Current evidence suggests that cognition-based interventions do improve mental performance (i.e. memory, executive function, attention, and speed) in older adults and people with mild cognitive impairment. [22] Especially, immediate and delayed verbal recall resulted in higher performance gains from memory training.
Primary mental abilities are independent groups of factors that contribute to intelligent behavior and include word fluency, verbal comprehension, spatial visualization, number facility, associative memory, reasoning, and perceptual speed. [145] Primary mental abilities decline around the age of 60 and may interfere with life functioning. [146]
