Document Summary
Sapiens: support for increased social needs was necessary, may have developed language to maintain large social circles. Language development: stages of development, 0-12 months, 12-18 months, 18-24 months, 24-48 months, has been theorized that language development might recapitulate (emulate) language evolution (holophrase -> pidgin -> creole) Overall findings from animal communication studies: limited range of expression (holophrases, little ability to combine symbols to express novel ideas, always about the here and now, provides support for discontinuity theory. Teaching language to apes: maybe apes can learn language but have never had the opportunity to do so. Idea: find another language modality that is more appropriate. P300: is an erp component that is produced by the brain every time it encounters an unexpected stimulus. The experimentation process: we deduce a hypothesis from the theory, we design and conduct an experiment to test the hypothesis, we do an analysis of the data, we make an interpretation of the results.
