Figure 1:

A) Image of the Paired associates Learning task in BHR. Note. During the first part of the PAL assessment, participants are shown boxes configured in a circle (A1). In the following part, the boxes are “opened” in a randomized order one-by-one, displaying either a pattern or an empty box which the participant needs to remember (A2). Next, the patterns are displayed in the middle of the screen one at a time and the participant needs to indicate the box in which the pattern was located originally (A3). B) Screenshot of the BHR task list showing the location of PAL named “Pattern Location Challenge”. C) PAL First Attempt Memory Score and PAL Total Errors Adjusted distributions. PAL First Attempt Memory Score is the number of times a participant chose the correct box on their first attempt when recalling the pattern locations. PAL Total Errors Adjusted accounts for adjusted errors for all 2-12 pattern levels regardless of whether the participant reached the 12-box level or not.
