what are 3 weaknesses of the 2 part process model
- not everyone who's had a traumatic experience develops a phobia, 50% of non-phobic people have had a bad encounter with a dog, this contradicts 2PPM as they should have developed a phobia, THEREFORE may be biological factors
only 2% of people with a water phobia reported an unpleasant experience with water, contradicts as it would be expected they had a traumatic experience to develop the phobia
- alternative explanations
biological preparedness, an innate predisposition to acquire certain fears that are passed down through evolution, issue because there are alternative explanations
