• Ethology is the study
of Behavioral Biology

• Ethology~ study of animal behavior. (Aggregate of all responses,
movements and reactions in an organism)
• Ultimate cause of behaviors is????
• 5 Main types of classified behaviors studied most often:
• TYPE 1 (Innate or instinctual) behaviors include (There are 4 sub
categories here):
– A) Sign Stimulus Behaviors~ external sensory stimulus causes an
unchangeable response. Known as fixed action patterns. (FAP)
– B) Imprinting Behaviors~ during a critical period, the young identify
and respond to specific stimulus.
– C) Reflex Behaviors~ automatic behaviors
– D) Orientation Behaviors- kinesis=random movement,
taxis=purposeful towards or away from stimuli and migration

TYPE 2 Behaviors that occur as a result of Learning. (Learned
behaviors)
These behaviors can be affected by;
Maturation-behavior increase due to developing physiological ability. (Brain
development) AND/OR
Habituation~ behavior decrease due to loss of responsiveness to stimuli that
convey no information.
• There are two sub categories again here of Type 2 behaviors;
• A) Abstract learning: complex, higher order learned behaviors based on
reasoning (insight learning)
• B) Associative learning:
•classical conditioning~ Pavlov’s dogs
•operant conditioning (trial and error)~ “Skinner’s box”

TYPE 3 ~ Social behaviors:
There are 3 main categories:
• Agonistic behavior~ contest behaviors
determining access to resources,
submission/aggression
• Dominance hierarchy behavior ~
“pecking order”, alpha males and females
• Territoriality behavior~ an area an
individual defends excluding others
• The Mating system drives social
behaviors:
• •promiscuous~ no strong pair bonds
• •monogamous~ one male/one female
• polygyny~ one male/many females
polyandry~ one female/many males

Type 4 ~Non-mating behaviors
• Migration
• Hunting
• Safety

Type 5 ~Altruistic behavior• Altruism~ a behavior that
results in the survival of someone
else
• Coefficient of
relatedness~ proportion of
genes that are identical because
of common ancestors, more
closely related you are the more
altruistic you are
• Reciprocal altruism~ Done
in the hopes of exchange of aid
• Cooperation!

• Human exclusive
behaviors?

Science currently tells us
• It’s our greater ability to form and recognize
relationships (most complex social
networks in the animal kingdom) ,and the
practice of true teaching that has given us
a huge cooperative advantage!
• Why those 2 things?

Encephalic quotient
• Brain mass to lean
muscle mass
• More dynamic
social
settings=increase
neural plasticity

How is “intelligence” measured?
• Ability to not repeat errors
• Build on existing idea
• Predict & Analyze
• Control or change surroundings
• Ask “why?”
• Symbiosis and human intelligence?
• Domestication of the dog
