- Titre : Repetition in visual word identification: Facilitation or inhibition?
- Abstract : In lexical processing, when target words are identified within several seconds of presentations of a prior reading of the word (identity prime), responses to targets are facilitated relative to an unrelated-prime control. However within the attentional and memory literatures, minor procedural changes produce identity priming costs for targets. Four experiments evaluated the claims of Huber and colleagues that reading a word produces habituation, a brief decrease in the susceptibility of the lexical representation to activation. Consistent with Huber's account, two experiments with brief masked targets showed repetition benefits in identification and word-nonword classification when the interval was too short for habituation to be established (50 ms), whereas repetition costs were found at a longer SOA (500 ms). Experiments 3 and 4 indicated that these results depended on masking of targets and high perceptual similarity of primes and targets. The results are more consistent with an effect of identity priming on the establishment of separate episodic records of the prime and target, as suggested in accounts of repetition blindness in rapid serial visual presentation (RSVP).
