CMN 122 Lecture Notes - Lecture 15: Bombykol, Cleaner Fish, Animal Communication
Document Summary
A"s behavior manipulates b"s sense organs in such a way that b"s behavior has changed. Ways to assign meaning to an animal signal. Look at the state of the signaling animal. Observe the response of the receiving individuals. 12 owners of mudies, 12 owners of other breeds, 12 who did not own a dog. All participants could correctly classify the barks. Dog barks contain info about their emotional state that is easily decoded by all humans. Some receivers are highly sensitive (e. g. , female silk moth and bombykol) Bombykol is a pheromone detected by male moths causing their wings to flutter. Sound signals can varies in pitch, loudness, frequency, and temporal (how long the sound made lasts) pattern. Most vertebrates modulate temporal patterning and frequency-- pitch and loudness are mostly constant. Sound producing qualities can be artificially expanded. Ex. loudness can be expanded using a device (mega-phone) Mole cricket uses a burrow to magnify/ artificially expand its sound.
