UNIT 4 Flashcards
Sensation and perception
Sensation and perception are about how we notice and understand things around us using our senses.
-The process of sensation and perception take place within one unified information-processing system
Sensation
Sensation how when we notice things happening inside and outside our bodies using our senses.
-Its a physiological process
Stimuli
Physical inputs or energy we receive through our five senses
Perception
a psychological process where our brain helps us choose, analyse, organize, and understand the things we sense.
Visual Perception
How our mind makes sense of what we see based on our unique background and experiences
Perceptual laws and factors which determine perceptual organisation
These are rules that help our brain organize what we see:
-Form perception
-Depth and spatial perception
-Perceptual constancy
-Perception of movement
-Visual or perceptual illusions
Form Perception
This is how our brain makes sense of what we see by organizing visual elements into meaningful patterns or groups.
Gestalt principle of wholeness
Asserts that ‘The whole is more than the sum of the parts’
Psychological factors in visual perception
-Hues: Colour names and related to wavelengths
-Saturation: Intensity of light and purity of complexity of lightwaves
-Brightness: The amount of light reflected on an object
Gestalt laws of visual perception
-Law of Similarity
-Law of Proximity
-Law of Closure
-Law of Prägnanz (Simplicity)
-Law of Common Fate
-Law of symmetry
-Law of continuity
Law of Similarity
We perceive similar items as belonging together.
Law of Proximity:
Objects that are close to each other are perceived as a group
Law of Continuity:
We prefer continuous, smooth lines and patterns. Our brain follows the simplest path when connecting points
Law of Closure
Viewers tend to fill in gaps to see complete shapes even if part of an object is missing
Law of Prägnanz (Simplicity)
Views tend to perceive complex elements in the simplest form possible.
