AIM: Describe instinctive and learned behaviors as
well as patterns of behavior in animals?
OBJ: Given notes and activity sheet SWBAT
describe types and patterns of behavior in animals
with 70% accuracy
DN: Copy notes
ACT: Introduction to behavior / patterns of behavior
(notes)
HW: Text, read p.149-154 and p.157-163;
Complete What is Behavior? Activity Sheet;
Vertebrate Exam, this Wednesday, Dec. 3
Lesson Notes
Stimulus: a signal that causes an organism
to react in some way.
Response: an organism’s reaction to a
stimulus. (All animal behaviors are caused
by stimuli)
Function of Behavior: survival and
reproduction
Lesson Notes
Instinct: behavior without being taught (not
learned); a response that is inborn (coded in
the genes) and performed correctly the first
time.
Learned Behavior: change in behavior
based on practice or experience.
Types of Learned Behavior:
1. Imprinting: newborn recognizes and
follows the first moving object they see
(e.g., duckling follows human)
Lesson Notes
2. Conditioning: a specific stimulus or
response leads to a good or a bad outcome
(e.g., Pavlov’s dog, salivate at the sound of
a bell).
3. Trial-and-Error Learning: repeated
practice that results in a reward and avoids
behaviors that result in a punishment.
4. Insight Learning: using what you know
to solve a problem.
Lesson Notes
Patterns of Behavior
Communication: animals use sounds,
scents, body movements to communicate.
Pheromone: a chemical released by one
animal that affects the behavior of another
animal of the same species (e.g., ant
pheromone trail).
Aggression: a threatening behavior that
one animal uses to gain control over another
animal. Aggression is due to competition
over limited resources (food, water, space,
shelter, and mates).
Lesson Notes
Courtship Behavior: behavior to prepare for
mating.
Group Behavior: beneficial for safety in
numbers and sharing (cooperation) in work,
food, water, shelter.
Circadian Rhythms: behavior cycles that
occur over a day (e.g., awake/work daylight,
sleep night time).
Hibernation: sleep/reduced activity during
winter in which the need for food has stopped.
Migration: routine, seasonal journey of an
animal from one place to another and back
again.
