 Much of the impetus for the emergence of the field was due to a trend, beginning in the late 1990s, towards increased interdisciplinarity among philosophers working on memory (Hoerl &amp; McCormack 2001; Sutton 1998), a trend which reinvigorated and transformed older philosophical debates by bringing them into contact with empirical and theoretical developments in psychology and the sciences of memory more broadly. To cite just two examples among the many discussed below, empirical research on the constructive character of remembering has intensified philosophical debates over the viability of the influential causal theory of memory (Robins 2016b) and the associated concept of memory traces (De Brigard 2014b), while theoretical frameworks which situate remembering as a form of imaginative mental time travel have lent new urgency to longstanding debates over the relationship between memory and imagination (Debus 2014; Perrin &amp; Michaelian 2017).
