Whisker deflection is an effective conditioned stimulus (CS) for trace eyeblink conditioning that has been shown to induce a learning-specific expansion of whisker-related cortical barrels, suggesting that memory storage for an aspect of the trace association resides in barrel cortex. To examine the role of the barrel cortex in acquisition and…

In tactile learning, sucrose is the unconditioned stimulus and reward, which is usually applied to the antenna to elicit proboscis extension and which the bee can drink when it is subsequently applied to the extended proboscis. The conditioned stimulus is a tactile object that the bee can scan with its antennae. In this paper we describe the…

In this research on motor short-term memory it was hypothesized that subjects making free-selected movements would evidence superior reproduction accuracy over subjects making preselected movements, whose reproduction performance would be superior to subjects making constrained movements. Subjects making free-selected movements were allowed to…

Examined the effect of attention on infants' responses to briefly exposed visual stimuli. Found that the duration of stimulus exposure in the familiarization phase was positively correlated with the preference for the novel stimulus in the paired-comparison procedure, and processing of briefly presented visual stimuli differed depending on the…

Tests the hypotheses that superiority of semantic over phonetic encoding increases with age, and that the superiority of multiple-dimension encoding over single-dimension encoding emerges with age. Elementary, secondary, and graduate students judged words on various dimensions of the semantic differential in an incidental memory task. (Author/SS)

This experiment was designed to better understand the effects of individual differences, intent to learn, and stimulus familiarity on frequency judgment accuracy. Half of the participants in the study heard popular songs, and the other half listened to unfamiliar songs. Participants were subdivided into three more groups, introducing the "intent…
