Putting words together in the mind for speech production
This talk will be about how we plan and produce speech. More specifically, how do we put together words and sentences and what are the linguistic units that need to be activated and retrieved from long-term memory. Words can consist of smaller meaningful elements called “morphemes”, e.g. the English compound dishwasher consisting of dish (meaning: ‘dirty dishes’) and washer (derived from ‘to wash’; meaning: ‘to clean’). How do we represent words like dishwasher in our memory – as one holistic entity or do we (also) store the morphemes dish, wash, and the suffix -er separately?
The present series of studies investigated morphological priming as well as its time course and neural correlates in overt speech production using a long-lag priming paradigm. Behavioural (reaction time), event-related potential (ERP), and neuroimaging (fMRI) data were collected in separate sessions. Recently, we extended our research to multilingual participants. I will report about five different studies which show an extremely coherent picture and argue for a separate level of morphological processing in language production planning.
We look forward to seeing you there!
