Animal Behavior Flashcards
Behavior
The way an organism responds to changes in its internal/external environment
Innate or learned
Ethology
Study of behavior & its relationship to its evolutionary origins
Fixed Action Pattern
Innate, highly stereotypical behavior that, once begun, is continued to completion no matter if it’s useless/silly looking
Stickleback Fish
Sign Stimuli
Initiate a fixed action pattern
Releasers
Sign stimuli exchanged between members of the same species

Learning
Process in which the responses of the organisms are modified as a result of experience
3 types
Habituation
Simplest form of learning
Animals comes to ignore stimuli
Associative Learning
1 stimulus becomes linked to another through experience
Operant Conditioning
Associative Learning
Trial & Error Learning - animal associates its own behavior through reward/punishment
Rat in cage with lever
Classical Conditioning
Associative Learning
Ivan Pavlov, dog salivate when hearing bell - automatic response
Imprinting
Learning that occurs early in life, irreversible during that time
Mother-offspring bonding, if it fails parent will not care for offspring & offspring will die
Social Behavior
Any kind of interaction between 2/more animals, usually same species
Cooperation
Social Behavior
Enables individuals to carry out a behavior, like hunting, as a group = more successful
Agonistic Behavior
Social Behavior
Aggressive Behavior - Involves threats/actual combats of both real, ritualistic & symbolic aggressive behavior
Dominance Hierarchies
Social Behavior
Pecking order behaviors that dictate the social position of animal in a culture
Ex: Hens, alpha controls all, beta all but alpha, & so on
Territoriality
Social Behavior
Territory = area an organism defends & from which other members of community are excluded
Altruism
Social Behavior
Behavior that reduces an individual’s reproductive fitness (may die) while increasing fitness of group or family
Kin Selection
Altruism, Social Behavior
When an individual sacrifices itself for the family, it is sacrificing itself for relatives (kin), which share similar genes
Kin selected (saved) can pass on their genes
Innate Behavior
Inborn
Running for shelter upon hearing loud noise
Learned Behavior
Child sharing toys with other
Stimulus
Change in environment
Hunger
