Evidence is given to indicate that Lawley's formulas for the standard errors of maximum likelihood loading estimates do not produce exact asymptotic results. A small modification is derived which appears to eliminate this difficulty.The authors are indebted to Walter Kristof and Thomas Stroud for their helpful reviews of an earlier version of this paper and particularly to D. N. Lawley for his review, comments, and encouragement. 相似文献

The relative efficacy of the major techniques typically used in behavioral treatment programs for weight reduction was investigated using obese adult volunteers. Study 1 compared the effects of self-monitoring, self-control procedures, monetary rewards, aversive imagery and relaxation training. These procedures resulted in significantly greater weight reduction than either a no treatment group or subjects who graphed and recorded daily weight. Self-monitoring of daily caloric intake was as effective as the other methods, both singly and combined, over a 4 week treatment period. Study 2 compared the long-term effects of self-monitoring vs the full complement of behavioral techniques used in Study 1. The full behavior management program was significantly more effective, both during the treatment period and at 3 and 12 week follow-ups, although self-monitoring again produced substantial weight loss. 相似文献

This article reports a second-order factor analysis of the 13 interpretable first-order factors of Adkins and Lyerly based on 66 variables for 200 Army men. The approach to simple structure for 6 second-order factors was unusually good. Loadings of the original 66 variables on the second-order factors were also obtained. Five of the factors are tentatively interpreted as Precision in Formation and Use of Verbal Concepts, General Verbal Fluency, Visualizing Spatial Constancy During Movement, Speed in Analysis, and Flexibility in Analysis. 相似文献

The relations of abilities, as measured by Thurstone'sTests for Primary Mental Abilities, to activity preferences, as measured by Kuder'sPreference Record, are investigated for a population of 512 university freshmen. Ability profiles for contrasted groups on each preference scale reveal relatively slight overlapping between the two sets of measures, although the apparent trends are reasonable. The Pearson inter-correlation coefficients of all pairs of measures involved were determined. Implications of the findings in relation to theory and to educational and vocational guidance are indicated. 相似文献

Spouse abuse remains an important social problem. Recent research has begun to explore resiliency in a variety of areas: Why, despite harsh life circumstances, do some people survive and later thrive after experiencing trauma? What are the processes associated with a successful departure from abuse? The authors worked with a local shelter to identify three groups of women: (a) those currently at the shelter; (b) those who had been away from an abusive relationship for at least one year; and (c) those who were identified by shelter staff as having demonstrated a resilient response to battering, and compared experiences and recommendations between groups and discuss clinical and service implications. 相似文献

A total of 48 educable mentally retarded (EMR) and emotionally handicapped (EH) children ( \(\overline {CA} \) =137.7 months) were pretested on Coopersmith's Self-Esteem Inventory (SEI), Nowicki-Strickland's Locus of Control Scale for Children (LCSC), and 3 behavioral measures: (1) risk-taking, (2) a chance/skill task, and (3) delay of gratification. One group of 12 children from each population was then exposed to either a self-confident or a control model. After exposure, Ss were given an opportunity to perform successfully on an ambiguous task and answer questions about their success, and were readministered the SEI, LCSC, and 3 behavioral choices. Correlational analyses of pretreatment data revealed significant relationships between defensiveness and LCSC, SEI, and delay of gratification and a near-significant relationship between LCSC and SEI. EMR and EH Ss were both lower on self-esteem than the general population, while EMR Ss were more defensive, more external, and less likely to delay gratification than EH Ss. Both treated groups matched more of the behavioral choices than the control groups, while only treated EH Ss were more likely to attribute their success to internal causes. It was concluded that EMR and EH children differ in self-concept development and that future attempts to modify self-concept should include greater modeling exposure as well as increased opportunity for performance with its resultant feedback. 相似文献

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior frontal cortex and decreased in the right caudate nucleus and superior temporal cortex bilaterally. The unaffected siblings also showed reduced grey matter in the caudate nucleus relative to controls. In an auditory covert naming task, the SLI group showed reduced activation in the left inferior frontal cortex, right putamen, and in the superior temporal cortex bilaterally. Despite spatially coincident structural and functional abnormalities in frontal and temporal areas, the relationships between structure and function in these regions were different. These findings suggest multiple structural and functional abnormalities in SLI that are differently associated with receptive and expressive language processing. 相似文献
