To examine the ontogeny of emotional face processing, event-related potentials (ERPs) were recorded from adults and 7-month-old infants while viewing pictures of fearful, happy, and neutral faces. Face-sensitive ERPs at occipital-temporal scalp regions differentiated between fearful and neutral/happy faces in both adults (N170 was larger for fear)…

Infants five- and seven-months-old were sequentially shown three stimulus arrays of visual elements, only one of which was capable of producing subjective contours. An infant habituation control procedure was used to test infants' abilities to discriminate the arrays. (Author/RH)

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)

The preference for color or form as bases for similarity judgments among preschoolers (ages 2-5) and its relationship to the differentiation of form and color concepts as indexed by discrimination, identification, and labeling were investigated. (SB)

This study was designed to determine whether modifying the task characteristics of the Stage 6 sensorimotor means-end problem (by introducing additional visual cues) aided task solution in children. Subjects were 80 children, ages 20-33 months. (CS)

The ability of 40 children four and five years of age to discriminate reflections and rotations of visual stimuli was examined in a kinetic imagery task. Results revealed that prediction accuracy was associated with the existence of orientation markers on the stimuli, as well as age, sex, type of discrimination, and several interactions among the…

Three experiments examined how flexibly two- to four-year-old children use the words "big" and "little" in normative, perceptual, and functional contexts. Results showed that children switched easily from a normative context but made errors when asked to switch to a normative context. (MDM)

Children, ages 9 to 13 years, made judgments of proportion with a variety of graphical elements in 2 experiments. A characteristic pattern of over- and underestimation was observed; this pattern was also present, but previously unnoticed, in judgments made by adults. (MDM)

Wariness did not set in gradually over a period of time but, on the contrary, was found in its fully developed form at 9 months, having been completely absent at 8 months. (Authors/MB)

This study investigated the hypothesis that there is a developmental trend toward greater flexibility of strategies in visual selection. Subjects were 48 second and sixth graders. (Author/SDH)

Examined age-related changes in visual selective attention--ability to resist interference--in children 5 to 12 years old and adults. The interference effect on stimulus evaluation did not discriminate between age groups; however, the interference effect on correct response activation showed a pronounced age-related reduction, suggesting a…

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Preschool children were asked to choose the figure most resembling a real man from three figures drawn according to formulas used by children to depict humans. Results suggest development of drawing systems influences children's conceptions about objects or events. (Author/DB)
