Incremental correlations between amb-WMC, lab-WMC, and Gf. After one session, amb-WMC was significantly correlated with lab-WMC and Gf. After 7 sessions (<2 days of the measurement burst or approximately 21 minutes of total testing) amb-WMC reached a maximum level of correlation with the laboratory-based tasks (r>0.6 with lab-WMC, r>0.5 with Gf). WMC: Working Memory Capacity; Gf: fluid intelligence.
