsoft (MS) Excel for confirmatory factor analysis (CFA). CFA is often seen as
an impenetrable technique, and thus, when it is taught, there is frequently little explanation of the mechanisms or underlying
calculations. The aim of this article is to demonstrate that this is not the case; it is relatively straightforward to produce
a spreadsheet in MS Excel that can carry out simple CFA. It is possible, with few or no programming skills, to effectively
program a CFA analysis and, thus, to gain insight into the workings of the procedure. 相似文献

Recent findings are reviewed indicating that upper alpha oscillations - when analyzed with appropriate time/ frequency resolution - show a similar physiological reactivity as theta in working memory tasks. Comparable to theta, a load dependent increase in power can be observed during retention and increased evoked activity during retrieval. During retrieval attempts theta behaves like a traveling wave spreading from anterior to posterior sites. During actual retrieval, however, evoked upper alpha becomes transiently nested in theta. We suggest that theta reflects working memory functions whereas upper alpha may be important for the reactivation of long-term memory codes in short-term memory. 相似文献

Background: To introduce a person with multiple disabilities to a microswitch-aided program, one has to select a plausible response(s),
that is, a response(s) that can be performed reliably and without excessive effort by the person and can successfully activate
the microswitch(es) available (producing preferred stimuli). This paper provides an overview of the responses adopted for
microswitch activation in research studies during the last 20 years. Method: Computerized and manual searches were carried out to identify the studies published between 1986 and 2005. Forty-eight research
studies were identified. They concerned the use of (1) a single (typical) response, (2) a single (non-typical) response, (3)
multiple (typical and non-typical) responses, and (4) multiple (vocal) responses. Results and discussion: The results showed that 151 of the 190 participants involved in the studies had a positive outcome (i.e., clear increases
in their responding, which suggested that they had learned the association between responding and consequent preferred stimuli).
Failures were largely concentrated in the first group of studies. The discussion focused on (a) the importance of selecting
plausible responses for increasing the chances of success, (b) the need of non-typical responses for persons with minimal
motor behavior, (c) implications of programs with multiple responses on engagement and choice, and (d) relevance of using
vocal utterances. Some suggestions for future research concerning these points were also examined. 相似文献

Two previous studies found that life stress and parental alcoholism were not as highly related to distress for Hispanic adolescents as they were for European American adolescents (M. Barrera Jr., S. A. Li, and L. Chassin, 1993, 1995). Those findings could be interpreted as evidence of Hispanic youths' resilience, but limitations of the stress measure and the homogeneity of the Hispanic sample threatened this interpretation. The present study improved on those previous studies by using a new measure of uncontrollable stressors and a more heterogeneous Mexican American sample. Participants in this study were 175 Mexican American and 59 European American adolescents and their parents. Unlike the previous studies, results did not show that Mexican American adolescents were more resilient to parental problem drinking or life stress than were European American adolescents. Overall, life stress was related to adolescents', mothers', and fathers' reports of adolescents' psychological distress above and beyond the effects of ethnicity and socioeconomic factors. 相似文献

Two studies found positive relationships between the ability to manage emotions and the quality of social interactions, supporting the predictive and incremental validity of an ability measure of emotional intelligence, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). In a sample of 118 American college students (Study 1), higher scores on the managing emotions subscale of the MSCEIT were positively related to the quality of interactions with friends, evaluated separately by participants and two friends. In a diary study of social interaction with 103 German college students (Study 2), managing emotions scores were positively related to the perceived quality of interactions with opposite sex individuals. Scores on this subscale were also positively related to perceived success in impression management in social interactions with individuals of the opposite sex. In both studies, the main findings remained statistically significant after controlling for Big Five personality traits. 相似文献

A prototype analysis of forgiveness 总被引:3,自引:0,他引:3
Many definitions of forgiveness currently exist in the literature. The current research adds to this discussion by utilizing a prototype approach to examine lay conceptions of forgiveness. A prototype approach involves categorizing objects or events in terms of their similarity to a good example, whereas a classical approach requires that there are essential elements that must be present. In Study 1, participants listed the features of forgiveness. Study 2 obtained centrality ratings for these features. In Studies 3 and 4, central features were found to be more salient in memory than peripheral features. Study 5 showed that feature centrality influenced participants' ratings of victims involved in hypothetical transgressions. Thus, the two criteria for demonstrating prototype structure (that participants find it meaningful to judge features in terms of their centrality and that centrality affects cognition) were met. 相似文献
