Cross modal and linguistic interactions in speech perception Sophie Scott, Carolyn McGettigan, Irene Altarelli, Jonas Obleser, Andy Faulkner, Stuart Rosen

Speech comprehension is influenced…. By concurrent visual information By higher order linguistic information by the acoustics of the speech signal

The neural basis of this varies 1 2 3 4 8 16 3R 16R Effect size (%) Acoustic detail 0 1 2 4 8 0 1 2 4 8 0 1 2 4 8 30 pixels 18 pixels 6 pixels channels C Face and voice interaction Predictability effects

Proposed study Vary these three factors within one study Acoustic detail, facial blurring, linguistic predictability Sparse scanning, 3X2X2 design (2,4,6 channels, 15 and 45 levels of Gaussian blur, and low and high predictability), plus a severe blur/continuous noise condition. TR 9 seconds 260 trials in total, 20 sentences per condition, and 20 ‘baseline’ trials - 2 blocks of 20 mins?
