# Traditional Approach to STM and LTM | Feature | STM | LTM | |---|---|---| | Capacity | Limited - 7±2 | Unlimited | | Rate of forgetting | Decays within 20 secs if not rehearsed | Forgetting due to interference rather than decay | | Type of code | Phonological | Semantic | ## Modern version of S...
# Traditional Approach to STM and LTM | Feature | STM | LTM | |---|---|---| | Capacity | Limited - 7±2 | Unlimited | | Rate of forgetting | Decays within 20 secs if not rehearsed | Forgetting due to interference rather than decay | | Type of code | Phonological | Semantic | ## Modern version of Short-term memory: - Working memory - Central executive & episodic buffer - "Slave" systems - Phonological loop - Speed of language can impact this! - Visuo-spatial Scratch pad # 5/8 W2 Lecture 1 ## Long-term memory ### Memory - Declarative memory system - Semantic - Episodic ### Nondeclarative Memory System - Episodic memory: a memory for things that have happened to you (episodes) - Semantic memory: a memory of things. ex: knowing what a word means ### Hierarchical Network Models: Collins & Quillian (1969) - Superset relationships: two main factors - Property relationships - Associational network models: - Different for every human, appears random - Proposition networks - Story-based - Parallel Distributed Processing models (PDP) - Like neural networks (much simpler) - Made by a computer - First model that stereotypes - > what allows us to identify all different types of chairs, etc.
