Disease-avoidance model: factor analysis of common animal fears
Behaviour Research and Therapy
|January 1, 1994
Summary
Common animal fears may stem from disease avoidance. Disgust sensitivity is linked to fears of disease-relevant animals, not predatory ones, suggesting distinct fear mechanisms for different animal types.
Area of Science:
- Psychology
- Evolutionary Psychology
- Clinical Psychology
Background:
- Common animal fears are prevalent and can significantly impact quality of life.
- Existing models often focus on predatory threats, but disease avoidance may also play a crucial role.
Purpose of the Study:
- To investigate a disease-avoidance model of common animal fears.
- To differentiate fear responses based on animal categories (predatory vs. fear-relevant).
Main Methods:
- Two studies were conducted involving self-rated animal fears and psychological assessments.
- Study 1 used factor analysis to categorize animal fears.
- Study 2 examined correlations between disgust sensitivity, obsessive-compulsive traits, and fear of different animal categories.
Main Results:
- Factor analysis identified two main categories of animal fears: predatory and fear-relevant.
- Disgust sensitivity significantly correlated with fear of fear-relevant animals, but not predatory animals.
- Fear of fear-relevant animals was associated with obsessive washing, but not general obsessive behavior.
Conclusions:
- Findings support a disease-avoidance model for certain animal fears.
- Disgust sensitivity appears to be a key factor in fears related to disease-carrying animals.
- These results suggest distinct underlying mechanisms for different types of animal phobias.
