Mar 12, 2025
Alan Baddeley, Emeritus experimental psychologist famed for the multi-component model of working memory. He discusses definitions of short-term and working memory, chunking and the episodic buffer, attention and executive control, neural correlates, applications to Alzheimer’s, schizophrenia and ADHD, memory and self-identity, emotion/imagery interventions, and future links between working memory and AI.

Episode notes
Short Term Memory Is Not One Thing
- Short-term memory is a confusing label with multiple meanings and is not a single coherent system.
- Baddeley distinguishes everyday talk (age-related forgetting), short-term span tasks, and the richer concept of working memory used in research.
Chunking Compresses Information Using Long Term Knowledge
- Chunking arises from working memory capacity limits and leverages long-term knowledge to compress information.
- The episodic buffer supports briefly holding integrated chunks (e.g., sentences or objects) that exceed simple phonological or visuospatial spans.
Designing UK Postal Codes For Memory
- Baddeley described designing UK postal codes using psychological principles to maximize memorability.
- He placed numbers to minimize error and later found the system widely used and remembered across the country.
