Affective valuation of spoken numbers by participant groups and in patients versus healthy controls. In the left panel, individual participants' average affective valence ratings of spoken numbers are plotted within each participant group. The right panel shows mean differences (with 95% confidence intervals, adjusted for multiple comparisons with Bonferroni correction of p-values) in rated valence between each patient group and the healthy control group; the horizontal dashed line indicates the zero level corresponding to no difference between patient group and heathy control group. AD, patient group with typical Alzheimer's disease; BV, patient group with behavioural variant frontotemporal dementia; HC, healthy control group; NFV, patient group with nonfluent-agrammatic variant primary progressive aphasia; SV, patient group with semantic variant primary progressive aphasia.
