Visual Perception Chapter 3
Sensation & Perception Sensation: Occurs when our sensors (internal & external) detect & respond to information. Perception: assigning meaning to the information that we sense. This occurs in the brain and is a personal interpretation. When you view the next 3 images, your eyes will gather information, then you brain will select certain parts of that information, organise the parts and finally interpret and evaluate them.

Reception, Transduction, Transmission Reception: photoreceptors (rods & cones) in the retina detect light stimulus Transduction: Light energy (EM) is converted into electrochemical energy Transmission: Electrical message is sent to the visual cortex in the brain via the optic nerve.

Perception: Gestalt principles Gestalt – the way we organise parts into a whole We mentally ‘fill in’ the parts that we can’t see. 1. figure-ground organisation Object is the figure, everything else is background Needs a line or boundary (contour) Contour is part of the object
Perception: Gestalt principles 2. Closure tendency to mentally fill in or ignore gaps in the object 3. Similarity Tendency to group similar features together
Perception: Depth principles 4. Proximity tendency to perceive parts that are close together as belonging together.
Perception: Depth principles Ability to accurately estimate the distance of an object (can see 3 -D) 1. Binocular (requires both eyes) Convergence Retinal disparity
Perception: Depth principles Ability to accurately estimate the distance of an object (can see 3 D) 2. Monocular (requires only one eye) Accommodation Pictorial Cues linear perspective interposition texture gradient relative size height in the visual field
Perception: Perceptual constancies 3. Perceptual Constancies shape constancy size constancy brightness constancy
