Gap detection thresholds as a function of the characteristics of the temporal fringe. The core, consisting of the synchronously gated signal band and four comodulated flanking bands, had a temporal fringe of either the same five comodulated bands (All Com.), the signal band alone (Single), or five random bands (All Ran.). Data are shown in separate panels for staccato noise and Gaussian noise. In each panel group means are shown by large symbols, ± 1 standard deviation, with individual data points clustered to the side of the respective mean.
