Do better in math: Don’t slouch-Be tall!

“When I saw the exam questions, I blanked out and slouched in defeat. Then I shifted to an erect/tall position and took a diaphragmatic breath. All of a sudden I remembered the answer.”                                                                                                                        College student

Anticipating that math is difficult, experiencing test anxiety, blanking out on exams, or being scared when asked to give class presentation are common experiences of many students.  Their thoughts include, “I am not good enough,“What will the other students think,”  “I am embarrassed and can’t remember what to say,” or “I only thought of the correct answer after it was all over.” Many students report some test anxiety: 32% report severe test anxiety, fear of math and blanking out on exams while less than 10 percent report minimal test anxiety, fear of math and blanking out on exams.

When students anticipate that they will perform poorly on an exam or class presentation, they tend to sit in a slouched or collapsed position, coincident with feelings of powerlessness, hopelessness and defeat. This posture not only communicates to others that they are powerless and defeated, it also decreases their self-esteem, mood and cognitive performance.  In previous research, Tsai et al (2016) and Peper et al (2017) observed that when participants sat in a slouched posture, they could access hopeless, helpless, powerless and defeated memories much more easily than when they sat in the upright/erect position.  In the upright position it was much easier to access positive and empowering memories. For numerous participants they also experienced being captured and flooded by emotions associated with defeat and hopelessness when they slouched. These feelings and memories associated with a slouched posture may affect how we feel and perform. Nair et al (2015) found that adopting an upright seated posture in the face of stress can maintain self-esteem, reduce negative mood, and increase positive mood as compared to a slumped posture. Furthermore, sitting upright increases rate of speech and reduces self-focus.” Posture may also affect our hormone levels. Harvard Social Psychologist Amy Cuddy has reported that sitting in a slouched posture (powerless position) decreased testosterone (the hormone associated dominance and assertiveness) and increased cortisol (the hormone associated with stress) and performance on a stressor test (Cuddy, 2012; Carney et al, 2010). 

This blog points out how posture significantly impacts math performance especially for students who have test anxiety, are fearful of math, and blank out on exams and is adapted from our published research article, Peper, E., Harvey, R., Mason, L., & Lin, I-M. (2018). Do better in math: How your body posture may change stereotype threat response. NeuroRegulation, 5(2), 67-74 

In our study 125 university students participated. Half the students sat in an erect position while the other half sat in a slouched position and were asked to mentally subtract 7 serially from 964 for 30 seconds. They then reversed the positions before repeating the math subtraction task beginning at 834. They rated the math task difficulty on a scale from 0 (none) to 10 (extreme).

The students rated the mental math significantly more difficult while sitting slouched than while sitting erect as shown in Figure 2.

For the students with the lowest 30% test anxiety, math difficulty and blanking out scores, there was no significant difference between slouched and erect positions in mental math performance.  More importantly, students with the highest 30% test anxiety, math difficulty and blanking out scores rated the math task significantly more difficult and some could not do it at all and blanked out in the slouched position as compared to the erect position as shown in Figure 3.

 The students with the highest test anxiety, math difficulty and blanking out scores also reported significantly more somatic symptoms as compared with those with the lowest scores as shown in Figure 4.

Posture affects mental math and inhibit abstract thinking. By incorporating posture changes clinicians and teachers may help students improve performance.  The slouched position was associated with increased difficulty in performing a math subtraction task for 15 seconds, especially for students reporting higher test anxiety, math difficulty and blanking out on exams. In contrast, slouched position had no significant effect on students who reported that they were not stressed about performance. For participants who report higher test anxiety, math difficulty and blanking out they also reported significant increase in breathing difficulty, neck and shoulder tension, headaches, depression and anxiety. Most likely, the students attribute physiological reactions such as increased heart rate and breathing changes negatively, which amplifies their negative self-perception and exacerbates their anxiety symptoms which then may inhibit their cognitive ability to perform on math tasks.

The slouched position combined with the somatic symptoms activate are part of the a “defense reaction.” The slouch posture evokes a classically conditioned response to protect oneself under conditions of perceived physical threat. The activation of this defense pattern is associated with reduced levels of abstract thinking and frontal cortical deactivation as observed in this study.  This biological defense response is triggered when the person expects the situation to be ‘dangerous’ and include conditions of social-evaluative threat. By changing posture to an erect/upright posture appears to inhibit the defense reaction; thus, the person may perform better on cognitive tasks. 


Head-upright/erect postures may make it easier to access ‘positive and empowering’ thoughts and memories, thereby helping students, especially those who are anxious or fearful of math and blank-out during exams,   Anxious students who also slouch may benefit from training with a posture feedback  devices such as the UpRight Go™[1].  We recommend that students use posture feedback to become aware of the situations that are associated with slouching, such as ergonomic factors (looking down at the screen), being tired, or having depressive thoughts or feeling of powerless and defeat. 

The moment students experience the feedback that they are slouching, they become aware and have the option to shift to an upright posture and perform interventions to counter the factors that caused the slouching.  These interventions included ergonomic changes of their computer or laptop, transforming self-critical thoughts to empowering thoughts, or taking a break or performing movements. When students practice these interventions for four weeks, they report an increase of confidence, decrease in stress levels and an improvement in health and performance (Colombo et al, 2017; Harvey et al, in press). Equally important is to teach the participants self-regulation strategies  such as slower breathing, heart rate variability training, and muscle relaxation to reduce symptoms. The training needs to be generalized and practiced at home, school or work.

We recommend that students guide themselves through the posture positions as described in this research while performing mental math to experience how posture impacts performance. This experiential practice may increase motivation to be tall since the participant can now have a choice based upon self-experience.

Take home message echoes what your mother said, “Don’t slouch. Sit up tall!” 

  • If you feel secure and safe, posture has little to no effect on performance–you can be collapsed or slouched.
  • If you are anxious and fearful, sitting tall/erect may improve your performance.
  • If you want to become aware when you slouch, posture feedback from a wearable posture feedback device such as an UpRight Go can provide vibration feedback each time you slouch. The feedback can be the reminder to sit tall and change your thoughts.
  • If you automatically slouch while working at the computer or sitting in chair, change your furniture so that you sit in an upright position while studying or watching digital devices.
  • If you experience significant somatic symptoms (e.g., headaches, breathing difficulty, neck and shoulder tension, or depression and anxiety) learn self-regulation skills such as slower diaphragmatic breathing and heartrate variability training in conjunction with transforming negative self-talk to positive self-talk to improve performance.

Changing posture may also impact other areas of one’s life besides improving math performance as illustrated by the report from a mother of ten-year old boy.  

”At the moment I am trying to be aware of the situation in front of me rather that reacting to it. For example, yesterday my son who is 10 had a bad mood and I did not know what had happened, and he at first refused to tell me. Because I was aware of the posture information I could help him open up by making him change his posture without knowing. He became more open and told me what had happened earlier and I could help him move forward.”
