Average across the subjects’ mean grip force (N) for trials with a significant influence of trial history, where LU means the modulation of unlinked trials which follows linkage (and similarly for other trial types) (N=6). (a and b) Condition Linked-Unlinked; (c and d) condition Linked-External; (e and f) condition External-Null. The vertical dashed line is the time of peak load force (or for the unlinked trials time of expected peak load force). Subjects’ mean grip force modulation (N) for each of the three conditions dependent on the previously experienced trial with all trial types shown (a and b) condition Linked-Unlinked c-d) condition Linked-External. (e and f) Condition Null-External. Error bars show S.E. individual means (N=6) ((*) significant at p<0.05; (***) significant at p<0.005).
