A hierarchical progression in infants' ability to use surface features, such as color, as a basis for object individuation in the first year has been well established (Tremoulet, Leslie, & Hall, 2000; Wilcox, 1999). There is evidence, however, that infants' sensitivity to surface features can be increased through multisensory (i.e.,…

The ability to individuate objects is one of our most fundamental cognitive capacities. Recent research has revealed that when objects vary in color or luminance alone, infants fail to individuate those objects until 11.5 months. However, color and luminance frequently covary in the natural environment, thus providing a more salient and reliable…

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)

Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Experiment 1 compared 6- and 8-year-old boys in inter- and intramodal matching of fast or slow spatiotemporal patterns with long or short interpattern intervals. Experiment 2 made the same comparisons for 7- and 9-year-old boys using temporal patterns. (Author/JMB)

Study looks at pigtailed macaque in the context of visual recognition problems adapted from a standardized test developed for use with human infants. Results demonstrate that the low-risk group easily differentiated novel from previously seen targets; the high-risk group gave no evidence of recognition. (Author/RWB)

A total of 72 children, 36 each from first and sixth grades, were given a 70-item study list followed by a recognition test list of equal length. To indicate the relative dominance of features encoded at both ages, labels, pictures, and referents were recombined to form visual, semantic and acoustic distractors. (MS)
