Speech and Language


Three components of speech and language

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


Theories on language acquisition

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


What to learn more about language acquistion

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”


Brain control of speech and language

Hemispheric localization

Hemispheric Localization

  • Language and speech centers primarily located in the left hemisphere


Neuroanatomical hypothesis for this hemispheric imbalance

Neuroanatomical Hypothesis For This Hemispheric “Imbalance”


Conservation of speech and language across species

Damage to these neural centers results in aphasias

Examples of broca s vs wernicke s aphasia

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….
