چکیده
The authors tested specificity and the guidance hypothesis by examining the effects of continuous or discrete concurrent feedback during acquisition, retention, and transfer of a 90° phase offset bimanual coordination pattern. The authors tested both groups immediately following acquisition, 1 week later under retention conditions (i.e., identical feedback as acquisition) and under transfer conditions with a change in feedback (i.e., discrete to continuous or vice versa) and with no feedback. Acquisition results revealed superior performance by the continuous feedback group. However, during immediate transfer conditions, the continuous group showed decreased pattern accuracy and stability, whereas the discrete group improved its performance. These results support the guidance hypothesis, as the participants with a high amount of feedback in acquisition became reliant on the feedback and could not adapt their learning to a new situation. These results also show partial support for the specificity of practice hypothesis as the continuous group was only able to mimic their acquisition performance under identical conditions as practice. Practice specificity effects were not found for the discrete group, as performance was not negatively affected with a change or removal of afferent information.

In a serial reaction time task, participants practiced a repeating sequence with 1 hand. In interleaved blocks, they responded to random sequences with the other hand. Experiment 1 was composed of 5 sessions, each consisting of 30 blocks. Intermanual transfer, reflecting a hand-independent component of sequence knowledge, increased across session. A smaller but significant, nontransferable, and...

Computerized tasks allow a more fine-grained analysis of the strategy deployed in a task designed to map a specific ability than the usual assessment on the basis of only the level of performance. Manipulations expected to impair performance sometimes do not have that effect, probably because the level of performance alone can confound the assessment of the ability level if researchers ignore t...
