In a typical experiment we ask our participants to perform simple discrimination tasks about carefully calibrated stimuli. For example: “Which of these images has higher contrast?”, “On which side did you see this target stimulus?”, “Are these dots on the same object?”, etc. These types of experiments allow extremely precise, quantitative measurements of human visual abilities, which fortunately are similar in different subjects./wp-content/uploads/sites/2/2026/03/03112240/FHSE_SM-Profile_1600x1600px-scaled.jpg25602560
