Performance on the Wechsler Intelligence Scale for Children-Revised was compared for reflective and impulsive children, aged 8-11. Reflective children scored higher on the attention-concentration and visual organization subtests. There were no significant differences in verbal comprehension. (Author/GDC)

Visual preference technique was found to be a method for exploring the genesis of normal and abnormal selective attention, pattern discrimination, and recognition memory. The study of infants with differing degrees of risk for mental subnormality produced substantial evidence for relationship between early visual selectivities and future…

The results showed that accuracy depended on both stimulus complexity, modality, and mental age, regardless of whether or not the Ss were retarded. The selection of haptic search styles also depended on these factors but, in addition, was influenced by the intellectual status of the children. (Author/DLS)

Evidence on the poorer spatial visualization ability in various Negro populations compared to the White populations and on the direction and magnitude of sex differences in spatial ability relative to other abilities suggests the genetic hypothesis that spatial ability is enhanced by a sex-linked recessive gene and that, since the 20-30 percent…

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 study investigated the visual discrimination abilities of children who varied in their ability to recognize words. Measures of word recognition and intelligence were obtained in 87 first-, second-, and third-grade subjects. All subjects then performed a visual discrimination task which uses artificial graphemes as stimuli. The task required…

Selected elements of reading and psychomotor characteristics among good and poor readers of divergent intellectual abilities were investigated. Four groups were selected for study: good and poor readers who were of average ability, and good and poor readers who were mentally handicapped. Approximately 160 subjects were identified for testing, and…

The concurrent and discriminant validity of La Prueba de Analisis Auditivo, a Spanish auditory perception test, and the validity of the perceptual deficit hypothesis and of hypotheses derived from verbal processing theory were evaluated in a sample of 114 second-grade Hispanic pupils receiving reading instruction in Spanish.
