PSY2004 W2 Reading Flashcards
Attention and Memory
What is sensory memory?
Where information is first registered. Brief and almost identical representation of the stimuli that exists in the observable environment. Sensory memory takes in large amounts of information rapidly
What is the information processing model?
uses a computer metaphor to explain how people process stimuli. Info enters the system, transformed [based on a person’s knowledge], coded and stored, temporarily stored in computers buffer, permanently stored in story device and can be retrieved in response to some cue
What is attention ?
composed of separate dimensions serving different function. Tasks usually require more than one attentional function.
How is speed processing affected by age?
Salthouse, 1996: researchers believed decline in speed of processing explained the rest of age-related changes in cognitive functioning.
Evidence (neuroimaging): age-related slowing depends on what adults are being asked to do (e.g., choosing which response to make; Choi & Feng, 2016; Nyberg et al., 2012).
Amount of beta-amyloid protein found in the central nervous system, a bio-marker linked with the possible subsequent development of dementia has been shown to be related to the degree processing speed slows (Jagust, 2016; Rodrigue et al., 2012).
What is inhibitory loss?
adults have reduced processing resources because they have difficulty inhibiting the processing of irrelevant information. Evidence indicates the oldest-old have more task irrelevant thoughts during processing and have trouble keeping them out of their minds.
What is prspective memory?
involves remembering to remember something in the future, such as an action or event. Remembering to pick up one’s children after schools.
Event-based task and tume based task
What are event based tasks?
action is to be performed when a certain external event happens.
What is Tume based task?
show more age differences as long as people used self-geenrated strategies to remember, tend to decline with age.
How does multilingualism affect ageing?
In fact, older adults from 75 to 95 years of age who spoke four languages or more showed the best cognitive state. Neuroscience research on the benefits of bilingualism shows that it plays a large role in protecting older adults from cognitive decline, and that functional connectivity in the parietal-frontal control network is stronger These findings suggest speaking multiple languages might be a protective factor for maintaining our cognitive state as we age.
