Scott Grafton and colleagues (1995)discovered that implicit versus explicit learning of a motor sequence produced differing patterns of brain activation.The overall conclusion reached in this study was that
A)it is easier for participants to learn a motor task implicitly than to learn the task explicitly.
B)differences in brain activation patterns were all due to the effect of practice,such that participants who received more practice on the motor task produced less overall brain activation.
C)participants who were aware of the sequence showed subcortical activity when performing the task,whereas participants who were unaware of the sequence showed only cortical activity when performing the task.
D)separate brain systems appear to be involved in the regulation of explicitly learned versus implicitly learned motor skills.

The study by Scott Grafton and colleagues discovered that implicit and explicit learning of a motor sequence produced differing patterns of brain activation, suggesting separate brain systems are involved in regulating explicitly learned versus implicitly learned motor skills. This is the overall conclusion of the study. Option A and B are not supported by the evidence from the study, while option C is too narrow and does not account for the full range of findings.
