What is sensation?
process of detecting, converting and transmitting raw sensory info from external and internal environemnts to the brain
process of gathering information from people to send to other people
sensory nerve ending that respond to sitimuli
sensory nerve ending that respond to stimuli
Sensory Neurons
Sensory Receptors
What is perception
Perception is the process of selecting, organizing, and interpreting sensory information.
Does perceptual set involve bottom up or top down processing? Why?
Top-down processing because it involves using expectations and prior experience to make sense of/process information
Random processing because it involves using expectations and prior experience to make sense of/process information
Bottom-up processing because it involves using expectations and prior experience to make sense of/process information
What is perceptual set?
Perceptual set is a mental predisposition to perceive one thing and not another
What is sensory adaptation? What is the function of sensory adaptation?
Sensory adaptation is when constantly exposed to an unchanging stimulus we become less aware of it because our nerve cells fire less frequently
______________ is when constantly exposed to an unchanging stimulus we become less aware of it because our nerve cells fire less frequently
Sensory adaptation
Perceptual Set
What do we call the process of converting one form of energy into another form that our brain can use?
Transduction is _______
the process of converting one form of energy into another form our brain can use
absolute threshold
The minimum stimulus energy needed to detect a particular stimuli
The minimum stimulus energy needed to detect a particular stimuli
the minimum difference between 2 stimuli required for detection
Difference Threshold
If you can tell the difference between 2 smells/sights/sounds/touches/tastes
it has crossed your ______ threshold
absolute
If you can hear/see/taste/feel/smell/something
it has crossed your ______ threshold
absolute
difference
What are the 3 steps that are basic to all our sensory systems?
Sensory receptors (eyes, ears, nose, tongue, skin) neural impulses, brain (visual, olfactory, etc...)
Why is it that after wearing shoes for a while, you cease to notice them (until questions like this draw your attention back to them?
You stop noticing shoes due to perceptual set. Your senses have adapted to the feeling, and you can now focus on new sensory information
You stop noticing shoes due to sensory adaptation. Your senses have adapted to the feeling, and you can now focus on new sensory information
______ _____ processing is when analysis that begins with the sensory receptors and works up to brain integration of sensory information
______ _____ processing is when processing guided by higher level mental processes as when we construct perception based on prior experience and expectations
When you dont know what something is, you use your senses to gather up info until you come up with the big picture. Example... lights go out in the middle of the night and you feel around until you find the light.
What type of processing is this?
When your prior experience influences your thinking. You watch a movie about robbers, you hear wind outside, and then you think there are robber outside, you think/look deeper and find out its just the wind.
What type of processing is this?
