Neural Mechanisms of Self-Generated Action Sequences.

The results confirmed a highly significant monotonic decrease in the self-generated preparatory advantage from the first to the final move ( p < 0.0001; cluster mass = −1,779.65; −1,000 to +495 ms), indicating that preparatory activity became progressively less self-specific as the sequence unfolded ( Fig. 3 , right panel).

However, the magnitude of this effect showed a numerical decrease across positions in the 4-move sequence, although this trend did not reach statistical significance.
