(A) S_IC(t) function for one exemplary participant in the pilot study. This participant showed evidence for parallel first-terminating processing (as did three other participants). Only one participant produced an S_IC(t) consistent with another model, which was coactive processing. (B) The capacity results computed for the same participant. C(t) was computed across all saliency levels (i.e., the integrated hazard functions from the AV, A-only, and V-only conditions included RTs from each level of saliency). Each participant yielded strong evidence for extremely limited capacity, a finding inconsistent with coactivation, but consistent with a parallel model with cross-channel inhibition.
