However, contrary to the position of Suboski et al (1972), there was adequate evidence for reliable autonomic conditioning in that reliable differentiation was obtained in the studies by Furedy (1970), Furedy and Doob (1971a, Experiment III), Furedy and Doob (1971b), and in the present study in the case of the FIR GSR and the VPC.
