Adults vary their haptic exploratory behavior reliably with variation both in the sensory input and in the task goals. Little is known about the development of these connections between perceptual goals and exploratory behaviors. A total of 36 children ages 3, 4, and 5 years and 20 adults completed a haptic intramodal match-to-sample task.…

We explored the perceptual structure of facial expressions of six basic emotions, varying systematically in intensity, in adults and children aged 7 and 14 years. Multidimensional scaling suggested that three- or four-dimensional structures were optimal for all groups. Two groups of adults demonstrated nearly identical structure, which had…

Reports four experiments that examined four-year olds' ability to coordinate orthogonal spatial dimensions. Found that performance was particularly good when two imagined lines of sight were the dimensions to be coordinated. Results support the notion that young children perform better when tasks are set in a meaningful context. (MM)

Tested in two studies 4- to 7-year-olds' face recognition by manipulating the faces' configural and featural information. Found that even with only a single 5-second exposure, most children could use configural and featural cues to make identity judgments. Repeated exposure and feedback improved others' performance. Even proficient memories were…

Investigated suppression of activation and retrieval paths to information stored in long-term memory. Subjects were 94 children in grades 1, 3, and 5. Found that the ability to intentionally inhibit the maintenance and recall of irrelevant information improves over the elementary years, and children are less able than adults to withhold production…

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)
