# Deploying attentional control reduces irrelevant information in working memory
Working memory is efficient when it stores relevant information. What information that goes in working memory is being controlled by our central executive (based on Baddeley's model of working memory). Therefore the ability to deploy our Attentional control can make our use of working memory be more efficient.
This idea is related to the idea from flow: To control consciousness is to be able to focus attention at will.

Furthermore, it seems reasonable to suggest that the ability to effectively deploy attentional control could be the essential link for the earlier observed connection between working memory capacity and higher cognitive functioning (Johnson et al., 2013).

From the above studies it is evident that the prefrontal cortex plays a crucial role in working memory.
