Neural mechanisms of lipreading in the Polish-speaking population: effects of linguistic complexity and sex differences

Description: Unthresholded and unmasked group-level contrasts of interest in lipreading fMRI task. Task conditions included materials spoken by a voice actress: 1) naturally together with sound (audiovisual lexical); 2) naturally, but without sound (visual lexical); 3) a clip played backwards and without sound (visual non-lexical). In addition, to investigate the role of the type of linguistic material on the lexical processing of visual stimuli, each of the above conditions was implemented in the form of either complete sentences or strings of words. As a control condition, we used a still photo of the voice actress with no acoustic stimulation.
