A person's working memory capacity is correlated with their brain's ability to actively ignore distraction, a new study reports.
Children from lower socioeconomic backgrounds, and whose mothers have lower levels of education, have weaker brain activity in areas of the brain associated with working memory and are more likely to experience attention problems.
Researchers report synchrony of brain waves within three regions of the brain can 'break down' when visual working memory load becomes too extensive to handle.
Children show improved ability in their math skills when they are trained to practice visual working memory and reasoning tasks.
Trying to retain too much information in our working memory can lead to a breakdown in communication between areas of the brain responsible for maintaining it, researchers say.
