The role of motor-relatedness and priming type in the processing of Dutch derived verbs Sophie De Grauwe1, Kristin Lemhöfer1, Herbert Schriefers1 1Radboud University Nijmegen, Donders Institute for Brain, Cognition and Behaviour, Nijmegen, The Netherlands s.degrauwe@donders.ru.nl To find out whether morphologically complex derived words are decomposed or processed holistically, many studies use either morphological priming (priming between a complex word and its stem) or ‘semantic-morphological’ priming (priming between a complex word and a word semantically related to its stem). We used both types of priming with the same stimuli to find out whether type of priming influences results. In addition, we tested whether verbs of the more ‘concrete’ type, namely motor verbs, are processed differently from non-motor-related verbs. In two visual priming experiments, participants made lexical decisions to Dutch derived particle verbs. Half of these verbs contained a stem with a motor-related meaning, the other half did not. In each condition, half of the verbs were semantically transparent (i.e. semantically related to their stems, e.g., afkoelen ‘cool down’), the other half were opaque (e.g., omspringen ‘deal with’). In Experiment 1, results showed an overall morphological priming effect: particle verbs preceded by their stem were responded to more quickly than those preceded by an unrelated prime, independent of Transparency or Motor-relatedness. With semantic-morphological priming (Experiment 2), however, only transparent motor-related particle verbs were primed by words semantically related to their stem. The results suggest that the morphological priming method may overestimate the degree of morphological decomposition, possibly due to methodspecific processing strategies, and that robust evidence for morphological decomposition of verbs exists in particular for transparent and highly concrete, i.e. motor-related verbs. This finding will be discussed in the context of embodied cognition theory. Keywords: priming, morphology, embodied cognition
