Effects of size and contrast on spatial summation and surround suppression in older adults. a Pre-training data for older adults. The results revealed spatial summation at low contrast and weak spatial suppression at high contrast, with no differences between horizontal and vertical motions. Data were fit with the model described in the “Methods” section. b Data for young adults shown for comparison purposes. All error bars are s.e.m.
