Working Memory Training (WMT) with a reduced Recall Accuracy Threshold (RAT): Enhancing Secondary Memory Capacity

Two-component Working Memory Training, Adaptive One-Component Working Memory Training, and Non-Adaptive One-Component Working Memory Training are three versions of a working memory training program that target both primary memory (PM) and secondary memory (SM) components of working memory. The training program includes 12 verbal and spatial simple working memory span tasks. Participants train on four common exercises and four critical exercises each day, with the common exercises rotating throughout the duration of training. The critical exercises are identical across the three training conditions, but the recall accuracy threshold (RAT) and adaptivity of the training differ between conditions. The two-component condition has a reduced RAT and adaptivity, the adaptive one-component condition has a 100% RAT and adaptivity, and the non-adaptive one-component condition has a fixed span length of two items and no adaptivity.
