Flashcards in Animal Behavior Deck (21):
1

Behavior

The way an organism responds to changes in its internal/external environment
Innate or learned

2

Ethology

Study of behavior & its relationship to its evolutionary origins

3

Fixed Action Pattern

Innate, highly stereotypical behavior that, once begun, is continued to completion no matter if it's useless/silly looking
Stickleback Fish

4

Sign Stimuli

Initiate a fixed action pattern

5

Releasers

Sign stimuli exchanged between members of the same species
Red belly on stickleback fish

6

Learning

Process in which the responses of the organisms are modified as a result of experience
3 types

7

Habituation

Simplest form of learning
Animals comes to ignore stimuli

8

Associative Learning

1 stimulus becomes linked to another through experience

9

Operant Conditioning

Associative Learning
Trial & Error Learning - animal associates its own behavior through reward/punishment
Rat in cage with lever

10

Classical Conditioning

Associative Learning
Ivan Pavlov, dog salivate when hearing bell - automatic response

11

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

12

Social Behavior

Any kind of interaction between 2/more animals, usually same species

13

Cooperation

Social Behavior
Enables individuals to carry out a behavior, like hunting, as a group = more successful

14

Agonistic Behavior

Social Behavior
Aggressive Behavior - Involves threats/actual combats of both real, ritualistic & symbolic aggressive behavior

15

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

16

Territoriality

Social Behavior
Territory = area an organism defends & from which other members of community are excluded

17

Altruism

Social Behavior
Behavior that reduces an individual's reproductive fitness (may die) while increasing fitness of group or family

18

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

19

Innate Behavior

Inborn
Running for shelter upon hearing loud noise

20

Learned Behavior

Child sharing toys with other

21

Stimulus

Change in environment
Hunger
