In this reply to Salverda (2016), we address a critique of the claims made in our recent study of real-time processing of American Sign Language (ASL) signs using a novel visual world eye-tracking paradigm (Lieberman, Borovsky, Hatrak, & Mayberry, 2015). Salverda asserts that our data do not support our conclusion that native signers and…

Lieberman, Borovsky, Hatrak, and Mayberry (2015) used a modified version of the visual-world paradigm to examine the real-time processing of signs in American Sign Language. They examined the activation of phonological and semantic competitors in native signers and late-learning signers and concluded that their results provide evidence that the…

In this response I discuss several points that Bruton made in his own response paper. I first argue that his main theme, that design factors should be emphasized over statistical analysis, has never been a genuine issue; it is two independent issues, and for each of them I have some concerns about his discussion. I then consider his comments on…

Critiques an article by Virginia LoCastro that contrasted quantitative data (using the Strategy Inventory for Language Learning, or SILL) and qualitative data (using group interviews) and finds the conclusions drawn from the comparison unjustified on various grounds.

Shows that intermediate learners of German whose first language is English experience more semantic difficulties when reading an English text and more syntactic difficulties when reading a German version of the same text. A stronger emphasis on syntactic features, such as word category, agreement relationships, tensing, and word placement in the…
