Early vocabulary development benefits from diverse lexical exposures within children's language environment. However, the influence of lexical diversity on children as they enter middle childhood and are exposed to multimodal language inputs remains unclear. This study evaluates global and local aspects of lexical diversity in three…

Inhibitory control ability may affect the orthographic neighborhood size (ONS) effect by inhibiting the semantic activation of neighbors. However, few studies have explored whether and how inhibitory control plays a role in the ONS effect on recognition of Chinese words. This study screened individuals with high and low inhibitory control…

While much work has emphasized the role of the environment in language learning, research equally reports consistent effects of the child's knowledge, in particular, the words known to individual children, in steering further lexical development. Much of this work is based on cross-sectional data, assuming that the words typically known to…

Growing up with multiple siblings might negatively affect language development. This study examined the associations between birth order, sibling characteristics and parent-reported vocabulary size in 6163 Norwegian 8- to 36-month-old children (51.4% female). Results confirmed that birth order was negatively associated with vocabulary, yet…

The optimal amount of first language (L1) and second language (L2) to use in L2 learning has been constantly debated (e.g., Cummins, 2007; Hall & Cook, 2012). This study situated the debate of L1 and L2 use in the context of vocabulary learning from reading by examining the gloss language effect (i.e., L1 vs. L2 glosses). Important factors…

The last decade has seen an exponential rise in children's digital media use, as well as growing evidence that it is associated with changes in children's vocabulary. However, while high rates of low-quality digital media have been associated with lower "amounts" of words a child says, little work has examined whether digital media…

While there are well-known demonstrations that children can use distributional information to acquire multiple components of language, the underpinnings of these achievements are unclear. In the current paper, we investigate the potential pre-requisites for a distributional learning model that can explain how children learn their first words. We…

This study attempted to investigate the effects of two forms of text-based glosses, namely dynamic and non-dynamic glosses, on vocabulary learning of EFL learners. To this end, two experimental groups and one control group, each comprising 25 participants, took part in the study. The DIALANG test was employed as a homogenizing tool to ensure the…

There is a growing body of research examining the efficacy of teaching a foreign language using procedures that would lead to generative learning. This study assessed the acquisition of foreign tacts and the emergence of bidirectional intraverbal responses (native-foreign and foreign-native) as a function of target stimulus preference. Three…

Both classic thought experiments and recent empirical evidence suggest that children frequently encounter new words whose meanings are underdetermined by the extralinguistic contexts in which they occur. The role that these referentially ambiguous events play in children's word learning is central to ongoing debates in the field. Do children learn…

There is considerable lab-based evidence for successful incidental learning, in which a learner's attention is directed away from the to-be-learned stimulus and towards another stimulus. In this study, we extend incidental learning research into the language learning classroom. Three groups of adult second language (L2) learners (N = 52) engaged…

Infants experience language in rich multisensory environments. For example, they may first be exposed to the word applesauce while touching, tasting, smelling, and seeing applesauce. In three experiments using different methods we asked whether the number of distinct senses linked with the semantic features of objects would impact word recognition…

Despite the growing interest in incorporating textual glosses into second language (L2) reading in hypermedia and paper media, no agreements have been reached as to whether and what extent a textual gloss facilitates L2 learners' vocabulary acquisition in hypermedia and paper media. The present study meta-analysed the overall effects of textual…

The collocation frequency of words in the language environment contributes to early vocabulary development. Vocabulary size, in turn, predicts children's reading comprehension skills later in development. Both collocation frequency and reading comprehension have been connected to inferential reasoning at different time points in development. Here,…

This dissertation is a program evaluation of the Building Blocks of Comprehension vocabulary program, which was first implemented during the 2019-2020 school year by the English department at the school site. The study aimed to investigate the impact of morphological instruction on student vocabulary acquisition and reading comprehension.…
