I’d have to look at actual evidence to answer that question with any degree of authority, and that would take more time than I have right now, but I can sketch an answer...
My source of empirical evidence would be the Go Teaching Ladder, where you get a chance to see higher level players commenting on the inferred thought processes of more novice players. (And more rarely, novice players providing direct evidence of their own thought processes.)
Higher level players tend to recommend “light” play, over “heavy” play: a typical expression is “treat this stone lightly”.
Unpacked, this means something like “don’t treat this stone as an investment that you must then protect by playing further moves reinforcing your conception of this stone as a living group that must be defended; instead, treat this stone as bait that you gladly abandon to your opponent while you consolidate your strength elsewhere”.
“Heavy” play sounds a lot like treating a sunk cost as a commitment to a less valuable course of action. It is play that overlooks the strategic value of sacrifice. See here for some discussion.
However, this is usually expressed from an outside perspective—a better player commenting on the style of a more novice player. I don’t know for sure what goes on in the mind of a novice player when making a heavy play—it might well be a mixture of defending sunk costs, wishful thinking, heuristic-inspired play, etc.
