Evolutionary Explanation of Behavior

Why & How do Humans Evolve Psychologically?

Evolutionary Explanation of Behavior

This is called as GAME BOY!

Pokemon Fight

• FIGHT TO LEVEL UP!

• DIFFICULT OPPONENT = MORE EXPERIENCE POINTS

• MORE EXPERIENCE POINTS = EVOLUTION

Evolution = stronger pokemon = face more difficult opponents = less chance of dying

EVOLUTION:

ENVIRONMENTAL DEMANDS = EVOLVE = ADAPTATION = SURVIVE

evolutionary theory

• NEED TO SURVIVE AND REPRODUCE

• DIFFERENTIAL FITNESS

• SURVIVAL OF THE FITTEST

• NATURAL SELECTION

Evolutionary Explanation of Disgust

Curtis, Aunger, Rabie (2004)

The research

• 77.000 participants (165 countries)

• rate 20 photographs for disgust (1-5)

• Disease-salient (eg. organic looking-fluid) & less disease-salient (eg. chemical blue fluid)

• Disease salient stimuli have highest rating for disgust

• Females have highest level of disgust

• The older the person = less disgusted

• result = consistent across cultures
