|
psychomotor Speed
|
the amount of time it takes us to process a signal, prepare a response, and then execute the response.
Researchers believe that it psychomotor speed reflects the integrity of the central nervous system. |
|
|
reaction time
|
the time it takes to respond to a particular stimulus
|
|
|
general slowing hypothesis
|
the increase in reaction time reflects a general decline of information processing speed within the nervous system of the aging individual
|
|
|
age complexity hypothesis
|
Related to the general slowing hypothesis
proposes that through slowing of central processes in the nervous system age differences increase as tasks become more complex |
|
|
Attention
|
most adults are disadvantaged in.
involves the ability to focus on or concentrate on a portion of experience while ignoring other features of experience |
|
|
Theory of attentional resources
|
older adults have less energy available for cognitive operations than do their younger counterparts across a wide domail of tasks
|
|
|
Theory deficit hypothesis
|
suggests that aging reduces the individuals ability to inhibit or ttune out irrelevant information
|
|
|
dual task aka Divided attention
|
an individual is given information from two input sources
|
|
|
sustained attention
|
maintained attention over a prolonged period of time
ie: respond to only the target stimuli |
|
|
context processing deficiency
|
hypothesis of aging and informational processing proposes that aging affects our ability to take the context of information into account when making judgements u situations such as the sustained attention task
|
|
|
working memory
|
the part of the memory that keeps information temporarily available and active, seems to be particularly vulnerable to aging
|
|
|
phonological loop
|
memory store for speech-based information
the info can be rehearsed by repeating the material over and over again such as an address |
|
|
visuospatial scratchpad
|
part of the working memory that records and maintains visual and spatial images
may be used when trying to figure out the shortest route |
|
|
episodic buffer
|
brings information from long term memory to working memory
|
|
|
the central executive
|
responsible for deciding how to allocate cognitive resources
|
|
|
long term memory
|
information that is held for a period of time ranging from several minutes to a lifetime
|
|
|
Episodic Memory
|
memory for episodes or events in your life
|
|
|
Semantic Memory
|
the equivalent of knowledge includes words and definitions of words found in your vocabulary
|
