Habituation
Captions available
The idea
Habituation is a simple form of learning in which an animal's response to a repeated, harmless stimulus weakens over time.
In practice
A prairie dog stops giving alarm calls at a scarecrow after repeated exposure shows it poses no threat.
Where people slip
Habituation is a decreased response to one specific stimulus, not general fatigue affecting all responses.
