Five considerations of a comprehensive configuration to carry out computer-based instructional management are described. Included are data communications networks, loading/distribution of data processing operations and Instructional Management System functions, response time, computer software, and flexibility. The need for such a configuration is…

The problem posed by this study was to determine a method of presenting information that would maximize learning, by taking into account the learner's conceptual tempo, one aspect of his cognitive style. Specifically, this study investigated the possible interaction effects of the learner's impulsive-reflective disposition with the rehearsal part…

This study extends previous research done on the impulsivity-reflection dimension whereby it was determined that children who are impulsive tend to report the first response that occurs to them, while reflective children delay before answering (considering the alternative solutions to problems with high response uncertainty); and that…

Four moderately mentally retarded students, aged 8-13, were taught to read food words found in grocery stores, using constant time delay or system of least prompts procedures. Both strategies produced criterion-level performance in training and other settings, but the constant time delay procedure was more efficient. (Author/JDD)

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…

Describes a mispronunciation detection task, in which listeners' sensitivity to deviations in speech is measured by their pressing a button upon hearing a mispronounced word in lists or sentences. Notes that reaction times and miss rates indicate the effects of position of a misplaced phoneme in a word, the size of the phonemic deviation, lexical…

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)

Two studies of adults between the ages of 18 and 87 were conducted to determine the relations among age, motor speed, perceptual speed and 3 measures of cognitive performance: study time, decision time, and decision accuracy. Results indicated that increased age was associated with lower accuracy as well as with longer study and decision time.…

Describes the development of a courier service in Oregon for document delivery between libraries to support coordinated collection development activities. Organization of the service by individual libraries without dependence on the Library Services and Construction Act is discussed, and costs and response time are considered. (two references)…

This study examined the relationships among perceived levels of intoxication, blood alcohol levels, and impairment of selected psychomotor skills used in driving. Results reinforced previous findings which correlated perceptions of intoxication and other measures. These findings suggest that alcohol consumption tables, which calculate one's…

Background: Accumulating evidence supports methylphenidate-induced enhancement of neuropsychological functioning in attention deficit hyperactivity disorder (ADHD). The present study was designed to investigate the acute effects of the psychostimulant drug, methylphenidate (MPH), on neuropsychological performance in stimulant naive boys with ADHD.…

In this study, the authors improved the understanding of the cognitive processes underlying the reflective-impulsive cognitive style (RI), which was initially measured by J. Kagan, B. L. Rosman, D. Day, J. Albert, and W. Phillips (1964) on the Matching Familiar Figures Test (MFFT). The authors determined the relationships between the RI style and…

Boys diagnosed with ADHD by specialist pediatricians and stabilized on medication were randomly assigned to a 20-session yoga group (n = 11) or a control group (cooperative activities; n = 8). Boys were assessed pre- and post-intervention on the Conners' Parent and Teacher Rating Scales-Revised: Long (CPRS-R:L & CTRS-R:L; Conners, 1997), the…

A follow-up study was conducted, using a sample of 10 teachers from two of five school districts that participated in an original project on wait time and classroom interaction. A workshop was conducted focusing on the elements of classroom discussions. In this workshop, transcripts containing short wait times were contrasted with ones with longer…

A study examined variables that affect the acquisition of automaticity of verbal skills. Among the variables examined were practice, novelty or familiarity of a word or word category, the speed and efficiency with which persons acquire automaticity, reaction time, and number of tasks performed concurrently. Subjects, 30 sixth and seventh grade…
