Deficits Aphasia: acquired brain damage (e.g. stroke)

that impairs language Modularization Specialization, lateralization Task interference

Cerebral cortex Hemispheres Left brain vs. right brain

Corpus callosum

Contralaterality Specialization Left: analytic tasks Right: pattern recognition

Left handers: less lateralization

Autopsy CAT scans PET scans fMRI imaging MEG scans

Nonfluent Frontal damage Global aphasia: mute Broca’s aphasia: halting, effortful ▪ Dysprosody ▪ Phonemic paraphasias ▪ Telegraphic syntax ▪ Aware of the problem

Fluent Damage behind left cortex Difficulty producing, monitoring Wernicke’s aphasia

Writing: dysgraphia Reading: dyslexia Paragraphia Phonological Surface: can’t do wholistic word

recognition

Loss of grammatical abilities

Memory overload / task interference Lexical access Syntactic ambiguity
