Systematically profiling and tracking of 12 prominent keyword/themes across the corpus. The count of each theme within the maximal nodes per year was isolated, and transformed into a percentage of the total year publications – providing a standardized metric. The inflection year (2006; see Figure 2), and the year of maximal occurrence for that theme (as denoted by the dashed vertical line) are referenced for contextual understanding. In addition, a line of best fit is empirically derived and illustrated for each theme, demonstrating the continued growth across the academic arena for all themes with the exception of Infant, Behavior and Language and Communication.
