Document Summary
Cognition refers to the mental processes involved in acquiring knowledge. A language consists of symbols that convey meaning, plus rules for combining those symbols, that can be used to generate an infinite variety of messages. Phonemes are the smallest speech units in language that can be distinguished perceptually. Morphemes are the smallest units of meaning in a language. Semantics is the area if language concerned with understanding the meaning of words and word combinations. Connotation is a words emotional overtone and secondary implications. Syntax is a system of rules that specify how words can be arranged into sequences. Fast mapping is the process by which children map a word onto an underlying concept after only one exposure. Overextension occurs when a child incorrectly uses a word to describe a wider set of objects or actions than it is meant to. Underextension occurs when a child uses a word to describe a narrower set of objects than it"s meant to.
