What is the tunnel effect?
The tunnel effect is a receptive phenomenon where the brain will assume that the object persists when it disappears outside the occlusion and then reappears. For example, if one sees a horse behind a barn and on the other hand, a horse comes out, it will assume that it is the same horse if the animal trajectory makes sense. Although this may seem obvious, it actually includes some complicated cognitive maneuvering and plays an important role in visual processing of moving objects. The brain relies on the trajectory and the speed of the object before it disappears to calculate this information, although it tends to underestimate the travel time by the "tunnel", the time when it is invisible due to occlusion.
Through the tunnel effect, the brain perceives the persistent object moving with the same space and time, even if it disappears and reappears. Without this perception phenomenon, if something disappeared behind another object and reappeared, the brain might think it was another object. Cognitively the brain could be confused about what happened to the first ODThe yek, and is also a certain origin of the "new" object. The version of this can be seen while playing Peek-A-Boo with very young infants who still develop knowledge and perception and first do not have to understand what happens when a parent manipulates an object and out.
The tunnel effect may also include moving occlusion and stationary object. For example, a person standing on the corner of the street may notice a news stand in the opposite corner. When the car passes and closes the news rack, the brain assumes that it will reappear after the car is released and Thabude the same rack. Interestingly, in the studies of how the tunnel effect works, scientists have shown that tricks such as changing the color or size of the object do not deceive the brain and still read the object as permanent, rather than they think it is new.
a person's perception is difficult. Some perceptual phenomena are firmly involved and begin to manifest themselves at a very young age, while others evolve during the childhood phase and begin to ripen. To facilitate cognitive development is decisive pCity of the rich environment of children. Without stimuli, children will miss the chances of developing important cables in their brains and may never catch up.
