Linguist and educator Stephen Krashen proposed the Monitor Model, his theory of second language acquisition, in Principles and practice in second language acquisition as published in 1982. According to the Monitor Model, five hypotheses account for the acquisition of a second language: • • • • • Affective filter hypothesis However, in spite of the popularity and influence of the Monitor Model, the five hypotheses are not without criticism.

The following sections offer a description of the fifth and final hypothesis of the theory, the affective filter hypothesis, as well as the major criticism by other linguistics and educators surrounding the hypothesis. Definition of the Affective Filter Hypothesis The fifth hypothesis, the affective filter hypothesis, accounts for the influence of affective factors on second language acquisition. Affect refers to non-linguistic variables such as motivation, self-confidence, and anxiety.

According to the affective filter hypothesis, affect effects acquisition, but not learning, by facilitating or preventing comprehensible input from reaching the language acquisition device. In other words, affective variables such as fear, nervousness, boredom, and resistance to change can effect the acquisition of a second language by preventing information about the second language from reaching the language areas of the mind. Furthermore, when the affective filter blocks comprehensible input, acquisition fails or occurs to a lesser extent then when the affective filter supports the intake of comprehensible input. The affective filter, therefore, accounts for individual variation in second language acquisition.

Second language instruction can and should work to minimize the effects of the affective filter. Criticism of the Affective Filter Hypothesis The final critique of Krashen’s Monitor Model questions the claim of the affective filter hypothesis that affective factors alone account for individual variation in second language acquisition. First, Krashen claims that children lack the affective filter that causes most adult second language learners to never completely master their second language. Such a claim fails to withstand scrutiny because children also experience differences in non-linguistic variables such as motivation, self-confidence, and anxiety that supposedly account for child-adult differences in second language learning. Furthermore, evidence in the form of adult second language learners who acquire a second language to a native-like competence except for a single grammatical feature problematizes the claim that an affective filter prevents comprehensible input from reaching the language acquisition device.

As Manmay Zafar asks, “How does the filter determine which parts of language are to be screened in/out?” In other words, the affective filter hypothesis fails to answer the most important question about affect alone accounting for individual variation in second language acquisition. Although the Monitor Model has been influential in the field of second language acquisition, the fifth and final hypothesis, the affective filter hypothesis, has not been without criticism as evidenced by the critiques offered by other linguists and educators in the field.

(May 2008) () The input hypothesis, also known as the monitor model, is a group of five hypotheses of developed by the linguist in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977.

The hypotheses put primary importance on the comprehensible input (CI) that language learners are exposed to. Understanding spoken and written language input is seen as the only mechanism that results in the increase of underlying, and language output is not seen as having any effect on learners' ability. Furthermore, Krashen claimed that linguistic competence is only advanced when language is subconsciously acquired, and that conscious learning cannot be used as a source of spontaneous language production. Finally, learning is seen to be heavily dependent on the mood of the learner, with learning being impaired if the learner is under stress or does not want to learn the language. Krashen's hypotheses have been influential in, particularly in the, but have received criticism from some academics.

Two of the main criticisms state that the hypotheses are untestable, and that they assume a degree of separation between acquisition and learning that has not been proven to exist. Contents • • • • • • • • • • • • • • Outline [ ] The five hypotheses that Krashen proposed are as follows: • The input hypothesis.

This states that learners progress in their knowledge of the language when they comprehend language input that is slightly more advanced than their current level. Krashen called this level of input 'i+1', where 'i' is the learner's interlanguage and '+1' is the next stage of language acquisition. • The acquisition–learning hypothesis claims that there is a strict separation between acquisition and learning; Krashen saw acquisition as a purely subconscious process and learning as a conscious process, and claimed that improvement in language ability was only dependent upon acquisition and never on learning. • The monitor hypothesis states that consciously learned language can only be used to monitor language output; it can never be the source of spontaneous speech. • The natural order hypothesis states that language is acquired in a particular order, and that this order does not change between learners, and is not affected by explicit instruction.

• The affective filter hypothesis. This states that learners' ability to acquire language is constrained if they are experiencing negative emotions such as fear or embarrassment.

At such times the affective filter is said to be 'up'. If i represents previously acquired linguistic competence and extra-linguistic knowledge, the hypothesis claims that we move from i to i+1 by understanding input that contains i+1. Extra-linguistic knowledge includes our knowledge of the world and of the situation, that is, the.

