In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory…

This study is a replication and extension of Morgan-Short et al.'s (2018) investigation into the role of attention in input processing by L1-Polish learners of L2-Spanish, with proficiency and language of assessment explored as two key methodological factors. Our aims were twofold: to investigate learners' comprehension in different conditions…

The current study investigated how the processing of triple cognates (words sharing form and meaning across three languages) is modulated by the semantic bias of sentence context in a reading task. In the study, Polish-German-English trilinguals read English sentences while their eye movements were monitored. The sentences were either semantically…

Mass adoption of neural machine translation (NMT) tools in the translation workflow has exerted a significant impact on the language services industry over the last decade. There are claims that with the advent of NMT, automated translation has reached human parity for translating news (see, e.g. Popel et al. 2020). Moreover, some machine…

The present paper investigates the acquisition of L3 Polish by L1 Italian university students of L2 Russian. The participants had never studied the L3 prior to the experiment, but took a meta-linguistically explicit course in Slavic Linguistics focussing on Polish/Russian contrastive grammar. The main research question is whether or not the…

Evidence from the contemporary translation services market and many centuries of translation practice demonstrate that translation into a non-native language (L2 translation) can be performed effectively, despite the once-strong resistance to it on the grounds of it being perceived as unprofessional and inherently deficient. L2 translation is in…

The present study draws on the theoretical framework of translanguaging and seeks to shed light on the patterns of translanguaging and how translanguaging affects meaning-making processes among bilingual children in preschool. This case study focuses on 8 months of observation and recordings of pupils ranging in age from 3 to 6 years. The gathered…

Word knowledge and the speed of word processing in monolingual children and adults are influenced by word properties, such as the age of acquisition (AoA), imageability, and frequency. Understanding how different properties of words contribute to the ease of processing by bilingual children is a critical step for establishing models of childhood…

This study addresses the question of how the main factors related to input--including the environment in which children are exposed to both languages, the relative timing of the onset of the exposure to them and the amount of input--affect bilingual language acquisition at primary-school age. We examined the data of 42 German Polish bilinguals who…

Although previous research has observed a facilitative influence of the first language (L1) on the acquisition and processing of gender agreement in a second language (L2), particularly in language pairs with similar gender agreement marking, the question of whether knowledge of two languages with gender can confer an additional advantage for…
