Ep.51. Can You Tune Out Distractions? Working Memory Capacity May Be the Key

"Working Memory Capacity as Executive Attention" by Randall W. Engle Summary This academic paper explores the concept of working memory capacity (WMC), arguing that it's distinct from short-term memory and significantly contributes to general fluid intelligence. The author posits that WMC, essentially executive attention, is crucial for managing interference and maintaining task goals. Research using tasks like the Stroop and antisaccade tests demonstrates that individuals with high WMC exhibit superior ability to control attention and resist interference, leading to better performance on complex cognitive tasks. The study uses statistical modelling to support the claim that WMC, not simply memory storage, is the key factor predicting success in higher-order cognitive functions.
