Full Description:: Sensorimotor adaptation (i.e., the capacity to adapt movements to unexpected perturbations of sensory feedback) is crucial for our survival. Retention of this learning is evident in savings, or faster relearning after returning behaviour to the naive state. Evidence shows that savings occurs because we recognize previously encountered errors, however, as perturbations evoke both sensory prediction errors (discrepancies between predicted and actual sensory outcomes of movements), as well as reward prediction errors (unexpected failures to attain a reward), it is unknown how these distinct errors contribute to savings. In this talk, I describe experiments which dissect the role of reward prediction errors in sensorimotor adaptation.

Dr Li-Ann Leow is a UQ Postdoctoral Research Fellow at the Centre for Sensorimotor Performance, HMNS UQ.
