Question 41

Experiment 9

A Developmental Psychologist wants to determine if you can increase prosocial behavior (e.g., sharing, helping others, saying thank you) in children by having them watch a cartoon demonstrating prosocial behavior vs. an educational cartoon (control condition). The Psychologist recruits 10 children to first watch the educational cartoon, followed by a 5-minute observational play period where the researcher records the number of times the children engage in prosocial behavior. Next, all 10 children watch the prosocial cartoon, which is followed by another 5-minute observational play period where the number of prosocial behaviors is again recorded for a 2^nd time. The Psychologist wants to determine if the prosocial cartoon increased prosocial behavior compared to the control condition.
