Chapter 15 Part 2 Flashcards
Aging is related to general ____ of neurons (eg. Reduced brain volume) especially in the ____ lobe and ____ - areas involved in higher cognitive function and memory
Shrinkage; frontal; hippocampus
Aging is associated with loss of ____ (fatty issue surrounding the neurons that normally speeds up neural impylses), ____ in number of connections among neurons and ____ of certain neurotransmitters, and also reduced ____ flow in the brain.
Myelination; reduction; availability; blood
A study by Colcombe et al. (2003) found that ____ is beneficial for improving cognitive function in older adults.
Exercise
Rahhal, May, and Hasher (2002) wanted to know are all sources equally difficult for older adults to remember. What did they find?
With voice source (perceptual info), young adults had significantly more correct responses than older adults, while with character nature (conceptual info), young and old adults did kinds of the same (~75%)
Although older adults show ____ in both item memory and the ability to create new associations, more ____ information may resist age-based declines.
Deficits; Meaningful
Hasher & Zacks (1988) proposed the inhibitory deficit hypothesis of aging, which suggests that…
Older adults have difficulty inhibiting task irrelevant information and tend to go on the dominant response rather than a contextually appropriate response
What were the results of Hasher & Zacks (1988) speed of color naming in the STROOP task and what does it suggest?
When word and color are different, older adults took significantly longer to recognize the color of each word, which demonstrated the inhibitory deficit hypothesis of aging.
Negative stereotypes create expectations of ____ memory in older adults, and can ____ active learning strategy in older adults, which in turn create poor ____.
Poor; discourage; retention
Rahhal, Hasher, and Colcombe (2001) presented trivia statements to young and old participants that had either memory-emphasis or neutral prompts. What did they find?
Performance is only impaired in the older adults when memory is emphasized in the instructions
Older adults have ____ in ____ task irrelevant responses in order to provide a more ____ relevant one. Also, ____ based on aging can have a negative impact on older adult’s memory performance based on how the task is characterized.
Deficits; inhibiting; contextually; stereotypes
Spot-the-word
Find the real word in pairs like “rabbit-flotter”
Speed of comprehension
Verify statements like “Snake crawl along the ground”
In a study by Saxton et al. (2001), while performance of ____ ____ ____ task declined as age increased, performance of ____-____-____ tasks remained unchanged.
Speed of comprehension; spot-the-word
Klooster, Tranel, and Duff (2020)
Klooster, Tranel, and Duff (2020) compared people with amnesia (Amn) with two groups: current age-matched controls (CA) and people of the same age as when amnesia was onset (AoO). What were their results and what did it imply?
The current age matched CA group performed best on semantic memory tasks despite being older, which shows that semantic memory is enriched over time.
