Episodic and lexical contributions to the repetition effect in word identification.

摘要: SUMMARY The repetition effect refers to the finding that speed and accuracy of naming a visually presented word is enhanced by single prior presentation word. A new technique was developed study this phenomenon: visual signal-to-noise ratio printed item in field masks slowly increased. When interest, increase ceased at predetermined time; when latency continued until could be named. Experiment 1 tested validity against more traditional threshold measure ease identification, which for brief exposure, followed mask. performance levels first were equated two techniques both words nonwords, equal slightly stronger than nonwords. In la psychometric functions presentations obtained, giving as function final exposure duration. large interaction seen with yielding superior technique, but reverse true 2 version used: difference in'the latencies necessary nonword identification found additive due repeated presentations.
