Sight Distance and Reaction Time. Sight Distance. Sight distance means the distance from which you can see and identify a hazard. You often see an object before youâre able to identify it as a hazard. If the stopping distance to an object is greater than the sight distance, youâre in danger of hitting the object.
The major methodology of this approach is the single-case experiment, or N = 1 design. Although there are many kinds of N = 1 designs, the most common are the ABAB design and the multiple-baseline design. An ABAB design, or reversal design, allows a researcher to confirm a treatment effect by showing that behavior changes systematically with conditions of No Treatment (baseline) and Treatment.
