Fig. 2.

Comparing intelligibility contrast (SP > RS) across the echoes. 2a). Showing results from short (green) and long (red) echoes, with overlap in yellow. The circle highlights the contribution of short echo within inferior temporal regions, compared to long echo. 2b). Showing dual-echo data and the comparison between its constituent parts, highlighting the inferior temporal region. Scale showing t-value range (2–6) for a) and b). The bar graph shows the contrast estimates for intelligibility within an independent regions-of-interest (ROI; 8 mm sphere at − 42 − 16 − 34 (Crinion et al., 2003). The first three columns represent the data with standard SPM masking (suffix _M) and last three columns show the data without masking. The dual and short echo is always significantly larger than the long echo (all p's < 0.025), while there is no difference between the dual and short echoes.
