| Abstract/Results: | ABSTRACT:
Physiological responses to arousing (vs. calm) stimuli arriving 3-7 seconds in the future have been described in peer-reviewed journals using five different physiological measures in at least four different laboratories. However, only a handful of these have used tasks in which participants must perform conscious guessing at targets. In order to eventually improve performance at intuitive guessing, understanding the mechanisms of physiological presentiment effects during the performance of behavioral guessing tasks is critical.
To address this gap in knowledge, we performed three experiments. Our hypothesis for all three experiments was that two measures of autonomic state, heart pulse period or inter-beat-interval (IBI) and skin conductance (SC), would both show distinct and significantly different patterns associated with future correct vs. incorrect guesses in a guessing task. In the first two experiments we show that at the group level, significant differences in heart period are observed, such that IBI is higher preceding a correct guess than an incorrect guess. However, at least at the group level, there was no SC difference associated with correctness or incorrectness of a future guess in either of the two experiments. The third experiment found no significant anticipatory effects. Finally, an exploratory analysis comparing data from all females to all males across the four experiments showed that while at the group level SC was not responsive to correctness of future guesses in any experiment, a robust sex difference in SC anticipatory responses exists, in which males have increased skin conductance preceding correct vs. incorrect guesses, while females show the reverse pattern.
None of the significant effects in any of the experiments or the post-hoc sex difference analysis could be explained by expectation bias. Reasons for the lack of a significant effect in the third experiment are discussed. Overall, the results support the hypothesis.
