Activity in the faster condition was significantly lower than in the same rhythm condition (faster vs. same rhythm: t23 = 2.1, P = 0.046).
We did not find primary sensory increases in the faster condition relative to the same or slower conditions, suggesting that primary area increases may only occur for more basic expectancy violations, rather than predictions of the higher level features like the beat.
The child was asked to drive the cursor out of the maze as fast as he could without touching the labyrinth's walls (FASTER condition) or to try not to "hit" the walls while running the maze (ERROR condition).
Under FASTER condition, shoulder range of motion was again significantly higher in children attending first grade than in those attending second grade (p=0.0003).
Under FASTER condition, all children used mainly movements of the elbow to complete the task, except for the younger (first grade) that used the same motor strategy described under ERROR condition (i.e. they used mainly shoulder movements).
The first line shows shoulder, elbow and wrist angles of children attending first and fifth class under ERROR condition, while the second line shows the same parameters under FASTER condition.
