Stimulus and you may experimental process
We put a book on the web speed relationships task one to combined the newest social-judgment paradigm (Somerville et al., 2006) plus the price matchmaking paradigm (Cooper et al., 2013). Members was basically told which they had been participating in a multi-school rates dating study and you will have been needed to fill in an electronic photographs from on their own with a basic phrase. In addition, at the time of the photographs submission, a standardized images of the fellow member (canned on the same dimensions and you will record because the experimental situation) are delivered to the fellow member to ensure that he/she is happy with the final images made available to its speed dates.

Once finishing the fresh pre-task rating course, members was in fact informed that what they had merely viewed was basically brand new rates schedules off their colleges engaging in that it opportunity. Such rate schedules and would done evaluations according to research by the earliest impressions regarding photo of the fellow member. In reality, the newest get toward participants’ images wasn’t created by genuine price dates however, controlled of the experimenter.
