According to recent action-oriented perspectives in cognitive neuroscience, brain mechanisms of cognition and language are built from those for action and action perception (1, 2). Whereas traditional approaches have attributed specifically-human cognitive domains to genetic endowment and encapsulated processes, modern brain science has shown that mechanisms for speech sounds and symbols emerge as a result of sensorimotor functional interaction in the brain. Correlational Hebbian learning in anatomically prestructured network architectures binds articulatory-motor to auditory-perceptual (phonological) knowledge, and explains important aspects of the storage of (lexical) whole forms as symbols or constructions, combinatorial (syntactic, grammatical) linkage between stored forms, and context-dependent flexible (semantic, pragmatic) binding between forms, their meaning and interactive function. Therefore, it becomes possible to ‘spell out language in terms of neurons’. For example, when words become meaningful, their distributed neuronal assemblies link up with other networks processing ‘brain-embodied’ information about objects and actions. Similar learning can also emerge at the level of phrases and whole constructions. In the case of idioms (for example: ‘She grasped the idea’), neuroimaging data suggest that semantic processes take place at the word level at the same time as at the construction level (3). For understanding the communicative function of words and constructions, predictions on future actions and goals are calculated based on linguistic utterances and their action context (for example, the word [ti:] in front of a tea pot may be understood as a request). Neuroscience research has recently shown how communicative function and action prediction is reflected in brain responses, where it engages action systems (4). The new action-centered perspective on language and communication has not only led to a better understanding of the interplay between language, action and cognition, it also carries translational fruit, for example in the context of novel approaches to language rehabilitation after stroke (5).
