Kathrin Münsch, Department of Psychology: "Temporal integration of information during speech perception and production"
To understand the world, we must combine patterns of information over time. For example, we effortlessly understand each word within the context of a continuous sentence. Our ability to integrate information over time may however be affected by the meaningfulness of the information we integrate. We recorded electrocorticographic (ECoG) signals from four participants who perceived, silently rehearsed and reproduced spoken sentences. Across trials, the meaning of identical sentences was manipulated via a prior contextual cue. In addition, meaningless sentences were used as a control condition. We present preliminary results, focusing on reliable stimulus-locked fluctuations of high-frequency power (70-200 Hz) in auditory and motor regions during speech perception. The current paradigm complements accounts of temporal integration based on verbal working memory, by instead focusing on the role of semantics in the continuous integration of incoming naturalistic information.
