In line with what she found, imagination was reported as more vivid when the same signals were also perceived, suggesting confusion between the two, but in contrast to what she found, we do not fail to notice things we simultaneously imagine, we are actually more likely to see them in the outside world. This combination of results can be very neatly explained by the idea that internal and external signals are intermixed to create one conscious experience. When this mixed signal is strong or vivid enough to cross a reality threshold, we think it reflects reality.
When the same object is perceived and imagined, the combined signal is stronger, so we are more likely to think this object is really out there. This also fits well with our daily experience. When we are waiting on the bus, we do not fail to see it because we are thinking about what it looks like—that would be very inconvenient, making you miss the bus because you are waiting for it.
Instead, we are more likely to see the bus when we are thinking of it, and sometimes, this also leads to confusion; for example, when we mistake the truck coming around the corner for the bus we are waiting for.
This means that there is no real categorical difference between imagination and reality, but that they are subjectively intermixed. When this combination of internal and external signals is strong enough, we believe it reflects reality. However, when, for some reason, internally generated signals are strong enough, they will be indistinguishable from reality. As it turns out, reality and imagination are completely intermixed in our brain which means that the separation between our inner world and the outside world is not as clear as we might like to think.
Her research focuses on the neural overlap between imagination and perception and how our brain can keep them apart or not. Dijkstra, N. Fundamental constraints on distinguishing reality from imagination. PsyArXiv Retrieved from: doi Friston, K. A free energy principle for the brain. Journal of Physiology - Paris , 70—87 Parr, T. Some may think that our thoughts are not in our control while others may believe that their focus creates their reality.
So before we proceed any further, let me explain how my interest began into what fundamentally alters our perception of reality. It was and I was locked away in a photographic dark room doing brain surgery on sharks. I was attempting a Masters degree in animal behaviour and was based in a remote marine research lab in New Zealand. I was conflicted. My intention to help conservation efforts by studying animal behaviour had lead me to hurt the very animals I was trying to protect. I made the reluctant decision to complete my degree and not let a single animal go to waste.
So I was surprised to learn that there are a small number of individuals who are completely blind to the act of visualisation. This phenomena is called Aphantasia, where individuals are completely unable to form any voluntary visualisation. Neuron , ; 4 : DOI: ScienceDaily, 10 December University of Colorado at Boulder.
