Mentally normal and healthy people also hallucinate

What is it about?

If different objects are repeatedly perceived together, then when later on only one of them is presented for perception, the other can be also experienced even though it is not actually present. This paper reviews respective studies from our lab. Basically, one of the main prerequisites for these "normal" hallucinations is direction of attention away from the place where the hallucinated object ultimately appears.

These studies may be useful for titrating and studying the differences between normal and pathological cases of hallucinations. The scientific facts that normal people can have illusions so easily help understand that eyewitness evidence from sincere individuals can not be always trusted.
