Introduction.
Animalbehaviorincludes all the ways
animals interact with other organisms and
the physical environment.
Behaviorcan also be defined as a change
in the activity of an organism in response
to a stimulus, an external or internal cue or
both.
Two Types:-
➢Innate
➢Learned.
Characteristics of Innate Behavior
➢Genetically based, it is inherited from parents
➢Fixed, experiences do not alter the behavior.
➢It is independent of the environment
➢Adapts the animal to its environment making survival more likely.
➢Innate behavior can only change by the mutation of genes.
➢The knee-jerk reflex tested by doctors and the sucking reflex of human infants,
are very simpleinnate behaviors.
Classification of
Innate behavior
kinesis
Taxis
Reflex
Instinct
Kinesis
•For some lower animals, reflex like movement is non directional and
random.
•Such undirected orientation is called kinesis.
•Orthokinesis: in which the speed of movement of the individual is
dependent upon the stimulus intensity. Ex-locomotion of woodlice in
relation to humidity.
•Klinokinesis: in which the frequency or rate of turning is proportional to
stimulus intensity. Ex-some flatworms turns more frequently in
response to light. Cockroach more active during darkness.
Kinesis
Taxis
➢Taxis is a behavioral response of acellor anorganism to an
externalstimulus.
➢The movement may be positiveor negative.
➢A positive taxis is one in which theorganism or a cell moves towards
the source ofstimulation(attraction).
➢A negative taxis is when theorganism or acellmoves away from the
source of stimulation (repulsion).
Reflex Action
➢Reflex action is a sudden and involuntary response to stimuli.
➢It helps organisms to quickly adapt to an adverse circumstance that
could have the potential to cause bodily harm or even death.
➢The anatomical pathway of a reflex is called thereflex arc.
➢It consists of an afferent (sensory) nerve, usually one or more
interneuronswithin the central nervous system, and an efferent
(motor, secretory, or secreto-motor) nerve.
Reflex
Action
Instinct
➢Instinctis a term used to describe a set of behaviors that are unlearned and
set in motion as the result of some environmental stimuli.
➢The simplest example of an instinctive behavior is afixed action
pattern(FAP).
➢It is different from reflex action as more complex behavior is observed in
instinct. Example-Mother bird feeding her babies, spawning by Salmon,
hibernation in certain animals.
➢Imprinting,a type of instinct is a complex response may involve visual,
auditory, and olfactory signals in the environment surrounding an organism.
IMPRINTING & FAP
Learned Behavior
Learned Behavior
➢Learned behavioris behavior that occurs
only withexperience or practice.
➢It is more flexible than innate behavior.
Methods of learning:
1.Habituation
2.Observational learning
3.Conditioning
4.Insight learning
5.Play
Habituation
➢Habituation is the diminishing of an innate
response to a frequently repeated stimulus.
➢Learn not to respond to a stimulus that is
presented repeatedly without change,
punishment, or reward.
➢Duringhabituation, fewer neurotransmitters
are released at the synapse.
➢Example:-New ringtone will draw attention
initially but later it fails to draw attention!! or,
domesticated birds seldom run away from
people !!
Habituation
Observational Learning
➢Observational learningis learning that occurs
through observing the behavior of others.
➢Albert Bandura formulated the theory of
Observational learning.
➢Bobo doll experiment.
➢The four stages of observational learning are:
✓Attention
✓Retention
✓Production
✓Motivation
Observational
Learning.
(Bobo doll
Experiment)
Conditioning
➢Conditioning,a behavioral process
whereby a response becomes more
frequent or more predictable in a given
environment as a result of reinforcement.
➢Reinforcement typically being a stimulus
or reward for a desired response.
➢Conditioning can be:
✓Classical Conditioning.
✓Operant Conditioning.
➢Both are part of Associative Learning.
Classical Conditioning
➢Classical
conditioningrefers to a
learning procedure in
which a biologically potent
stimulus (e.g. food) is
paired with a previously
neutral stimulus (e.g. a
bell).
➢The famous Ivan Pavlov’s
Experiment with dog.
Operant Conditioning
Method oflearningthat employs
rewards and punishments for behavior.
Also called Instrumental Learning.
B.F. Skinner formulated the theory for
Operant Conditioning.Heidentified
three types of responses, or operant:-
✓Neutral
✓Reinforcers
✓Punishers
Insight learning
➢Insight learningis a type oflearningor
problem solving that happens all-of-a-
sudden.
➢Able to understand the relationships of
various parts of a problem rather than
through trial and error.
➢In other words able to associate various
objects and actions.
➢Wolfgang Kohler formulated this theory on
Chimpanzees.
Play
➢Play is defined as arange of voluntary
and internally motivated
activities(spontaneous actions),
normally associated with enjoyment.
➢Notdirectly related to the immediate
increase of survivalof the organism.
➢Animal to learn the limitation and its
abilities.
➢Helps in parental bonding and
develop social skills.
➢Helps to learn about the
environment.