The +1 represents new knowledge or language structures that we should be ready to acquire. The comprehensible input hypothesis can be restated in terms of the. For example, if we acquire the in a linear order (1, 2, 3.), then i represents the last rule or language form learned, and i+1 is the next structure that should be learned. It must be stressed, however, that just any input is not sufficient; the input received must be comprehensible.

According to Krashen, there are three corollaries to his theory. Corollaries of the input hypothesis [ ] • Talking (output) is not practicing. Krashen stresses yet again that speaking in the does not result in language acquisition. Although speaking can indirectly assist in language acquisition, the ability to speak is not the cause of language learning or acquisition. Instead, is the effect of language acquisition.

• When enough comprehensible input is provided, i+1 is present. If language models and teachers provide enough comprehensible input, then the structures that acquirers are ready to learn will be present in that input. According to Krashen, this is a better method of developing grammatical accuracy than direct grammar teaching.

• The teaching order is not based on the natural order. Instead, students will acquire the language in a natural order by receiving comprehensible input. Acquisition-learning hypothesis [ ] In modern, there are many theories as to how humans are able to develop ability. According to 's acquisition-learning hypothesis, there are two independent ways in which we develop our linguistic skills: acquisition and learning. This theory is at the core of modern language acquisition theory, and is perhaps the most fundamental of Krashen's theories. Acquisition of language is a natural,, and process of which individuals need not be aware.

One is unaware of the process as it is happening and, when the new knowledge is acquired, the acquirer generally does not realize that he or she possesses any new knowledge.

This process is similar to the process that children undergo when learning their native language. Acquisition requires meaningful interaction in the target language, during which the acquirer is focused on meaning rather than form. Learning a language, on the other hand, is a conscious process, much like what one experiences in. New knowledge or language forms are represented consciously in the learner's mind, frequently in the form of language 'rules' and ', and the process often involves error correction. Involves formal instruction and, according to Krashen, is less effective than acquisition. Learning in this sense is conception or conceptualisation: instead of learning a language itself, students learn an abstract, conceptual of a language, a 'theory' about a language (a grammar).

Monitor hypothesis [ ] The monitor hypothesis asserts that a learner's learned system acts as a monitor to what they are producing. In other words, while only the acquired system is able to produce spontaneous speech, the learned system is used to check what is being spoken.

Before the learner produces an utterance, he or she internally scans it for errors, and uses the learned system to make corrections. Self-correction occurs when the learner uses the Monitor to correct a sentence after it is uttered. According to the hypothesis, such self-monitoring and self-correction are the only functions of conscious language learning.

The Monitor model then predicts faster initial progress by adults than children, as adults use this ‘monitor’ when producing L2 (target language) utterances before having acquired the ability for natural performance, and adult learners will input more into conversations earlier than children. [ ] Three conditions for use of the monitor [ ] According to Krashen, for the Monitor to be successfully used, three conditions must be met: • The acquirer/learner must know the rule This is a very difficult condition to meet because it means that the speaker must have had explicit instruction on the language form that he or she is trying to produce. • The acquirer must be focused on correctness He or she must be thinking about form, and it is difficult to focus on meaning and form at the same time. • The acquirer/learner must have time to use the monitor Using the monitor requires the speaker to slow down and focus on form.

Difficulties using the monitor [ ] There are many difficulties with the use of the monitor, making the monitor rather weak as a language tool. • Knowing the rule: this is a difficult condition to meet, because even the best students do not learn every rule that is taught, cannot remember every rule they have learned, and can't always correctly apply the rules they do remember.

Furthermore, not every rule of a language is always included in a text or taught by the teacher. • Having time to use the monitor: there is a price that is paid for the use of the monitor- the speaker is then focused on form rather than meaning, resulting in the production and exchange of less information, thus slowing the flow of conversation. Some speakers over-monitor to the point that the conversation is painfully slow and sometimes difficult to listen to. • The rules of language make up only a small portion of our language competence: Acquisition does not provide 100% language competence. There is often a small portion of grammar, punctuation, and spelling that even the most proficient native speakers may not acquire.

While it is important to learn these aspects of language, since writing is the only form that requires 100% competence, these aspects of language make up only a small portion of our language competence. Due to these difficulties, Krashen recommends using the monitor at times when it does not interfere with communication, such as while writing. Natural order hypothesis [ ].
