From this article, which first describes the progress in grounded cognition theories, then goes into how this should be applied to robotics and artificial intelligence. Some excepts:
"Grounded
theories assume that there is no central module for cognition.
According to this view, all cognitive phenomena, including those
considered the province of amodal cognition such as reasoning, numeric,
and language processing, are ultimately grounded in (and emerge from) a
variety of bodily, affective, perceptual, and motor processes. The
development and expression of cognition is constrained by the embodiment
of cognitive agents and various contextual factors (physical and
social) in which they are immersed. The grounded framework has received
numerous empirical confirmations. Still, there are very few explicit
computational models that implement grounding in sensory, motor and
affective processes as intrinsic to cognition, and demonstrate that
grounded theories can mechanistically implement higher cognitive
abilities. We propose a new alliance between grounded cognition and
computational modeling toward a novel multidisciplinary enterprise:
Computational Grounded Cognition. We clarify the defining features of
this novel approach and emphasize the importance of using the
methodology of Cognitive Robotics, which permits simultaneous
consideration of multiple aspects of grounding, embodiment, and
situatedness, showing how they constrain the development and expression
of cognition."
"According
to grounded theories, cognition is supported by modal representations
and associated mechanisms for their processing (e.g., situated
simulations), rather than amodal representations, transductions, and
abstract rule systems. Recent computational models of sensory processing
can be used to study the grounding of internal representations in
sensorimotor modalities; for example, generative models show that useful
representations can self-organize through unsupervised learning
(Hinton, 2007). However, modalities are usually not isolated but form
integrated and multimodal assemblies, plausibly in association areas or
'convergence zones'" (Damasio, 1989; Simmons and Barsalou, 2003).
"An
important challenge is explaining how abstract concepts and symbolic
capabilities can be constructed from grounded categorical
representations, situated simulations and embodied processes. It has
been suggested that abstract concepts could be based principally on
interoceptive, meta-cognitive and affective states (Barsalou, 2008) and
that selective attention and categorical memory integration are
essential for creating a symbolic system" (Barsalou, 2003).
