Humans rely more on ‘inferred’ visual objects than ‘real’ ones
- May 16, 2017
- Humans treat ‘inferred’ visual objects generated by the brain as more reliable than external images from the real world, according to new research.
- “In such situations with the blind spot, the brain ‘fills in’ the missing information from its surroundings, resulting in no apparent difference in what we see,” says senior author Professor Peter König, from the University of Osnabrück’s Institute of Cognitive Science. “While this fill-in is normally accurate enough, it is mostly unreliable because no actual information from the real world ever reaches the brain. We wanted to find out if we typically handle this filled-in information differently to real, direct sensory information, or whether we treat it as equal.”
Visual thinkers are all too aware of this reality deficit in the “typical” perception of reality; I can’t say that the mechanism described here is the “cause” of discrepancies between “typical” perception and the greatly enhanced perception of visually-oriented brains, but it does point out that the typical human brain has evolved “short cuts” that result in varying accuracy in the perception of the environment. This deficit, combined with de facto “magical-social” thinking has dire consequences for survival.
