Justify your alpha

Daniel Lakens, +98 more
TL;DR: In response to recommendations to redefine statistical significance to P ≤ 0.005, it is proposed that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.
Journal ArticleDOI

Response perseveration and ventral prefrontal sensitivity to reward and punishment in male problem gamblers and smokers

TL;DR: In this paper, the authors found that gamblers are associated with response perseveration and abnormalities in reward and/or punishment sensitivity in the ventral frontostriatal circuit, and that these effects are independent of the dorsal frontal cortex.
Journal ArticleDOI

Behavioral and neuroimaging evidence for overreliance on habit learning in alcohol-dependent patients

TL;DR: This is the first human study to provide experimental evidence for a disturbed balance between goal-directed and habitual control by use of an instrumental learning task, and to directly implicate cortical dysfunction to overreliance on inflexible habits in AD patients.
Journal ArticleDOI

Mega-Analysis of Gray Matter Volume in Substance Dependence: General and Substance-Specific Regional Effects

Scott Mackey, +59 more
TL;DR: The results indicate that dependence on a range of different substances shares a common neural substrate and that differential patterns of regional volume could serve as useful biomarkers of dependence on alcohol and nicotine.
Journal ArticleDOI
