Exam 5: Quasi-Experiments and Non-Experiments

9) The strict control of variables in a laboratory:

8) A field experiment is:

7) Which of the following pairs are both essential for a true experiment:

6) Mundane realism can be said to occur in an experiment:

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:

3) Babies are presented with two sets of stimuli. One set are coloured and the other set are not. Observers record how many times they choose to look at either coloured or plain stimuli. This design is a:

2) Participants are given a perceptual task to perform. Based on their scores on this task, they are divided into three groups: strong visualisers, moderate visualisers and weak visualisers. They are then given a memory task to complete in which they have to use concrete imagery in order to retain and recall a list of items. As predicted, strong visualisers are found to recall most items in the memory task. This is an example of:

10) One important disadvantage of research conducted in a laboratory is that:

4) Wallets containing information about their owner are dropped in a railway station. Half the wallets indicate that the owner is fairly wealthy. The others indicate the opposite. The number of wallets returned is counted and the prediction is that fewer 'wealthy owner' wallets will be returned. The design here is a:

5) It is part of a centre's policy to allocate its clients at random to one of their two drug rehabilitation group therapy days. One of the groups is about to come under the supervision of a new therapist who wishes to trial a new type of therapy. A psychologist decides to take before and after (6 months' therapy) measures of both groups. This would be an example of a:
