Tools to Enhance Working Memory & Attention

About this video

Huberman explains working memory, the system that holds small amounts of information in mind for short periods, and its close relationship to attention and focus. He walks listeners through a self-test: hearing sentences, then recalling each sentence’s final word, with remembering three to six final words classed as a high working memory span and fewer than three as low. Huberman explains that, in studies where subjects’ brains were imaged, shorter working memory span correlates with less dopamine available for release in the prefrontal cortex, while longer span correlates with more. He then turns to research on training and other zero-cost, supplement-based and prescription approaches to improving working memory, emphasising that a low score signals no global memory deficit.

Key takeaways

• Huberman defines working memory as holding small amounts of information in mind for short periods.
• Huberman’s self-test uses recall of sentence-final words to estimate working memory span.
• Huberman explains that working memory span correlates with prefrontal dopamine availability in imaging studies.
• Huberman stresses a low span score does not mean a global memory or dopamine deficit.
