Behavioral results. A: accuracy of imitation. Segment orientation error is plotted against segment serial position for each one of the stimulus presentations. Error bars are within-subject SE (Cousineau 2005; Loftus and Masson 1994). B: practice and sequence-specific effects. Each group of bars represents data from one experimental session (numbered chronologically). Ordinate values are mean error across all segments in the stimulus sequences. Red, green, and blue bars denote the first, second, and third sequence presentations, respectively. Error bars are within-subject SE for each session.
