Human Brain Prevents Multitasking With A “Unified” Bottleneck
“Although the human brain is a very complex structure, it’s still not big or efficient enough to process every single thing we see, hear, and do.
Sometimes this limitation is a good thing, since it forces our brains to filter out minor details that we don’t need to dwell on. Other times it’s more of a hassle, since it interferes with how we process information.
Researchers previously thought that different processes in the brain were subject to separate bottlenecks.
For example, the process of reading a map might be limited by a very different mechanism than the act of evaluating ideas and forming opinions.
However, new research in PNAS suggests that a “unified” bottleneck may restrict our ability to perform very different cognitive processes simultaneously.”
