“…In addition, the few prior studies on the retrieval production effect employed quite diverse experimental conditions to examine the effect of the response format. For example, these studies used different memory measures (cued recall, Putnam & Roediger, 2013; free recall, Smith et al, 2013), different delays (15 minutes, Smith et al, 2013, Experiment 1; 2 days, Putnam & Roediger, 2013; 1 week, Jönsson et al, 2014), different testing-effect paradigms (e.g., with test-ensuing restudy, Jönsson et al, 2014; Putnam & Roediger, 2013; without test-ensuing restudy, Smith et al, 2013), and different materials (categorised words, Smith et al, 2013; word pairs, Jönsson et al, 2014; Putnam & Roediger, 2013; action phrases, Kubik et al, 2019; key-term definitions, Tauber et al, 2018). In sum, the different forms of productive encoding ensuing retrieval (enactment vs. classical verbal pronunciation) and these methodological differences might moderate whether an added benefit beyond retrieval is produced.…”
