Working Memory
A concept in cognitive psychology referring to the human capacity to simultaneously process and store information. Its limited capacity, approximately 7±2 information chunks, is closely related to the cognitive load imposed on developers by code complexity.
Core Facts
Psychologist George Miller proposed the "magical number 7±2" in 1956, revealing the bottleneck of human working memory.
Classic research by psychologist George Miller shows that human working memory can only process 7±2 chunks of information at a time.
Cowan's embedded-processes model holds that the effective capacity of working memory is closer to 4 chunks.
Timeline (last 90 days)
Human working memory capacity is limited, typically around 4±1 chunks.
Subsequent research revised the human brain's working memory capacity to approximately 4 chunks.
In pure voice interaction, when information arrives in rapid bursts, the human brain's working memory cannot keep up, making it a suboptimal way to convey information.
People with ADHD have relatively limited working memory capacity, and information that is out of their field of vision cognitively almost disappears, making them unable to rely on internalized reminder mechanisms to surface reminders automatically the way neurotypical individuals can
Human working memory capacity is limited, and simultaneously maintaining speaking fluency and logical organization creates competition for cognitive resources.
When typing, the text on the screen acts as external working memory that can be reviewed and modified at any time, thereby freeing up cognitive resources for thinking.
Working memory is the intermediate state during an Agent's operation, including information looked up, tools invoked, and the current step of the task.
Psycholinguistic research shows that verb-final structures increase working memory load.
Nelson Cowan revised the working memory capacity figure to a more conservative 3 to 5 chunks of information in 2001
Cognitive science research indicates that human working memory can only process 4±1 chunks of information at a time
