Psycholinguistics

1. Psycholinguistics
Psycholinguistics is concerned with
language as a phenomenon of
individual explaining how he
acquires language, explains his
understanding & comprehension &
communication with others.

2. Language areas in Brain

3. Broca and Wernicke
• The language parts of the brain are named
after two 19th century physicians, Paul Broca
and Carl Wernicke.
Broca’s area is located in the left frontal lobe
and is considered responsible for articulated
language.
Wernicke’s area is located in the left temporal
lobe and is considered accountable for
comprehension of sounds and words.

4. • Motor cortex is an area that generally controls
movement of the muscles (for moving hands,
feet, arms, etc.). Close to Broca’s area is the
part of the motor cortex that controls the
articulatory muscles of the face, jaw, tongue
and larynx. Evidence that this area is involved
in the physical articulation of speech.

5. Arcuate Faciculus
• A white matter tract that connects Broca‟s
Area and Wernicke‟s Area through the
Temporal, Parietal and Frontal Lobes. Allows
for coordinated, comprehensible speech.

7. Aphasia
• Aphasia is one kind of language disorder that
results from damage to the parts of the brain that
contain language. Aphasia causes problems in the
ability to perceive, process, or produce language.
• Aphasia is caused by damage to one or more of
the language areas of the brain.
• Damage to the left side of the brain causes
aphasia for most right-handers and about half of
left-handers.
