(A) Schematic illustration of the stimuli used in Experiment 3. Spatial frequency was 0.2 cycles/degree (low spatial frequency) with the phase of each Gabor reversing sinusoidally at 10 Hz (high temporal frequency; left), or was 5 cycles/degree (high spatial frequency) reversing at 2 Hz (low temporal frequency; right). (B) Mean log contrast sensitivity for magnocellular (M; low spatial frequency/high temporal frequency) and parvocellular [P; high spatial frequency/low temporal frequency stimuli (±SEM)], by group. FXS = fragile X syndrome; NT = neurotypical; SF = spatial frequency; TF = temporal frequency.
