Big Brains Can You Improve Your Working Memory and Attention? with Edward Awh
11 snips
Feb 5, 2026 Edward Awh, cognitive neuroscientist at the University of Chicago who studies attention and working memory. He discusses why our conscious capacity is so limited. He describes neural markers that track memory load and why some people are more consistent than others. He explains practical ways to support focus like exercise, cautions about brain-training apps, and how to monitor momentary cognitive capacity.

Episode notes
A Unified Neural Signal Tracks Item Count
- Awh's lab finds a neural signal that tracks how many items are being bound into a dynamic event regardless of sensory modality.
- This suggests a unified mechanism for tracking item count across vision and audition.
Consistency, Not Bigger Capacity, Matters
- High performers don't necessarily have larger capacity but load information more consistently into memory.
- Consistency in attentional focus distinguishes those who reach their capacity frequently from those who do not.
Overload Causes Information To Be Dropped
- When cognitive load exceeds capacity, the brain drops items rather than merely slowing down.
- Lower-capacity individuals are more prone to dropping information under overload.
