Document Summary
Lecture 8: perceptual and intellectual aging on old age. Working memory capacity increase in childhood, decrease in old age. Slower processing leads to decline in working memory and executive functioning: reduced reserve capacity: due to loos of brain function, de-differentiation of cognitive processes. Sensory and cognitive abilities become more similar over time. Multiple cause models: no just one cause, but multiple (speed, less reserve capacity, working memory) affect cognitive aging. Based on neuro-physiological degeneration: not just affecting advanced ages, but all ages. Baseline capacity: standardized conditions (everyday activity), no training. Baseline reserve capacity: optimized conditions (well rested, fed), no training. Developmental reserve capacity: maximum performance attainable by training, training does not result in improvement in other aspects other than what it is intended, but some benefit in aspects that were similar. Testing the limits of training-based reserve capacity in old age: These testing limits will affect older adults more than younger.
