Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…

The picture-word task presents participants with a number of pictured objects together with a written distractor word superimposed upon each picture, and their task is to name the depicted object while ignoring the distractor word. Depending on the specific picture and word combination, various effects, including the identity facilitation effect…

This study investigated the role of orthographic information in the acquisition of non-native speech sounds by monolingual English listeners. Two potentially important orthographic variables were explored: Orthographic compatibility (whether the orthographic information supports or contradicts the distributional information) and orthographic…

This article provides a review of previous studies that have examined the effects of orthography on establishing contrastive phonological representations in second language acquisition and presents results from an original study on Mandarin speakers' production of English stops investigating how the presence of orthography affects the production…

The present study investigated the influence of orthographic input on the recognition of second language (L2) spoken words with phonological variants, when first language (L1) and L2 have different orthographic structures. Lexical encoding for intermediate-to-advanced level Mandarin learners of Korean was assessed using masked cross-modal and…

This dissertation studies the acquisition of Mandarin relative clauses (RCs), including the distributional pattern of different RC types in adult child-directed speech (study 1) and four-year-old Mandarin-speaking children's comprehension of different RC types (study 2). An RC is a subordinate clause that modifies a noun and is embedded within a…

Within the field of linguistics, whether considering language contact situations (Weinreich, 1979) or foreign language education (Lado, 1957), the topic of language transfer, especially as it relates to pronunciation, has always been an item of particular interest. While research on such transfer has mostly focused on various phenomena of the L1…

Previous studies on spoken word production have shown that native English speakers used phoneme-sized units (e.g., a word-initial phoneme, C) to produce English words, and native Mandarin Chinese speakers employed syllable-sized units (e.g., a word-initial consonant and vowel, CV) as phonological encoding units in Chinese. With spoken word…

This study examined how mode of input affects the learning of pronunciation and form-meaning connection of second language (L2) words. Seventy-five Japanese learners of English were randomly assigned to 1 of 3 conditions (reading while listening, reading only, listening only), studied 40 low-frequency words while viewing their corresponding…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

According to the principle of inverse effectiveness (PIE), weaker responses to information in one modality (i.e., unisensory) benefit more from additional information in a second modality (i.e., multisensory; Meredith & Stein, 1986). We suggest that the PIE may also inform whether perceptual fluency affects judgments of learning (JOLs). If…

Analysis of second language (L2) learners' language development can allow valid and reliable assessment of the learners' L2 linguistic knowledge, which can enable the teachers and researchers to choose appropriate teaching or experimental materials (Bardovi-Harlig & Bofman, 1989; Wolfe-Quintero et al., 1997). However, most language development…

Task-irrelevant background sound can disrupt performance of visually based cognitive tasks. The cross-modal breakdown of attentional selectivity in the context of reading was addressed using analyses of eye movements. Moreover, the study addressed whether task-sensitivity to distraction via background speech on reading was modulated by the…

Understanding discourse connectives is an important step to achieving effective verbal communication. Yet, the ability of adult native speakers to understand the broad range of connectives found in most Indo-European languages has seldom been assessed. In this article we demonstrate that some adults have difficulties recognizing correct and…

In conversational speech, it is very common for words' segments to be reduced or deleted. However, previous research has consistently shown that during spoken word recognition, listeners prefer words' canonical pronunciation over their reduced pronunciations (e.g., pretty pronounced [word omitted] vs. [word omitted]), even when the latter are far…
