| Beschreibung: | The semantic memory system contains the knowledge we acquire through experience in form of highly integrative conceptual representa-tions. These are fundamental for higher cognitive functions such as language. In how far conceptual processing recruits the same brain areas, which were involved during the initial experience with the concept’s referent is a matter of ongoing debate. The most recent theoretical approaches assume experience-specific brain areas and higher order semantic hubs to interact hierarchically. The studies presented in this dissertation investigated the role of experience in processing recently formed object representations as well as of consolidated abstract mathematical concepts. The first three studies employed a training paradigm to examine experience-dependent processing of the names of novel objects. These studies suggest that processing the novel objects representations recruits the same brain areas involved in the experience gained during a short training period. In Study 4, accumulated mathematical experience specifically affected the processing of mathematical words. This study supports the generalizability of experience-dependent semantic processes from concrete to abstract knowledge. Altogether, the current findings provide evidence for an experience-dependent formation and processing of conceptual representations. Importantly, the presented results reflect conceptual processing untainted of any perceptual influences, as we accessed the conceptual representation via lexical stimuli. This dissertation delivers important insights into the dynamics of conceptual processing at different stages of consolidation as well as across concrete and abstract knowledge, contributing to a comprehensive understanding of semantic memory. | |||||||
