Response time (in seconds) indicates time following math problem presentation to response selection with a button press. HR, Heart Rate; SCR, Skin Conductance Response. Stress ratings were not collected on 12 participants. Thirteen participants had errors in HR data acquisition, and 26 participants had HR with low SNR. Nineteen subjects did not have any SCRs above 0.05 μSiemens. SEM reflects within subject standard error of the mean.
