Sensation and Perception
• Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
• Perception is the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.

Are the disks moving?

Are the Disks Moving? (ctd.)
• Perception of movement
• A question to ponder: Is perception reality?
• If the disks are not moving, why do we think they are?
• Is there knowledge in deception?
• What sort of questions should you ask before you decide something is true?

Why Do People Wear Labels?
• How information is presented affects how we perceive.

• The brain is imposing meaning on something that is inherently meaningless.

How Many F’s Can You Count?
• Instructions: Count only once – don’t go back!!
• Finished files are the result of years of scientific study combined with the experience of years.

Results• If you counted…
6 = You are a genius!
5 = You are pretty darn smart.
4 = You are above average.
3 = You are of average intelligence.
• Most people overlook “of” words – the human brain tends to process them as v’s.

Paradigms
• There is too much sensory information!!• A paradigm is a way of organizing and condensing
sensory information.• A paradigm is a set of unwritten rules and
regulations that:– Establish and define boundaries.– Tell us how to behave inside boundaries in order to be
successful.
• Paradigms may be personal, political, or cultural.• Paradigms are contextually based.

Paradigms (ctd.)
Time flies like an arrow.
Fruit flies like a banana.
-Groucho Marx
• What’s funny about this? Why doesn’t it make sense at first?
• Examples of paradigms: breakfast food, history, science, rap music.

One Picture – Many Perspectives
![Page 20: Sensation and Perception Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment](https://reader035.vdocuments.site/reader035/viewer/2022062809/5697bf761a28abf838c80f13/html5/thumbnails/20.jpg)
One Picture – Many Perspectives
• Writing Assignment: Based on the previous photo of the girl jumping onto a pile of leaves …– Write a paragraph celebrating the joys of
childhood.– Write a paragraph warning parents of the
dangers of “leaf-jumping.”– Develop an outline for a fairy tale.– Write an ad for Tide laundry detergent.

Concluding Thoughts
• What we experience is not simply the “world out there” as it is.
• Human experience is the product of– The external world– The physical environment– Personal ideas and values
• What about bias?– If everything is biased, then nothing is biased.

Final Questions
• How, if at all, can the influences of our biases be overcome?
• Do perceptions perform different functions in different AoK’s?
• What are the obstacles to perception and how might they be overcome?
