the left hemisphere is dominant
T/F
False
Neither hemisphere is dominant. Neither hemisphere
is competent to analyze data and program a response
alone.
lateralization uniquely human
T/F
False
Lateralization of function is not uniquely human, but
the human brain is the most asymmetrical.
the right hemisphere specializes in
– holistic processing and is visuospatial
processing.
– comprehension and production of speech prosody and
affect etc
the right hemisphere may play a role in...
pragmatics, including the perception and
expression of emotion in language, the ability to
understand figurative language etc
the left hemisphere specializes in...
– language in all modalities, math
calculations
– is dominant for control of speech‐ and
– nonspeech‐related oral movements and for math and
language processing.
– is adept at perceiving rapidly changing sequential
information, such as acoustic characteristics of
phonemes in speech.
Almost all right‐handers and 60% of left‐handers
are right‐hemisphere dominant for language.
T/F
False
left-hemisphere dominant
Left Hemisphere
– Language
– Math
– Logic
Right Hemisphere
– Spatial abilities
– Face recognition
– Visual imagery
– Music
Language development is highly correlated
with...
brain maturation and specialization
Two important aspects of brain maturation
are...
weight and organization
By age ___, the brain has usually reached its
full weight.
12
____, _____, or _____ result in less density and decreased
functioning.
Disease, malnutrition, sensory deprivation
Processing areas often overlap
T/F
True
In general, the ______ and _______ lobes are more
active in both perception and production.
frontal, temporal
The left insula is most active in...
speech production;
important for motor feedback from articulators.
In the 60s and 70s, linguists assumed that language
comprehension and production was
linear
Numbers and locations of activated regions differ
across
individuals, vary with the task, cognitive
demands, competing resource, level of difficulty and
familiarity, etc.
Comprehension consists of
auditory processing and
language decoding and involves many areas of the brain
Auditory processing is concerned with the nature of
incoming auditory signal
decoding considers
representational meaning and the underlying concepts
Auditory signals received in the brainstem are relayed to
Primary auditory cortex (Heschl’s area)
Primary auditory cortex (Heschl’s area)
separate
incoming information, differentiating significant
linguistic information from nonsignificant noise.
Linguistic left frontal lobe for
processing
paralinguistic input to the
right temporal lobe
Wernicke’s area
in the left temporal lobe linguistically analyzing incoming information
angular gyrus and the supramarginal
gyrus
assist in linguistic processing and
integrating visual, auditory, and tactile
information.
Reading
Written input is received in the visual cortex
and transferred to the angular gyrus, where it may be
integrated with auditory input; it is then transmitted to
Wernicke’s area for analysis.
Semantic analysis
is distributed across the brain
frontal lobe directs
the process and evaluates the
information coming from Wernicke’s area where the
semantic processing actually occurs.
storage of word meanings is
diffusely located, centered primarily in the temporal lobe.
Pragmatic analysis involves the
frontal lobe and integration of paralinguistics from the RH.
The message structure is organized in
Wernicke’s area, then the message is transmitted through the arcuate fasciculus
arcuate fasciculus
a white matter tract underlying the angular gyrus, to Broca’s area
Broca’s area is responsible for
detailing and coordinating speech programming.
Signals are passed to regions of the
motor cortex that activate the muscles responsible for respiration, phonation, resonation, and articulation.
Writing follows a similar pathway, passing from
Wernicke’s area to the angular and supramarginal gyri,
then to Exner’s area (motor cortex) for activation of the
muscles used for writing.
there is no relation between intelligence and the speed of information processing
T/F
False
there is a relationship
Effortful processing requires
concentration and attention
Both thought and language are processed by the
brain’s information processing system.
brain’s information processing system includes
cognitive processes involved in attention, perception, organization, memory, concept formation, problem‐solving and transfer, and executive function
Attention
• includes awareness of a learning
situation and active cognitive processing.
• Attend best when motivated
Less mature individuals' attention are
less efficient at attention allocation and have a more limited attentional capacity
Discrimination
• is the ability to identify different stimuli.
• It requires working memory
working memory
•holds the message during processing for language decoding
•important for decoding if spoken language that
the brain can hold the information that is not longer
present (hold sentence during analysis)
Linguistic experience aids memory
T/F
True
Working Memory consists of
several related systems for language processing under the control of a central executive
Organization
• important for later retrieval.
• Memory capacity is likely fixed and better memory results from
better organization.
Memory
• organism's ability to store, retain, and recall
information and experiences
• Information is moved to more permanent storage via short‐term
memory.
. Short]term memory (old term. New term: working memory)
Short‐term memory (old term. New term: working memory)
– limited capacity (only about 7 items can be stored at a time)
– limited duration (storage is very fragile and information can be lost
with distraction or passage of time)
Incoming information is either
discarded or held in working
memory and rehearsed for more durable long‐term memory
Information is retained in long term memory by
rehearsal or repetition and organization.
Memory is best when linguistic information is
deep processed, which includes semantic interpretation/elaboration and relating to prior experience/knowledge
Words may be stored in various locations based on
meaning, word class, sound pattern, and categories
Transfer or generalization
- is the ability to apply previously learned material to similar but novel problems
- 2 types of generalization: near transfer and far transfer
near transfer
When the two are very similar, generalization
far transfer
When very dissimilar, generalization
Language processing is limited by
the amount of incoming and stored language data, the demands of the task, and available cognitive resources
overloads decrease
efficiency
Executive function
determines cognitive strategies and activities needed for a task and monitors feedback and outcomes in order to re‐allocate resources
Metacognition (your knowledge of your own cognition
and memory processes), can facilitate
encoding, retrieval and use of problem solving strategies
Theory of Mind (ToM)
• learn that people have thoughts,
beliefs, and feelings that are not the same as
theirs
• requires social and interactional experience
over several years to reach fully mature abilities
The relationship between ToM and language may
be
• dynamic
• Each contributes to the development
of the other.
Language precedes and promotes
ToM development but not vice versa
Language is the necessary precursor to acquire ToM
Language and ToM development are
interdepednent
A two‐way street.
