Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Switching between tasks requires a measurable amount of time to refocus, as evidenced by established cognitive switch costs.

The analysis

The claim is supported by multiple psychological and technical studies investigating task-switching paradigms, which consistently document cognitive switch costs and longer response times when transitioning between different tasks.
