Memory

Some researchers don’t think that younger people can remember things better than older people but their memory is better because they have a higher definition in their brain. Younger people have a better memory because their eyes shed light better than elder people. Dr. Brandon Ally Ko from Vanderbilt University wanted to find out more on this subject.

He decided to do a test to prove this. They picked out 11 older people and 13 younger people. They called the test the “visual change detection.” They had to look at 2-4 dots that had different colors. They had to memorize them and remember which colors they saw. After a few seconds, they took the dots away from the subject. A couple seconds later, they showed one dot to the subject. The dot could’ve been a color they had in front of them before or it could’ve been a color they hadn’t seen before. They were to recognize which colored dots were ones that they saw right away and which ones were not in the group right away.

Dr. Ko found out that behavior measures (the accuracy of the response) indicated a higher capacity in younger adults than in older adults to memorize things. For both of the groups, the neutral measure of memory capacity was very similar. The results show that younger adults can store items in their brain at a higher resolution that older adults can. Also, younger adults have perceptual implicit memory, which helps them remember objects more vividly than older people.
