The prior entry hypothesis contends that attention accelerates sensory processing, shortening the time to perception. Typical observations supporting the hypothesis may be explained equally well by response biases, changes in decision criteria, or sensory facilitation. In a series of experiments conducted to discriminate among the potential…

According to even the most conservative estimates, at least a quarter of deaf children have additional disabilities. Most teacher preparation programs do not sufficiently prepare teacher candidates for the challenges posed by these children. This article describes a professional development effort to prepare in-service educators of the deaf to…

We report a 53-year-old patient (AWF) who has an acquired deficit of audiovisual speech integration, characterized by a perceived temporal mismatch between speech sounds and the sight of moving lips. AWF was less accurate on an auditory digit span task with vision of a speaker's face as compared to a condition in which no visual information from…

G. Senf's study of bisensory integration language tasks was modified and replicated with 52 normal and 52 learning disabled children. Results confirmed the original study except for a more consistent pattern for individual difference variables and failure to replicate the main effect of stimulus interpair presentation times.

Findings revealed significant correlations between all three measures of visual motor development as well as those measures and the Wechsler Intelligence Scale for Children-Revised Performance IQ. The VMI-Revised appeared appropriate for measuring paper/pencil fine motor aspects of visual perceptual development in children. (CL)

Two partly overlapping frequency glides can be perceived as consisting of a long pitch trajectory accompanied by a short tone in the temporal middle. It was found that the appearance of this middle tone could not be related to peripheral processes concerned with spectral splatter or combination tones that could have emerged during the overlap of…

In many theories of cognition, researchers propose that working memory and perception operate interactively. For example, in previous studies researchers have suggested that sensory inputs matching the contents of working memory will have an automatic advantage in the competition for processing resources. The authors tested this hypothesis by…

All children have their own unique ways of interacting with their environments, connecting with people around them, and learning about their world. Babies take in information from their senses and use this information to respond to people and events. Children's daily experiences facilitate integration of their senses. These early sensory…

Recent research indicates that by 4.5 months, infants use shape and size information as the basis for individuating objects but that it is not until 11.5 months that they use color information for this purpose. The present experiments investigated the extent to which infants' sensitivity to color information could be increased through select…

Neurobiological models propose an evolutionary, vertical-integrative perspective on emotion and behavior regulation, which postulates that regulatory functions are processed along three core brain systems: the brainstem, limbic, and cortical systems. To date, few developmental studies applied these models to research on prenatal and perinatal…

Failure to attain handwriting competency during the school-age years often has far-reaching negative effects on both academic success and self-esteem. This complex occupational task has many underlying component skills that may interfere with handwriting performance. Fine motor control, bilateral and visual-motor integration, motor planning,…

A group of 182 children (ages four through nine) with known or suspected sensory integrative dysfunction were assessed using tests and clinical observations to examine developmental dyspraxia. The study did not justify the existence of either a unitary function or different types of developmental dyspraxia. (Author/CH)

A description of the development of movement by infants covers prenatal influences, gravity influences, sensory aspects of motor skills, deformities and deviations in the developmental sequence, and ways to assist infants with abnormal development patterns. (CB)

Often, the sound arriving at the ears is a mixture from many different sources, but only 1 is of interest. To assist with selection, the auditory system structures the incoming input into streams, each of which ideally corresponds to a single source. Some authors have argued that this process of streaming is automatic and invariant, but recent…

For seven years, the author has been the parent of a wonderfully uniquely gifted little boy, who has taught her all about "exceptional" parenting. Her child, Adrian, is a "twice-exceptional" child who is both intellectually gifted and has special needs that negatively impact his development and learning. Initially, the contradictions of parenting…
