Document Summary

Cognition the way the mind works; specifically, the process of attention, memory, intelligence, problem-solving, and the use of language. Processing speed the amount of time it takes for an individual to analyze incoming information from the senses, formulate decisions, and then prepare a response on the basis of that analysis. Reaction time basic measure of processing speed. Simple reaction time tasks participants are instructed to make a response like pushing the key as soon as they see the target. Choice reaction time participants must make one response from one stimulus and another response for a different stimulus. General slowing hypothesis the increase in reaction time reflects a general decline in information processing speed with the ns of the aging individual. Age-complexity hypothesis proposes that through slowing of central processes in the. Ns, age differences increase as tasks become more complex and the older adult"s processing resources are stretched more and more to their limit.
