3.2 Perception Flashcards
Definition of perception
The process of the brain analysing and making sense out of incoming sensory information
Areas of perception
- Segregation of objects
- Recognition of objects
- Judgment of distance
Definition of figure-ground phenomenon
The brain making sense out of the object’s shape and it appears to stand out from the background
The three visual cues
- Object is a meaningful object from memory (eg. Letters on a page)
- Figure is seen infront of the background
- Outline is seen to belong to the figure (edge assignment)
What visual cues help us to do
Differentiate between figure and ground
Definition of coherent pattern
The brain organising visual stimuli with simple additions and attractions or subtractions forming ordered relationships
Definition of binocular disparity
The brain merging the images produced from the left and right eye to allow us to make an accurate judgement of depth and distance
Three visual clues
- The relative size of the object
- If an object is superimposed over another object, it is deemed closer
- Relative height in field of view (closer the figure is to the horizon line, the further away it is seen to be)
What do visual clues allow us to do
Judge the distance of an object from us
Definition of perceptual constancy
The ability of our brains to recognise objects as unchanged despite visual stimuli changing (viewing angle, colour, distance, size)
Definition of recognition
The ability to identify and give meaning to an object
Most important factor in recognition
Shape (over detail)
Definition of inference
The brain recognising that an object is similar but not identical to one from past experience. The brain fills in the gaps and deduces that the object is related in some way to these visual images
Definition of perceptual set
Our readiness to percieve an object as we expect it to be as a result of expectations, past experiences or the object’s context.
The brain may ignore some sensory information to focus on others
