Module 17 Flashcards
What is sensation?
The brain recieving input from sensory organs
What is perception?
The processing of information from your sensory organs
What is bottom-up processing? Top-down processing?
Bottom-up is taking sensory input and then assembling (what am I seeing?) Top-down is using models to interpret sensory information (Is that something I’ve seen before?)
What are the 3 steps in the process of sensation?
Reception, transduction, transmission
What is Reception?
The stimulation of sensory receptor cells
What is transduction?
Transforming the stimulation into neural impulses
What is transmission?
Delivering this neural information to the brain to be processed
What is absolute threshold and what does it depend on?
The minimum level of stimulus intensity needed to detect a stimulus 50% of the time. This depends on psychological factors
What is priming?
When exposure to one stimulus influences the response to another stimulus
What is sensory adaptation?
Tuning out a constant stimulus
What is perceptual set?
What we expect to see which influences what we do see
