Task results
Typical ranges show the middle 80% of the matching age group using the same input method. They describe the reference sample, not a diagnostic cutoff. The marker shows your result. Red indicates poorer performance, yellow is near the lower-performance boundary, and green is within or better than the typical range. Higher accuracy and fewer errors stay green. Gray means no matching reference.
Sustained attention
What you did: You responded to city pictures and held back your response to mountain pictures.
What it measures: Sustained attention, response control, response speed and consistency of response times.
