It has been known since at least the 1960s that small changes in pupil diameter in response to a mental task are indicative of processing effort associated with this task. More recently, with the advent of modern eye-trackers, which also measure the pupil diameter, pupillometry has been "rediscovered" by language researchers and the…

Discusses dependence and frequency data in second language acquisition research and investigates the violation of the "independent observation" assumption as well as the effect of including interaction terms in frequency data analysis. Argues in favor of using multifactorial frequency data analyses over multiple chi-squares to take into account…

Responds to an article on top-down versus bottom-up analyses of interlanguage data in second language acquisition research that argues in favor of using multifactorial frequency data analyses over multiple chi-squares to take into account dependence and interaction of the frequency data.

Much research has posited a developmental sequence approach in second-language acquisition. This study reexamines the original social-psychological research upon which the multidimensional model is based and shows that it is incorrect because of faulty analysis. It also examines the limited applicability/generalizability of the developmental…

Results of a study of two methods of morpheme quantification--one by suppliance in obligatory contexts, the other by target-like use--produced substantially different percentages of accuracy for subjects' production of the morphemes progressive "-ing," progressive auxiliary, and past irregular. This demonstrates that, as a consequence of applying…

Illustrates the advantages of laboratory research into second language acquisition (SLA) by describing two studies of acquisition of second language syntax. The first, conducted in Wales, addresses the question of whether human morphological abilities can be understood in terms of associative processes, and the second presents a bootstrapping…

The acquisition of German in three adult Poles over a three-year period is examined based on an acquisition profile of each person that specified the sequences in acquisition. The findings suggest that cognitive factors must be considered to explain the varying degree of success in the acquisition process. (40 references) (Author/LB)
