The ability to perform relational proposition-based reasoning was assessed in younger and older adults using the transitive inference task in which subjects learned a series of premise pairs (A>B, B>C, C>D, D>E, E>F) and were asked to make inference judgments (B?D, B?E, C?E). Learning of premise pairs was related to subsequent inference performance and conscious awareness of the stimulus hierarchy (A>B>C>D>E>F). Despite extended training, age-related deficits were observed for response times… CONTINUE READING
