Examined the ability of 1-year olds to remember the location of nonvisible targets. Found that infants were able to associate a nonvisible target with a direct landmark and to code its distance and direction with respect to themselves or the larger framework. Difficulty of coding with indirect landmarks was associated with cognitive complexity and…

Test Battery was designed to explore the auditory and the visual perceptual processing abilities of children from five through eight. (Authors)

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)

The rationale and development of a new series of motion picture tests of perceptual abilities of young children are described, and preliminary data regarding their reliability and validity are presented. The data suggests that the film tests are promising new perceptual measurement instruments. (MS)
