Access to definitions facilitates the learning of word meanings when novel words are encountered in reading. However, the memorial costs and benefits of inferring word meanings from context, compared to seeing definitions of unfamiliar words before reading, are not yet well understood. We conducted two experiments with adult L1 (English) and L2…

A growing field of research has made use of a semiartificial language paradigm to investigate the role of awareness in L2 acquisition. A central and empirically still unresolved issue in this field concerns the possibility of learning implicitly, that is, without intention to learn and without awareness of what has been learned. Up until now,…

This exploratory study aimed to examine whether early exposure to Chinese as a heritage language (CHL) provides facilitation in word-knowledge development in collegiate CHL learners by comparing word-level subskills, including oral vocabulary knowledge, print vocabulary knowledge, morphological awareness, and lexical inferencing ability, between…

Research on the age of learning effect on second language learners' foreign accents utilizes human judgments to determine speech production outcomes. Inferences drawn from analyses of these ratings are then used to inform theories. The present study focuses on rater differences in the age of learning effect research. Three groups of raters who…

This study examines the nature of the involvement load (Laufer & Hulstijn, 2001) in second language (L2) lexical input processing through reading by considering the effects of the reader-based factors of L2 reading proficiency and background knowledge. The lexical input processing aspects investigated were lexical inferencing (search), attentional…

This study investigated whether a word-learning method in which learners infer the meaning of unknown words from the context, subsequently verify the meaning with the aid of a word list, and finally memorize the meaning ("meaning-inferred method") leads to better retention than one in which the meaning of unknown words is given in the form of a…

The study of SLA, as is true for much social science research, aims broadly at answering questions of causality--for instance, "Is one learning context more likely than another to promote gains in second language learning?" Context-of-learning research in the study of SLA, however, often involves observational, rather than experimental,…

This follow-up study of a classroom experiment with university English-as-a-Second-Language students that demonstrated incidental acquisition of new lexical knowledge through the reading of thematically-related texts explores how vocabulary knowledge may be acquired as a by-product of reading for comprehension. Findings are interpreted in terms of…

Examines four groups of readers: second-language (L2) intermediate; L2 advanced; first-language (L1) Japanese; and L1 English) when they processed and recalled two passages varying in degree of causal coherence. Findings indicate that L1 readers used much of their attention for higher level processes, whereas L2 readers paid more attention to…
