Working Memory Researchers have investigated how the mood, age, and sleep quality affects working memory of a person.
Working memory alludes to short-term memory or a cognitive system that temporarily holds the information in brain. It helps in reasoning, based on the situation and guides in decision-making.
With growing age, theses abilities decline. However, there are other factors which hamper these abilities. Low sleep quality and depressed mood are the two major reasons that affect in the long and short run.
The University of California, Berkeley, The University of California, Riverside, the University of Michigan, in Ann Arbor conducted the study.
Studies Analyzes Quantitative and Qualitative Aspects of Sleep and Mood
The Journal of the International Neuropsychological Society published the study. The group of scientists also studied if the factors affected the working memory individually or with each other’s influence.
The new research studies the factors affecting the working memory in terms of quantitative and qualitative aspects. Qualitative refers to connection of memories with these abilities. Whereas, quantitative refers to precision and strength of working memory.
Weiwei Zhang, one of the lead researchers stated other studies had already connected these factors individually to entire functioning of working memory. However, for the first time, a research analyses connection of memory with quantity and quality.
Zhang said that all factors, sleep quality, mood, and working memory are interrelated with each other. For instance, older people tend to experience more negative mood compared to young people. Moreover, poor sleep quality, as well affects the mood.
