Production of tense marking in successive bilingual children: when do they converge with their monolingual peers?
Children with English as a second language (L2) with exposure of 18 months or less exhibit similar difficulties to children with Specific Language Impairment in tense marking, a marker of language impairment for English. This paper examines whether L2 children with longer exposure converge with their monolingual peers in the production of tense marking.
38 Turkish-English L2 children with a mean age of 7;8 and 33 monolingual age-matched controls completed the screening test of the Test of Early Grammatical Impairment (TEGI). The L2 children as a group were as accurate as the controls in the production of -ed, but performed significantly lower than the controls in the production of third person –s. Age and YoE affected the children’s performance. The highest age-expected performance on the TEGI was attested in eight and nine year-old children who had 4-6 YoE. L1 and L2 children performed better in regular compared to irregular verbs, but L2 children overregularized more than L1 children and were less sensitive to the phonological properties of verbs. The results show that tense marking and the screening test of the TEGI may be promising for differential diagnosis in eight and nine year-old L2 children with at least four YoE
Processing of regular and irregular past tense morphology in highly proficient second language learners of English: a self-paced reading study
Dual-system models suggest that English past tense morphology involves two processing routes: rule application for regular verbs and memory retrieval for irregular verbs (Pinker, 1999). In second language (L2) processing research, Ullman (2001a) suggested that both verb types are retrieved from memory, but more recently Clahsen and Felser (2006) and Ullman (2004) argued that past tense rule application can be automatised with experience by L2 learners. To address this controversy, we tested highly proficient Greek-English learners with naturalistic or classroom L2 exposure compared to native English speakers in a self-paced reading task involving past tense forms embedded in plausible sentences. Our results suggest that, irrespective to the type of exposure, proficient L2 learners of extended L2 exposure apply rule-based processing

Rule-Based Morphological Processing in a Second Language: A Behavioural Investigation
According to dual-system accounts of English past-tense processing, regular forms are decomposed into their
stem and affix (played=play+ed) based on an implicit linguistic rule, whereas irregular forms (kept) are
retrieved directly from the mental lexicon. In second language (L2) processing research, it has been suggested
that L2 learners do not have rule-based decomposing abilities, so they process regular past-tense forms similarly to irregular ones (Silva & Clahsen 2008), without applying the morphological rule. The present study investigates morphological processing of regular and irregular verbs in Greek-English L2 learners and native English speakers. In a masked-priming experiment with regular and irregular prime-target verb pairs (playedplay/kept-keep), native speakers showed priming effects for regular pairs, compared to unrelated pairs,
indicating decomposition; conversely, L2 learners showed inhibitory effects. At the same time, both groups
revealed priming effects for irregular pairs. We discuss these findings in the light of available theories on L2

Differential effects of internal and external factors on the development of vocabulary, tense morphology and morpho-syntax in successive bilingual children
The present study investigates the effects of child internal (age/time) and child external/environmental factors on the development of a wide range of language domains in successive bilingual (L2) Turkish-English children of homogeneously low SES. Forty-three L2 children were tested on standardized assessments examining the acquisition of vocabulary and morpho-syntax. The L2 children exhibited a differential acquisition of the various domains: they were better on the general comprehension of grammar and tense morphology and less accurate on the acquisition of vocabulary and (complex) morpho-syntax. Profile effects were confirmed by the differential effects of internal and external factors on the language domains. The development of vocabulary and complex syntax were affected by internal and external factors, whereas external factors had no contribution to the development of tense morphology. These results are discussed in light of previous studies on the impact of internal and external factors in child L2 acquisition
Production and processing asymmetries in the acquisition of tense morphology by sequential bilingual children
This study investigates the production and on-line processing of English tense morphemes by sequential bilingual (L2) Turkish-speaking children with more than three years of exposure to English. Thirty nine 6-9-year-old L2 children and 28 typically developing age-matched monolingual (L1) children were administered the production component for third person –s and past tense of the Test for Early Grammatical Impairment (Rice & Wexler, 1996) and participated in an on-line word-monitoring task involving grammatical and ungrammatical sentences with presence/omission of tense (third person –s, past tense -ed) and non-tense (progressive –ing, possessive ‘s) morphemes. The L2 children’s performance on the on-line task was compared to that of children with Specific Language Impairment (SLI) in Montgomery & Leonard (1998, 2006) to ascertain similarities and differences between the two populations. Results showed that the L2 children were sensitive to the ungrammaticality induced by the omission of tense morphemes, despite variable production. This reinforces the claim about intact underlying syntactic representations in child L2 acquisition despite non target-like production (Haznedar & Schwartz, 1997)
Determiner spreading as DP-predication
Determiner Spreading (DS) occurs in adjectivally modified nominal phrases comprising more than one definite article, a phenomenon that has received considerable attention and has been extensively described in Greek. This paper discusses the syntactic properties of DS in detail and argues that DS structures are both arguments and predication configurations involving two DPs. This account successfully captures the word-order facts and the distinctive interpretation of DS, while also laying the groundwork towards unifying it with other structures linking two DPs in a predicative relation

