The Table shows performance of patient groups as odds ratios (95% confidence intervals) referenced to healthy control group performance on the control tasks and auditory scene semantic and emotional congruity tasks; analyses of congruity test performance for each participant were based on scene stimuli containing sounds that were both individually identified correctly by that participant. Odds ratios with confidence intervals overlapping 1 indicate performance not significantly different from healthy controls; bold denotes significantly different from healthy controls (p < 0.05). ScEc, semantically congruous - emotionally congruous; ScEi, semantically congruous - emotionally incongruous; SiEc, semantically incongruous - emotionally congruous; SiEi, semantically incongruous - emotionally incongruous. bvFTD, patients with behavioural variant frontotemporal dementia; SD, patients with semantic dementia. Raw data are summarised for all tests and participant groups in Table S3 in Supplementary Material on-line.
