Context Effect A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus.
Schema In psychology and cognitive science, a schema describes a pattern of thought or behavior that organizes categories of information and the relationships among them.
Selective Attention What you are paying attention to is what you will see.
After Image An impression of a vivid sensation retained after the stimulus has ceased.
Sensory Adaptation A reduction in sensitivity to a stimulus after constant exposure to it. Sensory adaptation reduces our awareness of a constant stimulus, but it helps free up our attention and resources to attend to other stimuli in the environment around us.
Signal Detection Theory Whether or not we detect a stimulus (especially against background noise) depends on signal intensity and the person's individual experience, expectations, motivations, or alertness.
Subliminal Detection Although we can not learn complex knowledge from subliminal stimuli, we can be primed, and this will affect our choices.
Color Constancy We see consistent colors, even in changing illumination, our brains can compensate for the shading. Context will change our perception of color.
Linear Perspective A system of creating an illusion of depth on a flat surface. All parallel lines in a painting or drawing using this system converge in a single vanishing point on the composition's horizon line.
Interposition When an object appears to block the view of another, we assume that the blocking object is in a specific position relative to distance.
