Its about how language develop and acquired by children.

5. History of language
development
• Traditionally, language development depends
upon the principle of reinforcement.
• Principles of reinforcement is psychological
concept based on the idea that the
consequences of an action will influence
future behavior.

6. • Operant conditioning is a type of learning where
behavior is controlled by consequences.

7. Operant conditioning
Positive
Reinforcement
strengthens a
behavior by
providing a
consequence
an individual
finds rewarding.
Negative
Reinforcement
strengthens
behavior
because it
stops or
removes an
unpleasant
experience.
Punishment
the opposite of
reinforcement
since it is
designed to
weaken or
eliminate a
response rather
than increase it.

8. Example
 Positive reinforcement
 Giving a child a compliment or candy for a job well done.
 Watching your favorite TV show after doing all your homework.
 Negative reinforcement
 ~Daydreaming or doodling in boring class (reinforces
daydreaming behavior by removing boredom).
 ~Watching TV when you worry about a test (procrastination or giving
up on it) (reinforces TV watching behavior by removing worry)
 Punishment
 Teen is grounded for misbehavior.
 Yelling “No!” at a dog jumping up on a person (adds
scold to reduce behavior)


9. • Reinforcers: is a response from the
environment that increase the probability of a
behavior being repeated.
• Punishers: is a response from environment
that decrease the likelihood of a behavior
being repeated. Weakens behavior.
• In the process of language acquisition: the
caregiver is the stimulus given to the child
who babbles and coos as a response. Thus
reinforcement occurs and the child is patted
or caressed when he speak, then he forms
language producing habits.

10. • Other learning theorist viewed that
language primarily learned through
imitation.

11. Nativist theory
• Human are born with
certain capacities to
perceive the world in
particular way. These
capacities are often
immature or
incomplete at birth
but develop gradually.

15. Interaction theory

18. Language Acquisition
Support System
• It refers to the family and the social
environment of the children which interact
and acquire language.

19.  Parents communicate in
ritualistic scenarios.
 Easy comprehensible
and predictable
language.
 Emotionally charge
situation.
 Repetition of acts and
language.

23. Psuedodialogues
• this is one of the early training
devices characterized by the
give and take conversation
between the child and the
mother or other person. Adult
maintains the flow of
conversation.

24. Protodeclaratives
• an infant uses gestures to make some
sort of statement about an object. (the
child want to share with you what he
experience. He want you to know what he
experience and he want you to experience
it too)

26. Protoimparatives
• gestures of an infant or young child may
use to get someone to do something he or
she wants. Children can make statement
about things and get other people to do
things for them. (commanding or
requesting)
