Items have been studied heretofore for their value as elements of particular tests to the neglect of more fundamental research into the multiple potentiality of items. This article proposes a method of grouping items into synonymies comprising all of the items which correlate with a given key item. These synonymies can be used for interpretation of the total meaning of the key item: (1) by inspection of the constituent items and (2) by correlational study of obtained single scores of individual persons. The method is illustrated by four items with inter- and intra-correlations, and characteristics of an ideal background reservoir of items are pointed out.  相似文献

The relationship between basic research with nonhumans and applied behavior analysis is illustrated by our work on activity anorexia. When rats are fed one meal a day and allowed to run on an activity wheel, they run excessively, stop eating, and die of starvation. Convergent evidence, from several different research areas, indicates that the behavior of these animals and humans who self-starve is functionally similar. A biobehavioral theory of activity anorexia is presented that details the cultural contingencies, behavioral processes, and physiology of anorexia. Diagnostic criteria and a three-stage treatment program for activity-based anorexia are outlined. The animal model permits basic research on anorexia that for practical and ethical reasons cannot be conducted with humans. Thus, basic research can have applied importance.  相似文献

The Star Counting Test (SCT) has been developed to measure the regulatory function of attention. In a previous study it was shown that the SCT is suited for assessment of this attentional aspect with children. The present study concerns a more difficult version aimed at young adults. In the literature, the regulatory function of attention is increasingly stressed and it has been linked to working memory functioning. In order to further determine the validity of the SCT, performance was checked against two kinds of measures relating to working memory, i.e. Digit Span and Computational Span. These tasks both call for storage but differ in their claims on the processing component of working memory. Using confirmatory factor analysis substantial correlations were demonstrated with either of these measures. As expected, the correlations tended to rise with increasing demands on the processing component. Test scores were further compared with self-reported cognitive failures. No significant relation appeared to exist. The results are interpreted in terms of demands on the regulatory function of attention.  相似文献

The purpose of this article is to provide potential consultants with a broad introduction to the learning, gestalt, systems, organizational, psychoanalytic, and chaos theories of consultation. The goal of this article is to demonstrate how the consultant can map each of these theories onto the consultation environment to produce a unique perspective that each theory alone cannot provide. Each theory is described as to how it views and frames the consultation problem and how interventions are then based on these frames. Additionally, each theory is examined as to its view of process difficulties and when termination is deemed appropriate.  相似文献

Why Socioeconomic Status Affects the Health of Children   总被引:3,自引:0,他引:3  
Abstract— This article provides an overview of research on socioeconomic status (SES) and physical health in childhood. SES has a gradient relationship with children's health, such that for each incremental increase in SES, there is a comparable benefit in children's health. In this article, I discuss psychosocial mechanisms underlying this association and argue that it is important to utilize knowledge about how the relationship between SES and health changes with age to inform a developmentally plausible search for mediators of this relationship. Furthermore, SES at different points in a child's lifetime may have different effects on health. I advocate an interdisciplinary approach to searching for mediators that would allow researchers to understand how characteristics of society, the neighborhood, the family, and the individual child are involved in the processes linking SES and children's health.  相似文献

This study explores the relative importance of everyday racism, empathic concern, communalism, and religiosity as predictors of pro-social involvement (i.e., volunteerism and membership in political/social justice organizations) among a sample of African American men (N = 151). Church involvement emerged as a positive predictor of the likelihood that these men were involved in volunteer work as well as the number of hours that men dedicated to volunteer work. Communalism positively predicted the amount of time (in hours per year) that men were involved in volunteer work. Subjective religiosity and the stress of everyday racism were associated with a greater likelihood of being a member of a political–social justice organization. Implications of these findings are discussed.  相似文献

ObjectivesTo explore the relative contributions of self-esteem, body-esteem components and body mass index to disordered eating in aesthetic female athletes and non-athletic females and specifically to determine if the body-esteem components are risk factors for disordered eating.MethodsOne hundred and fifty two participants, of which 61 rhythmic gymnasts, 42 synchronized swimmers and a non-athletic group of 49 female college students completed the self-esteem scale, the body-esteem scale (satisfaction with general appearance, weight satisfaction and others' evaluations of one's body and appearance), the eating attitudes test, and the body mass index was computed.ResultsResults showed a strong heteroscedasticity for EAT-26 and therefore scores were modeled separately for the three groups. For rhythmic gymnasts, the final regression model only emphasizes the role of body-esteem attribution. For the synchronized swimmers, the final regression model combines two body-esteem dimensions (body-esteem for weight and body-esteem attribution) and their interaction. For the non-athletic group, the final regression model only emphasizes body-esteem for weight. Body mass index and low self-esteem were not predictive of disordered eating and no significant relationship was found between body-esteem for appearance and eating attitudes scores. The use of exploratory graphs such as graphs of conditioning and level plots provided more detailed information on the relationship between body-esteem dimensions and eating attitude scores.ConclusionsResults contributed to the growing literature on disordered eating suggesting that attention must be paid to body-esteem for weight and attribution in the understanding of disordered eating and their interaction. Future research should take into consideration the complexity of these results and use a larger sample of aesthetic athletes to elaborate on the current findings.  相似文献

Temperament traits may increase risk for developmental psychopathology like Attention-Deficit/Hyperactivity Disorder (ADHD) and disruptive behaviors during childhood, as well as predisposing to substance abuse during adolescence. In the current study, a cascade model of trait pathways to adolescent substance abuse was examined. Component hypotheses were that (a) maladaptive traits would increase risk for inattention/hyperactivity, (b) inattention/hyperactivity would increase risk for disruptive behaviors, and (c) disruptive behaviors would lead to adolescent substance abuse. Participants were 674 children (486 boys) from 321 families in an ongoing, longitudinal high risk study that began when children were 3 years old. Temperament traits assessed were reactive control, resiliency, and negative emotionality, using examiner ratings on the California Q-Sort. Parent, teacher, and self ratings of inattention/hyperactivity, disruptive behaviors, and substance abuse were also obtained. Low levels of childhood reactive control, but not resiliency or negative emotionality, were associated with adolescent substance abuse, mediated by disruptive behaviors. Using a cascade model, family risk for substance abuse was partially mediated by reactive control, inattention/hyperactivity, and disruptive behavior. Some, but not all, temperament traits in childhood were related to adolescent substance abuse; these effects were mediated via inattentive/hyperactive and disruptive behaviors.
