Correct inanimate choices took longer after 50-pixel cursor departure in two tasks

Correct inanimate choices had a longer mean time after cursor departure in two public tasks. We analyzed the image and word tasks in OpenNeuro ds003766 version 2.0.3. The main analysis used 18,630 correct trials from 31 people. Valid main records lasted 0.2 to 3.0 seconds. Departure was the first recorded cursor point at least 50 pixels from the fixed start. The adjusted difference after departure was 44.3 ms. The person bootstrap 95% interval was 32.5 to 56.3 ms. The total recorded time difference was 49.3 ms. Both tasks had positive effects after departure. All eight planned sensitivity checks kept a positive mean and an interval above zero. A source audit found that the stored response time ends at feedback display onset. The main endpoint was the final cursor sample. The package preserves exact compressed source tables, source code, a local analysis plan, new code, trial records, results, and retrieval instructions. Independent calculations and a full rerun verified the results. The evidence applies to correct choices in this fixed sample and item set. Cursor departure is an operational event. The result does not separate decision time from motor time or identify a brain mechanism.
