Definition
From the Environment. The ability to learn is inherited, but the behavior develops during an animals lifetime. variable&flexible
Term
Proximate Causes
Definition
immediate stimulus&mechanism;"how&what"
Term
Ultimate Causes

Sign Stimuli
Definition
triggers innate behaviors
Term
Fixed Action Pattern
Definition
an innate response that is always done the exact same way
Term
Imprinting
Definition
irreversible learning thats limited to a critical period in animals life;enhances fitness by enabling rapid learning
Term
Critical Period
Definition
sensitive phase for optimal imprinting
Term
Associative Learning
Definition
When an animal associates a stimuli to a reward or punishment
Term
Operant Conditioning
Definition
trial&error learning; associate behavior with reward or punishment, BF Skinner mouse box
