This study assessed the effect of different novelty pairings and reward sequences on the exploratory behavior in successive discrimination learning problems of 60 preschool children from a Head Start program. (BRT)

An infant control habituation-recovery procedure was used to study 3-month-old infants' discrimination of sad, happy, and surprise facial expressions. (Author/JMB)

Exploring the ability of subjects to make accurate discriminations by active touch, two studies involving 20 sighted adults investigated sensitivity of the fingertip in perceiving length, using Braille cells as stimuli. Results indicated differential sensitivity of the fingertip to one parameter of active touch: cell height discrimination. (JW)

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…

Performance by 11 multiply handicapped children (3-7 years old) on discrimination tasks was used to predict performance on four common classroom tasks in auditory, sign, and visual modes. Ninety-two percent of the predictions made were accurate, indicating that the discrimination assessment was successful in determining each child's preferred…

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.

Subjects used more extra-dimensional shift solutions in the presence of novel cues than in the presence of familiar cues, except at the highest training level. (MH)

Series of experiments indicates that young infants are more sensitive to the spatial orientation of forms than was previously thought. This report is based on a dissertation submitted to the University of Strathclyde, August, 1969, in partial fulfillment of the requirements for the degree of MSc. (MH)

Reports three experiments conducted to investigate factors controlling performance of nonreinforced verbal imitation. (WY)

The amount of reinforcement received during initial learning activities has a direct effect on the ability to transfer training. (CK)
