According to the APA’s controlled vocabulary, the meaning of the Self Regulation index term is interpretable through the definitions of seven related terms: Agency,Emotional Regulation (used for affect regulation), Self Control (used for willpower),Self Management, Self Monitoring (used for self observation), the parenthetically named Self
Monitoring (Personality), and Self Regulated Learning. Each of these is then interpretable through their own sets of related terms, expanding the total number of implicated definitions to 49. And the meanings of this second-order set can be anchored,
topographically, such that the total number of terms considered is 447—all of which are distinct and locatable. (This anchoring is crucial for the method of visualizing meanings used in Study 2: terms linked-to by other relevant definitions will be drawn in closer to each other by the layout algorithm, while terms not linked-to will be pushed outward to the periphery, preserving topographical centrality and proximity as simple heuristics in interpreting meanings.)
