Reports three experiments in infant visual perception which studied the processes underlying infants' shifts of fixation from one object to another. (JMB)

If various color names are printed in various color inks, an observer has great difficulty in rapidly naming the ink colors (Stroop Color Word Test) unless the color names and the ink colors are mutually reinforcing, or the color names are unknown to the observer. The latter suggests a partial measure of second-language fluency, the feasibility of…

Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)

Sixty children, prereaders and readers aged 4-6 years, matched color, shape, and letter features in pairs of cartoons. Older children and those able to read performed better, confirming the hypothesis that the development of some visual skills is a by-product of learning to read. (Author/SJL)

The results offered little support for the hypothesis that teaching severely retarded learners to label stimuli would reduce the likelihood of stimulus overselectivity. (Author)

Stimuli varying in form, color, and size were presented on a demonstration trials procedure to 25 severely retarded adults and to 25 nonretarded children of equivalent MA. (Author/SB)

There was some evidence to support the suggestion that certain types of mentally handicapped children attend to singe cues rather than to total configuration. There was also evidence of perceptual distortion resulting in reversal and attraction to "good form." (Author)

Several propositions deduced from the discrepancy hypothesis were tested with four-month-old infants using random shapes in a habituation/discrepancy paradigm. (JMB)

This study tested whether the first level in processing orientation information results in perceiving whether a shape is upright or nonupright. Theory states that nonupright orientations are not distinguished from each other. As predicted, three- and four-year-olds discriminated upright from nonupright pictures more readily than they discriminated…

Reports three experiments which investigated the discrimination of simple visual arrangements by three-month-old infants. An operant high-amplitude sucking technique was used in a stimulus familiarization-novelty paradigm. (JMB)
