Each of 32 Ss received I adaptation, 7 acquisition, and 2 extinction sessions in a 2 by 2 factorial design with delay and.25 sec trace procedures as one dimension and interstimulus intervals of.35 sec and 1.00 sec as the other. The chief findings were that: (a) heart rate (HR) responses conditioned more rapidly than nicitating membrane (NM) responses; (b) HR performance was directly related and NM performance inversely related to interstimulus interval; and (c) the trace procedure debilitated NM performance at the 1.00 sec interval
