Cognitive deficits in reading disability and attention deficit disorder   总被引:12,自引:0,他引:12  
This paper presents data from three studies (a cross-sectional study of school-referred children, a test-retest study of subtypes of reading disabilities, and a study of a large, random sample of first graders) that focus on specifying the cognitive deficits associated with reading difficulties and separating them from those associated with attentional deficits. The cognitive deficits associated with difficulty in reading were consistent across samples, developmental levels, definitions, and subtypes of reading disabilities. With IQ, age, and sex controlled for, poor readers were significantly impaired on measures of naming and phonological awareness. The effects of attentional deficits were more variable and complex but were clearly separate from the reading disability effects.  相似文献

Forty-five abusive parents (40 mothers, 5 fathers) in treatment at a large, urban medical center's child abuse program were compared on 22 parent, child, and treatment variables posited to bear on reabuse. While no one variable by itself was strongly associated with reabuse, the data indicated that interactions involving several variables (e.g., income source, marital status, and the abuser's personal abuse history) significantly differentiated between reabusers and nonreabusers. Implications of the findings for research and clinical intervention are discussed.  相似文献

School‐wide positive behavior support (SWPBS) is a systemic approach for implementing a proactive schoolwide discipline and for improving students’ academic and behavioral outcomes by targeting the school’s organizational and social culture. With a multilevel approach, the present study evaluates the relative effectiveness of SWPBS on teachers’ perceptions of the student behavior (N = 3,295) across schools, teachers, and children using a multilevel approach. We assessed teacher perception of student problem behavior five times during a 3‐year implementation of SWPBS in 23 Dutch schools. Multilevel analyses not only revealed a small increase in perceived prosocial behavior and a small decrease in problems with peers, but also different effects across children, teachers, and schools. Effects were stronger for girls and for students with higher severity of perceived problems at baseline. At teachers’ level, higher mean baseline severity of perceived problems was associated with the reduced impact of SWPBS on perceived emotional problems and problems with peers. At the school level, effects were stronger for regular schools as compared with special needs schools.  相似文献

We investigated the effects of gestational age at birth on behavioral and electrophysiological measures of 135 medically healthy infants, studied at 42 weeks postconception, and stratified into 3 groups--early-born preterms, 26-32 weeks (n = 55); middle-group preterms, 33-37 weeks (n = 43); and fullterms, 38-41 weeks (n = 37). Subjects were studied behaviorally with the Assessment of Preterm Infants' Behavior (APIB) and electrophysiologically with brain electrical activity mapping (BEAM). Fullterms showed significantly better behavioral function than both preterm groups. Less difference was found between the preterm groups. EEG spectral and photic evoked response were of significantly less amplitude for the preterms than the fullterms. Path analysis showed gestational age effects on behavioral (3 of 6) and electrophysiological (13 of 17) variables due to postnatal complications. We conclude that some differences attributable to gestational age at birth are explained by the cumulative effect of minor but unavoidable complications associated with premature birth. We speculate that remaining effects may result from developmentally inappropriate sensorimotor stimulation consequent to the premature experience of an extrauterine environment.  相似文献

This article examines the traditional assumption that higher education evaluation systems follow a similar global format. Comparative study examines institutional evaluation and assessment processes in two nation‐states that are geographically and economically remote but which, historically, share a common civic perspective. The main research question of the study is: What are the similarities and differences in the social functions of evaluation and assessment between these two countries, the models of evaluation of which originate from the same “homogeneous model of institutional evaluation”? The study demonstrates that Finnish and Argentine models of evaluation are nationally and contextually bound by general ideas rather than being applications of a global model.  相似文献
