In this study, the participants were exposed to different conversations. The researcher wanted to be able to examine more than just one conversation. He wanted to have a variety of different conversations to be able to collect data from to help figure out the results. There were three different specific conversation pointers the researcher was looking for, one being a discussion of satisfaction (intimate-conversation), discussing everyday topics (a general conversation), and no treatment control condition. Each participating couple was assigned one of the topics listed above at random. Each couple was placed into a room by themselves to talk about the topic they were assigned. The participants were videotaped and after eight minutes of speaking to one another, the researcher interrupted and told the participants to move on to the next study. The researcher examined the video to see if the couples had stayed on the assigned topic. The results came as every couple was able to do
