Exam 3: Experiments and Experimental Designs in Psychology

In order to support the theory that children will model adult aggressive behaviour, 20 children were shown a film in which several adults acted quite aggressively. The children were then allowed to play on a bouncy castle. They were observed and the number of aggressive responses they 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. It was predicted that the children seeing the aggressive film would produce more aggressive responses than those seeing the nature film and this was found to be the case. -4) Random allocation is used in the study described above to deal with the problem of:

10) One disadvantage of the experimental method in psychology is that:

9) One way to lessen the probability of non-equivalent groups is:

8) One major disadvantage of the independent samples experimental design is:

5) One major strength of the experimental method over other methods is that it:
