Psycholinguistics and Neurolinguistics Psycholinguistics: study of language acquisition, storage, comprehension and production Neurolinguistics: study of the neural and electrochemical bases of language development and use
Psycholinguistics and Neurolinguistics • Psycholinguistics: study of language acquisition, storage, comprehension, and production • Neurolinguistics: study of the neural and electrochemical bases of language development and use
Brain Architecture Right and left hemispheres Hemispheres are connected by the corpus callosum Brain is covered by a membrane called the cortex Bumps on the brain are called gyri, depressions are fissures
Brain Architecture • Right and left hemispheres • Hemispheres are connected by the corpus callosum • Brain is covered by a membrane called the cortex • Bumps on the brain are called gyri, depressions are fissures
Cortex areas o Auditory cortex: receives and identifies auditory signals; Converts them into forms understandable by other areas of the brain Visual cortex: receives and interprets visual stimuli Storage site for pictoral images Motor cortex: sends signals to muscles to make them move
Cortex Areas • Auditory cortex: receives and identifies auditory signals; Converts them into forms understandable by other areas of the brain • Visual cortex: receives and interprets visual stimuli; Storage site for pictoral images • Motor cortex: sends signals to muscles to make them move
Primary motor cortex Supramarginal gyrus Brocas area Angular gyrus Primary auditory area Wernicke's area
Language Centers of the brain Broca s area Located at the base of the motor cortex Responsible for organising articulatory patterns OT language Directs the motor cortex when talk is required Controls use of inflectional and function morphemes
Language Centers of the Brain • Broca’s area • Located at the base of the motor cortex • Responsible for organising articulatory patterns of language • Directs the motor cortex when talk is required • Controls use of inflectional and function morphemes
anguage centers of the brain e Wernicke area: o Located near the back of the auditory cortex Responsible for the comprehension of words Selects words when producing language
Language Centers of the Brain • Wernicke’s area: • Located near the back of the auditory cortex • Responsible for the comprehension of words • Selects words when producing language
Language centers of the brain Arcuate Fasciculus Nerve fibers connecting Brocas and Wernicke's areas Allow the two areas to share information o Required for accessing of the mental lexicon
Language Centers of the Brain • Arcuate Fasciculus • Nerve fibers connecting Broca’s and Wernicke’s areas • Allow the two areas to share information • Required for accessing of the ‘mental lexicon’
Language Centers of the brain Angular Gyrus Located between Wernicke's area and the visual cortex Converts visual stimuli into auditory stimuli and vIce versa Allows matching of spoken and written forms to the objects they describe Crucial for reading and writing
Language Centers of the Brain • Angular Gyrus • Located between Wernicke’s area and the visual cortex • Converts visual stimuli into auditory stimuli and vice versa • Allows matching of spoken and written forms to the objects they describe • Crucial for reading and writing
Language Disorders. Aphasia An inability to perceive, process, or produce language because of physical damage to the brain
