FIGURE 2.

Results for sensitivity and motor priming+interference effects produced by action observation. (A) Measure of sensitivity (d-primes) for the FDI and ADM brain responses to action observation. Sensitivity for the FDI was significantly different from 0. (B) Group average for MT for the congruent (where the stimuli were the video showing a movement involving the effector used to respond; dark gray) and incongruent (where the stimuli were the video showing a movement not involving the effector used to respond; light gray) conditions for the index and little finger. For the index finger, mean MT for the congruent condition was significantly shorter than the MT for the incongruent condition. Error bars represent standard error of the mean. *p < 0.05. FDI, first dorsal interosseus; ADM, the abductor digiti minimi; MT, movement time.
