COGNITIONMemory Enhancement in Older Adults
“18”
Cross-sectional Studies: Cohort EffectsTesting people of various
ages at the same point in time using standardized tests
Standardized Testing
Longitudinal StudiesThe same people are studied over a span of time
Intelligence Types
1. Fluid intelligence information processing and memory
2. Crystallized intelligence information people have learned through experience and that they can apply in problem-solving situations
Fluid vs Crystallized Development
Cognitive Decline and Aging
Normal Aging is associated with progressive functional losses in Perception Cognition Memory
Age-Related Cognitive Decline (ARCD)
Non-pathological losses in cognitive function
Nearly universal aspect of aging
Negatively impacts quality of life
May begin as early as 30 Tends to slowly worsen
steadily with age
Brain Plasticity
The brain’s lifelong capacity for physical and functional change
Enables experience to induce learning throughout life
Plasticity Processes
Inherently Competitive
Will always be a “winner” and a “loser”
Plastic changes with negative consequences are just as common as those with positive outcomes
Causes of ARCD
A combination of1. Physical changes in
the aging brain2. Brain plasticity with
negative consequences
Memory Enhancement Study in Healthy Older Adults
“Because the brain retains a lifelong capacity for plasticity and adaptive reorganization, dimensions of negative reorganization should be at least partially reversible through the use of an appropriately designed training program”
Brain Plasticity Research Study
The adult brain is adaptive at any age has a lifelong capacity
to refine the spacial or temporal features of sensory inputs or of movements

Discussion Questions
1. Can increases in crystallized intelligence compensate partially or fully for declines in fluid intelligence in older adults?
Discussion Questions
2. What types of activities can people do to maintain or increase intelligence in adulthood?
