Any manipulation of A is expected to result in a change in the effect. Study notes, videos, interactive activities and more! allows researchers to compare participants who have received the treatment with participants who are not currently receiving it but who still expect to improve (eventually).

In practice, a full sequence of conditionsone for each participant expected to be in the experimentis usually created ahead of time, and each new participant is assigned to the next condition in the sequence as he or she is tested. In a within-subjects experiment, however, the same group of participants would judge the guilt of both an attractiveandan unattractive defendant.

Random assignment is a method for assigning participants in a sample to the different conditions, and it is an important element of all experimental research in psychology and other fields too. Figure 6.2shows some hypothetical results in which participants in a treatment condition improved more on average than participants in a no-treatment control condition. a process of arranging a series of experimental conditions or treatments in such a way that every possible sequence of conditions is given at least once during the study. To counterbalance something means to balance or correct it with something that has an equal but opposite effect.
