Final Report Abstract

The SOM project addressed the mechanisms of semantic understanding of sounds and words in and out of sentence contexts at the linguistic experimental level. By comparing behavioral and brain responses to semantically isolated and context-embedded congruent and incongruent, we obtained clues about the neural mechanisms underlying semantic representation. These could be fruitfully applied to validate current theories of semantic processing, in particular the ASS vs APS families of models. Results showed a clear superiority of APS theory. Unexpected was the discovery of a novel brain component which emerged in anticipation of predictable stimuli, the Prediction Potential. This new brain index reveals the subjects’ semantic and pronological predictions before the predicted stimuli actually appear. The observation of systematic functional relationship between the PP and the subsequent brain responses, such as the MMN and the N400, opens a novel avenue for testing theories of predictive coding.
