Flashcards in File 9.0-9.2: Psycholinguistics (F) Deck (43)
the study of the acquisition, storage, comprehension, and production of language.
The study of language and the physical brain.
The 5 lobes
Temporal lobe, frontal lobe, parietal lobe, occipital lobe, cerebellum
Is associated with perception and recognition of auditory stimuli.
Higher thinking and language production
Many aspects of vision
Least involved with language perception and production.
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
A membrane covering the brain, it is thought that the cortex makes humans able to use language or math.
Where are the language centers contained?
Most are contained in the cortex
What are the different language regions?
- Inferior frontal gyrus (IFG)
- Superior temporal gyrus (STG)
- Sylvian parietotemporal area (SPT)
- Middle and inferior temporal gyri (MTG/ITG)
(See figure page 599)
What are the bumps and indentations on the cortex called?
Bumps are called gyri (or gyrus singular) and the indentations are called fissures.
The Sylvian Fissure
separates the frontal lobe from the temporal lobe
Early processing of sounds is done here in both the left and right hemisphere in the superior temporal gyrus
Middle and inferior temporal gyri
The processing of word meaning and conceptual representations happens here
Sylvian parietotemporal area
is involved in converting auditory and phonological representations into articulatory-motor (sometimes grouped with the posterior STG and called Wernicke’s area)
Sylvian parietotemporal area grouped with the posterior STG is called Wernicke’s area
Inferior frontal gyrus/broca's area
organizing the articulatory patterns of language and directing the motor cortex, which controls movement, when we want to talk. Broca’s area also seems to control the use of inflectional morphemes, like the plural and past tense markers, and function words, like determiners and prepositions
This area, located between the SPT/Wernicke’s area and the visual cortex, converts visual stimuli into linguistic stimuli (and vice versa). The angular gyrus allows us to match the spoken form of a word with the object it describes, as well as with the written form of the word
Area of the brain located in the posterior occipital lobe of each hemisphere; responsible for receiving and interpreting visual stimuli
pathways that are composed of bundles of nerve cells
Path between STG and SPG, phonetic information (broca's)
connecting the STG and MTG/ITG with the IFG runs instead via the extreme capsule
interprets information received from arcuate fasciculus; transmits articulatory information to motor cortex
activated when accessing the lexicon; interprets lexical entry
directs movement of muscles for articulation
each of the brain’s hemispheres is responsible for different cognitive functions
The ability of the brain to adapt to damage and retrain regions
the right side of the body is controlled by the left hemisphere, while the left side of the body is controlled by the right hemisphere
Unable to perceive or produce fluent language
