Aknin, Hamlin, and Dunn (2012) Looked at Giving Behavior in Children

Aknin, Hamlin, and Dunn (2012) looked at giving behavior in children. What did they find?

A) Toddlers express more happiness when they get to keep a toy, but by first grade, giving the toy away appears to make them happier
B) Giving a toy to others who express an interest in the toy makes toddlers happier than playing with the toy themselves
C) Toddlers will share an unwanted toy with others, but keep desirable toys for themselves
D) Toddlers will imitate the sharing behaviors of others, but do not seem to get any joy out of it
