FIG. 4.

The coupling profiles for each phonemic context were subjected to a multidimensional scaling (MDS) procedure to derive an articulatory coordination space based on pellet coupling. This analysis provided a means to evaluate task specificity of lingual deformation patterns by reducing the multivariate data associated with each task into three factors or dimensions. Similarities among coupling profiles across place of articulation and task are represented by spatial proximity. Panel (a) shows the MDS solution plotted as Euclidian distances from a common centroid. Panel (b) shows the individual participant weights for each dimension.
