Unconscious Perception of Future Emotions: An Experiment in Presentiment
📄 Original study📌 Appears in:
Plain English Summary
What if your body could sense the future before your conscious mind knows? In this pioneering study, 31 participants viewed randomly selected photographs — some emotionally intense, some calm — while their skin conductance (a sweat-related arousal measure), heart rate, and blood flow were recorded. Remarkably, about one second before an intense photo appeared, their bodies already started reacting, even though the computer hadn't yet chosen the image. Combining all three body measures, the signal peaked at nearly 5 standard deviations — very strong statistically. This experiment became the template for dozens of follow-up studies on bodily anticipation of emotional events.
Abstract
Is consciousness limited to perception of the sensory present and memory of the past, or does it also have access to future information? In an experiment designed to explore this question, a computer was used to randomly select and present target photos from a pool of digitized photographs. Some targets labeled "calm" included landscapes and cheerful people; other targets labeled "extreme" included violent and erotic topics. Heart rate, blood volume, and electrodermal activity were recorded before, during and after presentation of the target photo to see whether the body would unconsciously respond differentially to the two types of future targets. Extreme targets were expected to produce classical orienting responses after the targets were displayed, and a "presentiment" (future feeling) effect was predicted to produce orienting pre-sponses before the pictures were displayed. Calm targets were expected to cause no unusual responses before or after the target was displayed. Four experiments, involving 31 participants who viewed a total of 1,060 target photos, showed the expected orienting response after the target photo was displayed. In accordance with a presentiment hypothesis, there was a clear orienting pre-sponse that peaked with a four standard error difference in physiological measures between extreme and calm targets one second before the target photo was displayed.
