Abstract
Recognition tests demonstrated unique features of odor memory. The forgetting curve over a span of one month showed a very slow decay from an initial performance of 85% correct recognition, a finding that contrasts with the rapid decay for stimuli presented to other sense modalities. The variables of labelling, codability, serial position, and retention interval had little or no effect on performance. Even the variables of familiarity and pleasantness, salient aspects of odor experience, had no effect on recognition. Hence, the connection between linguistic processing and odor recognition is weak.
