Does conal prime CANAL more than cinal? Masked phonological priming effects in Spanish with the lexical decision task.

subject

description

Evidence for an early involvement of phonology in word identification usually relies on the comparison between a target word preceded by a homophonic prime and an orthographic control (rait-RATE vs. raut-RATE). This comparison rests on the assumption that the two control primes are equally orthographically similar to the target. Here, we tested for phonological effects with a masked priming paradigm in which orthographic similarity between priming conditions was perfectly controlled at the letter level and in which identification of the prime was virtually at chance for both stimulus onset asynchronies (SOAs) (66 and 50 msec). In the key prime-target pairs, each prime differed from the target by one vowel letter, but one changed the sound of the initial c, and the other did not (cinal-CANAL vs. conal-CANAL). In the control prime-target pairs, the primes had the identical vowel manipulation, but neither changed the initial consonant sound (pinel-PANEL vs. ponel-PANEL). For both high- and low-frequency words, lexical decision responses to the target were slower when the prime changed the sound of the c than when it did not, whereas there was no difference for the controls at both SOAs. However, this phonological effect was small and was not significant when the SOA was 50 msec. The pattern of data is consistent with an early phonological coding of primes that occurs just a little later than orthographic coding.
