In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6-7, 9-10, and 11-12 years) were tested on the Colavita task (Experiment 1) and 32 children (6-7, 9-10, and 11-12 years) were…

Over their 1st year of life, infants' "universal" perception of the sounds of language narrows to encompass only those contrasts made in their native language (J. F. Werker & R. C. Tees, 1984). This research tested 40 infants in an eyetracking paradigm and showed that this pattern also holds for infants exposed to seen language--American Sign…

This study investigated perception of audiovisual sequences in 3- and 4-month-old infants. Infants were habituated to sequences consisting of moving/sounding or looming/sounding objects and then tested for their ability to detect changes in the order of the objects, sounds, or both. Results showed that 3-month-olds perceived the order of 3-element…

Four experiments were conducted to investigate the development of visual accommodation in one- to three-month-old infants. Accommodation responses and pupil diameters were measured at various stimulus distances. Results suggest that changes in depth of focus in the first three months are largely responsible for growth in accommodation. (Author/SS)

In three experiments, three- and four-year olds were asked to map relative size from one array of objects to another, map relative size to relative proportion, and map relative size to a variety of perceptual dimensions. Children were able to make relational mappings based on size when spatial positions and concrete representations of size of…

Tests the hypothesis that age-related shifts in infants' visual preferences for stimuli (varying in complexity as defined by number of light-dark intersections) are due to changing attention value both within and between the inversely varying dimensions of size and number. (Author/ED)

The reactions of 112 10-month-old male infants to the property of curvature were examined using a habituation paradigm with lever pressing as an instrumental response. (SB)

Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern.

In an evaluation of the relation between dimensional salience and preschoolers' judgments of bigness, 3-year-old children were shown triads of rectangles and asked to select the "big" one. The biggest rectangle in each triad was neither the tallest nor the widest. (JMB)

One- and two-month-old infants were shown schematic drawings of a human face with features arranged (1) naturally, (2) symmetrically but scrambled, and (3) asymmetrically and scrambled. Two-month-olds discriminated among all arangements and preferred the natural arrangement; one-month-olds showed no discrimination or preference. (Author/DB)

Used a habituation-dishabituation procedure to test ability of 4-, 5-, and 7-month-olds to differentiate between a subjective ellipse and a nonsubjective pattern that were constructed by displacing the inducing elements of the illusory figure. Found that even 4-month-olds discriminated between the subjective ellipse and nonillusory display. This…

First, third, and fifth graders made judgments of the geographical slant of surfaces depicted in photographs while optical slant and postural orientation were manipulated. The results indicated the existence of a linear mechanism which compensates for the effect of postural inclination. (JMB)

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)
