German plural formation appears unsystematic and largely arbitrary to many second language (L2) learners. While some approaches have attempted to identify patterns and rules to help L2 learners (e.g., Anton et al., 2017; Di Donato & Clyde, 2020; Kraiss, 2014), one central observation from linguistic analysis has been absent from pedagogical…

To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…

This paper explores the hypothesis that children pay more attention to phonological cues than semantic cues when acquiring grammatical patterns. In a series of artificial allomorphy learning experiments with adults and children we find support for this hypothesis but only for those learners who do not show clear signs of explicit learning. In…

Beginning with the classic work of Shepard, Hovland, & Jenkins (1961), Type II visual patterns (e.g., exemplars are large white squares OR small black triangles) have held a special place in investigations of human learning. Recent research on Type II "linguistic" patterns has shown that they are relatively frequent across languages…

Learning how to spell is important. Most people would agree that the ability to spell correctly is an essential trait of literate people, and that students must be taught how to spell correctly; however, there is still debate among parents, educators, and the public as to how spelling should be taught in the schools. This paper reexamines and…

The morphological structure of the word has a central function in the organization of the mental lexicon and word recognition. Polymorphemic words in Arabic are composed of two non-concatenated morphemes: root and word-pattern. This study is the first to address the issue of nominal-pattern priming among young developing Arabic speakers. I…

Purpose: Our purpose was to test the competing sources of input (CSI) hypothesis by evaluating an intervention based on its principles. This hypothesis proposes that children's use of main verbs without tense is the result of their treating certain sentence types in the input (e.g., "Was 'she laughing'?") as models for declaratives…

Following a year of study of Saudi Arabian Sign Language (SASL), we are documenting our findings to provide a grammatical sketch of the language. This paper represents one part of that endeavor and focuses on a description of selected morphemes, both manual and non-manual, that have appeared in the course of data collection. While some of the…

Metalinguistic skills may develop differently in multilingual and monolingual children. This study investigated effects of immersion in Cherokee as a second language on young children's (4;5-6;1) skills of noticing morphological forms/patterns in English, their first language, by comparing English past tense skills on two nonword and two real-word…

The authors compared performance on two variants of the primed lexical decision task to investigate morphological processing in native and non-native speakers of English. They examined patterns of facilitation on present tense targets. Primes were regular (billed-BILL) past tense formations and two types of irregular past tense forms that varied…

This study discusses cognitive processes when speakers produce language in real time, with its focus on cross-linguistic differences in the procedural aspect of language use. It demonstrates that the syntactic characteristics of a language shape the speakers' overall process of sentence planning and production: how they construct sentential…

Native English speakers tend to exclude regular plural inflection when producing English noun-noun compounds (e.g., "rat-eater" not "rats-eater") while allowing irregular plural inflection within compounds (e.g., "mice-eater") (Clahsen, 1995; Gordon, 1985; Hayes, Smith & Murphy, 2005; Lardiere, 1995; Murphy, 2000). Exposure to the input alone has…

It is cross-linguistically common for languages to undergo a diachronic increase in the range of adverbial notions that can be expressed by means of infinitival constructions, and the Romance languages are a good example of this process. Examining the development of adverbial "prepositional infinitive" constructions in Spanish, Portuguese and…

In this paper the morphological argument for the conditioning of Sanskrit aspiration and deaspiration is renewed in theoretically current terms, bringing forth new arguments and examining previously undiscussed major weaknesses in the purely phonological (autosegmental) argument. Relevant phonological, morphological, and lexical facts are…
