Déjà Vu May Feel Like a Premonition, but It’s Not

Most people can relate to the unsettling experience of déjà vu, when you’re in a new situation but you feel like you’ve been there before. For some, that eerie feeling has an added twist: A sense that they feel like they know what’s going to happen next.

A new study investigating déjà vu shows that participants were no more likely to actually be able to tell the future than if they were blindly guessing — but when they were experiencing déjà vu, they felt like they could. The research, conducted by Anne Cleary of Colorado State University and former graduate student Alexander Claxton, is published in Psychological Science, a journal of the Association for Psychological Science.

Work from Cleary and others has shown that déjà vu is likely a memory phenomenon. It can occur when someone encounters a scenario that is similar to an actual memory, but they fail to recall the memory. For example, Cleary and collaborators have shown that déjà vu can be prompted by a scene that is spatially similar to a prior one.

“We cannot consciously remember the prior scene, but our brains recognize the similarity,” Cleary said. “That information comes through as the unsettling feeling that we’ve been there before, but we can’t pin down when or why.”

Cleary hypothesized that if déjà vu is a memory phenomenon, the feeling of prediction might also be a memory phenomenon.

In previously published research, Cleary and colleagues created virtual reality scenarios using the world presented by the Sims video game. Findings from this work revealed that participants were more likely to report déjà vu among scenes – like a junkyard, or a hedge garden — that spatially mapped onto scenes they had witnessed earlier. For example: This is a graphic showing different virtual scenes from the study

In her most recent experiments, Cleary created dynamic video scenes in which the participant was moved through a series of turns. To induce déjà vu, the researchers had them move through scenes that spatially mapped to the previous ones– at the last moment, the participants were asked what the final turn should be. In those moments, the participants also reported whether they were experiencing déjà vu and whether they felt they knew what the direction of the next turn should be.

About half the respondents felt a strong premonition during déjà vu. But they were no more likely to actually recall the correct answer – the turn they had previously seen in a spatially mapped, different scene – than if they were to choose randomly. In other words, participants who had the feeling of prediction were pretty confident they were right, but they usually weren’t.

Cleary and her lab are conducting follow-up experiments to probe this feeling of prediction. They wonder whether it is the familiarity process that drives the feeling. They’re also investigating whether people experience hindsight bias – that is, whether people will be convinced that they knew what was going to happen, after the fact.

“I think the reason people come up with psychic theories about déjà vu is that they are these mysterious, subjective experiences,” Cleary said. “Even scientists who don’t believe in past lives have whispered to me, ‘Do you have an explanation for why I have this?’ People look for explanations in different places. If you’re a scientist, you’re looking for the logical reason for why you just had this really weird experience.”

I respect the findings that individuals were not apt to predict the outcomes however if I find myself in a situation that I was in before can I not in some way expect an outcome? Doesn’t this in some way tie in to conditioned responses?
