Marzena Watorek is Professor in Linguistics at the University Paris 8. Her research interests include first and second language acquisition, particularly discourse production, initial processing of the input by adult learners, and the interface between language acquisition and teaching.Sandra Benazzo is Associate Professor in Linguistics and French as a Second Language at the University Lille 3. Her research mainly concerns L2 acquisition in the domain of temporality, information structure, discourse organization and the comparison with L1 acquisition.Maya Hickmann is Research Director in the Laboratoire Structures Formelles du Langage (CNRS and Université Paris 8). Her research mainly focuses on the role of structural vs. functional and universal vs. language-specific determinants in first and second language acquisition.

This well-edited collection of papers responds to the theoretical issues that concerned Clive Perdue throughout his productive career. The 29 chapters examine similarities and differences between monolinguals, childhood bilinguals, and adult and child learners of a second language. We see how learner productions are influenced by perceptual abilities, L1 transfer, and explicit learning as they operate across the lifespan, rather than some uniform expiration of a critical period.
