To examine motor suppression-induced forgetting, we adapted Anderson and Green’s (2001) original think/no-think paradigm for motor sequences as items, thus exploring the effects of repeatedly and deliberately suppressing retrieval of motor sequences on their later recall in two experiments. Following learning, wherein participants had to associate several motor sequences with different letter cues and to also execute them in repeated trials, a think/no-think phase began. Herein, a subset of these sequences was to be executed in the same way as in the learning phase (think trials), whereas other sequences were to be deliberately suppressed in execution as well as in recollection. In such no-think trials the letters were shown, but participants were instructed to not execute the corresponding motor response as well as to additionally even try to hinder it from entering conscious awareness. Results revealed that suppressing motor retrieval impaired later memory performance for these sequences in comparison to baseline items that did not appear after their initial training. Moreover, suppression trials impaired later recall accuracy and execution speed in different ways: with higher initial training (Experiment 1), suppression impaired reaction time, but not recall accuracy; whereas lower initial training (Experiment 2) led to reduced recall accuracy. A cross-experiments reaction time analysis for suppressed sequences revealed a robust slowing of movement execution. This shows that voluntarily engaged inhibitory control processes during retrieval suppression influenced the very memory representation of these sequences, not just by only reducing their accessibility but also by slowing down their execution, once recollected.
