3
Q

What is the biologically preparedness theory?

“Behaviours that arose and helped early ancestors survive and reproduce in the EEA should still exist today”

4
Q

What is the EEA?

A

The environment of evolutionary adaptiveness

5
Q

Explain the fight or flight response in terms of the biological preparedness theory:

A

  • people today are more likely to have fears of dangerous things
6
Q

A
  • they are potentially poisonous running from them in the EEA would increase the chance of survival

A
  • it would stop you falling and injuring yourself, increasing survival
8
