Current quantitative methods in second language (L2) acquisition have proven useful in examining how phraseological unit production changes over time. However, these methods are limited in that they do not allow for the analysis of individual differences in those changes. This study demonstrates the potential for Latent Curve Modeling, a type of…

Investigates numerous individual difference measures to determine their underlying dimensions, to contrast their predictive validities and to evaluate their contributions in a causal model of second language acquisition. Findings indicate that substantial links exist among affective measures and achievement. (56 references) (Author/CK)
