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,…

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…

Four experiments tested four month olds on visual discrimination tasks. As the time allotted to solve these problems was shortened, infants who looked at stimuli for a short amount of time performed better than other infants, indicating that performance superiority was attributable to speed of processing.

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)

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)
