Research indicates that readers break down complex words into their smallest, meaning-based units (morphemes) when spelling (e.g., Senechal, 2000). However, it remains unclear how morphemes are formed and whether newly formed morphological knowledge (i.e., knowledge of morphemes) is strong enough to support word learning. The current research…

Lexical inference through reading is considered an important method for vocabulary building; however, empirical research has not consistently offered strong evidence of the application of lexical inference in second language vocabulary learning. A recently burgeoning line of research focuses on second language (L2) lexical inference of compounds…

While recent studies find that contextual diversity (CD) is a better determinant of visual word recognition than token frequency, there is a dearth of work comparing contextual diversity and token frequency in developing readers. In two sets of character and lexical decision experiments we examined token frequency and contextual diversity effects…

Lexical categories like noun and verb are foundational to language acquisition, but these categories do not come neatly packaged for the infant language learner. Some have proposed that infants can begin to solve this problem by tracking the frequent nonadjacent word (or morpheme) contexts of these categories. However, nonadjacent relationships…

There have been great strides made in research on vocabulary in the last 30 years. However, there has been relatively little progress in the development of new vocabulary tests. This may be due in some degree to the impressive contributions made by tests such as the Vocabulary Levels Test (Nation, 1983; Schmitt et al., 2001) and the Word…
