Abstract

Lexical frequency effects were examined in the context of the central bottleneck (CB) model of dual-task performance. Two dual-task experiments were conducted. In Experiment 1, picture naming was the primary task and tone identification was secondary. Lexical frequency affected reaction time (RT) to both tasks similarly. In Experiment 2, task order was reversed, and, after controlling for variables including name and image agreement, frequency affected naming RT similarly at all levels of stimulus onset asynchrony. These results are consistent with prior studies localizing frequency effects in word naming to the central, response selection stage of the CB model.
