WOLTER, Rafael Pecly    WACHELKE, João. Complementary indexes to study a social representation from free evocations data: rarity, diversity and community. []. , 15, 2, pp.119-129. ISSN 1516-3687.

This paper aims at presenting three indexes that can be calculated from free evocation data. Two of those indexes were elaborated by Flament and Rouquette (2003), and they indicate the diversity and rarity degrees of evocations. The third index allows for the study of the proportion of elements common to two evocation corpora. From these three indicators it is possible to have information about the degree of social sharing of each object, their idiosyncrasy level and the community proportion between two corpora. When associated with other techniques, such information might be useful for a better understanding of the population-object relationship.
