Neural and behavioral measures of human auditory peak shift effects
Preliminary Results: ERP results show the P2 and P3 components appear to most closely resemble the peak shift in the brain. Currently, results for alpha, beta, theta, and gamma activity is being processed.
The peak shift effect is a widely observed phenomenon in which discrimination learning causes generalization gradients for learned responses to peak at a novel stimulus rather than a trained one. Associative learning theories posit that the peak shift arises from reweighting connections between stimulus representations and decision/response outputs. Non-associative representational plasticity perspectives explain the peak shift as resulting from changes in stimulus representations themselves. In this latter view, the peak shift results from a distortion of perceptual memory. However, methods for examining the peak shift so far have relied heavily on analysis of gradients of learned responding, making it difficult to assess if stimulus representations are actually changing.
Our lab is currently working on understanding what is going on in the brain during the peak shift, as well as having participants use a sound pad instrument to reproduce the sound they learned. Shifts of the sounds features on the sound pad may indicate that our memory representation for the sound is actually shifting over time.
