This document provides evidence and a learning outcome for Unit 3 of a psycholinguistics course. The evidence asks students to summarize the central neurological system and language process based on a linguistic model in order to compare the cognitive, perceptive, social and communicative development of children's language. The learning outcome is for students to create a mind map about the central neurological system and language process from a linguistic perspective. The reflection identifies that the brain controls motor and sensory activities, has two hemispheres with the left controlling the right side of the body and being specialized for language acquisition.
