o Causes for Forgetting: Decay/Lack of use: Loss due to passage of time without use. Memories will deteriorate on their own as things do in nature. Evidence: probability of forgetting words: infrequently used proper nouns disappear first in our memory. Next come common nouns, then adjectives, then verbs, and lastly, exclamations and interjections. Episodic memory is full of holes. Forgetting occurs more with episodic memory than with semantic memory. Interference: loss due to other material Learning or experiencing one thing can make it less likely for you to remember something before or after it occurred. Proactive Interference: forward acting; older memories prevent new facts from being committed to memory effectively. Retroactive interference: backward acting; new memories tend to replace older ones. Amnesia: severe loss due to trauma or drugs Anterograde amnesia: learning deficit, but memory span (STM) usually normal o You cannot put things into the memory after trauma. You can remember past events, but not future. Korsakoff Syndrome: profound amnesia associated with chronic alcohol abuse. Drug-induced: temporary anterograde amnesia. Surgical and Brain trauma patients: a patient named H.M had his hippocampus removed and he therefore could not remember anything he had experienced. HE could learn new things. Retrograde Amnesia: o Lost of memory of events for a limited period prior to incident (temporal gradient), but information is often retained immediately after incident onwards. Causes include ECS (shock therapy) and head trauma. Problem: memory consolidation and/or retrieval deficit. Recall and Recollection o If you do not understand something, you are likely to not remember it. Example: paragraph in class. The group without the hint had no idea what the paragraph was about and therefore could not remember it. Those with the hint knew it was about laundry and could remember the paragraph rather well.
