Abstract:How come we are able to adapt to changes in our environment so well when performing tasks with both our hands? Twenty-four right-handed participants practiced 2 bimanual discrete sequence production (DSP) sequences with both hands placed adjacently. In 2 test phases (little vs. extensive practice), the right forearm was moved 90° outward. Performance was slowed (p < .01) and the hands did not differ in the amount of slowing, nor was this effect different after extensive practice (Fs < 1). It suggests that we use hand-based frames of reference that readjust by slowing all components of a sequence. Chunks containing keypresses by both hands and an equal slowing for both hands suggest that these frames may also overlap.
