Automatic and strategic processes in picture naming

Prior presentation of related priming stimuli can facilitate responding to subsequent targets. However, recent research has demonstrated that inhibition effects can be produced by related primes when some of the primes in the testing sequence directly name their targets. This study used a picture-naming task, manipulating strength of relation between the prime word and the target picture, and the presence of identical primes in the testing sequence. Related primes facilitated naming when identical primes were absent, but not when they were present, whereas the strength effect did not vary as a function of identical-prime presence. A second experiment replicated the strength effect and showed that it was not affected by the presence or absence of primary associates in the testing sequence. A comparison-strategy explanation of the inhibition effect is proposed, in which the strategy is superimposed on an automatic activation of related information.
