Clark is one of the founding members of the CONTACT collaborative research project whose aim is to investigate the role environment plays in shaping the nature of conscious experience.
In contrast to traditional models of cognition, which often posit the one-way flow of sensory information from the periphery towards more remote areas of the brain, Clark has suggested a two-way "cascade of cortical processing" underlying perception, action, and learning.
To this, he adds that "personal, affective, and hedonic" factors would be implicated along with the minimization of prediction error, creating a more nuanced model for the relationship between action and perception.
[4] According to Clark, the computational model, which forms the philosophical foundation of artificial intelligence, engenders several intractable problems.
We tend to be susceptible to "grand illusion", where our impressions of a richly detailed world obscure a reality of minimal environmental information and quick action.
Clark's writings also focus on the concept of transhumanism, most prevalent in his work, Natural-Born Cyborgs which explores the progressing incorporation of human biology and technological implants.
