1. A psychological study explored whether playing violent video games made people more aggressive toward other people. 200 college students volunteered for the study. Half were randomly assigned to watch a violent video game called "Wolferstein 3D". The other half were randomly assigned to play a non-violent video game called "Myst". Then the students were asked to play a two person competitive game in they were told they could punish the other player by subjecting them to a loud blast of noise. The students who had played the violent video game punished their opponents more often, and more severely, than the students who had played the non-violent video game. The researchers concluded that violent video games caused aggressive behavior. Answer "TRUE" or "FALSE" to each question:

This is a designed experiment (controlled experiment). TRUE FALSE

This study will probably have a problem with response bias. TRUE FALSE

The researchers who organized the study were the control group. TRUE FALSE

This study will probably have a problem with lurking variables. TRUE FALSE
