The role of indirect positive evidence in syntactic acquisition: A look at anaphoric one

چکیده
Language learners are often faced with a scenario where the data allow multiple generalizations, even though only one is actually correct. One promising solution to this problem is that children are equipped with helpful learning strategies that guide the types of generalizations made from the data. Two successful approaches in recent work for identifying these strategies have involved (i) expanding the set of informative data to include INDIRECT POSITIVE EVIDENCE, and (ii) using observable behavior as a target state for learning. We apply both these ideas to the case study of English anaphoric one, using computationally modeled learners who assume one’s antecedent is the same syntactic category as one and form their generalizations based on realistic data. We demonstrate that a learner who is biased to include indirect positive evidence coming from other pronouns in English can generate 18-month-old looking preference behavior. Interestingly, we find that the knowledge state responsible for this target behavior is a context-dependent representation for anaphoric one, rather than the adult representation, but this immature representation can suffice in many communicative contexts involving anaphoric one. More generally, these results suggest that children may be leveraging broader sets of data to make the syntactic generalizations leading to their observed behavior, rather than selectively restricting their input. We additionally discuss the components of the learning strategies capable of producing the observed behavior, including their possible origin and whether they may be useful for making other linguistic generalizations.

Induction problems, indirect positive evidence, and Universal Grammar: Anaphoric one revisited
One motivation for Universal Grammar (UG) comes from the existence of induction problems in language acquisition, and their solutions. Previous induction problem characterizations have typically not recognized that INDIRECT POSITIVE evidence may be both available and useful, in addition to other types of evidence. As a case study, we investigate whether a probabilistic learner utilizing indirec...

This study set out to investigate the distribution of the syntactic properties associatedwith the prodrop parameter by Persian-speaking L2 learners of English in an attemptto examine the (un)attainability of native-like knowledge and (in)accessibility of UGin adult SLA. To do so, 92 participants were assigned into different levels of L2knowledge based on their performances on the Oxford Placeme...
متن کاملAcquisition of English Prenominal and Postnominal Genitives
This study examined the acquisition of prenominal and postnominal genitives by Iranian EFL learners. Two variables were considered: possessive categories and language proficiency. We considered the influence of possessive categories such as lexical modifier, semantic relationship, and weight and syntactic complexity on genitive alternations by Iranian EFL learners. Also, we examined whether the...
متن کاملTask-Specific Artifacts of Parametric Properties in English as a Second Language Acquired by Persian-Speaking Learners
This experimental study investigated the learners’ integrative acquisition of obligatory overt subjects and subject-verb clause agreement in English as an L2. In L1 acquisition research, correlations between superficially unrelated linguistic phenomena are analyzed in terms of integrative effects. For instance, in English L1 acquisition, there is evidence for an integrative appearance of subjec...
