Document Summary
Vocal folds: within the larynx; vibration = pitch & tone. Thin at birth, thicken at 5 months, not adult-like until 7 years (at 5 months, tend to babble with consonants) Sex differences: start around 6, but no impact until puberty (males" voice cracks due to sexual differences) Useful for language, not so useful for teeth and choking. The trade-off is that we can communicate and that enhances survivability much more (which is much more important) Articulators: tongue, palate, lips, cheeks, alveolar ridge, teeth, etc. Location! (e. g. wernicke"s: localism (which parts produce language?) Dynamic localization of function: holism: cares more about your whole brain and how the parts work together (what are the networks that produce language?) Old-school methods: lesion: missing part = missing function o o. Broca"s area: split-brain: hemispheric function, dichotic listening. Present acoustic information to one of the ears (through headphones) Criticisms of fmri: would never use with infants!!! o o.
