“…To do so, we defined a ''learning phase" and a ''steady state phase" by using the procedure developed by Pailhous and Bonnard (1992) and used in previous studies (Giraudo & Pailhous, 1999;Sarrazin, Giraudo, Pailhous, & Bootsma, 2004;Sarrazin, Giraudo, & Pittenger, 2005; Berberian, Sarrazin, & Giraudo, 2007;Sarrazin, Tonnelier, Berberian, & Giraudo, 2008). The learning phase was considered to be complete when performance had stabilized, that is, when there was no further improvement in accuracy over several trials.…”
