The arts of manipulation have been used throughout time and history. Visual illusion on the other hand is used in our daily lives, in social media, in films and in advertising. To understand how visual manipulation is maximized we will have to distinguish the behaviors and perception of human beings. Human perception is limited to the quantity and quality of processing and the overall requirements of our perceptual system. Say no to plagiarism.

All in all, human perception seeks perfection and therefore processes the two halves of the image in a more complex and comprehensive way. Likewise our brain fills in the gaps in images to produce a complete image and the reason is that our brain does not just process external information, but actively interprets it. For this reason, visual illusions are possible and mental manipulation tricks are formed. Visual illusions are usually used by neuroscientists to dissociate the neural activity that corresponds to the perception of the stimulus from the neuronal activity that corresponds to physical reality. These are usually used in illusions such as the Penrose Triangle and the Blivet. Magicians usually manipulate their audience into perceiving their tricks. They aim to manipulate the attention and awareness of their audience. (2008) leaves for example the spoon bending trick, it seems to the audience that the magician is bending the spoon using only the power of the mind. What actually happens is that the magicians hold the spoon horizontally and shake it up and down. This illusion is based on the fact that "end-stopped neurons (i.e., neurons that respond to both motion and terminating edges of a stimulus, such as corners or the ends of lines) in the primary visual cortex (area V1) and mid-temporal visual area (area MT, also known as area V5) respond differently from non-disrupted neurons to oscillating stimuli8-11. This differential response results in an apparent spatial mislocalization between the ends of a stimulus and its center, making a solid object appear as if it were bending at the center. (2008) In the visual system, observed objects may appear more salient or have greater contrast than unattended objects. This misdirection can be applied to the distraction of the attention of the viewer from the real image, making our brain perceive that a static image is moving. The concept of hidden misdirection is demonstrated by the cognitive neuroscience paradigm of changing contrast and color shades. People fail to notice that something is different than it was before. A recent study demonstrated that the illusion further supports the conclusion that location manipulation is not critical to effective covert misdirection.

The same thing happens in wild life when small animals try to camouflage themselves. “The principle of motion versus stationarity is related to the main type of camouflage that occurs when a prey animal remains motionless to avoid predators.”.
