Final answer:
The main drawbacks of physiological reactions research are subjectivity, laboratory settings, and limited scope and analysis.
Step-by-step explanation:
The main drawbacks of physiological reactions research include:
- Subjectivity: Physiological reactions are difficult to measure and study empirically, leading to inconsistent definitions and results.
- Laboratory Setting: The subjects in these studies are often placed in controlled laboratory settings, which may not accurately represent real-life situations.
- Limited Scope and Analysis: Physiological reactions research often focuses on capturing thoughts and beliefs, rather than actual behaviors in real-life scenarios.
