Final Report Abstract

The presence of information from multiple sensory modalities during learning, known as learning “enrichment”, benefits learning outcomes in many domains, including voice identity recognition, music training, and foreign language instruction. For example, the learning of auditory foreign language vocabulary paired with one’s own body movements or with pictures enhances memory for that vocabulary compared to auditory-only learning. Mechanisms underlying the benefits of learning enrichment are currently unknown. Our primary goal was to discover key behavioural and neuroscientific principles underlying learning enrichment in the domain of foreign language vocabulary learning. Our hypotheses and experimental approach were driven by the multisensory learning theory, which attributes enrichment benefits to the reactivation of brain areas that process the enrichment during learning, e.g., enrichment with self-performed gestures leads to reactivation of biological movement visual areas and motor cortices. To test the hypotheses derived from the multisensory learning theory we used a multi-methodological neuroscience approach to investigate (i) whether brain regions that are active during learning become reactivated during subsequent vocabulary translation, (ii) the causal relevance of responses in the reactivated areas for learning outcomes, (iii) the time course of this reactivation. Besides the neuroscientific questions, we evaluated whether learning enrichment is also beneficial for vocabulary learning in school settings in different age groups.
