Frequency and proficiency have been found to play an important role in second language (L2) phrasal processing. However, existing research has largely focused on English and other European languages, with other commonly used languages, such as Chinese, being largely disregarded. To fill this gap, we carried out two experiments to investigate how…

This study examined how linguistic complexity features contribute to second language (L2) processing effort by analyzing the Dutch English-L2 learners' eye movements from GECO and MECO, two eye-tracking corpora. Processing effort was operationalized as reading rate, mean fixation duration, regression rate, skipping rate, and mean saccade…

Naturalistic language learning is contextually grounded. When people learn their first (L1) and often their second (L2) language, they do so in various contexts. In this dissertation I examine the effect of various contexts on language development. Part 1 describes the effects of textual, linguistic context in reading. I employed an eye-tracking…

This study used eye-tracking to investigate the real-time processing of phonetic and semantic radicals (components of Chinese characters that give clues to their pronunciation and meaning) by intermediate-level university Chinese foreign language (CFL) learners. Additionally, the study examined how knowledge and awareness of radicals affect…

Relative clauses have long been examined in research on first (L1) and second (L2) language acquisition and processing, and a large body of research has shown that object relative clauses (e.g. 'The boy that the girl saw') are more difficult to process than subject relative clauses (e.g. 'The boy that saw the girl'). Although there are different…

The present study investigated the second language processing of grammatical mood in Spanish. Eye-movement data from a group of advanced proficiency second language users revealed nativelike processing with irregular verb stimuli but not with regular verb stimuli. A comparison group of native speakers showed the expected effect with both types of…

We investigated the role of cue weighting, second language (L2) proficiency, and L2 daily exposure in L2 learning of suprasegmentals different from the first language (L1), using eye-tracking. Spanish monolinguals, English-Spanish learners, and Mandarin--Spanish learners saw a paroxytone and an oxytone verb (e.g., "FIRma-firMÓ"…

The mechanisms underlying native (L1) and non-native (L2) sentence processing have been widely debated. One account of potential L1/L2 differences is that L2 sentence processing underuses syntactic information and relies heavily on semantic and surface cues. Recently, an alternative account has been proposed, which argues that the source of L1/L2…

Past work has suggested that L1 readers retrieve idioms (i.e., "spill the tea") directly vs. matched literal controls ("drink the tea") following unbiased contexts, whereas L2 readers process idioms more compositionally. However, it is unclear whether this occurs when a figuratively or literally biased context…

During spoken word processing, native (L1) listeners use allophonic variation to predictively rule out word competitors and speed up word recognition. There is some evidence that second language (L2) learners develop an awareness of allophonic distributions in their L2, but whether they use their knowledge to facilitate word recognition online,…

Adult second language learners arrive at the language learning situation with an already formed first language grammar system in place. The study of cross-language similarity across the first and second languages explores how the similarities and differences in the two languages make learning more or less difficult, particularly for adult…

Numbers (i.e. 45) are symbols that are common in reading texts in various forms such as dates, percentages, and quantity expressions. Each digit corresponds to a word, unlike words in which each letter represents a phoneme. Despite their high frequency in reading texts, eye movement research on numeral processing is still rare. Numerals are easy…

Readers should construct a coherent discourse during reading comprehension. The ability to build coherence has been examined using coherence and cohesion judgment tasks. Although eye-tracking studies have been conducted on building coherence or processing cohesion among native language users, few such studies have been conducted with second…

Little is known about how nonnative speakers process novel language patterns in the input they encounter. The present study examines whether nonnatives develop a sensitivity to novel binomials and their ordering preference from context. Thirty-nine nonnative speakers of English (L1 Arabic) read three short stories seeded with existing binomials…

Although text readability has traditionally been measured based on simple linguistic features, recent studies have employed natural language processing techniques to develop new readability formulas that better represent theoretical accounts of reading processes. This study evaluated the construct validity of different readability formulas,…
