Further impairments of cognitive function associated with aging include decreased processing speed and inability to focus. A model proposed to account for altered activation posits that decreased neural efficiency driven by amyloid plaques and decreased dopamine functionality lead to compensatory activation. [ 11 ]
Differences in cognitive aging might be tied to the lack of or reduced access to medical care and, as a result, suffer disproportionately from negative health outcomes. As the global population grows, diversifies, and grays, there is an increasing need to understand these inequities.
Bounded rationality attempts to address assumption points discussed within neoclassical economics theory during the 1950s. This theory assumes that the complex problem, the way in which the problem is presented, all alternative choices, and a utility function, are all provided to decision-makers in advance, [24] where this may not be realistic ...
Normal aging is associated with a decline in various memory abilities in many cognitive tasks; the phenomenon is known as age-related memory impairment (AMI) or age-associated memory impairment (AAMI). The ability to encode new memories of events or facts and working memory shows decline in both cross-sectional and longitudinal studies. [8]
Working memory is among the cognitive functions most sensitive to decline in old age. [ 65 ] [ 66 ] Several explanations for this decline have been offered. One is the processing speed theory of cognitive aging by Tim Salthouse. [ 67 ]
Cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process or different areas of cognition. [1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses. [2]
Behavioral economics was the first subfield to emerge to account for these anomalies by integrating social and cognitive factors in understanding economic decisions. Neuroeconomics adds another layer by using neuroscience and psychology to understand the root of decision-making.
Gerontology (/ ˌ dʒ ɛr ən ˈ t ɒ l ə dʒ i / JERR-ən-TOL-ə-jee) is the study of the social, cultural, psychological, cognitive, and biological aspects of aging.The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων (gérōn), meaning "old man", and -λογία (), meaning "study of".
