FIGURE 1.

Experimental stimuli for the Dynamic Affect Recognition Task (DART), including both unmasked and newly‐added masked adult and child faces, as well as the pictorial response scale with emotion labels under each picture. (a) Stimuli from child actors were obtained from the NIMH‐ChEFS set (Egger et al., 2011). Adult stimuli were obtained from a validated stimulus set of amateur actors photographed at the University of Pennsylvania with standardized luminosity and distance. For the current study, the DART was adapted by adding standard surgical masks to stimuli using Photoshop Tools. (b) The task used a validated pictorial response scale to reduce reliance on verbal or written labels (see Supplemental Materials).
