Study Notes
Types of Long-Term Memory
- Long-term memory comprises three types: Episodic, Procedural, and Semantic.
Episodic Memory
- Involves recalling personal life events or episodes, akin to a diary.
- Memories are 'time-stamped,' allowing recall of when events occurred.
- Represents a cohesive unit of memory including people, places, and actions.
- Requires conscious effort to access, such as recalling past dentist visits.
Semantic Memory
- Contains general knowledge of the world, encompassing facts and concepts.
- Similar to an encyclopedia or dictionary, including diverse topics like emotions and everyday knowledge.
- Unlike episodic memory, semantic memories lack 'time-stamps' and are more universal.
- Continuously evolving, incorporating new information and concepts.
Procedural Memory
- Memory for skills and actions, functioning without conscious effort or awareness.
- Examples include driving a car or performing a musical piece.
- Skills may be challenging to articulate; one may find it easier to perform than to explain.
Evaluation of Long-Term Memory Types
- Supported by clinical evidence, neuroimaging findings, and real-life applications.
Clinical Evidence
- Case studies of HM and Clive Wearing illustrate impairments in episodic memory due to amnesia.
- Both individuals retained semantic understanding but struggled with recalling personal events.
- Procedural memory remained intact, allowing for tasks like walking or playing instruments.
Neuroimaging Evidence
- Brain scans reveal distinct brain regions for storing different memory types.
- Tulving et al. (1994) found that episodic and semantic memories activate the prefrontal cortex.
- The left prefrontal cortex is linked to semantic recall, while the right is associated with episodic recall.
- Emphasizes the physical reality of memory types within the brain, validated by subsequent studies.
Real-Life Applications
- Understanding memory types helps psychologists enhance individuals' lives.
- Research by Bellville et al. (2006) demonstrated that improvements in episodic memory are possible in older adults with cognitive impairments.
