Paired samples t-tests comparing Control to Stress Montreal Imaging Stress Task (MIST).
Measure | Control (M ±SEM) | Stress (M ±SEM) | n | t | p |
---|---|---|---|---|---|
Response time | 2.91 ± 0.02 | 2.21 ± 0.02 | 53 | 17.88 | <0.001 |
% Correct responses | 85% ± 1% | 54% ± 0.1% | 53 | 23.06 | <0.001 |
SCR | 0.42 ± 0.05 | 0.94 ± 0.08 | 44 | -7.34 | <0.001 |
Stress rating | 15.55 ± 0.59 | 25.98 ± 0.59 | 40 | -8.82 | <0.001 |
HR | 69.38 ± 5.54 | 76.06 ± 5.54 | 40 | -5.15 | <0.001 |
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 13 participants. Seven participants had errors in HR data acquisition, and six participants had HR with low SNR. One participant had errors in SCR data acquisition, and 10 did not have any SCRs above 0.05 μSiemens. SEM reflects within subject standard error of the mean.
