This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

EL1 learners' receptive morphological words (root, inflected, and derived words) develop on different scales, but whether they develop similarly in EFL learners' language production is still unknown and deserves an examination. The answer may provide a clue to theoretical controversy about whether language learners' morphologically defined words…

This article introduces the NFL7 (Nuclear Family List 7), a list of the 2,887 most frequent "nuclear" word families, that is, families that include just the most frequent family members and exclude those that constitute less than 7% of family occurrences. The NFL7 was developed by using a dedicated computer program, the Nuclear List…

This study explores the effects of receptive derivational affix knowledge, derivative frequency, part of speech, and vocabulary breadth on production of derivatives. Twenty-one speakers of English as a first language and 107 learners of English as a second language were asked to produce derivatives for 90 prompt words on a decontextualized…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…

The present study sets out to measure Turkish EFL learners' receptive affix knowledge and productive derivative vocabulary knowledge. More specifically, the extent to which Turkish EFL learners recognize written form of affixes, know the meaning of affixes and determine the part of speech of the derivatives produced by means of affixes and how…

Maternal input influences language development in children with Down syndrome (DS) and typical development (TD). Telegraphic input, or simplified input violating English grammatical rules, is controversial in speech-language pathology, yet no research to date has investigated whether mothers of children with DS use telegraphic input. This study…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

Morphological awareness is essential for the successful use of a language and morphological instruction may facilitate the acquisition of new words. This quasi-experimental research examines the effects of affix instruction on acquiring morphologically complex words. Two measures of receptive and productive affix knowledge were administered to 92…

Based on the growing support that relates reading comprehension with morphological awareness, a short intervention was designed and piloted to see if instruction in morphological analysis could improve reading comprehension or vocabulary with primary school students. The intervention was piloted with a small group focusing on pre- and post-test…

This study investigated the learnability of multiple word knowledge aspects and the relationship between the word knowledge aspects. A total of 261 Thai high school students were measured on receptive and productive word knowledge aspects: word parts, the form-meaning link, and collocations. The current findings indicated that word parts are…

Immersion students' language abilities are generally characterized by strong receptive skills (listening, reading) and less developed productive skills (speaking, writing) when compared with L1 speakers of the immersion language (e.g., Allen et al. 1990; Cummins 1998; Harley 1992). In this paper we report results from a six-month mixed-methods…

This study explored whether form-focused instruction (FFI) and peer corrective feedback (CF) facilitated vocabulary development during peer interaction (PI). Third-semester learners of German were assigned to a PI group (peer interaction only), PI FFI group (peer interaction and form-focused instruction), or PI FFI CF group (peer interaction,…

This study contributes to what is known about the nature of unbalanced bilingualism that emerges in language contact situations by examining the morphological knowledge of Spanish receptive heritage bilinguals (RHBs). RHBs were exposed to Spanish in their homes and communities but received formal schooling in English. These bilinguals have been…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…
