Information Processing Model of Memory

• Introduced by Atkinson and Shiffrin, states that there are three types of memory storage: sensory memory, short-term memory, and long-term memory.

Sensory Memory

• Brief retention of sensory information (like sights and sounds).

• Focused on echoic memory (auditory sensory memory).

• Information that can exceed "seven plus or minus two" when chunked into higher order units (e.g., remembering TV channels).

• Example: Remembering TV stations as categories rather than individual names can help retain information.

Short-Term Memory (STM)

• Retains information temporarily for processing before it moves to long-term memory.

• Often involves rehearsal but cannot maintain information indefinitely.

• Example: Remembering phone numbers by chunking them into meaningful units (like area codes).

Long-Term Memory (LTM)

• Biologically permanent type of memory with an extended duration.

• Divided into explicit (declarative) and implicit (nondeclarative) memories.

Explicit Memory

• Memories that can be consciously recalled and declared.

• Includes:

  • Episodic Memory: Personal experiences and specific events (e.g., your first day at college).

  • Semantic Memory: General facts and knowledge about the world (e.g., names of capitals).

Implicit Memory

• Memories that are not explicitly stated or consciously recalled.

• Involves learned skills and conditioned responses, typically demonstrated through performance rather than recall.

• Classical conditioning examples: A neutral stimulus that gains meaning after being connected to a significant stimulus (e.g., dogs salivating at a bell).

Information Retrieval

• The ability to access stored information depends on effective retrieval cues.

• Example Activity: Reciting words presented earlier demonstrates recall efficiency (e.g., listing words heard during class).

Serial Position Effect

• Primacy Effect: Better memory for the first few items in a list.

• Recency Effect: Better memory for the last items in a list; only strong for immediate recall, fades over time.

• Results of studies show a decline in memory retention over time after initial learning.

Memory Retention Over Time

• Memory retention tends to decline rapidly in the first few hours and stabilizes after a period.

• Example of forgetting a penny's details showcases how familiar objects can be overlooked.

Tips for Improving Memory Retention

1. Find Study Partners: Sharing knowledge can enhance learning.

2. Rehearse: Actively recall information; fill out and reread study guides.

3. Visual Aids: Use imagery and graphics to reinforce memory.

4. Reorganize Notes: Rewrite notes and practice applying concepts to real-life examples.

5. Nutritional Care: Proper nutrition and sleep are essential for memory consolidation.

6. Stay Calm: Use deep breathing and relaxation techniques while studying to enhance focus.

Conclusion

• Acknowledging the importance of care for mental health and nutrition in enhancing memory functioning.

• Continued practice and self-testing are encouraged to solidify learning.
