Accounts of statistical learning, both implicit and explicit, often invoke predictive processes as central to learning, yet practically all experiments employ non-predictive measures during training. We argue that the common theoretical assumption of anticipation and prediction needs clearer, more direct evidence for it during learning. We offer a novel(More)
UNLABELLED Sensorimotor adaptation has traditionally been viewed as a purely error-based process. There is, however, growing appreciation for the idea that performance changes in these tasks can arise from the interplay of error-based adaptation with other learning processes. The challenge is to specify constraints on these different processes, elucidating(More)

A septum is not unusual within the first dorsal compartment of the wrist. The right and left forearms of 50 cadavers were dissected. A septum was identified 34% of the time. The septum separated the abductor pollicis longus tendon from the extensor pollicis brevis tendon. If the septum was present on one side, it was usually present on the other side. The(More)
Sensorimotor adaptation is thought to be driven by an error signal based on the difference between the actual and predicted outcome of a motor command. Experiments that study this process often confound variables such as extrinsic reward and task goals with the error that adaptation seeks to minimize. Therefore changes in behavior during these tasks cannot(More)
Sensorimotor adaptation occurs when there is a discrepancy between the expected and actual sensory consequences of a movement. This learning can be precisely measured, but its source has been hard to pin down because standard adaptation tasks introduce two potential learning signals: task performance errors and sensory prediction errors. Here we employed a(More)
