Adaptation Flashcards
Adaptation is the decrease in sensory receptor (PNS) sensitivity during what?
A LONG-LASTING STIMULUS
What are receptors which continue to respond throughout the duration of a prolonged stimulus termed?
SLOW ADAPTING
ie - NOCICEPTORS (PAIN)
Name the receptors that respond best to change?
FAST ACTING RECEPTORS
ie - OLFACTORY RECEPTORS (SMELL)
Name the term for the smallest amount you can just sense “something about half of the time”?
ie - barely hear a sound
ABSOLUTE THRESHOLD
Name the term for the smallest amount of change needed in a stimulus before we notice the change?
DIFFERENCE THRESHOLD
What is the law which states that the change needed to notice a difference between two stimuli is proportional to the original intensity of the stimulus?
WEBER’S LAW
Applying Weber’s Law to weight, the proportion is a ______% increase.
10

5
