This chapter explores the entanglement of cognitive psychology with science fiction, but avoids familiar motifs from post-cyberpunk fiction. The beginnings of cognitive psychology are traced to the foundational work of figures such as George Miller and Noam Chomsky, subsequently codified into a self-conscious school by Ulrich Neisser. Jack Finney’s classic narrative, The Body Snatchers (1955), draws upon earlier proto-cognitivist discourses to contend, often quite didactically, that the human mind typically operates as a biased, limited capacity information processor. With this psychological and political thesis, the novel explores possible personal, political and aesthetic strategies that might free the human mind from its stereotypes and blind spots. The unsettling of everyday perception in The Body Snatchers is systematically generalized by the linguistic novums of Ian Watson’s The Embedding (1973), Samuel Delany’s Babel-17 (1966), and Ted Chiang’s ‘Story of Your Life’ (1998), which imagine that language (and thought) is fundamentally constructive of perceived reality. These stories ask broader, cosmological questions about the nature and accessibility of ultimate reality – with Watson’s novel ultimately proposing a mystical riposte to cognitivism’s model of the mind.
