Psychology- perception Flashcards
What is it meant by the term perception?
The way sensory information is organised, interpreted, and consciously experienced.
What is meant by the term sensation?
The information we receive through our senses.
What is meant by the term binocular depth cue?
The images taken in by both eyes to give depth perception, or stereopsis.
One type of monocular depth cue is height in plane. Explain.
How things that are further away often appear to be positioned higher up.
What is meant by the term monocular depth cue?
The information in the retinal image that gives us information about depth and distance
One type of monocular depth cue is relative size. Explain.
Gives you the ability to measure how far away something is.
One type of monocular depth cue is occlusion. Explain.
Occlusion is a monocular depth cue produced by partially overlapping objects.
One type of monocular depth cue is linear perspective. Explain.
Linear perspective is a monocular cue because the effects are manifested as actual differences in distance and size that require only a single eye to perceive.
Outline how retinal disparity and convergence are used to perceive distance and depth.
The brain uses retinal disparity to estimate the distance between the viewer and the object being viewed.
What is meant by the term size consistency?
a property that guarantees the consistency of the energy behaviour when interaction between the involved molecular system is nullified
What is meant by the term misinterpreted depth cues?
objects apparently in the distance. scaled up by the brain to look normal size, cause visual illusions.
What is meant by the term monocular fiction?
When your brain thinks there something there when there actually isn’t.
What is meant by the term monocular ambiguity?
perceived in multiple ways.
The Muller-Lyer visual illusion is an example of misinterpreted depth cues. Explain how misinterpreted depth cues cause this visual illusion.
The Ponzo visual illusion is an example of size consistency. Explain how size consistency cause this visual illusion.
The Kanizsa triangle visual illusion is an example of fiction. Explain how fiction causes this visual illusion.
Explain the role of motion parallax in everyday perception.
Provides a powerful cue to three-dimensional scene structure.
Explain the role of optic flow patterns in perception.
plays an important role in the perception of the shape of objects and the layout of the environment
Describe one strength of Gibsons constructivist theory of perception
it was developed using research with pilots in the real world.
Describe one weakness of Gibson’s constructivist theory of perception
cannot explain why perceptions are sometimes inaccurate, e.g. in illusions.
What is Gregory’s belief about perception?
This view states that perception depends on making inferences based on past experiences.
Explain what is meant by inference and how it affects perception.
A phenomenon in which mental processing is made slower and less accurate by competing mental processes
Explain what is meant by visual cues and how it affects perception.
Sensory cues received by the eye in the form of light and processed by the visual system during visual perception
