For each trial come with a great centrally demonstrated fixation cross to have a great jittered stage between 1020 and you can 1260 during the increments of sixty ms. 2nd, professionals viewed the images off several opposite-sex users having three hundred ms, among which had been then changed by the a dot up until the new member conveyed a correct location using the associated piano tips (z having leftover, meters to possess proper). All of the demonstration ended that have an enthusiastic inter-demo interval anywhere between 1380 and you will 1620 ms in the increments of 60 ms. Shortly after completing 10 practice products, professionals viewed all of the it is possible to combos of reverse-sex participants’ photographs (we.e., 45 dyads) twice, thus for every single fellow member during the a great dyad would-be shown due to the fact probe (i.e., the picture changed by mark) while the distractor visualize (i.e., the picture not replaced by the dot) leading to a total of 100 samples.
