The aim of this study was to characterize further the experimental procedure proposed by Borgeat and Goulet in 1983. Subliminal activation auditory suggestions were expected to increase heart rate and skin conductance in presence of a stressing task. 20 subjects were alternately exposed to activating or neutral (random numbers) 25-dB suggestions masked by a 40-dB white noise. Analyses of variance and covariance indicated an effect of the activating suggestions on heart rate but not on skin conductance. Partly confirming previous results, the data support the reliability of heart rate and the importance of a stressing factor to reveal the effects of preconscious or subliminal stimulations.
