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 i? SART-CO performance deteriorated markedly at BAC 0.048% and then changed little across the range up to 0.10%. → Dry MJ 2012

q3 · i? · causal · r2
Post-hoc comparisons in the 56-participant experiment showed SART-CO errors increased at the lowest dose and then plateaued; the discussion attributes this to sensitivity to disinhibition plus "a ceiling effect, with insufficient trials on which a response should be withheld".
"SART-CO performance deteriorated markedly at BAC 0.048% but changed little thereafter across BAC range 0.048% to 0.10%."

Related Claims¶
- The authors conclude Inspection Time has strong potential as a single marker test sensitive to the time course of alcohol intoxication — related
- Only SOPT, IT and SART-CO showed significant impairment at the lowest blood alcohol concentration of 0.048%, with large effect sizes (d = 0.76, 0.65 and 1.06) — related
- Acute alcohol produces a significant main effect on performance on most cognitive tasks, with partial eta-squared effect sizes from 0.07 to 0.37, but not on TSP or SART-OM — related
- TSP (complex spatial problem solving) and SART-OM (vigilance for frequent events) showed no significant alcohol effects, an outcome the authors report as unexpected — related
