- internal EX: hunger
(3. mixture) EX: mating behavior
What is innate behavior?
-inborn, hereditary
What are 4 types of innate behaviors?
- reflexes
- taxes
- instincts
- FAPs
What is learned behavior?
depends on experience
What are 3 types of learned behaviors?
- imprinting
- habituation
- conditioning
What is a proximate cause?
- immediate cause of behavior
- immediate physiological response that leads to a behavior
What is an ultimate cause?
-adaptive value (evolutionary adaption
EX: bird migration
What is taxis?
- directional movment in response to a stimulus
positive: toward
negative: away
What is phototaxis?
light (planaria)
What is geotaxis? (or gravitaxis)
gravity (fruit flies)
What is rheotaxis?
against the current (salmon)
What are 4 other types of taxis?
- hydro
- thigmo
- chemo
- thermo
What is kinesis?
- non-directional, random movement
positive: increase in movement
negative: decrease in movement
What is hygrokinesis?
- a change in the rate of movement of an organism
- response to change in humidity

What is a threat?
intimidation
What is aggression?
force
What is submission?
retreat or avoidance
What is reproductive behavior?
- find a mate, courting, and mating
- species specific
What organism was used to text phototaxis?

What organism was used to test chemotaxis?
Paramecium caudatum (freshwater protist, ciliate)
Did planaria have a positive or negative phototaxis?
negative
