Interference: unique source of forgetting in working memory?

In their opinion article, Lewandowsky, Oberauer and Brown [1] make a strong case against time-based accounts of forgetting in short-term andworkingmemory.We argue, however, that the interference-based account they favor is underspecified, that the time-loss functions predicted by time-based models are misconstrued and that the contradictory findings issued from the time-based resource-sharing (TBRS) model [2] are not properly addressed.
