“…In order to compare selectivity between groups and across grids, we used hierarchical linear modeling (HLM) to analyze item-location recall accuracy as a function of item value. HLM has been used in previous studies investigating memory selectivity (Castel, Murayama, Friedman, McGillivray, & Link, 2013; Middlebrooks & Castel, 2017; Middlebrooks et al, 2017; Middlebrooks, McGillivray, Murayama, & Castel, 2016; Middlebrooks, Murayama, et al, 2016; Raudenbush & Bryk, 2002). The post-hoc binning of items into low, medium, and high value groups may not accurately reflect participants’ valuations of to-be-learned stimuli (e.g., Participant 1 may consider items with values 6–10 to be of “high” value, while Participant 2 may only consider items with values 8–10 as such).…”
