Now you see it, now you don't: on turning semantic interference into facilitation in a Stroop-like task.

We use a masked priming procedure to test two accounts of the picture-word interference (PWI) effect: the lexical selection by competition account (Levelt et al., 1999; Roelofs, 1992) and the response selection account (Lupker, 1979; Miozzo and Caramazza, 2003). In the visible (standard) condition, we replicated the often-observed semantic interference effect. In the masked condition, we observed semantic facilitation. We take the polarity shift as a function of masking to mean that the semantic interference and semantic facilitation in the PWI task should be attributed to two qualitatively different processes. We argue that this conclusion follows naturally from the response selection account, but only with great difficulty from the lexical selection by competition account.

Lexical selection in bilingual speech production does not involve language suppression.

The "hard problem" in bilingual lexical access arises when translation-equivalent lexical representations are activated to roughly equal levels and, thus, compete equally for lexical selection. The language suppression hypothesis (D. W. Green, 1998) solves this hard problem through the suppression of lexical representations in the nontarget language. Following from this proposal is the prediction that lexical selection should take longer on a language switch trial because the to-be-selected representation was just suppressed on the previous trial. Inconsistent with this prediction, participants took no longer to name pictures in their dominant language on language switch trials than they did on nonswitch trials. These findings indicate that nontarget lexical representations are not suppressed. The authors suggest that these results undermine the viability of the language suppression hypothesis as a possible solution to the hard problem in bilingual lexical access.

The role of language in memory for actions.

Languages differ with respect to how aspects of motion events tend to be lexicalized. English typically conflates MOTION with MANNER, but Japanese and Spanish typically do not. We report a set of experiments that assessed the effect of this cross-linguistic difference on participants' decisions in a similarity-judgment task about scenes containing novel animations as stimuli. In Experiment 1, which required participants to encode the stimuli briefly into memory, we observed a language effect; in Experiment 2, which required participants to analyze the same stimuli, but not remember them, the language effect disappeared. Hence, these experiments reveal a task-dependent effect, which, we argue, points to working memory as the source of the language effect observed in Experiment 1 and, potentially, other experiments that have shown a linguistic relativity effect.
