b. 1945
Thomas Roeper is a linguist and philosopher of language at the University of Massachusetts Amherst, known for his foundational contributions to the theory of language acquisition and grammatical learnability. His work engages the poverty of the stimulus argument, examining what grammatical knowledge children cannot derive from primary linguistic data alone, providing empirical and theoretical support for nativist accounts of language. He has influenced both generative linguistics and philosophy of mind through research on recursive grammar and the logical problem of language acquisition.
