Fig. 2. Construction of the semantic network of risk.

(A) Mini-snowball word association approach used to generate level 1 and level 2 associates of the word “risk” (numbers represent each of the 30 word associates provided by each respondent). (B) Level 1 by level 2 co-occurrence matrix, which served as the basis for determining the relatedness among the level 1 responses (numbers represent unique associates). (C) Relatedness matrix between level 1 associates, determined by calculating the Jaccard similarity between rows in the co-occurrence matrix shown in (B) and ordered according to a clustering algorithm (see main text for details; C, component). The asterisk (*) indicates that only the subset of level 1 associates are included that were produced at least three times across all participants.
