Successful odor identification depends on (i) commonly encountered substances, (ii) a long-standing connection between an odor and its name, and (iii) aid in recalling the name. The absence of any one ingredient impairs performance dramatically, but the presence of all three permits ready identification of scores of substances, with performance seemingly limited only by the inherent confusability of the stimuli.
（i）常见物质；（ii）气味与其名称之间的长期联系；以及（iii）帮助回忆名称。缺少任何一个要素都会显著损害识别表现，但具备所有这三个要素就能轻易识别几十种物质，表现似乎仅受刺激物本身易混淆性的限制。
