Frith has published more than 500 papers[9] in peer reviewed journals, of which about 150 papers have more than 400 citations.[9] He has an h-index of 225.[9] He is the author of The Cognitive Neuropsychology of Schizophrenia (1992), revised and re-issued (2015),[10] which won the British Psychological Society Book Award[11] in 1996.[12] He also wrote the popular science book Making up the Mind: How the Brain Creates Our Mental World (2007),[13] which was on the long list for the Royal Society Prizes for Science Books in 2008 and he co-authored the graphic novel Two Heads: Where Two Neuroscientists Explore How Our Brains Work with Other Brains[14] in 2022.
In 1975 Frith joined an MRC research group at Northwick Park Hospital, dedicated to exploring the biological basis of schizophrenia.[15] There he developed his cognitive account of the symptoms of schizophrenia, in particular delusions of alien control, the false belief that one's actions are being controlled by external forces.[16] Using a predictive coding framework, Frith suggested that, whenever we move, the brain generates predictions about sensory input and that the similarity of these predictions with actual sensory input underpins our sense of agency.[16] Disruption of this process in schizophrenia may lead individuals to attribute their own actions to external sources.[17] This idea continues to be explored by Frith and others[18] and has generated interest among philosophers[19] and artists.[20]
In collaboration with Uta Frith, Chris Frith has promoted the study of social cognition[26] which has become a mainstream interest in neuropsychology.[27] In 2007 he started a collaboration on interacting minds with Andreas Roepstorff [28] and colleagues at Aarhus University, Denmark. Frith and these colleagues demonstrated, experimentally, some of the mechanisms of advantageous group decision making and the emergence of mutual behavioural adaptation in simple joint action.[29] This former work provided the basis for an animation on group decision-making commissioned by the Royal Society.[30] The interacting minds perspective adopted by Frith and colleagues emphasizes the idea that cognition and social interaction are fundamentally intertwined and that the human mind is shaped, not only by a person’s cognitive abilities, but also by their interactions with other minds.[31]
In September 2008, a two day festschrift was held in honour of Frith at the Royal Society.[39] The topic was 'Mind in the Brain'. Hosts included Ray Dolan, Paul Burgess, Jon Driver and Geraint Rees. In 2009 he was awarded the Fyssen Foundation Prize for his work on neuropsychology[40] and he and Uta Frith were awarded the European Latsis Prize for their work linking the human mind and the human brain.[41] In 2014, he and Uta Frith were awarded the Jean Nicod Prize[42] for their work on social cognition. In 2021 he gave the 49th Sir Frederic Bartlett Lecture on the topic "Consciousness, (meta)Cognition, Culture".[43]
