Log ratios gave a more negative age correlation than time differences for switch cost in 155 ds005270 adults
We tested how score scale changed the age relation for local switch cost in OpenNeuro ds005270 version 1.0.0. The sample had 155 adults aged 20 to 86. We used correct responses with recorded times from 150 to 3000. We treated these values as milliseconds because the source did not state a unit. The age correlation was 0.0115 for switch-minus-repeat time and -0.1049 for the mean log ratio. Their paired difference was 0.1164, with a 95% interval of 0.0769 to 0.1579. The main age models included recorded sex. Both switch-cost age intervals included zero. A shorter response window gave a more negative log-ratio slope. The measured age association depended on score scale and trial rules. The data cannot identify an aging cause or a brain mechanism. The package preserves fixed source files, provenance, a local plan, code, all reported interval draws, and figures. Independent checks passed. All 29 result files and four figures matched in a second run.
