PHE102 Lecture Notes - Lecture 3: Anterograde Amnesia, Retrograde Amnesia, Psychogenic Amnesia
Document Summary
Whether we store and can retrieve information is impacted by whether we encode it in to our ltm through repetition or rehearsal and whether the information is meaningful to the individual. People may forget due to decay (not rehearsing the info), displacement (new memories replacing the old ones) and interference (distortion due to similar information already being in memory). Retrograde amnesia - the loss of pre-existing memories.

People with dementia usually lose more recent memories first and keep older memories longer. Anoxia: a depletion of oxygen levels can also affect your entire brain and lead to memory loss. If the a(cid:374)o(cid:454)ia is(cid:374)(cid:859)t severe enough to cause brain damage, the memory loss can be temporary. Damage to the hippocampus: when your hippocampus is impaired, you will have difficulty forming new memories.
