COGNITIVE CHANGES IN AGING
Agenda
Analyze and evaluate conclusive information about changes in cognitive aging.
Differentiate between cognitive changes that may occur, changes that are stable and changes that may improve during aging.
Evaluate change in cognitive aging to determine if mental functioning can improve in the cognitive
process.
Life Changes in Aging
- NCBI – National Center for Biotechnology Information
- Cognitive aging differs from disease
- Speed of information processing
- Attention
- Memory
- Executive function
- Reasoning abilities
- Intelligence

Cognitive Aging Effects
What does this all mean for working memory and training?
My advice: If you like brain games because they are fun then go for it. But, don’t expect large changes in thinking ability beyond the game.
- WM is quite stable, but it can be modified
- WM training improves WM in the short term
- Sometimes training can produce transfer to attention and memory
- But, its effects are limited and maybe short lived
- But, clearly more research is needed
Can Working Memory be Trained? (RICHMOND, MORRISON, CHEIN, AND OLSON, 2011)
- Assessed if practicing WM tasks can improve performance on those tasks.
- Assessed whether training WM can cause transfer to other tasks.
- Near transfer: Other WM tasks that they did not practice
- Far transfer: Reasoning/attention and memory

What is Cognitive Aging
Jane Scenario
The Scaffolding Theory of Aging & Cognition
- Cognition refers to the mental functions involved in attention, thinking, understanding, learning, remembering, solving problems and making decisions.
- When memory or thinking changes takes a little longer to complete tasks
- Short-Term Memory – Hold items for short periods
- Long-Term Memory – Store unlimited amounts of information
- Driving – Perception and reaction time
