are illusions top down processing?

The experience of visual illusions, for example, can illustrate how bottom-up and top-down processes influence how we experience the world. ... However, because our brains are predisposed to perceive faces and because of top-down processes, we are likely to begin to see a human face in these ambiguous shapes.

Bottom-up processing refers to processing sensory information as it is coming in. In other words, if I flash a random picture on the screen, your eyes detect the features, your brain pieces it together, and you perceive a picture of an eagle.

What is the difference between indirect perception checking and direct perception checking? ... Indirect perception checking does not involve asking questions; direct perception checking requires you to ask questions to clarify your perceptions. Describe a situation in which you have used direct perception checking.

The human eye can process up to 10-12 images per second and perceive the pictures being shown individually. When this rate goes up the person will perceive it as motion. Scientists and researchers working on this topic believe that the human brain perceives reality at a rate somewhere between 24 – 48 fps.

Perception occurs in five stages: stimulation, organization, interpretation-evaluation, memory and recall. People studied perception as the need to solve a particular problems, arise simply from intellectual curiosity about themselves and the world.

No. If you wear the 3D glasses the images will appear to come at you or your lap. ... But if you look at the same screen without the 3D glasses the images will make you feel like you are seeing double -overlapping images. However often an IMAX movie available in 3D and also without 3D.

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.

For the clearest evidence of Bayesian reasoning in the brain, we must look past the high‐level cognitive processes that govern how we think and assess evidence, and consider the unconscious processes that control perception and movement. ... “We really are Bayesian inference machines,” he says.

Because of the Gestalt law of continuity, you perceived the two disconnected shapes as one continuous object, which your brain then interpreted as a moose. It is important to remember that while these principles are referred to as laws of perceptual organization, they are actually heuristics or short-cuts.

"Three areas of the brain generally become more active during deception: the anterior cingulated cortex, the dorsal lateral prefrontal cortex and the parietal cortex." The anterior cingulated cortex is thought to be in charge of monitoring errors.

A study carried out by Schlaffke et al. reported that individuals who saw the dress as white and gold showed increased activity in the frontal and parietal regions of the brain. These areas are thought to be critical in higher cognition activities.

Here, we argue that the actual temporal resolution of conventional (scalp potentials) EEG is overestimated, and that volume conduction, the main cause of the poor spatial resolution of EEG, also distorts the recovered time course of the underlying sources at scalp level, and hence degrades the actual temporal ...

Top-down learning refers to learning explicit knowledge first and then learning implicit knowledge on that basis (i.e., assimilating explicit knowledge into an implicit form).
