Memory: Clive Wearing Case and Key Concepts

Clive Wearing Case Study

• Background:
  • Clive Wearing: Accomplished London musician.
  • 1985, at age 47, contracted rare Herpes encephalitis virus.
  • Virus ravaged his central nervous system.
• Effects on Memory:
  • Unable to remember past events or form new memories.
  • Recognizes his wife but can never recall last seeing her.
  • Demonstrates extreme and chronic amnesia.

Importance of Memory

• Helps make us who we are.
  • Recognizing loved ones.
  • Recalling past joys.
  • Remembering basic functions like walking, talking.
• Memory connects past to present and helps us plan for the future.
• Memory isn’t all or nothing.
  • Some memories are processed automatically (like speaking English, playing the piano).

Accessing Memories

• Three Methods:
  • Recall: Retrieving information from memory (e.g., fill-in-the-blank tests).
  • Recognition: Identifying information when presented with it (e.g., multiple-choice tests).
  • Relearning: Refreshing old information.

Memory Formation

• Stages (Atkinson and Shiffrin Model):
  • Encoding: Initial recording of information.
  • Storage: Keeping information for future use.
  • Retrieval: Accessing stored information.
• Sensory Memory: Immediate, fleeting memory from sensory input.
• Short-term Memory: Holds 4-7 bits of information briefly (under 30 seconds).
  • Rehearsal can help transfer to long-term memory.
• Long-term Memory: Durable, spacious storage for all knowledge, skills, and experiences.

Working Memory

• Updated concept of short-term memory.
• Involves transferring short-term information to long-term storage.
• Processes:
  • Explicit: Conscious, active storage (e.g., studying facts).
  • Implicit: Unconscious, automatic storage (e.g., conditioned responses).
• Types of Long-term Memory:
  • Procedural Memory: Remembering how to do things (e.g., riding a bike).
  • Episodic Memory: Memories tied to specific life episodes.

Memory Improvement Techniques

• Mnemonics:
  • Acronyms help organize information (e.g., ROY G. BIV).
• Chunking:
  • Breaking information into manageable units (e.g., phone numbers).
• Levels of Processing:
  • Shallow Processing: Basic auditory or visual levels.
  • Deep Processing: Semantic encoding based on meaning.
  • Personal Relevance: Connecting information to personal experiences enhances retention.

Conclusion

• Memory constantly shapes our brain, life, and identity.
• Clive Wearing's case illustrates the importance of memory in defining oneself.
• Memory helps us learn from the past and navigate the present and future.
