|
|
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. |
