Memory loss

During chapter 7, we talked a lot about short term memory, long term memory, and memory loss. For someone who has a normal memory, their short term lasts for about twenty seconds and can hold five to seven items at a time. For long term memory, it is essentially permanent and can hold an unlimited amount. But, if someone has been in an injury, they can later suffer from memory loss. Depending on the injury, someone can suffer from either retrograde or anterograde amnesia.
My uncle is a perfect example of someone who suffers from anterograde amnesia because he can’t remember events that have occurred after the accident. My uncle is married and has two children. When he was 33 years old, he was in a horrible car accident. Driving down the high way, a truck hit the back side of his car and it caused it to roll over several times. He was unconscious when the police arrived at the scene. Now many years later he suffers from memory loss. He can remember that he is married and knows who his wife is, but he can’t remember what a marriage actually is. If he is retold what it is, he will know for about twenty seconds then forget, and can’t remember. He also knows that he is a father to two wonderful children but he can’t comprehend what a father is and what he is supposed to do. As he observes other fathers and hears his friends talk about their children he can understand what a father is for as long as his short term memory lasts, but will later forget.
