Language is a product of both biological and cultural evolution. Clues to the origins of key structural properties of language can be found in the process of cultural transmission between learners. Recent experiments have shown that iterated learning by human participants in the laboratory transforms an initially unstructured artificial language…

It is argued that if theoretical goals are formulated to account for language learnability, a different markedness construct than the linguistic and psycholinguistic constructs usually applied is necessary--the projection model. The theoretical considerations for such a model are delineated, and the model is tested. (MSE)

A longitudinal study of a Japanese-speaking learner of English as a second language (ESL) analyzed the learner's article system and found that it was not target-like but also not totally random. (Author/CB)

Examines error gravity research design and its theoretical assumptions. Results indicate that investigators have only skimmed the surface of the process of error evaluation, which is shaped by extralinguistic factors. The article concludes that researchers should reconceptualize error gravity research and reassess earlier studies to confirm or…
