Tomkins posits nine innate affects, six of which are triggered by a different profiles of neural firing. Two are drive auxiliary affects, disgust and dissmell (dissmell was named contempt in his earlier work) In the Affect Imagery and Consciousness series of four volumes the number of innate affects was increased from eight to nine when he discovered that digust was rooted in the mechanism for regurgitation and dissmell rooted in the sense of smell. The dissmelling affect keeps one at a distance. The disgusting affect would rid one of something already taken in. The ninth affect in the list is shame-humiliation which is an affect auxiliary. It is triggered by interruption of either of the positive affects of enjoyment-joy or interest-excitement.
