New research from MIT shows that theta-frequency brain waves act like radar scans across the cortex, influencing visual working memory and attention by affecting reaction times and accuracy depending on their phase, with potential implications for improving cognitive function in neurological disorders.
A study by Ben-Gurion University reveals that people underutilize their visual working memory (VWM), often recalling fewer items than their capacity allows. Participants typically remembered just one item at a time, despite being able to remember 3-4 items. This finding provides new insights into the real-life usage of VWM and suggests that further research is needed to understand the reasons behind this behavior.
Researchers have discovered that our capacity for visual working memory can be expanded when stimuli are meaningful. Previous theories suggested that visual working memory capacity was fixed, but this study found that individuals were able to retain more visual information when presented with recognizable objects compared to scrambled, meaningless versions of the same objects. This finding has implications for rethinking memory diagnostic tools and could impact how artificial intelligence systems model and manipulate human behavior.
