Using Caffeine Pills for Performance Enhancement. An Experimental Study on University Students' Willingness and Their Intention to Try Neuroenhancements.

Provision of experimentally manipulated evidence about prevalence lowered regression weight for the associations between ‘attitude’ and ‘willingness’ in condition A by 45% relative to the control group, which did not receive any prevalence information; a similar effect (lowered regression weight by 40%) appeared as a statistical trend in condition B ( Figure 2B ; condition A: β stand. = 0.31, p < 0.01; condition B: β stand. = 0.34, p < 0.01; condition C: β stand. = 0.57, p < 0.01).
