"A lawyer is a shark". Iconic representation in comprehending frozen metaphors). Paper considered the cognitive and linguistic processes underlying the comprehension of frozen metaphors, by analyzing both neuropsychological and behavioral data. In order to compare the dichotomy between a pragmatic model (i.e. the metaphor as a semantic anomaly) and a direct access model (the metaphor as an ordinary meaning) on one hand, and between an iconic contro not iconic representational modality on the other hand, the paper explored the event-related potentials (ERPs) and the response time (RT) of subjects submitted to verbal stimuli. 36 subjects were required to comprehend metaphorical and literal sentences, half congruous (not anomalous) and half uncongruous (anomalous). The morphological analysis of the EEG profile allowed to observe a negative deflection (the N3 effect), differently distributed on the scalp surface. Repeated measures ANOVA for peak amplitude and latency variables underlined that N3 effect shows an ampler deflection for the metaphoric decoding in comparison to the literal one, increased on the occipital area, likely a marker of a specific iconic representational format. Thus, though not equivalent, the two processes are not differentiated as a function of the way of the meaning access (direct or indirect), nor for the elaboration complexity (RT variation) but for the typology of the representational format, more iconic for metaphoric stimuli, as it was showed by an increased N3 on the occipital area.
