Featured are methods and systems for psychophysical assessment of number-sense acuity. Such methods include determining at least a display time based on participant related information (e.g., age) and selecting images for viewing by the participant based on the participant related information, the selected images having a complexity appropriate for the participant. Such methods further include displaying each selected image to the participant for the determined display time, the participant providing a reply to an assessment question after viewing each selected image, and determining a parameter representative of the psychophysical assessment of number-sense acuity based on each reply by the participant.
