The mean task switch cost is larger with short cue intervals in 114 ds000030 CONTROL runs.

In public scanner event tables from OpenNeuro ds000030, the mean task switch cost was larger with short than long cue-stimulus intervals in 114 selected CONTROL runs. The SHORT-minus-LONG difference was 82.73589678604132 ms (95% participant bootstrap interval: 52.97939548039778 to 113.77742720604522 ms). The analysis used recorded correct responses, equal weights for the two congruency groups, and equal weights for participant contrasts. The difference remained positive in the reported sensitivity analyses. This is a conditional association in selected recorded trials. Cue lengths differed across conditions, trial position and preceding image features were not controlled, and the result does not show that cue interval caused the difference. It does not establish a general preparation effect, neural mechanism, clinical difference, individual reliability, or result for later dataset versions.
