Test anxiety is almost universal.In fact, it is unusual to find a student who doesn’t approach a big test without a high level of anxiety.Test anxiety can cause a host of problems in students, such as upset stomach, headache, loss of focus, fear, irritability, anger and even depression.New research is helping to better define how emotional stress and anxiety affect learning and academic performance.Stressful emotions can inhibit a student’s ability to absorb, retain and recall information.Anxiety creates a kind of “noise” or “mental static” in the brain that blocks our ability to retrieve what’s stored in memory and also greatly impairs our ability to comprehend and reason.The key to understanding how anxiety inhibits cognitive and physical performance lies in understanding how emotions affect the rhythmic activity in the nervous system.Feelings such as frustration, fear, anger and anxiety cause the neural activity in the two branches of the autonomic nervous system to get out of sync(同步).This, in turn, affects the synchronized activity in the brain, disrupting our ability to think clearly.On the other hand, uplifting feelings such as appreciation lead to increased harmony and synchronization in the brain and nervous system, which facilitates our ability to think more clearly.Research has shown that providing students with tools and strategies that build both emotional skills and healthy physical habits when preparing for a test can help them overcome test anxiety and the associated symptoms, while improving their ability to prepare for and perform on critical testing.It’s important to help students identify what they are feeling and give them tools that will help them learn to manage emotions such as anxiety, self-doubt, anger or frustration.The proper physical habits enable students to have enough energy and stamina for their brain to do its job of thinking and analyzing for a sustained period of time.
