A study tested a multiple-resources model of human information processing wherein the two cerebral hemispheres are assumed to have separate, limited-capacity pools of undifferentiated resources. The subjects were five right-handed males who had demonstrated right visual field-left hemisphere (RVF-LH) superiority for processing a centrally…

Two techniques were used to modify an impulsive conceptual tempo on a visual discrimination task. The subjects were 42 first grade white children who had previously been classified as impulsive or near-impulsive on the Matching Familiar Figures Test given to 82 children. These subjects, who had scored above the median on errors and below the…

Reviews "Levels of Cognitive Development," which presents a theory of cognitive development integrating discrimination- learning research with understanding of higher cognitive processes. Argues that strengths include its presentation of systematic research and providing continuity between past and present models. Weaknesses include…

Ten second graders with reading disabilities were presented with the visual analog of an auditory phonological training approach (intrasyllable discrimination) previously studied. Results indicated that children receiving the intervention significantly improved their phonological processing abilities. (SLD)

This study used functional magnetic resonance imaging (fMRI) to examine brain-behavior correlations in a group of 16 children (9- to 12-year-olds). Activation was measured during a semantic judgment task presented in either the visual or auditory modality that required the individual to determine whether a final word was related in meaning to one…

Research on adult memory for nonverbal representations has found a significant age-related decrement in performance. To investigate age differences in adult locational versus featural information in visual memory, 90 adult women (29 young women with a mean age of 21; 30 middle aged women with a mean age of 43; and 31 older women with a mean age of…

A study investigated the size of the perceptual span within which adults use visual information to distinguish among letters as they read. The eye movements of fifteen college students were monitored as they read passages from a cathode-ray tube. On occasional fixations, letters in specified visual regions were replaced by other letters. The…

This study utilized a recognition procedure to directly assess preschool children's ability to discriminate between programs and commercials in an actual viewing situation. Seventy-two children, equally grouped by sex and age (3, 4, and 5 years) were individually presented with three videotapes. Each tape contained a sample of a 48 ten-second…

INFANT SCRIBBLING ACTIVITY IS NOT SIMPLY PLAY. IT CONTRIBUTES TO THE DEVELOPMENT OF VISUAL ATTENTION AND PERCEPTION. YET, SCRIBBLING, UNLIKE WRITING IN THE COMMUNICATION SENSE, IS NOT MOTIVATED BY THE DESIRE TO INFORM, NOR TO SET DOWN THOUGHTS AND FEELINGS. THE EXPERIMENTAL HYPOTHESIS OF THIS STUDY WAS THAT THE MOTIVATIONS FOR SCRIBBLING ARE (1)…

PRELIMINARY ANALYSES WERE UNDERTAKEN TO DETERMINE THE POTENTIAL CONTRIBUTION OF MOTION PICTURE FILMS TO FACTOR ANALYTIC STUDIES OF HUMAN INTELLECT. OF PRIMARY CONCERN WERE THE OPERATIONS OF COGNITION AND MEMORY, FORMING TWO OF THE FIVE OPERATION COLUMNS OF GUILFORD'S "STRUCTURE OF INTELLECT." THE CORE REFERENCE FOR THE STUDY WAS DEFINED…

The performance of instructor pilots and student pilots was compared in two visual scanning tasks. In the first task both groups were shown slides of T-37 instrument displays in which errors were to be detected. Instructor pilots detected errors faster and with greater accuracy than student pilots, thus providing evidence for the validity of the…

A theory for the visual and cognitive processing, which accounts for slower naming of pictures than reading of words, is introduced. Two experiments assessed the differences distinguishing word reading and picture naming, using 58 undergraduates. The coding of the mind is neither intrinsically linguistic nor imagistic; it is abstract. (TJH)

This study found that teachers' ratings of their 8 severely mentally handicapped pupils' (ages 9-18) classroom behavior were correlated with children's performance on a discrimination learning task. The factors of attention/distractibility and responsivity to consequences correlated significantly with number of errors and number of trials to…

The case study of Nadia, an autistic child, documents the phenomenally accurate drawings she made. Nadia's precocious drawing capacity raises questions about the drawing hypothesis adhered to by F. Goodenough and D. B. Harris and Gestalt theories of perception and representation. The argument is made that Nadia drew realistically because she…

To investigate the underlying factors of visual discrimination, memory, rule abstraction, language, and serial ordering in reading success, 79 poor and 65 good deaf readers were administered a battery of tests. Poor readers were deficient in lower-order visual discrimination and memory abilities; higher-order visual discrimination skills were…
