From an ethnically diverse sample of 2,744 school children, 221 attention deficit hyperactivity disorder (ADHD) [123 (4.5%) predominantly inattentive (IA), 47 (1.7%) predominantly hyperactive/impulsive (HI), and 51 (1.9%) combined type (C)] were identified using teacher ratings on a Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) symptom checklist. Subjects were compared to 221 controls on teacher ratings of behavioral, academic, and social functioning. The results revealed relatively independent areas of impairment for each diagnostic group. The IA children were impaired in all areas, but were rated as displaying more appropriate behavior and fewer externalizing problems than HI or C children. The HI group displayed externalizing and social problems, but was rated as no different than controls in learning or internalizing problems. The C group demonstrated severe and pervasive difficulties across domains. These findings support the validity of the DSM-IV ADHD subtypes; all ADHD groups demonstrated impairment relative to controls, but show different patterns of behavioral characteristics. 相似文献

Both normal and antisocial children were extensively observed in their natural home environments. A factor analysis of the baseline data was conducted that differed from the typical factor study in two respects. Equal numbers of deviant and nondeviant behaviors were included in the analysis, and the unit of analysis was the rate-per-minute occurrence of actual child behavior. The factor structure was interpretable, and scaling of the dimensions-I, Verbal Emotionality, II, Physical Dependency, HI, Social Involvement, IV, Hostile: Controlling, and V, Hostile: Impulsive-separated groups of normal, socially aggressive, hyperactive-aggressive, and stealing children. Reported differences between aggressive and stealing children on rates of total aversive behavior were found to be due to differences in the verbal behaviors loading on the first factor.The data reported in this paper were collected with support from a grant from the National Institute of Mental Health, Section on Crime and Delinquency, Grant No. MH 15985 to Oregon Social Learning Center. The authors wish to thank Gerald R. Patterson for granting access to the data files and for very patient continuing support and advice. 相似文献

Jung's theory of psychological types provided the conceptual framework for a study of personality characteristics implicated in marital relationships. Partners in 20 couples completed the Myers-Briggs Type Indicator and a series of open-ended questions describing their marital relationships. As predicted, (a) type similarity was more characteristic than type dissimilarity, particularly on sensation-intuition and thinking-feeling preferences, (b) sensation-intuition preferences were reflected in perceptions of qualities valued in self and spouse, (c) thinking-feeling preferences were significantly related to reported satisfaction in marriage, and (d) intuitives were more open to changes in the relationship than were sensing types. Marital problems were highly diverse, and were not related in any clear way to type patterns in individuals or dyads. 相似文献

The purpose of the investigation was to replicate and extend a study by Jensen and Munro which found reaction time (RT) and movement time (MT) parameters to correlate negatively and moderately with Raven matrices performance. A sample of 20 ninth-grade girls was used. Relationships between RT and MT and Raven scores were found to be negative and moderate to high, thus replicating the Jensen and Munro study. In addition, moderate to strong negative correlations were found between RT and MT parameters and reading comprehension and performance on the California Test of Basic Skills. Weaker relationships were found for mathematics and English grades although the direction was consistently negative. 相似文献

This study addressed the degree to which adults' emotional states influence their perception of emotional states in children and their motivation to change such states. Happiness, sadness, anger, or a neutral state was induced in adults, who then viewed slides of 4-year-old children who were actually experiencing various emotional states. Adults' own emotional states had little impact on their accurate recognition of children's emotions or on their motives for social action to change such emotions. However, adults' states did influence the intensity they assigned to children's emotions, with happy adults tending to rate some emotions as more intense for black children (sadness) and for girls (anger and neutrality). The base rates with which adults used different emotion labels also influenced judgments, increasing it for the recognition of happiness and reducing it for anger. The results are discussed in terms of the factors that influence whether or not emotional states affect judgment processes and the role of emotion labels in the effective recognition of ongoing emotional states. Also addressed is the consequence of adults' recognition of emotion in children for the effective socialization of emotion. 相似文献

A procedure is described for restraining the pigeon while recording movement of the nictitating membrane. The preparation provides a means of studying classical conditioning that combines the rich sensory capacities of the pigeon with the control achieved in nictitating membrane conditioning of the rabbit. 相似文献
