All Flashcards
What is sensation?
The process where sensory receptors receive stimulus energies.
What is perception?
The process of organizing and interpreting sensory information.
What is sensory adaptation?
Decreasing responsiveness to a stimulus due to constant stimulation.
What is sensory habituation?
Perception of sensation depends on how much you focus on it.
What is Gestalt?
The idea that we organize sensations into a whole or form.
What is sensory transduction?
Converting one form of energy into another for neural impulses.
What is absolute threshold?
Minimum stimulation needed to detect a stimulus 50% of the time.
What are subliminal stimuli?
Stimuli below your absolute threshold that you're not consciously aware of.
What is difference threshold (JND)?
Minimum difference between two stimuli required for detection 50% of the time.
What is Weber's Law?
To perceive a difference, two stimuli must differ by a constant percentage.
Give an example of sensory adaptation.
Not feeling your socks after wearing them for a while.
Give an example of sensory habituation.
Not noticing the ticking of a clock until you pay attention to it.
How does top-down processing affect taste perception?
Expectations about food can influence how it tastes.
How is the Figure-Ground relationship used in art?
Artists use it to create depth and focus in their work.
How can sensory adaptation affect your experience in a new environment?
Initially strong smells or sounds become less noticeable over time.
How does Weber's Law apply to marketing?
Price increases need to be significant enough to be noticed by consumers.
How does sensory adaptation help us focus?
By filtering out constant, unchanging stimuli, we can focus on changes in our surroundings.
Compare sensation and perception.
Sensation is raw data collection; perception is interpreting that data.
Compare bottom-up and top-down processing.
Bottom-up starts with sensory input; top-down uses prior knowledge.
Compare sensory adaptation and sensory habituation.
Adaptation is a physical process; habituation is a cognitive one.
