Rothman, who works in consumer research at a food company, and Parker, who is associated with a guidance research and consumer insights consulting and testing firm, offer a manual on the application, construction, analysis, and interpretation of just- about-right (JAR) scales, for use in consumer testing in identifying whether product attributes are perceived at levels that are too high or low, or just about right. They cover the history of JAR scale usage, the mechanics of its construction, inappropriate and appropriate uses, benefits and risks, case studies, and alternatives. The manual, which is meant for sensory and market research professionals responsible for consumer testing and interpretation of consumer data, was developed by members of the Task Group E18.04.26, which is part of the ASTM Committee E18 on Sensory Evaluation. It does not discuss psychological or psychophysical processes related to scaling, basic practices of consumer testing, or general statistical principles in detail. No index is provided.
