Recent studies of heritage speakers, many of whom possess incomplete knowledge of their family language, suggest that these speakers may be linguistically superior to second language (L2) learners only in phonology but not in morphosyntax. This study reexamines this claim by focusing on knowledge of clitic pronouns and word order in 24 L2 learners…

Any person who has taught Spanish as a second language or who has interacted with a non-native speaker of Spanish can easily tell that mastering the correct use of the copulas "ser" and "estar" is very difficult in both spoken and written production. But L2 learners are not alone. The Spanish copulas also present difficulty and frustration for L2…

The obligatory use of the preposition a with animate, specific direct objects in Spanish ("Juan conoce a Maria" "Juan knows Maria") is a well-known instance of Differential Object Marking (DOM; Torrego, 1998; Leonetti, 2004). Recent studies have documented the loss and/or incomplete acquisition of several grammatical features in Spanish heritage…

This study investigates knowledge of gender agreement in Spanish L2 learners and heritage speakers, who differ in age and context/mode of acquisition. On some current theoretical accounts, persistent difficulty with grammatical gender in adult L2 acquisition is due to age. These accounts predict that heritage speakers should be more accurate on…

Investigates the relationship between lexical semantics and derivational morphology in the acquisition of causative/inchoative-related verbs in Turkish as a second language (L2) by Spanish and English speakers. Suggests that L2 learners are attuned to the rich morphology of Turkish and that the acquisition of derivational morphology and lexical…

Investigates whether intermediate Turkish-speaking and English-speaking learners of Spanish know which unaccusative verbs alternate in transitivity and which ones do not, and whether they find causative errors natural with intransitive verbs. Results confirm similar findings to those reported in English interlanguage and first-language acquisition…

In this experimental study, we focus on the following semantic universal: if a habitual clause reading, then generic pronominal subject; if an episodic clause reading, then specific pronominal subject. We argue that although this set of two conditionals is a universal property of all natural languages, English-speaking second-language (L2)…

Two experiments examine the effects of the native language on the second language acquisition argument structure. The linguistic focus is on agentive verbs of directed motion and change-of-state verbs in Spanish and English. Examined whether Spanish and Turkish learners of English undergeneralize the transitivity alternation with manner of motion…

It has been suggested that tense and aspect distributions are very difficult to learn in a second language (L2), they are prone to fossilize universally, and their interpretive properties are subject to a critical period (Coppieters, 1987). This study focuses on the acquisition of the semantic implications of the preterite-imperfect contrast in…

This experimental study on English, Spanish, and Turkish as second languages investigates the interaction of universal principles and first language knowledge in interlanguage grammars by focusing on verbs that participate in the causative/inchoative alternation. (Author/VWL)

Investigates whether Spanish- and Turkish-speaking learners of English discover the semantic and syntactic constraints on the causative/inchoative alternation in the absence of overt morphological clues. Results of a picture judgment task show that second language learners do discover these properties and that overall verbs appear to cluster in…

Presents three related experiments on the acquisition of two classes of causative verbs: physical change of state verbs with agentive subjects and psychological change of state verbs with experiencer objects in English, Spanish, and Turkish as second languages by speakers whose native languages are English, Spanish, Turkish, and Japanese.…

This study compares the linguistic knowledge of adult second language (L2) learners, who learned the L2 after puberty, with the potentially "eroded" first language (L1) grammars of adult early bilinguals who were exposed to the target language since birth and learned the other language simultaneously, or early in childhood (before age 5). I make…

Many simultaneous bilinguals exhibit loss or incomplete acquisition of their heritage language under conditions of exposure and use of the majority language (Silva-Corvalan, 1994, 2003; Polinsky, 1997; Toribio, 2001; Montrul, 2002). Recent work within discourse-functional (Silva-Corvalan 1994) and generative perspectives (Sorace, 2000; Montrul;…
