Sensation and perception
What is sensation?
Detection of sensory information and transferring that information to the nervous system
What is perception?
The process of organizing sensory information integrating past information and giving meaning to the information
Where does perception ultimately occur?
The brain
Can there be perception without sensation?
Yes, visual hallucinations and phantom limb syndrome are ways to perceive without sensation
Can the nervous system interact with the external world?

What is transduction?
The conversion of energy from one form to another
How does the sensory system interact with the nervous system?
Senses detect and respond to the world, convert it by communicating with sensory neurons, send the neural signal to the brain first going to the thalamus (except smell) and then are sent to the sensory cortex areas
What is bottom up processing?
Working with small, individual pieces of information to get to the larger pictures
What is top down processing?
You have an expectation based on past experience and you use it to organize the information you are working with
When can top down processing be used?
When we have memories of past experiences that can be reasonably applied to our present experience
Is Sensation or Perception Bottom-Up?
Sensation is more of a bottom-up process and perception is more of a top-down process
Are the processes just implicit or explicit?
Whether a process is top-down or bottom-up does not determine if it is explicit or implicit
What is the downside to top-down processing?
Humans are biased to interpret the world in a manner that conforms with their beliefs
