Figure 2. (A) Trial outline for a practice block in the PIAT. After pressing the dot (I), participants categorize the image they are presented with by tapping on the correct concept (faces), attribute dimension (positive/negative scenes), or a combination of the two appearing in the top left and right corner of the screen (II). Participants then receive feedback in the form of a thumbs-up or -down (III, presented for 2 s). Next, a new dot appears in order to start the next trial (IV, V). (B) Trial outline for the critical blocks of the adult PIAT. The trials in the critical blocks follow the same procedure as in the other blocks. In the child PIAT, attribute images are replaced by cartoon figures.
