Study Notes
Dual-Store Model of Human Memory
- Three components: sensory register, working memory, and long-term memory
- Sensory register: receives information through senses, very large capacity, duration less than a second (visual) and 2-3 seconds (auditory). Information is stored in its original form
- Working memory: has limited capacity, information persists for a few seconds unless actively rehearsed. Information is processed through attention to sensory register or through cross-communication with long-term memory
- Long-term memory: virtually boundless capacity, stores information indefinitely
Challenges to the Model
- Three components may not be entirely distinct but more like potentially overlapping mechanisms (e.g., sensory register and working memory).
- Working memory and long-term memory may be aspects of a single mechanism.
- Active processing in working memory may not be absolutely necessary for storage in long-term memory.
- Processing speed and recall of serial lists. Initial and final items are recalled faster than middle ones ("primacy" and "recency" effects)
- Alternative models: single-store, levels-of-processing.
Different Functions and Parts of the Brain
- Different parts of the brain are involved in working memory processing/long-term memory storage
- Difficulty recalling items may be related to problems in the involved area
- Implication of possible problems with storage or retrieval (single store) versus the distinction of separate functioning parts (dual store)
- Certain parts of the brain are specialists in different function.
Memory Storage and Conscious Thought
- Long-term memory may not always require conscious processing
- Some information may be automatically stored
- Non-conscious storage; and unconscious processing aspects.
Alternative Views of Human Memory
- Levels-of-processing model: Incoming information is processed at different levels of complexity by a central processor
- Activation models: emphasize cognitive processes more than structural aspects of memory
