Effects of Physical and Observational Practice on Intermanual Transfer.

Some studies have shown that different coordinate systems in the coding of movement sequences develop during observational and physical practice. According to Newell's (Newell, 1986) constraintsled approach, such contradictions could possibly depend on task characteristics. Accordingly, in the present study, two experiments were designed using a five-segment sequence timing task, in which the instructions on how to perform the sequence were different.
