ABSTRACT
Sensorimotor adaptation has traditionally been attributed to the operation of an error-based learning system that operates in an implicit and automatic manner. However, recent work has shown that multiple processes, including high-level strategies contribute to learning in such simple tasks. In the first part of the talk, I will discuss how processes associated with action selection and motor execution interact during sensorimotor adaptation. In the second part, I will describe a new method that allows us to eliminate the contribution of strategic processes, thus providing an uncontaminated analysis of implicit sensorimotor adaptation. The results from this work reveal limitations with current models of sensorimotor adaptation and suggest important constraints on how the cerebellum keeps the sensorimotor system well calibrated.
BIO
Rich Ivry is a professor of psychology and neuroscience at the University of California, Berkeley.
He received his Ph.D. in Cognitive Psychology from the University of Oregon in 1986. He has been at Berkeley since 1991, directing the Cognition and Action lab. His research program explores various aspects of human performance with a focus on how people select, plan, and produce skilled movements.
The lab uses many of the methods of cognitive neuroscience including behavioral studies in healthy and neurologically impaired populations, TMS, fMRI, EEG, ECoG, and computational modeling.
