Figure 1. Stimulus contrast and tests of visual function
Top: Examples of low (left) and high (right) contrast sine wave gratings. Simple stimuli like these are often used in perceptual learning experiments. Bottom Left: An example of a Snellen Eye chart used to measure visual acuity. Bottom Right: An example of a Campbell-Robson contrast sensitivity function (CSF) chart. See your own CSF: towards the top of the chart the white-black modulations should ‘blend in’ with the grey background. The inverted-U shaped curve you see indicates that contrast sensitivity is better for mid-range spatial frequencies than low or high ones. Playing action-based video games improves contrast sensitivity, effectively ‘pushing’ this curve upwards.
