  Consider the two forms of Synthesis of Recognition in a Concept. In the form of binding, the phenomenon that he had in mind in the first kind of synthesis is now widely studied. Indeed, one model, Anne Treisman’s (1980) three-stage model, is very similar to all three stages of synthesis in Kant. According to Treisman and her colleagues, object recognition proceeds in three stages: first feature detection, then location of features on a map of locations, and then integration and identification of objects under concepts. This compares directly to Kant’s three-stage model of apprehension of features, association of features (reproduction), and recognition of integrated groups of under concepts (A98-A106). However, Kant’s second kind of recognition under concepts, the activity of tying multiple representations together into a global representation (A107–14), has received little attention.
