“…In each block participants are given a single stimulus, and are asked to categorize the stimulus according to word-pairs representing combinations of dichotomous superordinate concept (e.g., fruit vs. snack) and attribute valence categories (e.g., like vs. dislike; Petróczi et al, 2011 ; Brand et al, 2014b ; Schindler et al, 2015 ). However, as some topics do not have obvious dichotomous complementary categories (i.e., doping), researchers have also developed a four-block single-category IAT (SC-IAT) consisting of a single concept category, and two attribute categories (Karpinski and Steinman, 2006 ; Chan et al, 2017 ). The SC-IAT design is advantageous in measuring implicit doping attitude as the concept of “doping” does not have a clear contrast category.…”
