Imagine a three-year longitudinal study of the acquisition of multiple target languagesbylearners of different language backgrounds. It may sound like an idealized examplefrom aresearch-methods lecture, but it is the actual design of the European ScienceFoundation inquiryinto adult second language acquisition and the latest report releasedby Benjamins, a substantialrevision of Volume 5 of the final report on temporality(Bhardwaj, Dietrich, & Noyau,1988). This volume reports on the acquisition of temporality in five target languages (English,German, Dutch, French, and Swedish) by 21learners of six source languages (Punjabi, Italian,Turkish, Arabic, Spanish, and Finnish)with learners from two source languages for each targetlanguage. The volume has eightchapters written by the main authors and cooperatingcontributors: “Introduction” (Dietrich & Perdue), “Frame ofAnalysis” (Klein), five chapters on the acquisition of temporality by targetlanguage—English (Klein), German (Dietrich), Dutch (Klein, Coenen, vanHelvert,& Hendricks), French (Noyau, Houdaïfa, Vasseur, & Véronique), andSwedish(Noyau, Dorriots, Sjöström, & Voionmaa)—and“Conclusions” (Klein, Dietrich, & Noyau).
