The Monitor Hypothesis A linguistic expression originates in the system of acquired knowledge, but prior to output a “Monitor” checks it against consciously known rules and may modify the expression before it is uttered.

What makes input into intake? Apperception: Recognizing the gap between what L2’er knows and what there is to know.

Foreigner talk Like the better-known phenomenon of “baby talk”, it also turns out that people conversing with others whom they perceive to be non-native speakers (NNSs) will often use a form of “foreigner talk”—modified language forms presumably intended to simplify the utterance.

Healthy miscommunication A failure to communicate can serve to focus attention on areas where the NNS’s grammar is non-native-like, prompting negotiation for meaning and providing possible intake data.

Michael Long’s “Interaction Hypothesis” is that this kind of negotiation for meaning and resulting attention is necessary for advancement toward the grammar of the target grammar—in part because it connects input, existing knowledge, selective attention, and output in productively trying to solve a current language deficiency.

Recall that one of the crucial features of parameters is that (ideally) each parameter setting has a cluster of effects. It’s not just that the verb appears before adverbs—it is that the verb moves into the tense position, which means it appears before adverbs and before negation.

Fitting someone with prisms that change the angle of incoming visual stimuli causes initial visual confusion, but they “get used to it” and soon don’t even notice anything unusual.

and language attrition It is a very common phenomenon that, having learned an L2 and having become quite proficient, one will still “forget” how to use it after a period of non-use. It is a very common phenomenon that, having learned an L2 and having become quite proficient, one will still “forget” how to use it after a period of non-use. While very common, it’s not very surprising—it’s like calculus. If L2 is a skill like calculus, we’d expect this. While very common, it’s not very surprising—it’s like calculus.

L1 attrition Much more surprising is the fact that sometimes under the influence of a dominant L2, skill in the L1 seems to go. Much more surprising is the fact that sometimes under the influence of a dominant L2, skill in the L1 seems to go. Consider the UG/parameter model; a kid’s LAD faced with PLD, automatically sets the parameters in his/her head to match those exhibited by the linguistic input. L1 is effortless, fast, uniformly successful… biologically driven, not learning in the normal sense of learning a skill.

UG in L2A We’ve looked at the questions concerning whether when learning a second language, one can adapt the “parameter settings” in the new knowledge to the target settings (where they differ from the L1 settings), but this is even more dramatic—it would seem to actually be altering the L1 settings.

Italian English Italian is a “null subject” language that allows the subject to be dropped in most cases where in English we’d use a pronoun Italian is a “null subject” language that allows the subject to be dropped in most cases where in English we’d use a pronoun (Possible to use a pronoun in Italian, but it conveys something pragmatic: contrastive focus or change in topic) (Possible to use a pronoun in Italian, but it conveys something pragmatic: contrastive focus or change in topic) English is a “non-null-subject” language that does not allow the subject to be dropped out, pronouns are required (even sometimes “meaningless” like it or there).

Italian, null subjects Q: Perchè Maria è uscite? ‘Why did M leave?’ Q: Perchè Maria è uscite? ‘Why did M leave?’ A1: Lei ha deciso di fare una passeggiata. A1: Lei ha deciso di fare una passeggiata. A2: Ha deciso di fare une passenggiata. ‘She decided to take a walk.’ A2: Ha deciso di fare une passenggiata. ‘She decided to take a walk.’ Monolingual Italian speaker would say A2, but English-immersed native Italian speaker will optionally produce (and accept) A1.

L1 attrition It seems that the acceptability of overt pronouns (in the L1 “attriters”) broadens compared to their L1, the acceptability of null pronouns becomes more restricted. It seems that the acceptability of overt pronouns (in the L1 “attriters”) broadens compared to their L1, the acceptability of null pronouns becomes more restricted. Pronouns in a null subject language are marked—they are restricted to particular discourse contexts ([+topic shift], according to Sorace). Pronouns in a null subject language are marked—they are restricted to particular discourse contexts ([+topic shift], according to Sorace). What seems to happen is that the pronouns revert to the unmarked case ([±topic shift] like in English).

Sorace notes that the observed cases of attrition of this sort seem to be the ones involved with discourse and pragmatics, not with fundamental grammatical settings. (The attrited Italian is still a null-subject language, for example—null subjects are still possible and used only in places where null subjects should be allowed).

Parameter settings in L1 appear to be safe, but the discourse-pragmatic constraints seem to be somehow susceptible to high exposure to conflicting constraints in other languages.
