FIG. 6.

(Color online) Box-and-swarm plots of between-condition differences in listener sensitivity for experiment 2. Boxes show first and third quartiles and median values; individual data points correspond to each listener; asterisks indicate comparisons with corresponding coefficients in the statistical model that were significantly different from zero. (a) Main effects of attention (higher sensitivity in maintain than switch trials), spectral degradation (higher sensitivity in 20-channel than 10-channel vocoded trials), and switch gap duration (higher sensitivity in trials with a short gap). (b) Two-way interactions: the difference between long- and short-gap trials was greater (more negative) in the ten-channel-vocoded trials and in the maintain-attention trials. (c) Three-way interaction (not significant). * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
