- Topic A- How we see, Depth cues and Gestalt laws
- Perception- brain correctly interpreting what the eyes see
- Structure Of The Eye
- Pupil- allows light to enter the eye
- Retina- Light sensitive layer of eye, contains rod+ cone cells
- Rod Cells- sensitive to light and detect movement- found in edges of retina
- Cone Cells- only work in intense light and detect colour- found in centre of retina
- Optic Nerve- transmits impulses to brain from retina at back of eye
- Neural Impulses- electrical signals along dendrites to produce nerve impulse or action
- Visual Cortex- part of cerebral cortex that receives and processes sensory nerve impulses from eyes
- Optic Chiasma- where optic nerves from both eyes meet each other
- Neural Impulses- electrical signals along dendrites to produce nerve impulse or action
- Depth Cues
- Monocular Depth Cues- only need one eye
- Relative Size- allows you to determine how close objects are to an object of known size
- Texture Gradient- change in appearance of objects from coarse to fine - detailed- closer and less distinct- further away
- Height In The Plane- objects that are far away from the horizon are perceived as farther away
- Super Imposition- object that covers another is closer
- Linear Perspective- two identical items appear to vary in size with amount of distance involved and why roads appear to narrow with distance
- Binocular Depth Cues- depth perception requires both eyes
- Stereopsis- our eyes are located beside each other, because of this each eyes view of a scene is slightly different. These two pictures, are sent to brain and fused to create three-dimensional picture
- Dominant Eye- tendency to prefer visual input from one eye to the other
- Stereopsis- our eyes are located beside each other, because of this each eyes view of a scene is slightly different. These two pictures, are sent to brain and fused to create three-dimensional picture
- Monocular Depth Cues- only need one eye
- Size Constancy- perceive an object as being same size regardless of how close or far away it is
- Gesalt Law- object, idea, or experience as being more than the sum of its parts. When you put the parts together, you get the whole
- Gesalt- good form
- Figure Ground- separating a figure from a back ground
- Similarity- group together objects or stimuli that seem similar to each other
- Proximity- Proximity means closeness, group things that are close together
- Continuity- create continuous patterns and perceive connected objects as uninterrupted
- Closure- fill in visual gaps in order to perceive disconnected parts as a whole object
