Producing language in different modalities
With this line of research we aim at gaining a deeper understanding on the temporal course of lexical selection in speech production. Specifically, whether lexical selection occurs in a fixed time-window during speech production or if on the contrary is affected by the production task at hand.
We will do it by comparing the electrophysiological correlates associated to lexical selection in speech production with other types of production such as typewriting/handwriting or other production modalities as the signed language.
By comparing speech and writing we will investigate how the temporal course of lexical selection is influenced by processes occurring later in production (e.g., the conversion from phonology to orthography is required only in writing).
By comparing speech and signed production we will investigate how the temporal course lexical selection is influenced by the difficulties in the task, as signing instead of naming. For that we recruited highly proficient signed language interpreters performing the task in both modalities.
