Outline[ edit ] The five hypotheses that Krashen proposed are as follows: 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.
Possessive 's The girl's book. Order of acquisition In the s, several studies investigated the order in which learners acquired different grammatical structures.
Furthermore, it showed that the order was the same for adults and children, and that it did not even change if the learner had language lessons. This supported the idea that there were factors other than language transfer involved in learning second languages, and was a strong confirmation of the concept of interlanguage.
However, the studies did not find that the orders were exactly the same. Although there were remarkable similarities in the order in which all learners learned second-language grammar, there were still some differences among individuals and among learners with different first languages.
It is also difficult to tell when exactly a grammatical structure has been learned, as learners may use structures correctly in some situations but not in others.
Thus it is more accurate to speak of sequences of acquisition, in which specific grammatical features in a language are acquired before or after certain others but the overall order of acquisition is less rigid.
For example, if neither feature B nor feature D can be acquired until feature A has been acquired and if feature C cannot be acquired until feature B has been acquired but if the acquisition of feature D does not require the possession of feature B or, therefore, of feature Cthen both acquisition order A, B, C, D and acquisition order A, D, B, C are possible.
Variability[ edit ] Although second-language acquisition proceeds in discrete sequences, it does not progress from one step of a sequence to the next in an orderly fashion.
There can be considerable variability in features of learners' interlanguage while progressing from one stage to the next.
However, most variation is systemic variation, variation that depends on the context of utterances the learner makes. Language transfer One important difference between first-language acquisition and second-language acquisition is that the process of second-language acquisition is influenced by languages that the learner already knows.
This influence is known as language transfer. If this happens, the acquisition of more complicated language forms may be delayed in favor of simpler language forms that resemble those of the language the learner is familiar with. Stephen Krashen took a very strong position on the importance of input, asserting that comprehensible input is all that is necessary for second-language acquisition.
Further evidence for input comes from studies on reading: One tenet of Krashen's theory is that input should not be grammatically sequenced. He claims that such sequencing, as found in language classrooms where lessons involve practicing a "structure of the day", is not necessary, and may even be harmful.
For example, students enrolled in French- language immersion programs in Canada still produced non-native-like grammar when they spoke, even though they had years of meaning-focused lessons and their listening skills were statistically native-level.
According to Long's interaction hypothesis the conditions for acquisition are especially good when interacting in the second language; specifically, conditions are good when a breakdown in communication occurs and learners must negotiate for meaning.
The modifications to speech arising from interactions like this help make input more comprehensible, provide feedback to the learner, and push learners to modify their speech.

The increasing prevalence of pain-related illnesses, and their economic and psychological consequences, has resulted in a heightened interest in both the neurobiological mechanisms underpinning pain, and the effects of pain on a range of processes, including cognition.
