Behavior biology
Term
Genes and experience
Definition
-Animals are genetically programed to perform certain behaviors
- Love bird nest making
Term
Genes
Definition
Rigid and can not be changed
Term
Experience
Definition
-Behaviors changed by experiences
-Genes change for current conditions based in
-"Nature vs. Nurture"= gene vs. experience
Term
Innate behavior
Definition
-Behaviors b/c of genetics
-Often have to do with survival or reproduction
-Fixed action Patterns (FAP's)
-Sign stimulus
Term
Sign stimulus
Definition
a stimulus that causes a FAP
Term
Fixed Action Patterns (FAP)
Definition
-an unchanging behavioral sequence which must be done in its entirety
-Innate response to certain stimulus
-Allow the young to get a good chance
-Evolution has made it through once reproduction is successful, survival has a better chance
-Cannot be modified no matter what
-Ex: Goose and European Cuckoo
Term
learning
Definition
-A change in behavior based on an experience
Term
habituation
Definition
-A loss of response to a stimulus after repeated negative exposure
-an animal learns not to respond to an unimportant stimulus
-prevents an animal from engaging in a useless activity; good b/c it save energy
-Ex: Scare crow
Term
Imprinting
Definition
-Learning that has been genetically limited to a specific time period
-Once it is set, it can not be changed
-Time period in which this occurs is called the critical period
-Ex: Baby goose
Term
Association/ Classical conditioning
Definition
-learning based in positive or negative reinforcement; positive reinforcement works better
-Negative reinforcement (porcupine or skunk)
-Ex: Dog
Term
Imitation
Definition
-Mimicking behavior of parents
-Trial and error for success
-Ex: hunting or pouncing (by all cats)
Term
Innovation aka insight
Definition
-True problem solving
-Ability to perform correct behavior on first attempt with prior experience
-Implies an ability to think (ah ha moment)
-Different types of other learning go into this
-Ex: Human beings and apes/monkeys
Term
Behavior
Definition
-Simply an adaptation that enhances survival
- reproduce more
-Learn;stay alive; reproduce more; survive
-Fine tunes an organism for real world
Term
Animal migration
Definition
-Regular movement of bunch of animals from one place to another at various times during the year
Term
Reasons for migration

-need to know what they are chasing
-key in on one image of food in their head so they know what to go after
Term
Optimal foraging
Definition
-Want to get most calories for energy spent
-Jaguars and the armadillos
Term
Handling time
Definition
-Time to chase, pounce, kill, and devour food)
- Want the shortest handling time
Term
Social behavior
Definition
- Any interaction between 2 or more animals (usually of same species
-Very important in terms of reproduction and getting along with other members of the group
Term
Agonistic behavior
Definition
-Threats or fighting settle a dispute that arises
