Individual difference in SR curves. Note. Performance on cognitive tests (y-axis) is optimal for moderate noise levels (x-axis), and attenuated for both too low and too high noise levels. More noise is required for optimal performance in inattentive or low performing children compared to attentive or high performing children.
