Subclaims¶

q3 i2 At BAC 0.048% only SOPT, IT and SART-CO showed significant effects, with large effect sizes d = 0.76, 0.65 and 1.06 respectively. → Dry MJ 2012

Evidence¶

Dry MJ 2012¶

Dry MJ, Burns NR, Nettelbeck T, Farquharson AL, White JM (2012) Dose-Related Effects of Alcohol on Cognitive Functioning. PLoS ONE 7(11): e50977. https://doi.org/10.1371/journal.pone.0050977

q3 · i2 · causal · r2

Post-hoc comparisons at the +60 minute test-point (target BAC 0.048%) in the 56-participant mixed-design experiment found significant alcohol-control differences only for SOPT, IT and SART-CO, with printed effect sizes d = 0.76, d = 0.65 and d = 1.06 respectively.

"For only three tasks (SOPT, IT and SART-CO) was there a significant effect at the lowest blood alcohol concentration of 0.048%."

Discussion¶

Related Claims¶

• 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 — a broader claim this one bears on
• The authors conclude Inspection Time has strong potential as a single marker test sensitive to the time course of alcohol intoxication — related
• SART-CO errors rose sharply at BAC 0.048% but changed little thereafter across the 0.048% to 0.10% range, with a suspected ceiling effect — 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
