an experimental design in which the procedures or participants used are similar but not identical to the situation of interest. For example, if researchers are interested in the effects of therapist gender on client perceptions of therapist trustworthiness, they may use undergraduate students who are not clients and provide simulated counseling dialogues that are typed and identified as offered by a male or female therapist. The results of such studies are assumed to offer a high degree of experimental control. Also called analogue model.
