Behaviorally Inhibited Individuals Exhibit Greater Minute Ventilation and Breathing Frequency Than Non-Inhibited Individuals When Breathing 7.0% CO2 Versus 4.5% CO2 — Presentation Detail — Celebration of Scholars

Instructions

Student presentations must have a faculty sponsor.

Abstracts must include a title and a description of the research, scholarship, or creative work. The description should be 150-225 words in length and constructed in a format or style appropriate for the presenter’s discipline.

The following points should be addressed within the selected format or style for the abstract:

A clear statement of the problem or question you pursued, or the scholarly goal or creative theme achieved in your work.
A brief comment about the significance or uniqueness of the work.
A clear description of the methods used to achieve the purpose or goals for the work.
A statement of the conclusions, results, outcomes, or recommendations, or if the work is still in progress, the results you expect to report at the event.

Presenter photographs should be head and shoulder shots comparable to passport photos.

Abstract

Behavioral inhibition (BI) is a temperament in which an individual tends to avoid unfamiliar situations or environments. Individuals who are behaviorally inhibited are more vulnerable to developing an anxiety disorder when placed under stressful conditions. BI individuals also learn faster and are slower to stop the response to a stimulus (Sheynin, 2005; Servatius, 2008). Our lab over the past several years has been investigating the relationship between a respiratory stress response to 4.5% CO2, 7.0% CO2, and BI. BI is characterized by avoidance behavior, aimed to reduce the fear of a certain stimulus. In this study, a computer game was used as an aversive stimulus to detect BI. 4.5% CO2 and 7.0% CO2 was administered as a mild respiratory stimulus to detect differences in those with BI compared to those without. One indication of PTSD is avoidance behaviors. 4.5% CO2 decreases the pH of the blood, hence causing an increase in frequency of breathing (FBR) , tidal volume (VT) , and inspired minute ventilation (VI). 7.0% CO2 would elicit a greater response, thus these changes in FBR, VT, and VI would be greater than 4.5% CO2. We hypothesize that individuals with behavioral inhibition will have a greater sensitivity to CO2, therefore, they will exhibit a greater respiratory and heart rate response in all parameters. Subsequently, those that are behaviorally inhibited will have a greater response to both 7.0% and 4.5% CO2 than those that are non behaviorally inhibited. BI and non-BI individuals were separated based on Adult Measure of Behavioral Inhibition (AMBI) and Retrospective Measure of Behavioral Inhibition (RMBI). Heart rate and respiratory data were collected using a BioPac computer data collection system while breathing 7.0% CO2 or 4.5% CO2.
