The detailed comments of our colleagues on our keynote article suggest that they all value the integration of various sorts of empirical data into one formalized model of bilingual word recognition. Taking this position, our peers propose further specifications or adaptations of the proposed BIA+ model with respect to its representations, processes or control structure; and they indicate what, in their view, should be the next step in model development or empirical testing. We are grateful for their contributions, which we will carefully think through in the coming time and use as a basis for future implementations.
