I recall a paper on skills retention (desperately attempting to locate it), which considerd the learning process.
Initial training develops the basic skills up to a 'novice' standard; the student is safe but requires more time to link the basic skills together for a situation. Knowing what to do, but not initially knowing when - situation assessment.
With continuing practice, expert behaviour emerges which links the skills together; the skill of choosing a skill set for a given situation. Know when; skills of situation assessment and skill selection. Experts require less deliberation and are able to quickly match skills to situations. Knowing both what to do and when to do.

Discussion re extensive automation use, reversed the learning process. Without manual flight practice pilots were still able able to maintain the basic flying skills (how to) but the 'when to skills', matching skill sets to scenarios degraded. The expert skills were lost first, lack of anticipation, longer to understand situations, and the ability to link basic skills with situations; but they could still 'fly' the aircraft.

The following is related:-
"Hand-eye skills (instrument scanning and manual control), if initially well learned, are reasonably well retained after prolonged use of automation.
Cognitive skills, such as navigation and failure recognition and diagnosis, are prone to forgetting and may depend on the extent to which pilots follow along when automation is used to fly the aircraft."

Thus for a 'go-around on the ground' vs 'takeoff', the required behaviour might be obvious to an 'expert' pilot, but with degrading skills, it would be more difficult to relate the basic skills to the situation; even more so if the situation is surprising.
i.e. 'Automatic dependent' pilots may have difficulty in assessing the 'on ground go-around' situation as similar to a 'take off' situation, even though they have the basic skills for both.
