  • Title: Sensitivity to first- and second-order motion and form in children and adults.
    Author: Armstrong V, Maurer D, Lewis TL.
    Journal: Vision Res; 2009 Nov; 49(23):2774-81. PubMed ID: 19699227.
    Abstract:
    We compared the sensitivity of adults and children aged 3-10 years to first- and second-order motion and form. For first-order stimuli, at all ages sensitivity was better for motion than form, and motion thresholds were better at 6 Hz than at 1.5 Hz. For second-order stimuli, at all ages sensitivity was better for form than motion, and motion thresholds were better at 0.25 cyc/deg than at 1 cyc/deg. Thresholds became adult-like later for motion than for form and later for first-order than second-order stimuli. For first-order stimuli, the changes with age were larger and more protracted.
