No matter how motivated you are, it is hard to learn and retrieve key knowledge and skills if you can only hold on to a limited amount of information in memory at one time. Working memory is an executive function that allows us to hold information in mind while working with it. Working memory is critical in the process of storing information in long-term memory. It is also critical in retrieving previously learned information from memory. In fact, most of the " work " in the memory system occurs in " working " memory where information is managed, manipulated and transformed. Working memory capacity differs from individual to individual. Students with working memory difficulties can hold fewer pieces of discrete information in their mind at any given moment. They hear what you said, or see what is presented, but as more information overwhelms their memory system they lose previous information needed to successfully complete the task. Once information is lost it is not likely to be retrieved. It is easy to see how the student can become frustrated and consequently stop paying attention. Working memory difficulties are common among students with Attention Deficit/Hyperactivity Disorder (AD/HD), learning disabilities, hearing loss, acquired brain injury and mental health issues.
