Behavior Behavior A behavior is anything
an organism does in response to a stimulus in its environment.
A behavior is anything an organism does in response to a stimulus in its environment.
Brainpop- Behavior
Behavior Behavior A stimulus is any kind of
signal (chemical or physical) that can be detected by an organism; a response is the organism’s reaction to the stimulus.
Ex . Lowered blood sugar causes a release in insulin which triggers a feeling of hunger.

Behavior Behavior Behaviors have evolved as
a result of natural selection.
A behavior that is beneficial to an organism has adaptive value - it allows the organism to survive and reproduce better than those organisms that do NOT display this behavior

Simple instincts include “suckling”, allowing animals to be able to feed right after birth.
Other instincts are more complex; these behaviors may be classified as one of the following:

present mostly in animals with a more highly developed nervous system.
Learning requires motivation - an internal need that causes an animal to act (i.e. hunger)

Types of learning:Types of learning: Habituation - occurs
when an animal is repeatedly given a stimulus with no punishment or reward; eventually the animal stops responding
Ex. You are able to sleep through the night even though you live close to the train tracks.

occurs when an animal learns to behave a certain way through repeated practice, in order to receive a reward or avoid punishment; also called “trial-and-error”
