| Abstract/Results: | ABSTRACT:
Using a well-established methodological paradigm to investigate the presentiment phenomenon and its extension to pre-alerting and guessing tasks, we planned to explore in this study whether participant heart rate signals could be used to predict whether randomly selected future stimuli would be pleasant or unpleasant. After evidence was found in Experiment 1 of different anticipatory signals before the perception of pleasant and unpleasant sounds, we further explored the effect by asking participants to block incoming unpleasant sounds. The prediction was tested in Experiment 2 using an explicit intuitive condition in which participants were informed when their physiological response suggested that the next sound would be unpleasant, and they were able to skip it by pressing the computer mouse. We also included an implicit condition in which incoming unpleasant sounds were automatically skipped, based on physiological response. Experiment 3 used only the implicit intuitive condition. In the implicit intuitive condition, we found an r 0.40 (Expt. 2) and an rs = 0.69 (Expt. 3) between the scores on the Tellegen Absorption Scale and the difference between blocked pleasant and unpleasant sounds. The total variance explained by Absorption and a measure of Expected Efficacy was R2corr = 0.105 (Expt.2) and 0.57 (Expt.3). The specific role of absorption in facilitating implicit intuition was confirmed by the low correlation, r = -0.22, with the difference between the blocked pleasant and unpleasant sounds in the explicit condition (Expt. 2). When participants were divided into high and low scorers on absorption, high absorbers obtained a statistically significant difference in the means of blocked pleasant and unpleasant sounds (Expt. 2 and Expt. 3), but only in the implicit condition. Overall, these results seem to suggest the possibility of exploiting anticipatory physiological signals to predict future events using implicit intuition.
