*Denotes impaired performance. * ≤ 0.05, ** ≤ 0.01, *** ≤ 0.001 using a modified t-statistic to examine whether an individual is significantly below a control group, taking into account control group size, mean and standard deviation (Crawford et al., 2010). Control performance and normal cut-offs taken from the following published texts except where stated.
aNorms for analysis taken from spoken word-picture matching using the same stimuli. Spoken Word-Picture Matching (WPM) from the Cambridge Semantic Battery (Bozeat et al., 2000); Synonym judgment (Jefferies et al., 2009); Environmental Sounds Test (Bozeat et al., 2003); CCT = Camel and Cactus task in picture and written word forms (Bozeat et al., 2000); PPT = Pyramids and Palm Trees task in picture and written word forms (Howard and Patterson, 1992); NT = not tested; WA = Wernicke’s aphasia; SA = semantic aphasia; TP = temporoparietal; PF = prefrontal.
