Test of an orienting-reaction-recovery account of short-interval autonomic conditioning.
The electrodermal and plethysmographic components of the orienting reaction in 24 subjects were examined in a conditioning-analog arrangement (tones and lights patterned analogously to CS and UCS presentations in classical conditioning) in order to test the orienting-reaction-recovery (ORR) account according to which apparent short-interval autonomic conditioning (SIAC) can be completely accounted for by an ORR effect. The form of the test was to see whether ORR following change from a repeatedly presented forward ('CS-UCS') analog would exceed that to change from a backward ('UCS-CS') analog, as is the case in SIAC with CS-alone test trials following repeated CS-UCS versus UCS-CS pairings. The results did not support the ORR account, although they were shown to be consistent with the relevant experimental literature, when critically examined, and to provide internal evidence for the adequacy of the present test of this particular formulation of the ORR account of SIAC.
