Effects of lexical frequency (LFW > HFW) during lexical decision and reading aloud
| Region and effect | x, y, z | Lexical decision (LFW > HFW) | Reading aloud (LFW > HFW) | Interaction with task (LFW > HFW) | ||
|---|---|---|---|---|---|---|
| Z | Voxels | Z | Z | Voxels | ||
| Left dorsal opercularis | −46, 18, 22 | 4.2 | 122 | n.s | 3.8 | 16 |
| Anterior cingulate/SMA | −4, 22, 42 | 4.1 | 83 | n.s | 3.6 | 9 |
| Pre‐SMA | −2, 10, 58 | 4.0 | 28 | n.s | 4.0 | 33 |
x, y, z = coordinates of local maxima; Z = Z scores; voxels = number of voxels at P < 0.001 uncorrected. Z scores significant at P < 0.05 (corrected for multiple comparisons) when search limited to those areas activated over and above baseline, and cluster size significant at P < 0.05 (corrected for multiple comparisons) are reported in bold. HFW: high‐frequency words. LFW: low‐frequency words. n.s. indicates not significant if did not reach at least the combined uncorrected threshold criteria of height P < 0.001 and voxel extent P < 0.05. The effects of HFW > LFW were not significant in lexical decision and in reading aloud.
