a Experiment procedure flow diagram, where NF indicates no feedback; H, M, and S refer to hard, medium, and soft blocks b View of experimental setup from the participant’s point of view c Sideview of the experimental setup. Fabric and computer monitor occlude the participant’s view of the block. d Example probes - participant needs to reach between 100% and 110% of the target aperture Et. If they undershoot or overshoot this target, they are required to try again
