As someone who learned how to fish (and crab) at a young age, and did so for many years, I never once thought about the perception involved with hooking a fish (or crab). However, overtime, I became very attuned to even the slightest tug of the line, and knowing that opportune moment to pull back and start reeling in.
I thought even less about the perception involved with casting a line. This is a skill I do not specifically remember being taught, but one that I seemed to get the hang of quickly and one that stayed with in the long-term. That said, I found it very interesting that in Rosenblum's book, that Rick Passek stated that women typically pickup on casting lines much quicker than men do. This reminds me of one experience with two of my male cousins, when they were showing off casting their lines, but weren't so great at it (whereas I, who hadn't done it for years, was able to successfully cast a line.)
