“…Because the accuracy can vary depending on the alternatives included, it is not an easy task to adequately transform a free recall task to multiple-choice questions, while the other way around is easier. Moreover, multiple-choice questions are widely used in experimental, clinical, and neuroscience research (Luna et al, 2011 ; Arnold et al, 2013 ; Higham, 2013 ; Chua et al, 2017 ; Griffiths and Higham, 2018 ; Mangels et al, 2018 ; Martín-Luengo et al, 2018 ; Navajas et al, 2018 ; Williams et al, 2018 ; Coane and Umanath, 2019 ).
