title: Binocular reaction times to contrast increments.
abstract: Binocular and monocular reaction times were measured in response to an abrupt increment in the standing contrast of a grating. For near threshold contrast increments the advantage of binocular over monocular viewing was substantial when the standing contrast was low, but this advantage was reduced at higher standing contrasts. With high contrast increments the advantage of binocular over monocular viewing was uninfluenced by standing contrast and exceeded the level expected from probability summation.
