The comprehension of ambiguous idioms in aphasic patients.

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.

Grammatical gender in the brain: evidence from an fMRI study on Italian.

The grammatical gender of a word is a lexical-syntactic property determining agreement among different sentence parts. Recent fMRI investigations identified the areas involved in the retrieval of grammatical gender near the left Broca's area providing further evidence to confirm the preeminent syntactic role of this area. However, these studies employed categorical designs based on the controversial methodology of the cognitive subtraction of neural activations related to different tasks. In the present study we identified the neural substrates of grammatical gender assignment using an fMRI parametric study. Participants decided the grammatical gender of visually presented Italian words whose gender-to-ending regularity varied. The results showed activation in left and right fronto-temporal areas suggesting an interplay of both hemispheres in the processing of grammatical gender.

Reading comprehension and understanding idiomatic expressions: a developmental study.

The aim of the present study was to investigate idiom comprehension in school-age Italian children with different reading comprehension skills. According to our hypothesis, the level of a child's text comprehension skills should predict his/her ability to understand idiomatic meanings. Idiom comprehension in fact requires children to go beyond a simple word-by-word comprehension strategy and to integrate figurative meaning into contextual information. In a preliminary phase, we used a standardized battery of tests (Cornoldi & Colpo, 1998) to assess the ability of second graders and fourth graders to comprehend written texts. Three groups were identified at each age level: good, medium, and poor comprehenders. Children were then presented with familiar idiomatic expressions which also have a literal meaning (e.g., "break the ice"). Idioms were embedded in short stories: in Experiment 1 only the idiomatic interpretation was contextually appropriate, in Experiment 2 a literal reading of the string was also plausible in the context. A multiple-choice task was used in both experiments: children were asked to choose one answer among three corresponding to: (a) the idiomatic meaning; (b) the literal meaning; and (c) an interpretation contextually appropriate but not connected with the idiomatic or literal meaning of the idiom string. The results of both experiments showed that the ability to understand a text indeed predicted children's understanding of idioms in context. To verify whether possible improvements in children's comprehension skills might produce an increase in figurative language understanding, Experiment 3 was carried out. A group of poor comprehenders who participated in Experiments 1 and 2 was tested eight months later. The results of Experiment 3 showed that children whose general comprehension skills improved their performance on an idiom comprehension test.

The creation of new figurative expressions: psycholinguistic evidence in Italian children, adolescents and adults.

According to a developmental model of figurative language acquisition--the global elaboration model (Levorato & Cacciari, 1995)--the metalinguistic awareness necessary to use figurative language in a creative way is acquired late, and is subsequent to the ability to comprehend and produce figurative expressions. One hundred and eight children aged 9;6, one hundred and twenty-four children aged 11;3, one hundred and twelve adolescents aged 18;5 and one hundred adults participated in Experiment 1 which studied the development of metalinguistic awareness through an elicitation task. The subjects produced a high percentage of figurative expressions with a clear developmental trend that is concluded in adolescence. In addition, Experiment 2 showed that the production of comprehensible, appropriate and novel metaphors, as they were rated by adult judges, also increased with age. These results show that the ability to use figurative language in a creative and sensible way requires a long developmental time span and is strictly connected with the ability to reflect on language as a complex cognitive and interpersonal phenomenon.
