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…

The percent and characteristics of children who produced invalid profiles on two different continuous performance tests (CPTs) tasks were examined. Sixty-one children referred for attention deficit hyperactivity disorder (ADHD) assessment and 24 non-clinical control children (all children ages 5-16) were given the Test of Variables of Attention…

To investigate sensory dominance in early development, a series of studies examined six-month-old infants' processing of multisensory stimulus compounds. Findings indicated that infants discriminated changes in the temporal characteristics of the auditory component but not in the visual component. This and other findings suggested that auditory…

Involving 10-month-old infants, a series of studies examined responses to temporally modulated compound auditory-visual stimuli. Findings indicated that, although the auditory modality can dominate the visual modality at 10 months of age, the visual modality can process temporal information when the temporal relationship of the information in the…

The paper addresses the need to define terms used in vision training before successful programs can be formulated. Critical behaviors in three categories (visual attending, visual examining, and visually guided motor) are considered as are program alternatives focusing on visual environment management, visual skills training, and visually…

Abilities of individuals (n=42), either with or without mental retardation, to search for and detect changes to naturalistic scenes were investigated. Individuals with mental retardation required more time to detect changes, especially changes of marginal interest. Eye-tracking analysis of six participants suggested that individuals with mental…

This study compared visual attention in 18 prelingually deaf children (half with cochlear implants and half with hearing aids) and 10 normal hearing children. Unlike previous studies, children in all three groups performed similarly on a continuous-performance visual attention task and on a letter cancellation task. Only age and nonverbal…

Determines whether early hemispheric differences exist in tactual processing by testing infants and preschoolers on six cross-modal tasks. Results are the first to demonstrate a left-hand superiority for information processing in children as young as two years. (Author/AS)

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…

This study investigated potential effects of auditory and other communicative experience on development of visual attention in 80 infants (tested at 9, 12, and 18 months), half deaf and half with deaf mothers. Results indicate that early visual attention is associated with and potentially influenced by a complex interaction of maturation,…
