“…This occurred when the preceding item was a high rather than a low frequency word or word pair Ward et al, 2003;Cox et al, 2018;PEERS -Healey & Kahana, 2016), was a pseudo-word that was experienced more frequently in training prior to the study list (Reder et al, 2002), was a word or word pair that was repeated on multiple trials (Buchler et al, 2008) or lists (Aue et al, 2017), or was a word pair that was supposed to be forgotten, rather than remembered (Marevic et al, 2017;Popov et al, 2018). This effect was a parametric function of word frequency (Cox et al, 2018;PEERS -Healey & Kahana, 2016), it accumulated when more of the previous items during study were weaker Buchler et al, 2008;Reder et al, 2002;Marevic et al, 2017;Popov et al, 2018), it decreased when the lag between the current and the prior item increased (Cox et al, 2018;Buchler et al, 2008;Marevic et al, 2017;PEERS -Healey & Kahana, 2016;Popov et al, 2018), and it was bigger when the current item was weaker itself (Buchler et al, 2008;Ward et al, 2003). Importantly, these results cannot be due to other mechanisms such as rehearsal or attentional borrowing (Popov et al, 2018).…”
