Prose Representation: A Multidimensional Scaling Approach

Multidimensional scaling was employed to study the comprehension of prose. Subjects rated the similarity between pairs of 20 nouns before reading. After reading a passage containing the nouns, the subjects re-rated the words with respect to similarity within the passage. Subjects then recalled the passage. The similarity ratings were analyzed by multidimensional scaling. The results indicated that the scaling analysis provided an effective, valid indicator of prose representation. The multidimensional structural characteristics of dimension interpretation, clustering, and centrality were interpreted in terms of the theme, episodes, and central organizing feature of the story, respectively. Theoretically, the analysis indicated that comprehension was a function of the passage organization mapping onto the existing memory structure superimposed upon and suppressing the prior conceptual structure.
