Means of average response time as a function of task (imitation and complementary action) for normal trials (dotted lines) and color test trials (solid lines). The data presented here are (a) from the study conducted by van Schie et al. (2008, Experiment 2) and our study (b, c) depicting the data for all trials and first trials, respectively. The test trials included predefined actions (either a precision grip or a full grip) independently of the action of the virtual actor. In this way, the action executed by the participant could either be the same as (filled squares) or opposite from (unfilled squares) the action of the virtual actor
