Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

Lexical knowledge is complex, multidimensional, and difficult to pin down to a set of defined components. The development, organization, and use of lexical knowledge in the first and additional languages are studied in a number of neighbouring disciplines beyond second language acquisition and applied linguistics, including psycholinguistics,…

The study investigates the relationship between lexical encoding and production in order to establish whether learners are able to produce a difficult contrast in words that they merged in their mental lexicon. Forty American English learners of Russian were tested on their production and lexical encoding of familiar and highly-frequent words with…

Four experiments were conducted to examine the role of orthotactic probability, i.e. the sequential letter probability, in the early stages of vocabulary acquisition by adult native speakers and advanced learners of German. The results show different effects for orthographic probability in incidental and intentional vocabulary acquisition: Whereas…

Recent studies in the acquisition of a second language (L2) phonology have revealed that orthography can influence the way in which L2 learners come to establish target-like lexical representations (Escudero et al., 2008, 2014; Escudero and Wanrooij, 2010; Showalter, 2012; Showalter and Hayes-Harb, 2013). Most of these studies, however, involve…

When both members of a phonemic contrast in L2 (second language) are perceptually mapped to a single phoneme in one's L1 (first language), L2 words containing a member of that contrast can spuriously activate L2 words in spoken-word recognition. For example, upon hearing cattle, Dutch speakers of English are reported to experience activation…

In three experiments, we examine the effects of semantic context and word concreteness on the mapping of existing meanings to new words. We developed a new-word-learning paradigm in which participants were required to discover the meaning of a new-word form from a specific verbal context. The stimulus materials were manipulated according to word…

Recent research indicates that knowledge of words' spellings can influence knowledge of the phonological forms of second language (L2) words when the first and second languages use the same orthographic symbols. It is yet unknown whether learners can make similar use of unfamiliar orthographic symbols. In this study we investigate whether native…

One of the questions frequently asked in second language (L2) lexical research is how L2 learners' patterns of lexical organization compare to those of native speakers (NSs). A growing body of research addresses this question by using word association (WA) tests. However, little research has been done on the role of language proficiency in the…

Reviews four recent books of current research in vocabulary acquisition: "Exploring the Second Language Mental Lexicon," (D. Singleton); "Assessing Vocabulary," (J. Read); "Vocabulary in Language Teaching" (N. Schmitt); "Learning Vocabulary in Another Language" (L.S.P. Nation). (Author/VWL)

In this study of the placement of sentence negation in third language acquisition (L3), we argue that there is a qualitative difference between the acquisition of a true second language (L2) and the subsequent acquisition of an L3. Although there is considerable evidence for L2 influence on vocabulary acquisition in L3, not all researchers believe…

Describes two experiments that examined the acquisition of second language lexical fluency. Considers the implications of these results for models of the developing lexicon. (Author/VWL)

Second-language (L2) researchers suggest that C-tests, developed as norm-referenced measures for proficiency and placement testing, can be used in L2 vocabulary research. This article illustrates how researchers can use measurement theory for L2 research by weighing validity justifications. A theoretical definition of vocabulary ability is…
