Abstract: | Previous studies using simple, repeating patterns have suggested that the knowledge gained in early sequence learning is
not effector-specific in that it transfers to muscle groups other than those used during training. The current experiments
extended these findings to transfer after extensive practice with probabilistic sequences using a task on which people fail
to gain declarative knowledge of the regularity. Specifically, an alternating serial reaction time (ASRT) task was used in
which predictable and unpredictable trials alternated. Participants responded for the first five sessions using their right
hand, then switched to the left hand for the sixth session. Stimuli were spatial in the first experiment and nonspatial in
the second. Significant near-perfect transfer of pattern knowledge was seen in both experiments, suggesting that muscle-specific
information for either the fingers or the eyes cannot explain the observed learning.
