The biopsychosocial model of challenge and threat (BPS-CT) provides a framework for understanding cardiovascular responses during performance. This tutorial simplifies BPS-CT research for behavioral scientists.
Area of Science:
- Psychology
- Physiology
- Behavioral Science
Background:
- The biopsychosocial model of challenge and threat (BPS-CT) links psychological states to cardiovascular responses.
- Challenge and threat are motivational states influenced by perceived resources versus task demands.
- Understanding these states offers insights into motivated performance.
Purpose of the Study:
- To provide a comprehensive tutorial for conducting experiments using the BPS-CT model.
- To lower barriers for behavioral researchers unfamiliar with physiological concepts and BPS-CT methods.
- To centralize resources for deeper understanding and wider adoption of the BPS-CT approach.
Main Methods:
- The tutorial covers theoretical background, lab setup, data collection, and data analysis.
- It offers concrete recommendations for new researchers.
- Appendices provide additional details on data analysis and equipment.
Main Results:
- The tutorial aims to make BPS-CT research more accessible.
- It facilitates the study of subjective appraisals and their determinants.
- It supports the investigation of cardiovascular responses in motivated performance.
Conclusions:
- This tutorial simplifies the application of the BPS-CT model for behavioral researchers.
- It promotes greater accessibility to challenge and threat research.
- It enhances the understanding of psychological processes and physiological responses.
