Abstract The production of words, a faculty that characterizes humans, is influenced by several factors depending on the speaker himself, or related to the characteristics of the produced words. Among these factors, the speaker age plays an important role on the performance in words selection and production; similarly, (psycho-)linguistic factors like the frequency of the word, its length, its semantic category, etc. are to be taken account to. The characteristics of the lexical-semantic network, proper to each word, have also been shown to impact the word production. However, the lexical-semantic network itself has different characteristics associated to the speaker age. The main findings of the current thesis confirmed that both the lifespan differences in performance, and the neurophysiological correlates underlying word production are influenced by the richness and prototypicality of the age-specific lexical-semantic network of the speaker.
