Overview Description of Contents Categories by Alphabet Group Equivalence Category Type Comparison Statistics Affinities, Correlations Publications	Overview of Research Normative data are collected for 105 verbal categories for younger and older adults in Beijing, China and in Ann Arbor, Michigan. One hundred subjects in each culture-by-age group were tested separately in sessions of 5 to 25 participants each. The tested categories represent relatively common knowledge structures in both cultures (e.g., nonalcoholic beverage, color, internal organs), with many of them selected from previous norming studies conducted on younger American adults (e.g., Battig and Montague, 1969; McEvoy and Nelson, 1982).  For each category, subjects were asked to list 5 items belonging to that category, in whatever order they occurred to them. Response probabilities and frequencies were calculated for each category and analyzed for convergence as well as differences as a function of culture and age. Possible applications of the category norms for cross-cultural and cognitive aging research are discussed. The project makes three distinct contributions.  First, we specify which categories generalize across Age groups, which across Cultural groups, and which across both, rigorously quantifying differences across them.  Second, we introduce a powerful methodology to analyze freely generated data – combining the rank-ordered logit model and Hellinger Affinity – to measure the degree of between-group differences.  Finally, a broad archive of tested, cross-linguistic stimuli is now available to researchers:  the raw and fully analyzed data for all 105 categories and each of the four groups – comprising over 10,000 unique item responses – translations, similarity measures and stimulus materials are freely archived at this web site (see Description of Contents).
