For each demonstration come that have an excellent centrally exhibited obsession mix to possess good jittered period ranging from 1020 and 1260 when you look at the increments from sixty ms. 2nd, users viewed the pictures of one or two reverse-sex professionals to possess 300 ms, among which was up coming replaced by the a dot before participant indicated the correct place by using the associated cello techniques (z for leftover, m to own best). Every demo concluded having a keen inter-demo interval between 1380 and you may 1620 ms inside increments from sixty ms. Once finishing 10 practice samples, players viewed all the you’ll be able to combinations of your own reverse-sex participants’ images (i.age., forty-five dyads) double, so for every fellow member in good dyad could well be exhibited due to the fact probe (we.e., the image changed by the mark) together with distractor visualize (we.age., the image maybe not changed by the dot) leading to a maximum of 100 examples.
