Figure 5. Averaged Scores of Lip Smacking on Days 1 and 3 and of Tongue Protrusion on Day 3 and of the Same Behaviors Scored in the Other Experimental Conditions.

Averaged scores are calculated as the difference between the frequency of the imitated behavior in the stimulus period and the baseline. The asterisk (*) indicates a significant difference of LPS score in the MO compared with TP and HO conditions. Pound symbols (#) indicate a significant difference of the behavioral score recorded in that condition compared with all the other conditions. Scores are ± standard error of the mean.
