There exists broad agreement that participatory, intersubjective engagements in infancy and early childhood, particularly triadic engagements, pave the way for the folk psychological capacities that emerge in middle childhood. There is little agreement, however, about the extent to which early participatory engagements are cognitively prerequisite to the later capacities; and there remain serious questions about exactly how narrative and other language practices can be shown to bridge the gap between early engagements and later abilities, without presupposing the very abilities that they are supposed to account for. A key issue here is the normativity inherent in requesting, proferring and inferring reasons. I point out that normativity is not a property only of linguistic interactions. Normativity and conventionality are also materially instantiated in the artefactual objects that are most frequently implicated in early triadic engagements. The conventional, canonical functions of artefacts may, however, be overlaid in symbolic play by significations rooted in children's experience of blended actual and virtual worlds. Artefactual objects are amplifiers, as well as objects of consciousness. Interwoven with the symbolic forms of language, they co-constitute a specifically human biocultural niche, within and in virtue of which developing human beings become competent folk psychologists

This article focuses on the interweaving of constructive praxis with communication inontogenesis, inphylogenesisand in biocultural niche evolution (ecogenesis), within anEvoDevoSocioframework. I begin by discussing the nature of symbolization, its evolution from communicative signaling and its elaboration into semantic systems. I distinguish between thesymbol-readyand thelanguage-readybrain, leading to a discussion of linguistic conceptualization and itsdual groundingin organism and language system. There follows an outline account of the interpenetration in the human biocultural niche-complex ofsemiosphereandtechnosphere,mediated by the evolution of the niche of infancy. Symbolization (the foundation of the semiosphere) is by definition normative; the normative character of the technosphere is demonstrated by the interrelations in human development between affordance, action schema and canonical functional object schema. A model of the neuro-computational implementation of dual grounding is proposed.

We present a new road map for research on “How the Brain Got Language” that adopts an EvoDevoSocio perspective and highlights comparative neuroprimatology – the comparative study of brain, behavior and communication in extant monkeys and great apes – as providing a key grounding for hypotheses on the last common ancestor of humans and monkeys and chimpanzees and the processes which guided the evolution LCA-m → LCA-c → protohumans → H. sapiens. Such research constrains and is constrained by analysis of the subsequent, primarily cultural, evolution of H. sapiens which yielded cultures involving the rich use of language.

The biological and neurological capacity to symbolize, and the products of behavioral, cognitive, sociocultural, linguistic, and technological uses of symbols (symbolism), are fundamental to every aspect of human life. The Oxford Handbook of Human Symbolic Evolution explores the origins of our characteristically human abilities - our ability to speak, create images, play music, and read and write. The book investigates how symbolization evolved in human evolution and how symbolism is expressed across the various areas of human life. The field is intrinsically interdisciplinary - considering findings from fossil studies, scientific research from primatology, developmental psychology, and of course linguistics. Written by world leading experts, thirty-eight topical chapters are grouped into six thematic parts that respectively focus on epistemological, psychological, anthropological, ethological, linguistic, and social-technological aspects of human symbolic evolution. The handbook presents an in-depth but comprehensive and interdisciplinary overview of the of the state of the art in the science of human symbolic evolution. This work will be of interest to academics and students active in all fields contributing to the study of human evolution.
