1.
**Behaviorism**: This theory places a strong emphasis on how
reinforcement and conditioning work to help people acquire
languages. One possible slogan for it might be "learning through
stimulus-response associations." Ideas exchanged together with
suggestions: - **Krashen's Monitor Hypothesis**: While behaviorism
emphasizes external stimuli, exposure and practice are crucial for
language acquisition, according to Krashen's Monitor Hypothesis.
2. **Innatism**: According to this belief, people are born with the
ability to learn languages. One possible slogan for it might be
"language is innate and hardwired." Ideas exchanged together with
suggestions: While both theories suggest that language acquisition is
a natural process, the **Teachability/Learnability Hypothesis** also
recognizes the need of training in maximizing language acquisition.
3. **Interactionism**: This theory holds that interacting with people
and the surroundings helps people acquire a language. "Language
learning is a social and interactive process" may be its catchphrase.
Ideas exchanged together with suggestions: **Krashen's Monitor
Hypothesis**: Interactionism, which emphasizes the value of
meaningful communication for language acquisition, is consistent
with Krashen's theory of the relevance of social interaction in
language learning. - **Teachability/Learnability Hypothesis**:
Another key component of interactionism is its emphasis on the
importance of feedback and training in language acquisition. Each of
these suggestions interacts with different theories of language
learning, demonstrating how diverse viewpoints can enhance and
expand our comprehension of the acquisition of second and foreign
languages.
Krashen’s monitor model theory
It contains five hypotheses.
1-) Language learning and acquisition.
2-) Natural order.
3-) Affective filter.
4-) Monitor.
5-) comprehensible
 1- language learning and acquisition
Learning and acquisitions are different things. Learning is
consciously studying but acquisitions are learning through exposure.
If there is a extreme loading on learning, then it can turn into
acquisition.
2- Monitoring
Thinking one step in advance what you are going to tell. Learners
use this monitoring process.
3- natural order hypothesis
Everything has a time and place in language. For example First ing
takes places according to Krashen. Which stages come in which time
can be predictable. The easiest one doesn’t have to be previous
one.
4- Input/ comprehensible hypothesis
Input should be comprehensible even a little more than
comprehensible but it shouldn’t be so much. There is a limit. If it is
too comprehensive than learning won’t be successful. It should be
understandable.
5- Affection filter
Anxiety, stress, motivation, negative attitude, national/ethnic
identity they are all filters.
