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.

q2 i? The felt urge to act occurs approximately 300 ms after brain-activity changes associated with voluntary action first appear. → Frith Chris D 2012

q2 · i? · review · r2

The review reports Libet et al.'s finding (as cited) that when participants lift a finger at will and clock the urge's time, the urge is dated roughly 300 ms after readiness-potential onset, consistent with studies showing awareness hundreds of milliseconds after response initiation.

"the time of the urge was found to occur approximately 300 ms after the first appearance of the changes in brain activity associated with a voluntary action"
