Psychological nominalism
Psychological nominalism is the view advanced in Wilfrid Sellars' 1956 paper "Empiricism and Philosophy of Mind" (EPM) that explains psychological concepts in terms of public language use. Sellars describes psychological nominalism as the view that “all awareness of sorts, resemblances, facts, etc., in short, all awareness…is a linguistic affair.” Judging solely from the mention in EPM, psychological nominalism would seem to be a form of verbal behaviorism, which holds that ascriptions of psychological states are definitionally equivalent to predictions about behavior.
