Presentation Transcript

  1. Speech and Language

  2. What to Learn More About Language Acquistion? • Steven Pinker is a professor at Harvard who is a Pulitzer Prize Finalist for his books “How the Mind Works” and “The Stuff of Thought”

  3. Theories on Language Acquisition • 1. Nativism: born with all the words and related morphology, syntax, and phonology that we will ever acquire • 2. Generativism: born with the three, basic concepts but acquire words from experience • chunking • 3. Motherese: learn words and the three, basic concepts from parents

  4. Brain Control of Speech and Language

  5. Temporal and Occipital Lobes + Primary Motor and Sensory

  6. Hemispheric Localization • Language and speech centers primarily located in the left hemisphere

  7. Neuroanatomical Hypothesis For This Hemispheric “Imbalance”

  8. Conservation of Speech and Language Across Species

  9. Damage to These Neural Centers Results in Aphasias

  10. Examples of Broca’s vs. Wernicke’s Aphasia • Broca’s: “O, yea. Det’s a boy an’ a girl..an’…a…car….house..lightpo’….dog an’ a….boat. Ndet’s a ….mm..a…cofee, an’ reading. Det’sa…mm….a…det’s a boy fishin’” • Wernicke’s: “Ah, yes, it’s, ah…several things. It’s a girl….uncurl…on a boat. A dog…is another dog…long’s…on a boat. The lady, it’s a young lady. This…a tree! A boat. No, over in here…a cake….

  11. Neural Map of These Aphasias

  12. Even Deaf Individuals Can Have Aphasias

  13. Three Components of Speech and Language • 1. Morphology: rules for combining words to form bigger words • e.g.: handi+cap vs. handi+cap+able • 2. Syntax: rules for combining words to form sentences and phrases • e.g.: nouns+verb+directobject+indirect object • 3. Phonology: rules for combining sounds to produce words, phrases, and sentences
