A study from Karolinska Institutet shows, that
our imagination may affect how we experience the world more than we perhaps think.
What we imagine hearing or seeing 'in our head' can change our actual perception.
A new study sheds new light on a classic question in psychology and neuroscience:
How do our brains combine information from the different senses?
"However, what this study shows is that our imagination of a sound or a shape changes how we perceive the world
around us in the same way actually hearing that sound or seeing that shape does. Specifically, we found that
what we imagine hearing can change what we actually see, and what we imagine seeing can change what we actually hear."
The study consists of a series of experiments that make use of illusions in which sensory information from
one sense changes or distorts one's perception of another sense. Ninety-six healthy volunteers participated
In the first experiment, participants experienced the illusion that two passing objects collided rather
than passed by one-another when they imagined a sound at the moment the two objects met.
In a second experiment, the participants' spatial perception of a sound was biased towards a location where
they imagined seeing the brief appearance of a white circle. In the third experiment, the participants'
perception of what a person was saying was changed by their imagination of a particular sound.
According to the scientists, the results of the current study may be useful in understanding the mechanisms
by which the brain fails to distinguish between thought and reality in certain psychiatric disorders such as
Another area of use could be research on brain computer interfaces, where paralyzed individuals'
imagination is used to control virtual and artificial devices.
"This is the first set of experiments to definitively establish that the sensory signals generated by one's
imagination are strong enough to change one's real-world perception of a different sensory modality", says
Professor Henrik Ehrsson, the principle investigator behind the study.
Do We Live In A Computer Simulation Created By An Advanced Alien Civilization?
The captivating idea that we might be living in 3 dimensional holographic simulation has been put forward by various scientists.
We will explore this mind-boggling idea further and examine some intriguing questions.
If we suspect that we are programmed beings living inside a simulation is there any way for us to find out if this is true?
Is it possible to change the outcome of this virtual game?
Death Is Just An Illusion:
We Continue To Live In A Parallel Universe
For as long as anyone can remember philosophers, scientists and religious men have pondered what happens after death.
Is there life after death, or do we just vanish into the great unknown?
There is also a possibility there is no such thing as what we usually define as death.
A new scientific theory suggests that death is not the terminal event we think.
