Object and action picture naming in brain-damaged Persian speakers with aphasia

Abstract

Background: Individuals with aphasia can be impaired in action and object naming and most typically are more impaired when naming actions than objects. However, it is not clear if effects of grammatical class are language-general as assumed by some theories of speech production. Aims: We predicted greater impairments to action than object naming in persons with aphasia (PWA) in Persian. However, we expected any effect of grammatical class to be reduced when highly correlated variables are accounted for using generalised linear mixed-effects analysis. Methods & Procedures: PWA (n = 57) were presented with pictured actions (n = 80) and objects (n = 100) rated by 100 Persian speakers in a prepa..
