This scale uses four, seven-point statements to measure the degree to which a person believes that a product reacts to changes in its environment in a stimulus/response manner but without learning to improve its performance over time.
The scale is composed of three, five-point semantic differentials that measure the degree to which a consumer believes that a particular product/brand accomplishes what it is supposed to do.
