Four experiments investigated newborns' ability to discriminate, recognize, and learn visual information embedded in the schematic face-like patterns preferred at birth. Results indicated that newborns discriminated face-like stimuli relying on their internal features and recognized a perceptual invariance between face-like configurations in…

Two five-year-old children with profound hearing impairments were involved in a conditional discrimination task. They were taught to relate manual signs, pictures, and printed words in a nominal matching-to-sample task in such a way that equivalent stimuli resulted. Results showed that the establishment of equivalence relations can promote…

Two experiments examined whether 40 infants would reenact what an adult did or intended to do: (1) infants observed an adult unsuccessfully attempt to complete 4 target acts; and (2) children observed a mechanical device tracing the adults' actions. Infants could infer adults' intentions and imitate target acts, suggesting that children can…

Results of numerous human imaging studies and nonhuman neurophysiological studies on "reward" highlight a role for frontal, striatal, and thalamic regions in operant learning. By integrating operant and functional neuroimaging methodologies, the present investigation examined brain activation to two types of discriminative stimuli correlated with…

Experiment I was designed to demonstrate that young children fail to abstract the positive cue as the relevant stimulus event in a restricted concept-learning task. Sixteen kindergarten and 16 fourth grade subjects were trained to criterion on a Kendler-type task, whereupon each subject was presented a pair of new instances which contrasted only…

Second and fifth graders were presented with a discrimination learning task in which each of four displays were to be paired with a response button. For one group two of the displays shared a common feature and were paired with the other response button. This common feature condition required a subject to learn only two associations if he…

Investigated effects of dimensional dominance of stimuli and subject's ages in initial and shift learning of discrimination tasks. (DP)
