To view language as a cultural tool challenges much of what claims to be linguistic science while opening up a new people-centred linguistics. On this view, how we speak, think and act depends on, not just brains (or minds), but also cultural traditions. Yet, Everett is conservative: like others trained in distributional analysis, he reifies ‘words’. Though rejecting inner languages and grammatical universals, he ascribes mental reality to a lexicon. Reliant as he is on transcriptions, he takes the cognitivist view that brains represent word-forms. By contrast, in radical embodied cognitive theory, bodily dynamics themselves act as cues to meaning. Linguistic exostructures resemble tools that constrain how people concert acting-perceiving bodies. The result is unending renewal of verbal structures: like artefacts and institutions, they function to sustain a species-specific cultural ecology. As Ross (2007) argues, ecological extensions make human cognition hypersocial. When we link verbal patterns with lived experience, we communicate and cognise by fitting action/perception to cultural practices that anchor human meaning making.

Recent evidence implicates both basal ganglia and ventrolateral prefrontal cortex (vlPFC) in encoding value memories. However, comparative roles of cortical and basal nodes in value memory are not well understood. Here, single-unit recordings in vlPFC and substantia nigra reticulata (SNr), within macaque monkeys, revealed a larger value signal in SNr that was nevertheless correlated with and had a comparable onset to the vlPFC value signal. The value signal was maintained for many objects (>90) many weeks after reward learning and was resistant to extinction in both regions and to repetition suppression in vlPFC. Both regions showed comparable granularity in encoding expected value and value uncertainty, which was paralleled by enhanced gaze bias during free viewing. The value signal dynamics in SNr could be predicted by combining responses of vlPFC neurons according to their value preferences consistent with a scheme in which cortical neurons reached SNr via direct and indirect pathways.
