Lexical processing is influenced by a word’s semantic diversity, as estimated corpus-derived metrics. Although this suggests that contextual variation shapes verbal learning and memory, it not clear what diversity represents why influences lexical processing. Word experiments simulations offer an opportunity to manipulate directly measure the effects on In Experiment 1, adults read novel words ...

This study analyzes lexical proficiency in oral and written texts produced by second language (L2) learners of English. The purpose of the study is to examine relationships between analytic scores of depth of lexical knowledge, breadth of lexical knowledge, and access to core lexical items and holistic scores of lexical proficiency. A corpus of 240 spoken texts and 240 written texts produced by...

What is the root cause of word frequency effects on lexical decision times? Murray and Forster (2004) argued that such effects are linear in rank frequency, consistent with a serial search model of lexical access. This paper (i) describes a method of testing models of such effects that takes into account the possibility of parametric overfitting; (ii) illustrates the effect of corpus choice on ...

Word frequency is an important predictor of word-naming and lexical decision times. It is, however, confounded with contextual diversity, the number of contexts in which a word has been seen. In a study using a normative, corpus-based measure of contextual diversity, word-frequency effects were eliminated when effects of contextual diversity were taken into account (but not vice versa) across t...

This paper presents an investigation of lexical first language (L1) attrition, assessing in what way a decrease in lexical accessibility manifests itself for long-term residents in a second language (L2) environment. We question the measures typically used in attrition studies (formal tasks and type-token ratios) and argue for an in-depth analysis of free spoken data, including factors such as ...

The lexical diversity of children with specific language impairment (SLI) (ages 3 years 7 months to 7 years 3 months) was compared to that of normally developing same-age peers and younger normally developing children matched according to mean length of utterance in words (MLUw). Lexical diversity was calculated from spontaneous speech samples using D, a measure that uses repeated calculations ...

This study investigates how cohesion manifests in readers’ thought processes while reading texts when they are instructed to engage in self-explanation, a strategy associated with deeper, more successful comprehension. In Study 1, college students (n = 21) were instructed to either paraphrase or self-explain science texts. Paraphrasing was characterized by greater cohesion in terms of lexical o...

GLAWI is a free, large-scale and versatile Machine-Readable Dictionary (MRD) that has been extracted from the French language edition of Wiktionary, called Wiktionnaire. In (Sajous and Hathout, 2015), we introduced GLAWI, gave the rationale behind the creation of this lexicographic resource and described the extraction process, focusing on the conversion and standardization of the heterogeneous...
