Deep Breathing

Discover the key to reducing test anxiety and amplifying attention through deep breathing, made achievable with electroencephalography devices.

Deep Breathing Intervention for Test Anxiety

How Findings from Deep Breathing Can Help Your Students

  • Taking deep breaths before a test:
    • Reduces test anxiety
    • Improves attentional control / focus in primary school aged students

  • Brain activity observed during deep breathing relate to:
    • Enhanced performance in attentional focus and in (timed math fluency) test performance

  • Know that it is possible to collect neuroimaging data from students in schools using mobile electroencephalography* (EEG) devices
    • What does this mean for me?

      Previously, collecting data like EEG from students had its difficulties. Unlike the low cost, lightweight, wireless, mobile EEG headsets used in this project, conventional EEG systems tended to be very expensive, cumbersome to set up and uncomfortable for students. 

      One could hence infer that before the emergence of these low cost EEG headsets, measuring electrical brain activities of students in a classroom setting was not likely to be possible. 

      Therefore, these low cost EEG headsets bring about new possibilities to:

      • Collect EEG data that is ecologically-valid, in situ, large-scale and school-based!

Question-Icon Why Deep Breathing?

Test anxiety is a non-trivial and prevalent problem for school-going children around the world, especially in societies with high-stakes examinations. According to a study by von der Embse, Barterian, & Segool, 2013, 10-40% of students, some as young as age 7, suffer from test anxiety.

The Detriments of Test Anxiety

Potentially detrimental to children’s psychological well-being and performance, test anxiety can limit children’s test performance and hinder future educational and career progression. Unfortunately, test anxiety is also associated with negative outcomes ranging from low achievement, depression, and suicide ideation.

Hence early intervention in schools to equip students with emotional management skills, can mitigate such adverse effects of test anxiety (Khng and Mane, 2020). One such intervention, could be the introduction of deep breathing as a technique to help students with test anxiety.

How Was the Research Carried Out?

The research consisted of a pilot study and a main study. In the pilot study involving P5 students, EEG data was collected to compare the quality and pattern of EEG data between a consumer-grade EEG device and a clinical-grade EEG device.

In the main study involving both P5 and S1 students, a comparison between a deep breathing intervention group and a control group of students was made to measure pre-to-post-test changes in:

  • Self-reported feelings of anxiety
  • Timed Math fluency test performance
  • Self-reported state-of-mind
  • Behavioural and EEG measures of attentional focus under evaluative stress instructions


Question-Icon Key Findings

  • Taking deep breaths before a test is a simple intervention that can reduce test anxiety in primary school aged students and improve attentional control/focus
  • Deep breathing has effects reflected in brain activity, which is related to enhanced performance in attentional focus and (timed Math fluency) test performance
  • This study breaks new ground in the local educational neuroscience landscape by bringing neuroimaging into schools and demonstrating the feasibility of collecting electroencephalography (EEG) data from students in schools


What Does this Mean for Teaching and Learning?

  • Teachers can teach students deep breathing to self-regulate their emotions.
    • This in turn helps students cope with their test anxiety, allowing for better attentional focus, which is related to better performance.
  • Schools can consider incorporating deep breathing as part of students’ learning experience.
