AB - Two experiments with 28 Ss (aged 18–26 yrs) used versions of S. Sternberg's item-recognition task, in which S could make a decision by semantic categorization or by a search of short-term memory. When a single category distinguished the words of a memory set from foils, pronounced deviations from a linear set-size effect were observed. Decision times were affected little by increases in set size beyond 3 or 4, suggesting that a categorization process was circumventing an item-by-item search of memory. Results were observed in the absence of a consistent mapping between stimuli and responses; in other words, within a session the relevant category constantly changed and stimulus words were used as both targets and foils. Results are compatible with a race model in which memory scanning and semantic categorization occur in parallel; the decision time is determined by the process reaching completion first. (18 ref)
