Odour qualitative similarities were collected on 18 Ss, using 10 diverse stimuli. Responses were in numerical category scale form, and were analyzed individually and pooled, by a nonmetric multidimensional scaling program TORSCA. It is suggested that the data are consistent with a degenerate metric space configuration here called a reflected simplex. Implications for psycho-physical odour quality typologies are noted.
利用10种不同的刺激物,收集了18名受试者的气味质量相似性数据。反应采用数字类别量表形式,并通过非度量多维标度程序TORSCA进行单独分析和汇总分析。结果表明,这些数据与这里称为反射单纯形的退化度量空间配置一致。文中指出了对心理物理气味质量类型学的影响。
