In psychology, a ''Gestalt Switch'' is when a person's perception suddenly changes from one visual interpretation to another. For instance, the initial interpretation of '''Figure 1''' is usually a face, however, given time, people can also see an eskimo. The reason the majority of people initially see a face first is that this is a prioritised type of human perception. It has been found that there are inbuilt mechanisms in the brain which canalize ambiguous information into the face processing part of the brain. | In psychology, a ''Gestalt Switch'' is when a person's perception suddenly changes from one visual interpretation to another.

It has been found that there are inbuilt mechanisms in the brain which canalize ambiguous information into the face processing part of the brain. Another demonstration of this is the [[Coffer Ambiguous Figure]] which takes advantage of the brain prioritisation of horizontal lines over rounded lines. | ||

Gestalt Switches can be [[Framing|framed]] or [[priming|primed]] so that the presenter can force others to seeing one version of the image opposed to another. For instance, if you take '''Figure 1''' and present it to someone else with the framing: ''"here is a a picture of an eskimo entering a cave"'' you will be able to force their perception into primarily seeing the eskimo. | Gestalt Switches can be [[Framing|framed]] or [[priming|primed]] so that the presenter can force others to seeing one version of the image opposed to another.
