To see if phobias of snakes could be more easily conditioned than phobias of faces or houses, indicating a biological preparedness to develop phobias of certain objects
1 of 8
What methodology did Ohman use?
A laboratory experiment (with participants linked to a machine which would deliver shocks after some pictures, fear reaction measured by skin conductance)
2 of 8
How many participants took part in Ohman's study?
64 paid volunteers
3 of 8
What experimental design did Ohman use?
Independant design. With participants in either snakes, faces or houses condition
4 of 8
What were the participants asked to rate the shock they recieved as?
Uncomfortable but not painful
5 of 8
How long were the pictures presented for ?
8 seconds
6 of 8
What were the average skin conductance results following the shocks after pictures for snakes, faces & houses?
Snakes = 0.062 , Faces&Houses = 0.048
7 of 8
What conclusion did Ohman make from the results of the study?
Participants were more likely to show fear reactions to snakes than houses or faces, so this shows a biological preparedness to develop phobias to objects that may cause danger eg. snakes
