The presence of a functional relationship between the ingestion of artificial food colors and an increase in the frequency and/or duration of selected behaviors that are representative of the hyperactive behavior syndrome was experimentally investigated. Two eight-year-old females, who had been on the Feingold K-P diet for a minimum of 11 months, were the subjects studied. The experimental design was a variation of the BAB design, with double-blind conditions. This design allowed an experimental analysis of the placebo phases as well as challenge phases. Data were obtained by trained observers on Out of Seat, On Task, and Physically Aggressive behaviors, as they occurred in the subjects' regular class setting. Results indicated (a) the existence of a functional relationship between the ingestion of artificial food colors and an increase in both the duration and frequency of hyperactive children. 相似文献

This research reports findings in a 10-year study of an apraxic adult, who was one of five subjects described by Shankweiler and Harris, (Cortex, ,2 277–292, 1966). Confusion matrices and feature analysis were used to compare 1965 and 1975 performances. Results indicate that over the 10-year period, errors of place, manner, and omission were markedly reduced. Voicing errors, however, while reduced in total number, still constituted a significant percentage of the patient's residual errors. Implications of these findings are discussed. 相似文献

A multipurpose laboratory system incorporating a voice interactive terminal and graphic display system is described. The facility is designed to investigate some aspects of human performance on concurrent verbal and tracking tasks. The results of a pilot study showing decrements in dual-task performance are reported. 相似文献

This study was designed to determine the relationship between the amount of time children spend watching television and their knowledge of adult sex-role stereotypes. Males and females in grades 1, 3, 5, and 7 who were classified as heavy television viewers (25 or more hours per week) or light viewers (10 or less hours per week) both at the time of the study and 15 months previously were administered the Sex Stereotype Measure, an instrument designed to determine children's awareness of stereotyped sex-role perceptions held by adults. Heavy viewers were found to have more stereotyped perceptions than light viewers. A significant interaction effect indicated that among low viewers the perception of male stereotypes steadily declines with increasing age; among heavy viewers, stereotypic responses to male items are maintained with increasing age. No comparable interaction effect was obtained for perception of female stereotypes. The role of interaction with live models in breaking down stereotypic perceptions of males is discussed.A modified version of this paper was presented at the meeting of the Society for Research in Child Development, Denver, April 1975. 相似文献

The impact of consultation services on teachers' preferences for consultation versus referral approaches and upon teachers' perceptions of severity for common acting out, withdrawal, and academic types of student problems were investigated. The subjects were 96 teachers whose public and parochial schools were matched and randomly assigned to treatment and control groups. Following a 14-week period during which advanced school psychology graduate students served as consultants in the treatment schools, the Pupil Problem Behavior Inventory (PPBI) was administered to all teachers. The results of a repeated measures MANOVA analysis indicated that the teachers in the treatment group rated the acting out and academic problems on the PPBI as significantly less severe than did teachers in the control group. The subjects in both the treatment and control groups indicated a significant preference for consultation rather than referral services for all types of student problems presented in the PPBI. There was a moderate, positive correlation between perceived problem severity and teacher preference for referral rather than consultation services. The study's results were interpreted as supportive of the consultation model. 相似文献

In two interview studies subjects were asked what memory aids they used and how often. In particular, the reported frequencies of use of external aids such as shopping lists and memos were compared with those of internal aids that have been investigated by psychologists, such as the method of loci. Subjects in the first study were 15 male and 15 female university students, and in the second, a group of 30 adult women, most of whom were housewives. In both studies the aids reported to be used most were external ones. However, it is pointed out that the most commonly used methods of remembering must be internal, although these are not usually considered to be aids. Some difficulties that arise in the assessment of memory in interview and questionnaire studies are discussed. 相似文献

This study addressed the problem of response class as it relates to coercive child behavior. Guttman scale analyses were used to determine if there were regular, unidimensional progressions across eight coercive response categories; that children who performed high probability coercive behaviors would also tend to perform all of the lower probability coercive behaviors. Rank-order correlations were done to determine if there was consistency in the response class across settings. Two samples of boys were observed in two school settings, classroom and playground. One sample was a derivation sample of 26 boys, the second a replication sample of 27 boys. Reproducibility coefficients for the derivation sample were .92 for the classroom Guttman scale analysis and .93 for the playground analysis. For the crossvalidation sample the reproducibility coefficients were .94 in both settings. Rankorder correlations across settings and done in terms of the number of subjects performing each of the coercive responses were .971 (df=6,p<.001) for the derivation sample and .996 df=6,p<.001) for the crossvalidation sample. It was concluded that the eight coercive responses observed appeared to constitute a response class, i.e., the ordering of the responses was transitive across subjects, and that the coercive response hierarchy was stable across school settings for groups of children.I wish to extend thanks to Gerald Patterson et al., of the Oregon Social Learning Center, for their space, time, and encouragement. Special thanks to Mark Weinrott for his excellent editorial comments. 相似文献
