Resilience to PTSD
Only about 10% of women and 20% of men react to traumatic situations and develop PTSD.
Holocaust survivors have shown remarkable resilience against traumatic situations.
All major religions of the world suggest surviving a trauma leads to
growth of the individual.

Freud suggested that we repress our painful intolerable, ideas, feelings and
thoughts resulting in anxiety.

The Learning Perspective
Learning theorists suggest that fear
conditioning leads to anxiety. This
anxiety then gets associated with other objects or events (stimulus
generalization) and gets reinforced.

The Learning Perspective
Fear responses, investigators believe, are inculcated through observational learning.

The Biological Perspective
Natural Selection has led our ancestors to learn to fear snakes,
spiders, and other animals. So fear preserves the species.
Twins studies suggest that our genes may be partly responsible for
developing fears and anxiety. Twins are more likely to share phobias.
