Email: isabelle.simoesloureiro@umons.ac.be Semantic knowledge includes knowledge about general culture, language but also about objects. Critical knowledge about objects includes “object function” (i.e. the final goal of an object; e.g. the function of a piano is to play music) and “object manipulation” (i.e. the appropriate specific gestures allowing the correct use of an object; e.g. typing with the fingers). Previous studies have already shown dissociation between Function and Manipulation knowledge in left brain damage patients. The present study aims to investigate the electrophysiological activity in the processing of function and manipulation knowledge. To this aim, in an event-related potential study (ERP), twenty right-handed healthy young adults will be included to perform a lexical decision task (i.e. decide if a word is a real word or a pseudo-word) associated to a semantic priming paradigm. Each target will be associated with three types of prime: one sharing the same function (e.g. piano-violin); another the same gesture of use (e.g. piano-keyboard) and finally an unrelated prime will be included (e.g. piano-ladle). The Stimulus Onset Asynchrony was set at 190 ms: the prime will be presented for 90 ms and will be followed by a 100 ms white screen until the presentation of the target. The behavioral responses (priming effects) as well as the electrical activation (event-related potential) will be recorded. At a behavioral level, we expect a facilitation effect (faster reaction time) in function and manipulation knowledge. At an electrophysiological level, event-related-potentials should show that target words related to prime words elicited reduced N400 relative to unrelated target words. The semantic priming paradigm will be presented as well as the preliminary behavioral and electrophysiological results.
