How your sleep and mood affect your working memory

Our working memory controls our daily decisions, language and speech factors. However, lack of sleep and mood can cause effects to it, both in short term and long term.

A study was recently conducted for testing the capacity of a person’s working memory from the ages of 21 to 77. It is found that as the person ages, the memory capacity decreases.

Another study has also proved that lack of sleep can cause a depressed mood, thereby allowing us the chance to make a bad decision. This shows the lack of memory quality.

“Other researchers have already linked each of these factors separately to overall working memory function, but our work looked at how these factors are associated with memory quality and quantity — the first time this has been done,” explains lead researcher Weiwei Zhang, Ph.D.
