Most of us are aware that thoughts affect our body; however, we often overlook the impact of this effect. To demonstrate the power of visualization, participants are guided through a lemon imagery. In a study with 131 college students, 94% report an increase in salivation which is a parasympathetic nervous system response. The participants now know–not believe–that visualization affects physiology. Once salivation has been experienced, participants may apply other visualization techniques to change their physiology and behavior. Through visualization we communicate with our autonomic nervous system which can provide a matrix for self-healing and enhanced performance. In addition, the guided practice shows that almost everyone holds their breath when asked to tighten their muscles and some people have difficulty relaxing after tightening. Once aware, the person can and continue to breathe and relax the muscles. Enjoy the guided exercise, Mindbody connection: Lemon Imagery.

“I couldn’t belief it. I thought that I was strong and yet, I could not resist the downward pressure when I recalled a hopeless and helpless memory. Yet a minute later, I could easily resist the downward pressure on my arm when I thought of a positive and empower memory. I now understand how thoughts affect me.”
Thoughts/emotions affect body and body affects thoughts and emotions is the basis of the psychophysiological principle formulated by the biofeedback pioneers Elmer and Alice Green. The language we use, the thoughts we contemplate, the worries and ruminations that preoccupy us may impact our health.
Changing thoughts is the basis of cognitive behavior therapy and practitioners often teach clients to become aware of their negative thoughts and transform the internal language from hopeless, helpless, or powerless to empowered and positive. Think and visualize what you want and not what you do not want. For example, state, “I have studied and I will perform as best as I can” or “I choose to be a non-smoker instead of stating, “I hope I do not fail the exam” or “I want to stop smoking.” The more you imagine what you what in graphic detail, the more likely will it occur.
Most people rationally accept that thoughts may affect their body; however, it is abstract and not a felt experience. Also, some people have less awareness of the mind-body connection unless it causes discomfort. Our attention tends to be captured by visual and auditory stimuli that constantly bombard us so that we are d less aware of the subtle somatic changes.
This guided practice explores what happens when you recall helpless, hopeless, powerless or defeated memories as compared to recalling empowering positive memories. It allows a person to experience–instead of believing—how thoughts impact the body. 98% of participants felt significantly weaker after recalling the helpless, hopeless, powerless or defeated memories. Once the participants have experienced the effect, they realize how thoughts effect their body.
The loss of strength is metaphor of what may happen to our immune system and health. Do you want to be stronger or weaker? The challenge in transforming thoughts is that they occur automatically and we often doubt that we can change them. The key is to become aware of the onset of the thought and transform the thought. Thoughts are habit patterns and the more you practice a habit, the more it becomes automatic. Enjoy the experiential exercise, Mind-body/Bodymind-connection: Muscle testing.

“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™. 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.”
