Competing explanations of the beneficial effect of spacing in retardate discrimination learning were tested. Results are inconsistent with consolidation and rehearsal theories but support the prediction of the Geber, Greenfield, and House spacing model that forgetting from short-term memory facilities retardate learning.

The role of memory factors in the vowel discrimination of normal and at-risk 8-week-old infants was examined by studying the categorical versus continuous discrimination of very brief vowels in a nonnutritive sucking paradigm. Discrimination of the silent delay interval between the last familiar and the first novel stimulus was also examined.…

Results of a study of recognition memory showed that 3-year-old children were able to discriminate schematic faces, but were not able to use this knowledge unless given training in attaching labels to the stimuli to enable them to store the information for later use. (Author/JMB)

This study examined children's use of category information as a discrimination cue to avoid intrusions in recall and false alarms in recognition of items outside given categories. Forty-eight children in grades 1 and 4 were administered one of three conditions of a recognition task in which all study words were members of one of two familiar…

The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)

This is a partial report of a longitudinal investigation designed to assess the psychological effects of an experimentally conducted day care program on children during the first 30 months of life. The experimental subjects were Chinese and Caucasian children from working and middle class families who were cared for at a special group care center…
