Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 Medium-sized effects for eyes-closed and head-down behaviors (d=.49–.50) did not reach statistical significance, likely due to limited power. → 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 · r1
Secondary coded behaviors in the video-monitored subset (n=8): yawning, eye rubbing, eyes closed, head on table for ≥3 consecutive seconds. The authors report "the medium-sized effects for “Eyes Closed” and “Head down” (d=.49–.50; Figure 1)" were not statistically significant.
"Although not statistically significant, the medium-sized effects for “Eyes Closed” and “Head down” (d=.49–.50; Figure 1) may have reached significance in a larger sample."
