Abstract

Research suggests that patients with aphasia perform significantly poorer than neurologically normal subjects in all areas of symbolic recognition except for via iconographic symbols. This work is an expansion of a previous study on an environmental symbol recognition test (ESRT). Stimuli on the ESRT include company logos, highway signs, and environment ideograms. Results indicate a significant difference in performance between the neurologically normal (N=41) and neurologically impaired (N=82). Between group comparisons were also found to be significant (i.e. TBI, L Hemisphere w/aphasia). Further, comparison with Aphasia Diagnostic Profile (ADP) performance for a subset of neurologically impaired subjects, yielded significant correlations between ADP subtests and the ESRT score.
