Abstract

Cognitive mechanisms underlying repetition priming in picture naming were decomposed in several experiments. Sets of encoding manipulations meant to selectively prime or reduce priming in object identification or word production components of picture naming were combined factorially, in order to dissociate processes underlying priming in picture naming. Experiments 1, 2, and 3 were conducted with Spanish-English bilingual participants and bilingual materials. Experiments 4, 5A, and 5B were single-language experiments in English and Spanish. A simple process model was used to formalize the theoretical predictions and test them across all experiments simultaneously. Object identification and word production processes were selectively influenced in an additive manner, which suggests that the two sets of processes are independent and sequential. The patterns of facilitation support a quantitative model of transfer-appropriate processing in which shared processes from encoding to test are the causal basis and speeded processes are the mechanism of facilitation.
