Form Perception Flashcards
Bottom-up Processing
our interpretation of a stimulus emerges from the data, the actual physical properties of the stimulus
Carpentered world hypothesis
Our experience of living in a world of human -made objects with right angles helps drive the Muller-Lyer illusion
Complex cells
Cells located in the visual cortex that respond to the orientation of a bar of light as well as the direction of its movement
Exemplar theory
Proposes that objects in the environment are compared to copies (exemplars) stored in memory
Geon
A series of 3 dimensional shapes; recognition-by-components theory proposes that the world can be made up from 36 geons
Gestalt psychology
Proposes we use 6 basic principles to interpret the world
Hypercomplex cells
Cells in the visual cortex that have all the features of complex cells but are also sensitive to the length of the bar of light
Muller-Lyer illusion
Where two identical lines are made to look like they are different lengths by the placement of arrows on the ends
Orientation columns
Stripes of neurons in the visual cortex that respond preferentially to stimuli of a specific angle
Perceptual constancy
We see familiar objects as having standard size, shape,colour, or location regardless of change in angle of perspective, distance, or lighting
Prototype model
Proposes that new stimuli are compared with an average stored in memory
Recognition-by-components
Proposes that all objects can be made through combining 36 geons
Simple cells
Cells located in the visual cortex that respond to the orientation of bars of light
Top-down processing
Higher-level cognitive process, such as our knowledge/experience influence the interpretation of a stimulus
