A priming experiment was conducted to investigate how semantic context affects the perception of a briefly exposed Kanii target. On each trial, a Kanii or a plus (neutral) was presented as the prime stimulus for 1s. When the prime was a Kanii, subjects were required to imagine any compound word, the first letter of which was to be that prime. After a blank of 500 ms, a target Kanii was briefly exposed followed by a patterned mask and two response alternatives, one of which the subject was asked to choose. The duration of the target was so adjusted that each subject could respond correctly at approximately 75% level. The % choice response was higher when the prime and the target made up a compound word (related condition) and also matched to the imagined word (facilitation) than when not (neutral condition). When the prime and the target were unrelated, the performance was the worst (inhibition). In the related condition, however, responses were more accurate even when the prime-target pair did not match to the imagined compound word than in the unrelated condition. These results suggest that semantic priming effect occurs automatically regardless of whether the subject may expect the target or not.
