Procedures are designed to do things always at the same time, triggered by something else. The human brain is great at making those connections. For example, on takeoff the pilot monitoring watches the instruments and reports "positive rate" (means "we're climbing from the runway in a stable manner"), as pilot flying you always command "gear up" at that point. It is quite common in simulator practice to get an engine failure right after takeoff, and the most made mistake is forgetting to command gear up, because you're handling the emergency right at the moment you would normally do it. Luckily (as described in the article) you would normally run a checklist after any of these events, and usually that makes you catch the mistake.
