The position selected by the rater is then interpreted as a numerical score by a computer. This approach has the benefit of allowing much finer distinctions, up to 256 in many such studies, to be recorded than is the case when a simple Likert scale is used. At the same time, however, raters using a sliding scale approach are unaware of the individual gradients, raising questions about the reliability of these fine distinctions.
