ABSTRACT

In a rating-scale task, participants place a numerical value on some aspect of each stimulus. This value can be used to determine how that stimulus compares on that dimension to other (similar) stimuli. While some tasks provide only the order of stimuli along a dimension, most also indicate precisely how large the difference between two stimuli is (e.g., A is twice as good as B, B is four times as good as C, etc.). Note that the task measures the subjective, perceived difference along the scale between two stimuli and not the objective distance between them.
