Word Frequency Effects in Dual-Task Studies using Lexical Decision and Naming as Task 2

Remington, R., McCann, R.S., & Van Selst, M.

Word frequency effects in dual-task lexical decision are variously reported to be additive (McCann & Remington, 1995) or under-additive (Van Selst, Besner, & Jolicoeur, 1994) across SOA. We replicate and extend earlier lexical decision studies and find word frequency to be additive across SOA. To more directly capture lexical processing, we examine dual-task naming. Once again, we find word frequency to be additive across SOA. Lexical processing appears to be constrained by central processing limitations (Pashler, 1995).
