Chapter 8 Language and Thought
The Cognitive Revolution • 19th Century focus on the mind • Introspection • Behaviorist focus on overt responses • arguments regarding incomplete picture of human functioning • Empirical study of cognition – 1956 conference • Simon and Newell – problem solving • Chomsky – new model of language • Miller – memory
Language: Turning Thoughts into Words • Properties of Language • Symbolic • Semantic • Generative • Structured
The Hierarchical Structure of Language • Phonemes = smallest speech units • 100 possible, English – about 40 • Morphemes = smallest unit of meaning • 50,000 in English, root words, prefixes, suffixes • Semantics = meaning of words and word combinations • Objects and actions to which words refer • Syntax = a system of rules for arranging words into sentences • Different rules for different languages
Language Development: Milestones • Initial vocalizations similar across languages • Crying, cooing, babbling • 6 months – babbling sounds begin to resemble surrounding language • 1 year – first word • similar cross-culturally – words for parents • receptive vs. expressive language
Language Development:Milestones Continued • 18-24 months – vocabulary spurt • fast mapping • over and underextensions • End of second year – combine words • Telegraphic speech • Mean Length of Utterance (MLU) • End of third year – complex ideas, plural, past tense • Overregularization
Bilingualism:Learning More Than One Language • Research findings: • Smaller vocabularies in one language, combined vocabularies average • Higher scores for middle-class bilingual subjects on cognitive flexibility, analytical reasoning, selective attention, and metalinguistic awareness • Slight disadvantage in terms of language processing speed • 2nd languages more easily acquired early in life • Greater acculturation facilitates acquisition
