fMRI activation results in regions of interest. The contrast labels (a to f) in the first column correspond to those detailed in ​Table 1. ‘x’ ​denotes the testing of an interaction. The regions of interest are centred on the areas reported in ​Agnew et al. (2013) ​for own versus another’s speech in right pSTS (RpSTS) (x ​= ​+48, y ​= ​-31, z ​= ​+1) and other versus own speech in left STG (LSTG) (-60 -13 ​+ ​4). Effects are also reported in the homologues of these regions: left pSTS (LpSTS) (-48 -31 ​+ ​1) and right STG (RSTG) (+60 -13 ​+ ​4). P-values are corrected for multiple comparisons across the whole brain, unless appended with a u (i.e. p ​< ​0.001u) which indicates uncorrected thresholds or * which indicates a small volume correction for multiple comparisons in the regions of interest and for the effects of interest (i.e. RpSTS for speech production ​> ​auditory processing and LSTG for auditory processing ​> ​speech production). ns = not significant.
