The ``BIG BIRD'' of the ``YELLOW YOUNG'' man: Do nontarget properties cascade?

This study investigated whether in speech production object properties flow in a cascaded manner or whether cascaded processing is restricted to the object's identity. In Experiments 1 and 2, participants saw pictured objects and had to state either their size (GRAND or PETITmeaning big and small) or their name. The size of the objects varied as a function of the way they were presented on the computer screen (Experiment 1) or their real size in the world (Experiment 2). In Experiment 3, faces of young and old men were coloured in yellow or in green. The task was to name either the colour (JAUNE or VERT, meaning yellow and green, respectively) or the age (JEUNE or VIEUX, meaning young and old, respectively) of the face. In Experiments 1 and 2, no reliable effects of phonological relatedness (GORILLE-granda big gorilla) were found on the object-naming latencies. However, size-naming latencies were shorter when the adjective shared the initial phoneme of the picture name (i.e., GRAND-gorille) than when it did not (i.e., GRAND-dinosauresaying big in response to a big dinosaur). In Experiment 3, phonological overlap did not affect colour naming latencies, or age naming latencies. Overall, these findings strongly suggest that cascaded processing is restricted to the object's identity in conceptually driven naming tasks.
