Recursion all the way: in Language, Action and Semantic
Association

Abstract. Recursion has been considered to be a unique characteristic of human
language. However, increasing evidence in Neuroscience points to the fact that
a fundamental syntactic mechanism is shared between language and action,
both of which have a hieararchical and compositional organisation; Broca's area
has been suggested as the neural locus of this mechanism. In this talk, we will
present the first formal specification of action with biological bases, the Mini-
malist Grammar of Action. The grammar allows the development of generative
computational models for action in the motor and visuomotor space. Through
the grammar, we present examples of recursion in the action space and how a
generative action perception/execution system may account for the phe-
nomenon. Furthemore, we go a step further, arguing that recursion is not a phe-
nomenon that arises in the language or action space only; it is a phenomenon
that lies in any 'syntactic' activity, in any space that comprises 'merging' of ele-
ments into more and more complex units. We present recursion in the Semantic
Association space (Semantic Memory), through the PRAXICON, the first ever
recursive and referential semantic network. We will demonstrate the importance
of the network in generalisation and reasoning for a number of applications and
discuss the interdisciplinary implications of our argument on recursion.
