Methods and systems for psychophysical assessment of number-sense acuity

A method for psychophysical assessment of number-sense acuity that is performed on a microprocessor, said method comprising the step(s) of:

• determining at least a display time from a database including a plurality of possible display times, based on participant related information;
• selecting images from another database including a plurality of plural images based on the participant related information, the selected images having a complexity appropriate for the participant;
• 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.

A system for psychophysical assessment of number-sense acuity, said system comprising:

• a computer system including a processing unit;
• a software program for execution on the processing unit, said software program including code segments, instructions and criteria for:
• determining at least a display time from a database including a plurality of possible display times, based on participant related information;
• selecting images from another database including a plurality of plural images based on the participant related information, the selected images having a complexity appropriate for the participant;
• 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.
