Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

Measures of prenatal exposure in 123 infants to polychlorinated biphenyls (PCBs), cord serum PCB level, and maternal report of contaminated fish consumption predicted less preference for a novel stimulus on Fagan's test of visual recognition memory (VRM) at 7 months. Preference for novelty decreased in a dose-dependent fashion and postnatal…

Concludes that there is a marked dimensional preference shown in most children by kindergarten, that there are relationships between dimensional dominance and letter matching, and that children program from color dominance to form dominance and then to mixed responding. (Author/RB)

Study explores the preschool child's ability to operate on a cognitive level by testing his capacity to compare a concrete stimulus with some abstract concept. (Author/CB)

Study further examined the effects of forced-choice trials on dimensional preferences. (Author)

Results indicate that for children in this study's age range orientation is a less salient discriminative cue than either size or color. (Author/MB)

Results indicate that children's preferences were relatively stable over time. (Authors/MB)

Four-year-old boys and girls initially named and matched by form more often than by color. Also, agreements involving form names and matches occurred more often than agreements involving color names and matches. (Authors)

Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

Results showed that both groups had a preferred dimension for size over pattern. When size and patterns were combined, the Down's syndrome Ss were confused by the two dimensions, showing preference for one or the other. (Author/DLS)

Two experiments investigated why perceptual pretraining facilitates children's performance on concept problems involving a nonpreferred relevant dimension and preferred irrelevant dimensions. (JMB)

This research tested the hypothesis that young children's bias to generalize names for solid objects by shape is the product of statistical regularities among nouns in the early productive vocabulary. Fifteen- to 20-month-olds given intensive naming experiences with typical noun categories developed a precocious shape bias and showed accelerated…

The developmental change from global toward dimensional classifications, usually observed in vision, was investigated in haptics with stimuli varying according to their size and roughness. Results indicated that, although more overall similarity classifications were observed in children than in adults, this kind of classification was never…

From birth, infants prefer to look at faces that engage them in direct eye contact. In adults, direct gaze is known to modulate the processing of faces, including the recognition of individuals. In the present study, we investigate whether direction of gaze has any effect on face recognition in four-month-old infants. Four-month infants were shown…
