Abstract
The duo-trio is one of the basic sensory discrimination methods. There are various variants of the duo-trio including the double duo-trio (DDT), the dual reference duo-trio (DRDT), the paired duo-trio with AB and BA pairs (PDTAB), and the paired duo-trio with same (AA or BB) and different (AB or BA) pairs (PDTSD). Thurstonian models, that is, psychometric functions for the duo-trio and its four variants, DDT, DRDT, PDTAB, and PDTSD, are reviewed and developed in this paper. The theorized performances, that is, statistical powers of the four variants were explored and compared with the conventional duo-trio. R codes are developed and provided for analyses of the data of the duo-trio and its variants.
期刊介绍：
The Journal of Sensory Studies publishes original research and review articles, as well as expository and tutorial papers focusing on observational and experimental studies that lead to development and application of sensory and consumer (including behavior) methods to products such as food and beverage, medical, agricultural, biological, pharmaceutical, cosmetics, or other materials; information such as marketing and consumer information; or improvement of services based on sensory methods. All papers should show some advancement of sensory science in terms of methods. The journal does NOT publish papers that focus primarily on the application of standard sensory techniques to experimental variations in products unless the authors can show a unique application of sensory in an unusual way or in a new product category where sensory methods usually have not been applied.