Production of relative clauses in monolingual Turkish children
Research on the production of relative clauses (RCs) has shown that in English, although children
start using intransitive RCs at an earlier age, more complex, bi-propositional object RCs appear later
(Hamburger & Crain, 1982; Diessel and Tomasello, 2005), and children use resumptive pronouns
both in acceptable and unacceptable ways (McKee, McDaniel, & Snedeker, 1998; McKee &
McDaniel, 2001).
To date, it is unclear whether or not the same picture emerges in Turkish, a language with an SOV
word-order and overt case marking. Some studies suggested that subject RCs are more frequent in
adults and children (Slobin, 1986) and yield a better performance than object RCs (Özcan, 1996), but
others reported the opposite pattern (Ekmekçi, 1990). Our study addresses this issue in Turkish
children and adults, and uses participants’ errors to account for the emerging asymmetry between
subject and object RCs.
37 5-to-8 year old monolingual Turkish children and 23 adult controls participated in a novel
elicitation task involving cards, each consisting of four different pictures (see Figure 1). There were
two sets of cards, one for the participant and one for the researcher. The former had animals with
accessories (e.g., a hat) whereas the latter had no accessories. Participants were instructed to hold
their card without showing it to the researcher and describe the animals with particular accessories.
This prompted the use of subject and object RCs. The researcher had to identify the animals in her
card (see Figure 2).
A preliminary repeated measures ANOVA with the factor Group (pre-school, primary-school
children) showed no differences between the groups in the use of RCs (p>.1), who were therefore
collapsed into one for further analyses. A repeated measures ANOVA with the factors Group
(children, adults) and RC-Type (Subject, Object) showed that children used fewer RCs than adults
(F(1,58)=7.54, p<.01), and both groups used fewer object than subject RCs (F(1,58)=22.46, p<.001),
but there was no Group by RC-Type interaction (see Figure 3). A similar ANOVA on the rate of
grammatical RCs showed a main effect of Group (F(1,58)=77.25, p<.001), a main effect of RC-Type
(F(1,58)=66.33, p<.001), and an interaction of Group by RC-Type (F(1,58)=64.6, p<.001) (see
Figure 4). Children made more errors than adults in object RCs (F(1,58)=87.01, p<.001), and
children made more errors in object compared to subject RCs (F(1,36)=106.35, p<.001), but adults
did not show this asymmetry. The error analysis revealed that children systematically avoided the
object-relativizing morpheme –DIK, which requires possessive agreement with the genitive-marked
subject. They also used resumptive pronouns and resumptive full-DPs in the extraction site similarly
to English children (see Figure 5).
These findings are in line with Slobin (1986) and Özcan (1996). Children’s errors suggest that they
avoid morphosyntactic complexity of object RCs and try to preserve the canonical word order by
inserting resumptive pronouns in the extraction site. Finally, cross-linguistic similarity in the
acquisition of RCs in typologically different languages suggests a higher accessibility of subject RCs
both at the structural (Keenan and Comrie, 1977) and conceptual level (Bock and Warren, 1986)
