In Krashen's theory of second-language acquisition he claims that there is distinction between language acquisition and language learning, a distinction which other second-language acquisition researchers have called "perhaps the most important conceptualization" in the field and which has made possible the most productive models of SLA.…

Humans can attribute beliefs to others. However, it is unknown to what extent this ability results from an innate biological endowment or from experience accrued through child development, particularly exposure to language describing others' mental states. We test the viability of the language exposure hypothesis by assessing whether models…

Exemplar-based learning requires: (1) a segmentation procedure for identifying the units of past experiences that a present experience can be compared to, and (2) a similarity function for comparing these past experiences to the present experience. This article argues that for a learner to learn a language these two mechanisms will require…

Several studies have explored the use of iconic gestures to improve the learning of foreign vocabulary. In this quest, words for abstract concepts have been largely neglected, under the assumption that abstract concepts have poor or non-existent sensory-motor representations. Yet, the Conceptual Metaphor Theory suggests that they are grounded on…

Learning part names, such as hands of a clock, can be a challenge for children because of the whole object assumption; that is, a child will assume that a given label refers to the whole object (e.g., a clock) rather than the object part (e.g., hands of a clock). We examined the effect of gaze shifting and deliberate pointing on learning part…

Children's remarkable ability to generalize beyond the input and the resulting overregularizations/ irregularizations provide a platform for a discussion of whether morphology learning uses analogy-based, rule-based, or statistical learning procedures. The present study, testing 115 children (aged 3 to 10) on an elicited production task,…

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…

It is often assumed that cross-linguistically more prevalent distinctions are easier to learn potentially due to their conceptual naturalness. Prior work supports this hypothesis in phonology, morphology and syntax but has not addressed semantics. This work aims to unravel the potential factors that contribute to the learnability and the…

Over the past two decades, the Involvement Load Hypothesis (ILH) has become a popular buzzword in the field of Second Language Acquisition (SLA). Although applications of the ILH can improve students' learning of productive vocabulary, this effect appears to be transitory. Students' learning of productive vocabulary often fades over time, as shown…

Language is one of the hallmarks of intelligence, demanding explanation in a theory of human cognition. However, language presents unique practical challenges for quantitative empirical research, making many linguistic theories difficult to test at naturalistic scales. Artificial neural network language models (LMs) provide a new tool for studying…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

Previous research comparing communicative to non-communicative computer-mediated tasks requiring output production found an advantage in L2 vocabulary learning efficiency in favor of the communicative task (Hughes, 2023). The present study analyzes the chat data from Hughes (2023) to determine what features of interaction may have contributed to…

Emotion plays important roles in learning, memory, and other cognitive processes; it does so not only in the form of "macro-level emotion" (e.g., salient affective states and self-reportable motivational currents) but also in the form of "micro-level emotion" (e.g., subtle feelings and linguistic attributes that are usually…

This research paper presents a quasi-experimental empirical study investigating the effects of structured input and structured output tasks on the acquisition of English causative forms. This research is framed on VanPatten's (1996) input processing theory. The grammatical form chosen for this investigation is affected by a processing strategy…

In terms of language teaching, individuals' ability to master their native language and grammar rules directly affects foreign language acquisition processes. Considering this situation, which is also defined as "interdisciplinary" the background of foreign language learning processes in the context of the native language should be…
