Perception Flashcards
Sensation
The stimulation of our sensory organs
Bottom-up processing
Learns data then forms a theory.
Sensory receptors work up to higher levels of processing
Top-down processing
Theory–> data
Sensory input by drawing from experience and expectations.
Transduction
Converting one form of energy into another that our brain can interpret
Psychophysics
Study of relationships between physical characteristics of stimuli ( intensity and psychological experience )
Absolute threshold
Minimum stimulation needed to detect stimuli 50% of the time
Subliminal
Stimuli you can not detect 50% of the time
Signal detection theory
Predicts when and how we detect a faint stimuli
Prime
Activation of associations unconsciously
Difference threshold
The difference detected between two stimuli 50% of the time
Weber’s law
To perceive a difference, two stimuli must differ at a constant proportion.
Light 8%
Objects 2%
Sensory adaptation
Constantly exposed to a stimulus that doesn’t change cause you to be less aware of it
Perceptual set
To perceive one thing and not another
Affect top-down processing
Expectations (top-down)
Context
Emotion and motivation
