"Constraints on distinguishing imagination from reality"


Dr Nadine Dijkstra, University College London, UK


Perceptual experience can be triggered by external signals coming from the outside world (perception) or by internal signals coming from memory (imagery). In the first part of this talk, I will discuss to what extent imagery and perception rely on similar neural mechanisms. I will show that the same brain regions represent imagined and perceived stimuli in similar ways but that the way these representations come about is different. Next, I will discuss to what extent this overlap leads to confusion between imagination and reality and which cues the brain could use to keep the two apart. I will argue for the need for a perceptual reality monitoring system that evaluates different sources of information to determine whether sensory signals reflect imagination or reality.
