| summary | 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 assessed the conditions that produce costs and benefits. The aim was to evaluate 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 Huberπs account, Experiment 1 showed that perceptual identification benefits were found when the interval was too short for habituation to be established (50 ms), whereas repetition costs were found at a longer SOA (500 ms). Experiment 2 showed broadly
similar effects in a target-masked version of the LDT (target displayed for only 80 ms). Experiment 3 showed that these results depended on masking of targets, with identity priming facilitation observed at the 500 ms SOA in the conventional LDT (target displayed until response). Experiment 4 showed that the identity priming cost in the masked-target LDT was reduced when primes and targets were presented in different letter case. The results are
not consistent with Huberπs proposal that habituation is the usual consequence of word identification. Instead the results indicate 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). |
