Abstract

The goal of the present effort was to revisit Miller’s (1982) claim that audio-visual stimuli are processed by a coactive architecture. We replicated Miller’s analysis and extended it using both group and individual level measures from Systems Factorial Technology (SFT; Townsend & Nozawa, 1995). Similar to previous findings, some participants exhibited redundancy gain beyond that predicted by independent parallel processing. However, the majority of participants performed no better than would be predicted by an independent parallel model, and some even performed worse than independent parallel. Furthermore, the variation observed across individual participants suggests that individual level performance measures are at least as important as group measures for the robust interpretation of human information processing data.
