Breathing Perception and Cognitive Performance Study

This study is looking at how different sounds you hear while breathing affect your perception of how hard you're breathing and your thinking abilities. Researchers are testing three different sound conditions: normal background noise, increased sound of your own breath, and listening to music through noise-canceling headphones. The goal is to see if changing these sounds can make breathing feel easier and improve your focus, especially when breathing is difficult. You might be able to join if you are between 18 and 40 years old, speak English, exercise regularly, and have normal lung function. The study will measure changes in your performance on a thinking test (Stroop Color-Word Test) and how intensely you perceive your breathing difficulty (dyspnea). The study plans to enroll 15 participants, but its current status is unclear.

Study design
This is an interventional study with an enrollment goal of 15 participants. It compares three different auditory feedback conditions during a breathing task.
What's involved
You will complete breathing tasks with different auditory feedback conditions. Before and after each task, you will take a Stroop Color-Word Test and report your perception of breathing difficulty. Each day's breathing task will last approximately 60 minutes.
Compensation
Not stated in the trial record.
Follow-up
Your cognitive performance and perception of dyspnea intensity will be measured before and after each day's breathing task, which lasts approximately 60 minutes.

Normal cognitive function assessed using the Montreal cognitive function test \[18\].
Body mass index (BMI) ≤ 35 kg/m2.
Females with a regular menstrual cycle that ranges from 21-35 days (eumenorrhea)

Are pregnant or could possibly be pregnant by self-report.
Are color blind.
Known allergy or hypersensitivity latex.

Resting blood pressure of \> 130mmHg systolic or 90 mmHg diastolic and/or resting pulse rate of \> 100 bpm.
Females with irregular menstrual cycles (oligomenorrhea) that ranges from 36-90 days, and females with the absence of a menstrual cycle (amenorrhea).
Taking birth control for the sole purpose of period cessation (eg., Mirena IUD)
  • Change in Stroop Color-Word Test Time PerformanceBefore and after each Day 1 breathing task (approximately 60 minutes in duration)

    Time performance on the Stroop Color-Word Test (min:sec) will be measured every 10 minutes during each breathing task.

  • Change in Stroop Color-Word Test Error PerformanceBefore and after each Day 1 breathing task (approximately 60 minutes in duration)

    The number of errors on the Stroop Color-Word Test will be measured will be measured every 10 minutes during each breathing task.

  • Change in Perception of Dyspnea IntensityBefore and after each Day 1 breathing task (approximately 60 minutes in duration)

    Participants will rate perception of dyspnea (breathing) intensity on a visual analog scale (VAS) every 5 minutes during each breathing task. The participant will draw a vertical marker line on a horizontal line (100mm), indicating their breathing perception from "not noticeable" (0mm) to "maximal imaginable intensity" (100mm).

  • Change in Perception of Dyspnea UnpleasantnessBefore and after each Day 1 breathing task (approximately 60 minutes in duration)

    Participants will rate perception of dyspnea (breathing) unpleasantness on a visual analog scale (VAS) every 5 minutes during each breathing task. The participant will draw a vertical marker line on a horizontal line (100mm), indicating their breathing perception from "not unpleasant" (0mm) to "maximal imaginable unpleasantness" (100mm).
