You can read the original description of the apparatus here:

It's a pendulum which is released (either silently or with a click), and a button for the subject which records the angle at which it was pressed.

It doesn't sound like they actually compared apples to apples by performing the same test as a modern replication of results though.

A similar apparatus is not named or sited, when noting the modern equivalent. Does that matter? Couldn't there be side-effects for measure reation time to different stimuli?

Also, did modern 1941 measurements operate with the benefit of newer advancements, such as high-speed cinematography to produce objective slow-motion footage?
