IAT consisted of five classification tasks administered in a sequential order on the computer screen. Block 1, 2 and 4 were learning blocks, whereas blocks 3 and 5 were critical to compute IAT scores. The order of the critical blocks was counterbalanced across participants. In each block, participants were required to classify stimuli by pressing one of two different keys on the computer keyboard (‘D’ and ‘K’). Instructions and key assignments were displayed on the computer screen before each block. Stimuli were presented at the center of the screen and remained visible until response.
