Abstract:
Predictability of aversive events impacts the development and maintenance of anxiety, particularly panic disorder. Although animal studies typically have found a preference for signaled (predictable) over unsignaled (unpredictable) aversive events, results of research with human participants have been less clear. Using a panic-relevant paradigm, the authors examined predictability preference with humans as a function of anxiety sensitivity and gender during repeated administrations of 20% carbon-dioxide-enriched air. Participants preferred predictable administrations, with high-anxiety individuals showing greater preference than low-anxiety individuals and women showing greater preference than men. In addition to providing information to better understand human predictability preference for panic-related events, results also may aid in determining the applicability of predictability to the cognitive-behavioral treatment of panic disorder.

Respiratory Volumes and Capacities I
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
