Human nervous system.
Child development.
Human communication.
Natural selection.
3. Animal Behavior Behavior- a way an organism responds to stimuli in its environment.
Two Parts:
The How?- hormone levels, nerve impulses and pathways-Proximate Causation.
The Why?- adaptive value to animal’s survival or reproductive success- Ultimate Causation.
4. What’s the difference between stimulus and response? Stimulus- some environmental change or factor that can be perceived by a sense.
Response- an organism’s reaction to an environmental change.
5. Ethology Study of natural history of behavior.
Early ethologist, like Konrad Lorenz and Niko Tinbergen, believed behavior was based on instinct- innate.
Example: Egg Retrieval in Geese
Insect--> Frog’s Tongue
6. Viewed Behavior in 3 Parts Sign Stimulus- appearance of some signal.
Innate Releasing Mechanism- sensory mechanism that detects the signal.
Fixed Action Pattern- stereotyped act or behavior.
