PSYCH 101 Lecture Notes - Lecture 31: Prospective Memory, Decay Theory, Interference Theory
Document Summary
Hermann ebbinghaus: measured memory by using relearning and computing a savings percentage, tested himself on forgetting by reading so many lists. Forgetting curve: forgetting occurs more rapidly at first, and then more slowly as time passed. Fail to encode deeply b/c we turn our attention to something else. Decay theory: with time and disuse the physical memory trace in the nervous system fads away (can"t be identified) Reminiscence: when participants learn a list of words or a set of visual patterns and are retested at two different times, they sometimes recall more material during the second testing than during the first. Tip-of-the-tongue phenomenon (tot): we cannot recall a target word but feel that we"re on the verge of recalling it. Repression: protect us by blocking the recall of anxiety-arousing memories. Retrograde amnesia: represents memory loss for events that occurred prior to the onset of amnesia.
