Subclaims¶

q3 i? TSP and SART-OM failed to show significant effects of alcohol intoxication at any dose level. → 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 · i? · causal · r2

In the 56-participant experiment, the TSP main effect was non-significant (F = 2.55, p = 0.11) and SART-OM near zero (F = 0.04, p = 0.83); the authors call the failure unexpected and note comparable null results in prior work.

"The failure of TSP and SART-OM to show any significant effects was unexpected, although other researchers have reported null results at BAC 0.048% [82] and for BACs between 0.059 to 0.067 [83], for similarly complex tasks involving higher order cognitive processes."

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 — possibly the same claim (merge candidate)
• 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
• 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
