Repeated presentations were made of a paired-associate list, with the stimulus and response member of each pair exposed simultaneously. Each pair was presented for a total of 20 or 40 sec., with an exposure time per trial of 2, 5, 10, 20, or 40 sec. Results of a recall test indicated that amount learned varied directly with total exposure time, but that, contrary to Bugelski's total-time hypothesis, more was learned with shorter, than longer, exposures per trial at each total exposure time.
