Document Summary
If you return to the same se0ng. Can recall be=er if happy during exams. Not only encoding informa;on but all of the context. The cues present during encoding will be used for retrival cues. When people learn informa;on underwater versus on land. List to be learned in water and land. Later asked them either inland or under water to recall the informa;on. Both context and state can be con ated. Mood or physiological states are states that can help to recall informa;on. Depressed individuals more likely to recalls memories. Because they are depressed as adults they remember those. Could also be they are depressed because they had sad childhood. Learning from past will help tp learned informa;on in the future. Learn to play baseball and then tennis. Use baseball skills to try to learn tennis (how to hit) Forget weeks or few years in the past. Forget latest memories rst and earlier memories last.
