ABSTRACT
This chapter aims to provide some of the developments of the concept of “stimulus error” derivable from the definition given to the notion by W. Kohler in the fifth chapter of his Gestalt Psychology. The stimulus error consists in taking some part of direct experience for one or another of the items that make up – in the list – its physical and physiological concomitants. In general, the possibility of mistaking the perceptual fact with the corresponding physical conditions holds only for some of the aspects of the perceptual fact, and only for some of the items listed in a-f. Thus, a further difficulty may arise: the physical events that are part the physical conditions of experience are imagined in phenomenal terms; are described as such; and then the descriptions are produced as phenomenological descriptions of that experience.
