A premise of statistical learning research is that learners attend to and learn the frequencies of co-occurring sounds in the input, or phonotactic sequences. Inherent to the concepts of both frequency and phonotactics is order, or the temporal arrangement of the relevant elements. Order is similarly inherent to statistical learning, yet the…

This manuscript, as a conceptual article and communication piece, offers insights into the pedagogy of play as a philosophy of education and a wide-ranging set of methods and techniques. It intends to encourage readers to invest (further) in playful learning in language learning. To this aim, playful learning is first problematized within language…

Given its complexity, abstractness, and central role in many logics, negation might be a conceptual accomplishment. Therefore, young children's gradual acquisition of negation words might be due to their undergoing a conceptual change that is necessary to represent logical meanings. However, it's also possible that expressing negation takes time…

Hidden structure refers to the units of organization that a child cannot directly observe when they are learning language (e.g. phonemes, morpheme boundaries, URs, phrases). In this dissertation, I propose a novel computational model that learns hidden structures in-tandem with the grammar. My model consists of two Maximum Entropy sub-models that…

During word learning moments, toddlers experience labels and objects in particular environments. Do toddlers learn words better when the physical environment creates contrasts between objects with different labels? Thirty-six 21- to 24-month-olds (92% White, 22 female, data collected 8/21-4/22) learned novel words for novel objects presented using…

Analogies of the juridical in the technical sphere allow conceptualizations of how our designs do justice to the language abilities being measured, facilitating improvement of the planned arrangements we make. Juridical anticipations within the technical sphere function on the norm side of the latter as requirements to correct aberrations in…

Previous empirical research has shown that Portuguese children aged 4;0 to 6;0 are sensitive to the quality of stem-final vowels when acquiring the irregular plural forms of /l/-final words (acquisition order: plurals of /al, [epsilon]l, [Greek small reversed lunate sigma symbol]l, ul/ > plurals of /il/). This study presents a formal account of…

As an integral part of dynamic assessment, computerized dynamic assessment (CDA) offers learners computer-assisted automated mediation. Accordingly, the possible efficacy of corrective feedback seems to be enhanced with new technologies, such as artificial intelligence tools, that offer automatic corrective feedback. Using technology-enhanced…

The acquisition of variation is a fundamental -- but poorly understood -- part of child language acquisition. We fully endorse Shin and Miller's call for us to recognize the importance of this core issue, and argue that our understanding could be further enriched by greater reliance on convergent methods. As such, we implore researchers to…

Infants are sensitive to statistics in spoken language that aid word-form segmentation and immediate mapping to referents. However, it is not clear whether this sensitivity influences the formation and retention of word-referent mappings across a delay, two real-world challenges that learners must overcome. We tested how the timing of referent…

The boundary effect, namely the infants' failures to compare small and large numerosities, is well documented in studies using visual stimuli. The prevailing explanation is that the numerical system used to process sets up to 3 is incompatible with the system employed for numbers >3. This study investigates the boundary effect in 10-month-old…

Studying early language development has been a challenging task throughout the years. Earlier studies mostly documented language competence only after toddlers had started producing their first words. Theoretical and methodological advances in this domain brought about more sophisticated ways of probing into early development by exploiting overt…

Very large numbers words such as "hundred," "thousand," "million," "billion," and "trillion" pose a learning problem for children because they are sparse in everyday speech and children's experience with extremely large quantities is scarce. In this study, we examine when children acquire the…

There is a current 'theory crisis' in language acquisition research, resulting from fragmentation both at the level of the approaches and the linguistic level studied. We identify a need for integrative approaches that go beyond these limitations, and propose to analyse the strengths and weaknesses of current theoretical approaches of language…

Reduplication, the copying operation employed in natural language morphophonology (e.g., Ilokano pluralization, [kaldin] 'goat'; [kal-kaldin] 'goats'; Hayes and Abad, 1989, p. 357), creates repetition structures within surface word forms. Though reduplication and surface repetitions have been extensively studied, two questions remain unresolved.…
