generating the phonological word, and finally retrieving syllabic gestural scores and ‎articulation. To study the mechanisms of word retrieval in lemma selection phase, we ‎compared the three groups of monolingual, semi-bilingual and bilingual learners with ‎respect to their topography and strength of Functional Connectivity (FC) values of the most ‎highlighted pair of activated nodes in the time range of 0-150 ms in different frequency ‎bands (delta, theta, alpha, beta, and. gamma) upon application of the stimuli. We have seen ‎no significant difference between difference frequency bands (p > 0.05) at the most ‎highlighted FC pairs. However, we observed higher gamma values signifying the semantic ‎activation of the word. We could not find any significant difference between the groups in ‎terms of FC values at designated pairs of nodes signifying that different amount of exposure ‎could not affect electrophysiological patterns in the preliminary step of word production.‎
