This document provides guidance for answering the question "What is language?" by discussing two perspectives: experimental psychology and discursive psychology. Experimental psychology views language as the topic to be studied through experimentation, focusing on relationships between language and cognition. Discursive psychology sees language as performative and studies how topics are constructed within discourse rather than psychological processes. The document instructs the student to critically evaluate the differences in how each approach thinks about and studies language, using examples from cognitive, developmental, and social psychology, to convey both perspectives for their essay.
