#Speech comprehension relies on prediction, but does the #brain prioritize expected or unexpected info? @fabianschneider.bsky.social & @helenblank.bsky.social show that sharpening of #SensoryRepresentations & #PredictionError processes co-exist at different levels @plosbiology.org 🧪 plos.io/49kkNs0
Paradigm and behaviour. Left: Stimuli. Sixty word pairs were created (e.g., sea-tea) where words within a pair sounded similar and could each be associated with one of six semantic contexts (e.g., sea-tea corresponding to nature-food). To decrease clarity and to induce ambiguity, words were slightly degraded to sound like a whisper and morphed into an intermediate acoustic signal between two words from two different contexts. Morphs were validated in a separate validation experiment (see Stimulus creation). Right: EEG part one with morphed words. Trials began with a fixation cross, followed by a visual speaker cue. Morphs were presented binaurally. Participants then indicated the word they had heard by button press. Finally, feedback was given in a speaker-specific manner such that each speaker could be associated with one specific semantic context. Faces were generated using FaceGen.

A year ago I wrote that meta-RL captures #MedialPrefrontalCortex processing of #predictionerror, #DecisionMaking, and #CognitiveControl. I was wrong. It also captures #Foraging and #WorkingMemory. Thanks to all the authors.

Meta-Reinforcement Learning reconciles surprise, value, and control in the anterior cingulate cortex
Author summary An important debate in cognitive neuroscience concerns the neural basis of cognitive control and the role of the anterior cingulate cortex (ACC). None of the current theoretical framewo...
