Subclaims¶

q3 i2 Sleep-deprived adolescents tended to have higher theta power, indicating lower tonic arousal, than when healthy-slept; the difference was marginal (p=.08). → Beebe 2010

Evidence¶

Beebe 2010¶

Beebe, D. W., Rose, D., & Amin, R. (2010). Attention, Learning, and Arousal of Experimentally Sleep-Restricted Adolescents in a Simulated Classroom. The Journal of Adolescent Health. https://doi.org/10.1016/j.jadohealth.2010.03.005

q3 · i2 · causal · r2

EEG-monitored subset (n=8) of the counterbalanced sleep manipulation; tonic arousal was operationalized as C3/A2 theta (4–7 Hz) spectral power, log-transformed, with higher theta power reflecting lower arousal. Participants "tended to have higher theta power, t(7)=1.5, p=.08, d=.53".

"tended to have higher theta power, t(7)=1.5, p=.08, d=.53"
