Visual word recognition: Effort after meaning but not (necessarily) meaning after effort.

A robust semantic priming effect typically occurs in visual word recognition if the prime is read prior to a response to the target. M. C. Smith, D. Besner, and H. Miyoshi (1994) reported that this semantic priming effect is markedly reduced for short-duration primes randomly intermixed with longer duration primes, and they offered a signal-detection account of their results. This general finding is replicated and extended in 3 experiments, which demonstrate the importance of list context for this prime duration effect and suggest that a center-surround attentional mechanism provides a better account of the results to date.
