An investigation of a subject with complete anosmia of a year's duration. Two control subjects were used. Taste sensitivity of the subject was found normal; it had been neither impaired nor (by compensation for the anosmic loss) made more acute; yet the subject's ability to name correctly food stimuli put into his mouth when vision was excluded excelled that of the controls when vision and smell were excluded. It is believed that this heightened perceptual ability is the result of practice in attending to and relying upon secondary cues. Bibliography of 27 titles.
