For example, a researcher with a sample of 100. students might assign half of them to write about a traumatic event and the other half write about a neutral event. It spreads order effects evenly across the treatment conditions. Within-subjects experiments also make it easier for participants to guess the hypothesis. An alternative approach is to use a waitlistcontrolcondition, in which participants are told that they will receive the treatment but must wait until the participants in the treatment condition have already received it.

Explain the difference between between-subjects and within-subjects experiments, list some of the pros and cons of each approach, and decide which approach to use to answer a particular research question. In a within-subjects experiment, however, the same group of participants would judge the guilt of both an attractiveandan unattractive defendant.
