The ds003823 95 percent age contrast interval included zero for ordered emotional recognition with person and shared picture draws

We tested an age contrast in emotional recognition in OpenNeuro ds003823, release 1.3.5. The study used 105 younger adults, 60 older adults, and 72 shared picture IDs. We assumed the response order Remember > Know > New. The older minus younger contrast in positive minus negative AUC was -0.010333. Its 95 percent resampling interval was -0.056191 to 0.033933 when both people and shared pictures varied. The interval did not establish a larger older score or equivalence. Shared picture and person draws increased bootstrap standard deviation by 59.37 percent compared with person draws alone. This is a reanalysis of one cohort. The package provides a reusable score function, a proof, source tables, provenance, draw counts, and independent checks. A fresh-source rerun matched all 57 main result files by hash.
