Figure 1. Experimental Design of the fMRI Adaptation Paradigm in Experiment 1.

Figure 1

(A) In the “Execute-Observe” runs, blocks comprised a series of “Execute” trials followed by an equivalent number of “Observe” trials. “Execute” trials required participants to commence a cued action at the onset of a central fixation dot. “Observe” trials required participants to passively observe a presented action. The observed actions were either the same as those previously executed (as illustrated), or different from them.

(B) The “Observe-Execute” runs reversed the order of “Execute” and “Observe” trials.
