A social psychologist is working with a developmental psychologist to study the effects of various behavioral interventions on aggressive behavior in children. They randomly select twenty girls and twenty boys. Each child is observed by a "blind" observer who counts the number of aggressive acts committed by the child. For three weeks, aggressive behavior by all children is ignored by the psychologist (Extinction). For the next three weeks, aggressive behavior is punished with a procedure called time-out (Time-out). For the final three weeks, aggressive behavior is ignored and non-aggressive behavior is rewarded with praise (Different reinforcement). The data are mean number of aggressive acts by each group at the end of each three-week period. The researchers are interested in whether
boys are more aggressive than girls, whether type of behavior treatment has an effect, and whether there is an interaction between gender and type of treatment. What parametric test would you choose to answer the question? What will be an ideal response?
