The study of the biological and evolutionary bases for behavior, drawing on ethology and comparative psychology
Ethology
Basic biology field focusing on the behaviors of diverese organisms in their natural environments
Comparative psychology
Extension of human psychology, but focusing largely on experiments done in a few species of lab animals
4 main questions to understand a behavior:
What causes the behavior (socially and biologically)
How does the behavior develop (when in life, what stage you have to reach)
How does the behavior affect fitness (up chances of survival and reproduction)
How did the behavior evolve (how does it compare to other species, what might have caused its evolution)
Hibernation
When an animal goes into a den or burrow, reduces metabolic rate, and stays in a state of inactivity over the winter
Estivation
Hibernation but during the summer, usually happens in desert species
Migration
Behavior when animals move from one location to another in a seasonal pattern
Circadian rhythm
Internal body clock of an animal that dictates their sleep schedule based on the day/night cycle
Innate behaviors
Behaviors that are hardwired and are inherited by on organism from its parents
Learned behaviors
Behaviors that are not inherited but developed throughout an organism's lifetime as a result of experience and environment
Reflex actions
Very simple innate behaviors that happen independently from the brain in response to stimuli, like pulling away your hand from a hot surface
Kinesis
Innate behaviors in which organisms change their movements in a non-directional way (so like slowing down or speeding up) in response to a cue or stimulus like temperature or smells
Taxis
Innate reflex movement towards or away from a stimulus like light, sound, or smells
Fixed action pattern
Predictable series of actions triggered by a cue (key stimulus) that is automatic and involuntary, even if it's more complicated, and will be completed even if the stimulus is removed (egg retrieval, spot pecking)
Habituation
Simple learned behavior where an animal gradually stops responding to a repeated stimulus
Imprinting
Highly specific learned behavior where newborn animals become extremely attached to the first animal they see, usually their mother (like where duckings follow their mothers)
Classical conditioning
Learned behavior where a reaction already associated with a stimulus is linked to another stimulus, like ringing a bell when you get food makes you eventually salivate when you hear the bell
Unconditioned
Adjective for the stimulus and reaction that occur together innately without classical conditioning, like when a dog salivates when presented with food
Operant conditoning
Rewarding or punishing an animal to get it to do a behavior more or less often
Communication
When one animal transmits information to another animal causing some sort of change in the animal receiving it
Pheromone
Secreted chemical signal used to trigger a response in another individual of the same species, especially common among social insects. Could attract a member of the opposite sex, mark a food trail, or raise an alarm
