  • Title: The comprehension of ambiguous idioms in aphasic patients.
    Author: Cacciari C, Reati F, Colombo MR, Padovani R, Rizzo S, Papagno C.
    Journal: Neuropsychologia; 2006; 44(8):1305-14. PubMed ID: 16504224.
    Abstract:
    The ability to understand ambiguous idioms was assessed in 15 aphasic patients with preserved comprehension at a single word level. A string-to-word matching task was used. Patients were requested to choose one among four alternatives: a word associated with the figurative meaning of the idiom string; a word semantically associate with the last constituent of the idiom string; and two unrelated words. The results showed that patients' performance was impaired with respect to a group of matched controls, with patients showing a frontal and/or temporal lesion being the most impaired. A significant number of semantically associate errors were produced, suggesting an impairment of inhibition mechanisms and/or of recognition/activation of the idiomatic meaning.
