Asp et al. Neural correlates of credulity FIGURE 2 | Lesion overlap of brain damage comparison patients. The overlap map shows the lesions of BDC patients displayed in ventral/lateral views and coronal slices (a–f, with the right hemisphere on the left in the coronal views). The color bar indicates the number of overlapping lesions per voxel. younger and had more females relative to males than our vmPFC group and normal group (Table 1), so we corrected for these differences in the main analyses. VMPFC patients had signiﬁ- cantly larger lesions relative to BDC patients (Table 1); thus, a secondary analysis directly comparing credulity in the BDC and vmPFC groups was conducted to account for lesion size. Par- ticipants with signiﬁcant language, memory, or visuoperceptual deﬁcits which might impair their ability to adequately complete the task were excluded. We excluded patients with signiﬁcant aphasia (deﬁned as two standard deviations below the mean on the Boston Naming Test or the Token Test), reading deﬁcits (deﬁned as two standard deviations below the mean on the Iowa Chapman Read- ing Test), memory deﬁcits (deﬁned as two standard deviations below the mean on the Auditory Verbal Learning Test delayed recall or the Complex Figure Test delayed recall), or visuoper- ceptual impairments (deﬁned as two standard deviations below the mean on the Facial Recognition Test). There were no signiﬁ- cant differences between vmPFC and BDC patients on the various neuropsychological measures (Table 2).
