Abstract
This thesis examines the effect of time delay and intervening items on masked repetition studies with word stem completion tasks. In the first experiment a masked priming effect was obtained. The effect was strongest 500ms after the presentation of the prime, and decreasing in a linear trend seven seconds after the presentation of the prime. The second experiment found that interpolating a naming task between the masked prime and the stem completion task eliminated the effects of the repeated masked prime. This result is a failure to replicate previous research which found a masked repetition effect over a short delay with intervening items. These results are interpreted as supporting the contention that masking a priming stimulus excludes formation of a trace in the episodic memory system and so provides an insight into the functioning of the lexical processing system. It appears that priming the lexicon with a masked stimulus leaves the system activated for at least 7s and the decay of this activation is a time dependent process.
