The distractor picture paradox in speech production: evidence from the word translation task.
Several naming studies show that distractor pictures, even when intentionally ignored by the speaker, are still capable of activating their respective phonological representations. However results from word translation studies suggest that distractor pictures are only conceptually activated. Here we tested the reliability of the word translation results. In four experiments, bilingual participants translated words from one language to the other one while ignoring the presentation of pictures. In Experiment 1a phonological related pictures sped up translation latencies. However, the effect disappeared when the percentage of related trials was reduced (Experiment 1b). In Experiment 2a translation latencies were faster when the words were accompanied by semantically related pictures than by unrelated pictures. Importantly, the effect was still reliable when the proportion of related trials was reduced and the total number of semantic categories was increased (Experiment 2b). Theoretical implications of the influence of distractor pictures during speech production are discussed.
