Individuation, ego development and family negotiation of conflict were studied in 27 Norwegian families with an adolescent daughter, 16–19 years, drawn from a larger sample to represent a rectangular distribution of ego development. Individuality and Connectedness (individuation) as conceptualized and scored by Condonet al. (1984) was modified and adapted to a Norwegian material. Four factors were extracted, one related to individuality (self-assertion and separateness) and two to connectedness (clarification and acceptance). Ego development, measured by the Washington University Sentence Completion Test (Loevinger & Wessler, 1970) was related to connectedness between mother and daughter and between father and daughter, but not to individuality. Maturity of conflict negotiation was positively related to connectedness between mother and daughter and negatively to individuality between father and daughter. It was argued that for women, individuality may not be a singular goal in ego development or in individuation and that self-other differentiation of identity and interests may develop within a close relationship and not only through separation.  相似文献

A review of the domestic violence research was conducted to assess the most salient factors that predict the likelihood of a woman remaining in or leaving an abusive relationship. The research is still in its early stage and no single theory can confidently predict this tendency on the part of battered women. Research that currently appears to provide the best explanations for remaining in an abusive relationship and factors that enable women to end their abuse are summarized.  相似文献

The intelligence, academic achievement, and classroom behavior of 158 children were assessed in a sample that is being followed longitudinally. The sample included children at high risk for mental disorder by virtue of having a parent with a psychiatric diagnosis of schizophrenia or affective disorder, children at moderate risk, and children at low risk, A series of path analyses indicated that in this sample (1) classroom behavior was more likely an affect than a cause of academic achievement, and (2) the influence of parental psychopathology on classroom behavior was mediated by a child's intelligence and academic achievement. We were unable to substantiate an unmediated causal link between parental psychopathology and children's academic achievement or classroom behavior.This research was supported by National Institute of Mental Health Grant MH 24819 to Drs. E. J. Anthony and J. Worland. The authors appreciate the help of the entire Harry Edison Child Development Research Center staff, especially Janet Penniman, Steven Finn, Harriet Lander, Arlene Stiffman, Victor Hesselbrock, Darcy Gilpin, Janice Hensiek, and Crisanne Roberts. Special thanks are expressed to Myra Ferrel and Alice Woods for making arrangements with the schools. Our gratitude is expressed to the principals, counselors, and teachers of the St. Louis area schools and to the children and families who participated in this effort.  相似文献

Incorporating temporal decline in predictive validity into mental testing theory is outlined. Starting from multivariate regression of criterion on repeated measurements, an analytic extension results in a weighting function for repeated measurements, replacing the beta weights. Besides optimizing, the procedure permits an evaluation of any particular prognosis setting: In cases of exponentially declining predictive validity, prognostic range can be extended if concurrent validity is nonperfect by optimal weighting (predictive filtering) of repeated measurements. Considerable gain in prognostic range over the traditional approach can be achieved if predictive validity declines concavely downwards.This work was supported by grant Dr 58/3 from Deutsche Forschungsgemeinschaft.  相似文献

Thirty-six preschoolers were administered and retested on a 15-item Peer Preference Test designed to measure the reward value of peers for each child. Test-retest reliability was .88, and after item analyses, 12 items were maintained in the test. The revised test was then administered to 29 other preschoolers. Test-retest reliability was. 77, and item analyses indicated that each item made a significant contribution to the overall test. Concurrent validation of the test was demonstrated using both a picture sociometric and a behavioral measure. In addition, the Evers-Pasquale and Sherman (1975) study was replicated, using 10 preschool social isolates.This article is based on the doctoral dissertation of the author. Gratitude is expressed to Dr. John Gleason for his counsel and advice. The author is also indebted to the staffs of the Irwin Methodist Nursery School and the Jewish Community Center Nursery School, both in Syracuse, New York, for their kindness and cooperation during the course of this investigation.  相似文献

This study investigated the relationship between hemispheric preference and communication accuracy of facial affect. Hemispheric preference was determined by rating conjugate lateral eye movements. Forty right-handed females were classified: 10 right-movers (left hemisphere preference), 15 left-movers (right hemisphere preference), and 15 bidirectionals (no hemispheric preference). Subjects were shown emotionally loaded slides portraying happiness, fear, and disgust and their videotaped facial expressions were independently rated for accuracy. It was predicted that negative emotions involved right hemisphere activity and negative affect involved left hemisphere activity. As expected, it was found that left-movers were significantly better than right-movers at nonverbally communicating disgust and fear; hemispheric preference was unrelated to expression of happiness. The accuracy scores of the bidirectionals generally fell in between those of the left-movers and those of the right-movers. The results were discussed in reference to the differential lateralization of positive and negative emotions.This study was conducted as a senior research project by the first author under the supervision of the second author.  相似文献

Proponents of the medical models have held that mental disorder is best measured in terms of some inventory of symptoms indicative of an underlying disease. Alternatively, critics have argued that mental disorder is the result of a degraded ascribed role, a discrepancy between the person and his environment, or the degradation of identity. The issue goes beyond academic debate, with important implications for case-finding and program development in community mental health. Theodore Sarbin has developed a 58-item "Conduct Impairment Scale" to operationalize the concept of "Identity Degradation" and proposed it as a substitute for the medical model. Three dimensions are posited: status, value, and involvement. An appropriate level of reliability and clustering of scale items are reported by Sarbin. In order to subject the scale to a more rigorous test, it was administered to a random sample of 208 respondents in four neighborhoods in Grand Rapids, Michigan, as part of a larger epidemiological study. In an effort to assess the validity of the scale, factor analytic methods were employed. A principal components model with varimax rotation was performed. It was found that items purporting to tap the three theoretical dimensions explicated by Sarbin did not load in the expected pattern. Additionally, the first three extracted factors accounted for only a small proportion of the total variance. Efforts to assess the reliability of the scale were more fruitful. A corrected split-half of .82 and coefficient alpha of .86 were obtained. It was concluded that the validity of the scale was not adequately demonstrated, and its use as an alternative to the medical model open to serious reservation.  相似文献

The present investigation studied observational learning in autistic children. Fifteen autistic and 15 normal children watched an adult model engage in a set of behaviors under specific verbal instructions. After observing this situation, the children were tested to determine what they had acquired through observation. The results showed that (1) the majority of the autistic and the youngest normal children acquired only some limited features of the observational situation and (2) chronological age was related to the amount of learning through observation in the normal children but not in the autistics. The deficit that the autistic children showed in observational learning may be related to a failure to discriminate or attend to the total stimulus input presented. Their failure in observational learning can be seen to contribute in a major way to the severely impoverished behavioral repertoires of these children.  相似文献

In an attempt to determine whether the commonly described deficits associated with hyperactivity — inappropriate activity, short attention span, low frustration tolerance, and impulsivity — are unique to this population, hyperactive, behavior problem, asthmatic, and normal control children were studied. The tests most often used in research with hyperactives were administered. Hyperactives, when compared to normals, did show deficits in the aforementioned areas. However, when compared to the behavior problem and asthmatic children only the attentional deficits clearly differentiated hyperactives from the other children.This research was supported, in part, by grants from the Ontario Ministry of Health (DM-304) and the Ontario Mental Health Foundation (#652-76A).  相似文献
