I found an article on brains.org named Stress-a land mine for the brain by Dr. Kathie F. Nunley. She states stress is more than distressing but it is unsafe to the mind and body. In addition, she states it can initiate other problem and can hinder short-term memory. Furthermore, large amounts of stress associated with fear and anxiety can affect the learning process. Yet on the other hand, she states a small amount of stress can keep arousal levels elevated enough to finish a task.
As a student, I often feel stressed and overwhelmed. I do agree a small amount of stress keeps me aroused enough to be determine to complete my assignments and submit them on time.
Next I found an article Training and plasticity of working memory using the Walden Universities Library from the PsycINFO database. It is believed that our working memory can be improved by be enhanced by adaptive and extensive training in the brains frontal and parietal cortex, basal ganglia. In addition, Changes in the dopamine receptors. This training would consist of repetition, feedback, rehearsal, chunking and meta-cognitive strategies. This would be beneficial for individuals who have a low working memory to help with their academic performance.
