a. Scatterplot of the relationship between mean auricular movement for the facilitation phase and the mean auricular movement achieved on the post-test sessions for the skill acquisition phase for Learners (solid circle) and Poor/Non-learners (solid triangle). Spearman’s rank correlation coefficient, R² = 0.84, p = 0.004. b. Scatterplot of the relationship between mean auricular movement on the post-test after the first facilitation session (sensory session 1) and the first skill acquisition session with the games (session 10). Notice two different linear fits—one for Learners (solid circles) and one for Poor/Non-learners (solid triangles). Note that ID# 7 (a Learner, solid circle) is clustered among the Poor/Non-learners (solid triangles)
