Measuring and Training Speech-Language Pathologists’ Orofacial Cueing: A Pilot Demonstration

Figure 3

GPA analysis as applied to S-LP's thumb finger movement trajectories over successive trials of stimuli “ta-ti-ta-tu”. Since the movement paths are rotated, the trajectories after GPA do not correspond to the original movements in the Cartesian axis. Hence, by convention, we use the principal axes of the GPA consensus path in the plots. Data from (a) S-LP 1, (b) S-LP 2, and (c) S-LP 3.
