1. What is a percept? (1)
A percept is the mental representation of actually seeing an object that is perceived through the senses, although the object is seen in two dimension by the proximal stimulus the visual system converts this into a three dimensional percept.
2. What is another name for the retinal image? (1)
Another name for retina image is proximal stimulus.
3. This picture is called Leeper’s lady. It is an example of an ambiguous figure.
Using the picture as an example, explain what is meant by an ambiguous figure. (2)
The term ambiguous figure refers to an image that can be perceived in more than one way. This perception of the image appears to flip between the two alternative images; one interpretation of the image will completely exclude the other image while it persists.
In the example of the Leepers Lady you can see either an image of a young lady or an old woman; although both perceptions are there you can only see one of the interpretations at any time, so while viewing the image as the picture of the old women you cannot see the image of the young lady.
4. What do ambiguous figures tell us about visual perception, according to Gregory? (4)
According to Richard Gregory ambiguous figures tell us that our visual perceptions can form more than one percept from a single image, which shows us that it requires more than just sensory input to be able to see alternative precepts. When the brain develops two plausible hypotheses for a single image, the image will flip between the two perceptions as the brain is unable to decide them
Richard Gregory believed that perception is an active constructive process which relies on top-down processing as well as the visual system receiving input from sensory receptors. When we look at an image we interpret it using cognitive knowledge primary based on prior knowledge and previous experience not just by the image captured by the proximal stimulus, therefore using knowledge and external...
