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.

Francis http://works.bepress.com/wendy_francis/4 http://works.bepress.com/wendy_francis/4 Fri, 25 Jan 2008 22:45:09 PST Two experiments with highly fluent Spanish-English bilinguals examined repetition priming of picture identification and word retrieval in picture naming. In Experiment 1, between-language priming of picture naming was symmetric, but within-language priming was stronger in the non-dominant language. In Experiment 2, priming between picture naming and translation was symmetric within the dominant language and within the non-dominant language, but priming was stronger in the non-dominant language. A mathematical model required only three process parameters to explain the pattern of priming across eight conditions. These results indicate that shared processes are the basis of priming, that difficulty influences priming only at the process level, and that translation in both directions is concept mediated in fluent bilinguals.
