Participation of Description in Experimentation as an Auxiliary Stimulus Function. Note. Solid rectangles denote scientific workers or events of study. Dotted rectangles denote substitutional stimulus functions. Solid bidirectional arrows denote functional contact whereas the dotted bidirectional arrow denotes dual contact with formal and substitutional functions of events of study. The large solid black line segregates different interactions, because the scientific worker must first contact descriptions of events for such an interaction to be substitutionally present in experimental situations. Note that the psychological events represented here are simplified but could be more elaborate (see Fig. 1)
