L2 irregular verb morphology: Exploring behavioral data from intermediate English learners of German as a foreign language using generalized mixed effects models

This paper examines possible psycholinguistic mechanisms governing stem vowel changes of irregular verbs in intermediate English learners of German as a foreign language (GFL). In Experiment 1, nonce-infinitives embedded in an authentic fictional text had to be inflected for German preterite, thus testing possible analogy driven pattern associations. Experiment 2 explored the psycholinguistic reality of the so-called apophonic path by prompting two inflections for one given nonce-word. Data were analyzed using generalized mixed effects models accounting for within-subject as well as within-item variance. The results of Experiment 1 and 2 support the notion of a pattern associator and yield only scarce evidence for the psycholinguistic reality of a universal apophonic path. Therefore, the organization of irregular verb morphology in the mental lexicon of intermediate GFL learners might best be captured by the linguistic notion of structured lexical entries as well as the psycholinguistic mechanism of an analogy-based pattern associator

Children's computation of complex linguistic forms: a study of frequency and imageability effects.

This study investigates the storage vs. composition of inflected forms in typically-developing children. Children aged 8-12 were tested on the production of regular and irregular past-tense forms. Storage (vs. composition) was examined by probing for past-tense frequency effects and imageability effects--both of which are diagnostic tests for storage--while controlling for a number of confounding factors. We also examined sex as a factor. Irregular inflected forms, which must depend on stored representations, always showed evidence of storage (frequency and/or imageability effects), not only across all children, but also separately in both sexes. In contrast, for regular forms, which could be either stored or composed, only girls showed evidence of storage. This pattern is similar to that found in previously-acquired adult data from the same task, with the notable exception that development affects which factors influence the storage of regulars in females: imageability plays a larger role in girls, and frequency in women. Overall, the results suggest that irregular inflected forms are always stored (in children and adults, and in both sexes), whereas regulars can be either composed or stored, with their storage a function of various item- and subject-level factors

On analogy as the motivation for grammaticalization

The number of phenomena which are gathered together under the term 'grammaticalization' is quite large and in some ways quite diverse. For the different types of grammaticalization similar motivating factors have been suggested, similar principles, clines and hierarchies. Some of Lehmann's (1982[1995], 1985) parameters, which have long been considered to characterize processes of grammaticalization, are now under attack from various quarters, and indeed the phenomenon of grammaticalization itself has been questioned as an independent mechanism in language change. This paper addresses a number of problems connected with the 'apparatus' used in grammaticalization and with the various types of grammaticalization currently distinguished. It will be argued that we get a better grip on what happens in processes of grammaticalization and lexicalization if the process is viewed in terms of an analogical, usage-based grammar, in which a distinction is made between processes taking place on a token-level and those taking place on a type-level. The model involves taking more notice of the form of linguistic signs and of the synchronic grammar system at each stage of the grammaticalization process

Production of Inflected Novel Words in Older Adults With and Without Dementia

While cognitive changes in aging and neurodegenerative disease have been widely studied, language changes in these populations are less well understood. Inflecting novel words in a language with complex inflectional paradigms provides a good opportunity to observe how language processes change in normal and abnormal aging. Studies of language acquisition suggest that children inflect novel words based on their phonological similarity to real words they already know. It is unclear whether speakers continue to use the same strategy when encountering novel words throughout the lifespan or whether adult speakers apply symbolic rules. We administered a simple speech elicitation task involving Finnish‐conforming pseudo‐words and real Finnish words to healthy older adults, individuals with mild cognitive impairment, and individuals with Alzheimer's disease (AD) to investigate inflectional choices in these groups and how linguistic variables and disease severity predict inflection patterns. Phonological resemblance of novel words to both a regular and an irregular inflectional type, as well as bigram frequency of the novel words, significantly influenced participants' inflectional choices for novel words among the healthy elderly group and people with AD. The results support theories of inflection by phonological analogy (single‐route models) and contradict theories advocating for formal symbolic rules (dual‐route models).While cognitive changes in aging and neurodegenerative disease have been widely studied, language changes in these populations are less well understood.
