Document Summary
Studies about the location of a target. Older adults are less accurate in locating the target compared to younger adults. If individuals have damage to the hippocampus, then they show impairments in both spatial and episodic memory. Conducted a study comparing younger (24. 8 years old) and older adults (65. 9 years old) on memory tasks and exapkinign their brain waves. They found differences on the brain waves of younger and older adults. Rhythmic activity within area such as the hippocampus. Involved in forming new memories and retrieving old memories. Involved in sight, hearing, attention, high-level thinking. Prior research has indicated that brain waves that travel at slower speeds are important for memory, and brain waves that travel at faster speeds are important for attention. Rondina and colleagues found that younger adults howerd more slower brain waves (theta power) and older adults showed more faster brain waves (alpha power) Slower brain waves predicted accuracy in memory.
