The study examined how learners' motivational dispositions predict the complexity, accuracy, fluency of their oral task performance and their overall second language proficiency. Eighty-one speakers of English as a second language in the United States completed a regulatory focus and a regulatory mode questionnaire, an oral interview task, and a…

This study examines a 30-item Spanish elicited imitation task (EIT) as a measure of global language proficiency for heritage language (HL) learners of Spanish. Results from Rasch modeling suggest that, while EIT scores demonstrated excellent reliability, the ability of much of the HL sample far exceeded the difficulty of the items. Differential…

We examined what causes L1-L2 differences in sensitivity to prominence cues in discourse processing. Participants listened to recorded stories in segment-by-segment fashion at their own pace. Each story established a pair of contrasting items, and one item from the pair was rementioned and manipulated to carry either a contrastive or…

The Elicited Imitation Task (EIT) is a popular technique for efficiently measuring global proficiency in multiple languages, and accumulated evidence indicates high reliability and strong relationships with other proficiency measures. Nevertheless, several dimensions of EIT design remain open to investigation, including the assumption that a pause…

To examine the effects of task repetition with different schedules, English-as-a-foreign-language classroom learners performed the same oral narrative task six times under three different schedules. They narrated the same six-frame cartoon story (a) six times consecutively in one class (massed practice), (b) three times at the beginning and at the…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

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…

Second language (L2) teachers may shy away from self-assessments because of warnings that students are not accurate self-assessors. This information stems from meta-analyses in which self-assessment scores on average did not correlate highly with proficiency test results. However, researchers mostly used Pearson correlations, when polyserial could…

The current study examined the effects of task condition (TC; single vs. dual) and proficiency level (PL) on self-monitoring of second language (L2) speakers. Data were collected from sixty-six female L2 learners of English performing two speaking tasks under two task conditions. While performance in the single-task condition involved only…

In comparative studies focusing on context of learning, the main contexts under investigation have been study abroad (SA), at-home formal instruction (AH), and domestic immersion (IM). With the global status of English and its burgeoning popularity as a medium of instruction in countries where English only holds the status of a lingua franca, a…

This study builds upon previous research investigating the construct validity of phraseological complexity as an index of L2 development and proficiency. Whereas previous studies have focused on cross-sectional comparisons of written productions across proficiency levels, the current study compares the "longitudinal" development of…

Elicited Imitation Tests (EITs) are commonly used in second language acquisition (SLA)/bilingualism research contexts to assess the general oral proficiency of study participants. While previous studies have provided valuable EIT construct-related validity evidence, some key gaps remain. This study uses an integrative data analysis to further…

The current study examined the extent to which cognitive fluency (CF) contributes to utterance fluency (UF) at the level of constructs. A total of 128 Japanese-speaking learners of English completed four speaking tasks--argumentative task, picture narrative task, reading-to-speaking task, and reading-while-listening-to-speaking task--and a battery…

Elicited imitation (EI), a short-cut measure of global proficiency in second language (L2) research, requires participants to listen to sentences and repeat them as closely as possible. To support instrument sharing and assessment of L2 proficiency for longitudinal and crosslinguistic research, we created a parallel form of an EI task (EIT) for L2…

This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence--size, organization, and accessibility--and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three…
