Event-related potentials (ERPs) were utilized in an investigation of 21 six-month-olds' attention to and processing of global and local properties of hierarchical patterns. Overall, infants demonstrated an advantage for processing the overall configuration (i.e., global properties) of local features of hierarchical patterns; however,…

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)…

Previous research suggests that model competence does not emerge until relatively late in infancy (20-26 months). Development was systematically analyzed within 3 key areas--count noun learning, dual representation, and categorization--hypothesized to support the emergence of model competence in the second year. In an object-handling preferential…

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

Differences in response of four- to seven-month-old infants to tachistoscopically presented photographs of two human faces suggest infants were able to remember a frequently presented face from trial to trial and discriminate it from a discrepant, infrequently presented face. Findings suggest event-related brain potential (ERP) responses could…

Five experiments tested four-month-old infants' ability to recognize degraded visual targets as a function of individual differences in fixation duration. Found that short-looking infants were able to recognize degraded forms in both vertex (top or highest point)-absent and vertex-present conditions, but the vertex-absent discrimination was more…

Existing data indicate that newborns are able to recognize individual faces, but little is known about what perceptual cues drive this ability. The current study showed that either the inner or outer features of the face can act as sufficient cues for newborns' face recognition (Experiment 1), but the outer part of the face enjoys an advantage…

Children often perseverate, repeating prior behaviors when inappropriate. This work tested the roles of verbal labels and stimulus novelty in such perseveration. Three-year-old children sorted cards by one rule and were then instructed to switch to a second rule. In a basic condition, cards had familiar shapes and colors and both rules were stated…

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)

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)
