Week 5 Flashcards
Patterns of change across the lifespan: Sensory abilitiy
Declines as we age: sense of touch, vision, and hearing decreases
Patterns of change across the lifespan: cognitive ability
declines over time
What 3 cognitive abilities decline as we age?
memory, attention, processing speed,
How is the state of language studies
it is not studied enoguh
How are language skills often categorized as 5 things
speaking, listening, reading, writing, non-verbal
Traditionally a lot of studies focus on blank and blank in older adults
focus on reading and comprehension in older adults
What is the problem with reading and comprehension tests
reading something and then asked to explain it- the issue here is that it’s actually relying on memory
Another way of studying language comprehension can include testing both the
the speaker and listener on remembering info
People are sometimes tested talking to ai as well. Whats the issue with this?
People who talk to AI are typically white, rich people and this is not a representative sample
To process something that requires cognitive abilities, and cognitive abilities rely on accurate sensory info acquisition. What happens if sensory data is not acquired?
the cognitive ability will be informed and wont be good
Speech production in older adults: they are worse which looks like what
talk about unrelated topics, overall less efficient speakers
What do comprehension tests show when looking at older and younger participants
older people perform worse, show less comphrehension
When comparing both younger and older people in similar sensory degradation levels what does the data show?
it says that younger and older people score similarly
What does this data indicate
Hints that sensory degradation as we age may be behind lower comprehension scores in older participants
What is transmission deficit theory:
The transmission deficit model suggests that semantic and phonological information is stored in memory and retrieved separately.
The transmission deficit model suggests connections between semantic representations and phonological representations. do what in aging
they are weakened by aging
What data shows that these connections get worse: vocab size increases with age while total usage remains stable, causing what
causing overall reduction in word frequency, and thus leading to reduced activation of nodes and weakening of connections
What is the tip of the tongue:
Knowing something but the word isnt coming out
Tot task:
shown a picture, and the participant either has to say knows, don’t know, or the word is on the tot
What is semantic ambiguity?
Semantic ambiguity is an uncertainty that occurs when a word, phrase or sentence has more than one interpretation.
