Written in French, this work reports the results of a longitudinal study of past-time referencein the interlanguages of four Swedish learners of French.

Kihlstedtdiscusses evidence supporting a modified interpretation of Andersen's (1991)developmental stages in past temporal expression and proposes an ordering of aspectual valueassignment to the passé composé andimparfait constructions in Swedish-French interlanguage.
