Studied 2 1/2- to 6-year-old children's judgments of age category and relative age of stimulus faces, using a paired-comparison task. Faces showed variations in craniofacial profile shape, frontal face feature vertical placement, and facial wrinkling. (Author/NH)

Examines discrimination of geometric shapes by three-month-old infants who were presented with geometric stimuli moving laterally at two different velocities. Finds that subjects discriminate between geometric forms at velocities that, according to previous findings, might interfere with shape discrimination. Discusses the possible interactive…

The purpose of present experiments with subjects approximately three, five, and seven years of age was to provide additional evidence for the obviousness of the generative transmission principle and to provide initial evidence for the secondary principles of absence and facility. Empirical support was found for each of these selection principles,…

In the first of two tasks, 5- and 11-year-olds recalled the array location of social photographs of an unfamiliar adult expressing anger, disgust, fear, joy, and shame. In the second task, subjects were tested for their incidental recall of those features which were not previously isolated. Results indicated a mouth-eyes-nose hierarchy for…

Examined whether a holistic magnitude relation governs children's object comparisons. Objects varying on two dimensions of magnitude, size, and saturation were classified by three-, four-, and five-year-olds. Results indicated that younger children were sensitive to global magnitude as well as to overall similarity. (Author/BE)

Older adults are significantly slower than young adults in the naming response in the Stroop Color Word Interference Test. Hypotheses attempting to explain this age-related difference in a perceptual-cognitive task have included orthogenic principle, response-competition, and cautiousness. This study examines whether there are any significant…

Reviews Greenough, Black, and Wallace's (1987) conceptual framework for understanding the effects of early experience and sensitive periods on development, and illustrates the applicability of their model with recent data on the consequences for animals and human infants of the acquistion of self-produced locomotion. (BN)

Describes two experiments that assessed young children's understanding of the characteristic uncertainty in the physical nature of random phenomena as well as the unpredictability of outcomes. (HOD)

Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern. (HOD)

Standard or enhanced Blissymbols, designed to represent familiar actions, attributes, and objects, were shown to 20 3 year olds, who guessed their meaning. The number of their guesses that referred to the enhancements was twice as great as the number that referred to the standard Blissymbol base. (Author/JDD)

The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age. (Author/BN)

A series of three experiments was conducted to assess the comprehension of four types of cross-modal (synesthetic) similarities in children and adults. Both perceptual and verbal (metaphoric) modes were tested. (PCB)

Tests the distinction between inferring new categories on the basis of property information (predicted to be difficult) and inferring new properties on the basis of category information (predicted to be easier) among 57 preschool children. (HOD)

Investigates whether elementary school children can successfully execute a mental rotation on Marmor's state-comparison task without knowledge of logical sequence relations, whereas such knowledge is required to construct or evaluate external representations of the successive states in a rotation movement. (HOD)

Investigates the perceptual basis of metaphor by asking 5-, 7-, and 10-year-old children and adults to pair and discuss films of natural objects, both stationary and moving. Concludes that motion information makes metaphoric similarity relatively easy to perceive and influences the form of descriptive metaphors. (Author/CB)
