This study compared children with either attention deficit hyperactivity disorder (ADHD) (n=24), reading disability (RD) (n=33), both (n=9), or controls. Children with ADHD were characterized by difficulty with a visual search task whereas children with RD had difficulty with an auditory processing task. Specifically, children with ADHD…

Visual analysis is examined as the dominant analytical method for single-case time series, in a study with 37 postgraduate research students which varied serial dependence, amount of random variability, and effect size. False alarm rates were high, but miss rates were low, indicating that visual analysts are not conservative judges, and serial…

The study with 34 gifted fifth-grade students found that a concrete sequential approach to developing visual literacy was more effective than an abstract visualization approach. Subjects either received guided visualization or direct instruction on such art concepts as shape, form, line, color, perspective, variety, and unity. (DB)

Delineates how the transition from one element to another facilitates the identification of individual form and function. Explains the process of bridging separate forms and functions to give meaning to what is seen. (KEH)

Describes a modified alphabet for beginning readers based on psychologies of reading and visual perception. The Graphophonic Alphabet (GP) is explained, motivations for modifying the alphabet are discussed, and possibilities for teaching phonics and second languages as well as reading with the GP and microcomputers are considered. (16 references)…

In tennis as well as in other racket/paddle sports, simply watching the ball does not guarantee success in hitting the ball to the desired location. Teachers and coaches should teach players to integrate available visual, spatial, and kinesthetic information. Several drills for good ball contact are outlined. (IAH)

The neuronal model shown to code sound-source azimuth in the barn owl by H. Wagner et al. in 1987 is used as the basis for a speculative brain-based human model, which can establish contrastive phonetic categories to solve the problem of perception "non-invariance." (SLD)

Several experiments were undertaken with a total of 111 undergraduates. Subjects attempted to imagine how three-dimensional novel wire objects would appear from viewpoints other than that of the subject. Subjects were unable to perform this task without making use of strategies that circumvent the process of visualization. (TJH)

Investigated relationship between critical flicker fusion (CFF) thresholds and five personality characteristics (alienation; social nonconformity; discomfort, expression, and defensiveness) under three auditory stimulus conditions (quiet, noise, meaningful verbal stimuli). Results from 60 college students revealed that auditory stimulation and…

A study of the reliability of teacher's interpretations of graphed performance data on students with moderate to profound mental retardation revealed that teacher judgments are consistent and accurate for continuous improvement in performance, but less consistent for variable performance. (MSE)

Findings are presented from a study designed to analyze qualitative differences in perceptual skills, measured in an educational context, between and among experienced, nominally experienced, and inexperienced teachers. Results suggest the groups differed in their ability to perceive and interpret classroom information. (IAH)

Forty-six full-term and 54 high-risk preterm infants were tested at six, seven, and/or eight months of age (corrected age for preterms) on assessments of visual recognition memory and tactual-visual cross-modal transfer. Scores significantly predicted Stanford-Binet IQ scores. Stability coefficients attained the highest degree of predictive…

Talkers vary widely in the ease or difficulty with which they can be speechread. Examined are variables contributing to visual intelligibility, comparisons with auditory intelligibility, the range of talker differences, characteristics accounting for these differences (facial cues, extrafacial gestures, rate, and rhythm), and implications for…

Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

In experiments involving 178 and 190 military recruits, spatial, quantitative, and verbal inspection time (IT) and visual search (VS) tasks and an intelligence test were administered. Results indicate that IT performance has a component related to intelligence tests and an independent component related to processing speed tests such as VS. (SLD)
