IIT Madras Researchers Find Key Physiological Markers to Predict and Manage Test Anxiety in Students

IIT Madras scientists have identified important physiological signals that could help predict and manage test anxiety among students. The research has been published in the Behavioural Brain Research, an international peer-reviewed journal publishing studies on the neurobiological basis of behaviour and cognitive processes in humans and animals.

IIT Madras Researchers Show How Brain-Heart Interaction Influences Exam Anxiety

The research finds that the interaction between the brain and the heart works differently in students who feel very anxious during tests. The focus was on two measurable markers: Frontal Alpha Asymmetry (a brain-wave pattern) and Heart Rate Variability (HRV), which shows how well the heart responds to stress. This new discovery offers a scientific path to support students under exam stress.

Students who had a negative frontal alpha asymmetry showed that their brains’ left and right sides were less balanced and had poorer heart regulation when under pressure. This breakdown in brain-heart communication could make them more anxious, especially in exam situations.

Because these markers are measurable, the research suggests we could identify high-risk students early. With early detection, strategies like breathing exercises or biofeedback could help them manage anxiety better. 

This is a major step in mental health and education. As exam stress rises in schools and colleges, tools based on such physiological markers could help reduce anxiety, improve performance, and support students’ well-being.
