7 Cognition and Categorization

Last week, we explored some important concepts related to the lexicon and some cognitive processes determining them.

Lexical structures

• Lexeme: set of inflectional forms that are related via their meaning
• Lemma: all inflectional forms of a lexeme
• Lexicon: system of lexemes
• Lexical field: class of lexemes with common meaning and co-occurrence patterns

Cognitive concepts

• Association: emergent networks in memory
• Contiguity: spatial and temporal correlation
• Salience: distinctiveness
