Compensatory plasticity in the deaf brain: effects on perception of music.

When one sense is unavailable, sensory responsibilities shift and processing of the remaining modalities becomes enhanced to compensate for missing information. This shift, referred to as compensatory plasticity, results in a unique sensory experience for individuals who are deaf, including the manner in which music is perceived. This paper evaluates the neural, behavioural and cognitive evidence for compensatory plasticity following auditory deprivation and considers how this manifests in a unique experience of music that emphasizes visual and vibrotactile modalities.

Vision health care providers' attitudes and experiences with preschool vision screening in Ontario.

Purpose: The validity of preschool vision screening has been questioned in the light of the World Health Organization's criteria for determining the validity of screening programs. However, recommendations toward preschool screening have been made by a number of organizations. Given the contrasting views of screening, the purpose of this study was to examine visual health care provider experiences and attitudes toward preschool screening.

Apparent motion processing in strabismic observers with varying levels of stereo vision.

Deficits of motion processing have been reported in individuals with infantile strabismus. Here we examined motion perception in early and late onset strabismic individuals with varying levels of stereo acuity using the Fine Grain Motion Illusion (FGMI). The FGMI is an illusion of motion, where under some conditions, observers report exaggerated motion.
