Answering calls to map college-level proficiency development (Modern Language Association, 2007) and longitudinally chart language learning (Barkaoui, 2014; Ortega & Byrnes, 2008), we mapped the oral proficiency growth of 1,922 lower-division college students of Chinese, French, Russian, and Spanish (in the second, third, or fourth semester of…

As part of the shift within second language acquisition (SLA) research toward complex systems thinking, researchers have called for investigations of social network structure. One strand of social network analysis yet to receive attention in SLA is network statistical models, whereby networks are explained in terms of smaller substructures of…

This classroom-based study explored links among second language (L2) learners' interaction mindsets, interactional behaviors, and L2 development in the context of peer interaction. While peer interaction research has revealed that certain interactional behaviors (e.g., receiving corrective feedback and engaging in collaborative interaction) assist…

Recent theorizing on second language (L2) motivation has proposed viewing motivation as a function of the language learners' vision of their desired future language selves. This would suggest that the intensity of motivation is partly dependent on the learners' capability to generate mental imagery. In order to test this hypothesis, this study…

Agrees with Oller and Perkins (1978) that correlation and causation are not equivalent and that correlations between invalid measures yield no important conclusions. In addition, Oller and Perkins' arguments against the validity of self-report measurements are examined, as well as evidence for a causal relation between variance in affective…

Discusses three possible sources of nonrandom but extraneous variance in self-reported attitude data, and demonstrates that these data may be surreptitious measures of verbal intelligence and language proficiency. (Author/AM)
