The relationship between working memory, intelligence and problem-solving is explored. Wittmann and Suss [Wittmann, W.W., & Suss, H.M. (1999). Investigating the paths between working memory, intelligence, knowledge, and complex problem-solving performances via Brunswik symmetry. In P.L. Ackerman, R.D. Roberts (Ed.), "Learning and individual…

This review focuses on saccade research with adult psychiatric patients. It begins with an introduction of the various types of saccades and the tasks used to evoke them. The functional significance of the different types of eye movements is briefly discussed. Research findings regarding the saccadic performance of different adult psychiatric…

Similar manifestations of functional decline in ageing and Alzheimer's disease obscure differences in the underlying cognitive mechanisms of impairment. We sought to examine the contributions of top-down attentional and bottom-up perceptual factors to visual self-movement processing in ageing and Alzheimer's disease. We administered a novel…

Kindergarten to third grade mathematics achievement scores from a prospective study of mathematical development (n = 306) were subjected to latent growth trajectory analyses. The four corresponding classes included children with mathematical learning disability (MLD, 6% of sample), and low (LA, 50%), typically (TA, 39%) and high (HA, 5%) achieving…

Background: Trials in developing countries suggest that improving young children's diet may benefit cognitive development. Whether dietary composition influences young children's cognition in developed countries is unclear. Although many studies have examined the relation between type of milk received in infancy and subsequent cognition, there has…

A study was conducted to determine the degree of relationship between eye movement patterns and cognitive mapping as determined by the Cognitive Style Mapping Instrument (CSMI). It was hypothesized that a high correlation exists between a predominance of visual and auditory eye movement patterns and the visual and auditory cognitive mapping styles…

This investigation of cognitive effort begins with a review of cognitive principles relating to memory and graphic encoding of information. The cognitive framework described allows explanation of improved memory due to reparsing of graphic representations. It also provides the basis for optimizing graphical material design to insure best retention…

This booklet presents educational programs and activities for perceptual training of 4- to 9-year-olds and older children with learning and reading problems. The development of visual and auditory perception needs to be understood as closely related to and dependent upon other developmental areas, including motor, language, thinking, emotional,…

The relationship between students' relative ability in visual-spatial tasks as well as their verbal and numerical skills to their performance in an introductory college chemistry course was investigated. For 700 subjects, verbal and mathematics Scholastic Aptitude Test scores (SAT-V) and (SAT-M) and the following four perceptual tests were…

Technological advancements in television images have resulted in an increase of media imagery. One cause of people's fascination with the new media technology is the constant utilization of depth axis staging. The visual elements that make up the image are often placed within the Z-axis, moving rapidly toward or away from the viewer, often…

Witkin's Embedded Figures Test (EFT) was used to measure the changes with age in field dependence and problem-solving ability. Qualitative data concerning problem-solving strategies and quantitative data were collected. EFT was administered to 12 females in each of the following decades: 20s, 30s, 40s, 50s, 60s, 70s. All subjects were moderately…

A random sample and a sample of retarded readers were selected from fourth- and sixth-grade students in the Grand Prairie Independent School District. All students were tested in the areas of auditory perception, visual perception, and phonics abilities. The tests administered were: two subtests from the Woodcock Reading Mastery Test; four…

The theory that reading is a perceptual process was tested in a study involving 216 fourth, fifth, and sixth graders. The significance of the relationship between performance on a standard reading test and on an apparatus designed to test visual/motor perception was assessed. An analysis of the data revealed that there was no relationship between…

This paper discusses a longitudinal, exploratory study of developmental dimensions related to object permanence theory and explains how multidimensional scaling techniques can be used to identify developmental dimensions. Eighty infants, randomly assigned to one of four experimental groups and one of four counterbalanced orders of stimuli, were…

INTERACTION BETWEEN VISION AND HEARING WERE STUDIED IN 35 SPEECH HANDICAPPED FIRST-GRADE CHILDREN. THE ABILITY TO SHIFT ATTENTION FROM ONE SENSORY MODALITY TO ANOTHER WAS LABELED AS "PERCEPTUAL SHIFTING." A DEVICE DEVELOPED BY EXPERIMENTAL PSYCHOLOGISTS PRESENTED VARIOUS STIMULI TO EACH SUBJECT AND RECORDED THE SUBJECT'S REACTION TIME.…
