1) in the Chapter 3 Exercises We Encountered a Study

1) In the chapter 3 exercises we encountered a study where 20 children were shown a film in which several adults acted quite aggressively. The children were then allowed to play on a bouncy castle; the play was observed and the number of aggressive responses produced was counted. A second group of 20 children served as controls and were shown a non-violent nature film. They also played on the bouncy castle. Children were allocated to conditions at random. This is an example of a:

A) Quasi-experiment
B) Natural experiment
C) Non-experiment
D) True experiment
