4 of 13
What did Lepper et al do?
Told 28 kids a story about 'hupe' and 'hule' (made-up) in 2 different conditions- non-contingent condition and contingent condition.
5 of 13
What did the non-contingent condition involve?
14 kids split in 2- 7 told a story where mum tells kid they can have hupe then hule and the other 7 told hule then hype (counterbalancing).
6 of 13
What did the contingent condition involce?
Rest of kids split in 2- 7 told story where mother tells her child they can have hupe if they eat hule and 7 told story where kid can have hule if they eat hupe (counterbalanced).
7 of 13
What did Lepper et al find?
No preference in non-contingent condition but in contingent one children preferred the food that was used as a reward. Kids rated their preffered food as tasting better. If story was 'hule if you eat hupe' they'd claim hule tasted better.

Evaluate Lepper et al.
Good because isn't gender biased, has high int. validity= counterbalancing removes extr. variables & pre-decided opinions. Bad because, small sample size, age biased, no informed consent (but parental)= difficult to generalise, culture biased.

What did Duncker do?
looked at social suggestion on children's food choices- kids observed series of role models making food choices e.g. mum, randomer, fictional hero, friend and another child.
12 of 13
What did he find?
Greatest food preference change was in the children exposed to an older child, a friend, their mum or fictional hero. Most likely to eat unfamiliar food if mum ate it. Therefore- parental behaviour is essential to the process of learning food behv's.
