In experimental psycholinguistics, research has focused overwhelmingly on either language comprehension or language production. However, the ultimate goal should be to identify the cognitive mechanisms that occur during the actual use of comprehension and production in everyday life, for example in conversation. Turn-taking (Sacks, Schegloff, & Jefferson, 1974) and action-sequencing (Schegloff, 2007) are essential mechanisms in everyday communication, but have not been studied much yet in the domain of experimental psycholinguistics (but see De Ruiter, Mitterer, & Enfield, 2006; Magyari & De Ruiter, 2012; Roberts, Francis, & Morgan, 2006). CA, on the other hand, has focused extensively on these mechanisms, via observing the behavior of conversationalists. To bring these two research domains closer together, in the present study, we aim to look at the cognitive processes that form the foundations for observable turn-taking and action-sequencing behavior in social interaction. We used electroencephalography (EEG), a method that measures electrical brain activity with a very good time resolution, to address this question. In EEG, experimental control is necessary to identify patterns of brain activity related to specific cognitive processes. Using an interactive quiz paradigm in Dutch, we investigated the processes underlying turn-taking in question-answer sequences, while still exerting enough experimental control over both the presented questions and expected answers. Participants were asked quiz questions by a research assistant while their EEG was measured. These questions were in fact pre-recorded, but participants …
