Eye movement of nonreaders (kindergarten subjects) and readers (third-grade subjects) were measured during a visual discrimination task involving matched and unmatched pairs of four-letter pseudowords. Both quantitative and qualitative analyses support the conclusion that the development of perceptual strategies is a direct result of increasing…

The concluding article in a two-part series intended to direct the reader to detailed information concenring specific matters rela tive to the planning, preparation and successful utilization of visualized presentations.... This part deals specifically with the design and production of visual materials for presentation." (Author/LS)

Reports that form matching increased with age both in number of subjects with reliable preferences and in strength of preferences, but that at all ages form matches predominated. (Author/DR)

The effects of reinforcement contingencies on task performance of bisensory missing words were studied with two students (about nine years old): one learning disabled (LD) male with an auditory preference and one LD female with a visual preference. Reinforcement contingencies were found to control both students' performances. (Author/SEW)

After viewing pictures of simple objects varied in color and spatial location, first, third, and fifth graders were assessed for their abilities in automatic processing of spatial and color information. In general, no evidence was found to suggest that the processing strategies of younger children were less sophisticated than those of older…

The reinforcing properties of four sensory stimuli (continuous and flashing light, vibration, and sound), which were under the subject's control, were examined and the effect on stereotyped behavior of 24 severely retarded and autistic children were observed. Findings were interpreted to support the self-stimulation theory of stereotypy despite…

Subjects judged whether aerial views would be seen by an observer oriented in various ways. For practiced subjects, time to answer was an approximately linear function of number of abstract spatial dimensions on which aerial view and observer's orientation were consistent. Ability correlated with linearity of response-time. (Author/RD)
