Multilevel Linguistic Features Constrain Speech Comprehension

    Humans are experts at processing speech, but how this feat is accomplished remains a major open question. We investigated how speech comprehension is determined by seven different linguistic features, ranging from acoustic modulation rate to contextual lexical information. All these features independently impact the comprehension of accelerated speech, with a clear dominance of […]

Communicative Feedback in Language Acquisition

  Children communicate and use language in social interactions from a very young age. They experiment with their developing linguistic knowledge and receive valuable feedback from their interlocutors. We formalize a mechanism for language acquisition, whereby children can improve their linguistic knowledge in conversation by leveraging explicit or implicit signals of communication success or failure. […]

Conceptual alignment in a joint picture-naming task performed with a social robot

To “align” during a conversation means for interlocutors to achieve similar mental representations of the communicative situation. Can conceptual alignement occur when one of the interlocutors is a robot? Twenty-four French native speakers took turns with a robot in naming images of objects belonging to different semantic categories. For a subset of those semantic categories, […]

MIA: An open-source toolbox for Multi-patient Intracranial EEG Analysis

Intracranial EEG (iEEG) performed during the pre-surgical evaluation of refractory epilepsy provides a great opportunity to investigate the neurophysiology of human cognitive functions with exceptional spatial and temporal precisions. A difficulty of the iEEG approach for cognitive neuroscience, however, is the potential variability across patients in the anatomical location of implantations and in the functional […]

Cross-linguistic gender effects in novice L2 learners

French speakers learned a limited vocabulary in Brazilian Portuguese via computerized games. Learned nouns either shared gender across languages or not. Pre-training, no ERP differences were found in a cross-modal match-mismatch task for match vs. mismatch trials. Post-training, an N400 effect was found for mismatch trials, but only when the grammatical gender of the learned […]

Hippocampal and auditory contributions to speech segmentation

We used frequency-tagging analysis to quantify the neuronal synchronization between the hippocampus and auditory regions, on the one hand, and the temporal structure of words and syllables of an artificial speech stream, on the other hand (A). Intracranial recordings in the hippocampus and auditory cortex (B) show that auditory regions are highly responsive to syllable […]
