A sequential matching task was used to compare how the difficulty of shape discrimination influences the achievement of object constancy for depth rotations across haptic and visual object recognition. Stimuli were nameable, 3-dimensional plastic models of familiar objects (e.g., bed, chair) and morphs midway between these endpoint shapes (e.g., a…

Emphasizes the role that motor development may play in determining developmental sequences in other domains, such as haptic or tactile perception and depth perception. Maintains that there is a high degree of fit between the developmental sequence in which certain perceptual sensitivities unfold and the ages at which the corresponding motor…

A circuit approach and station techniques are used to depict perceptual motor games for handicapped and nonhandicapped children. Twenty activities are described in terms of objectives, materials, and procedures, and their focus on visual tracking, visual discrimination and copying of forms, spatial body perception, fine motor coordination, tactile…
