Hang in there for this one — it’s going to seem plenty obvious to many people but this is just the way my brain does/does not work The obvious is sometimes too large for me to see. It’s a pretty common phenom in humans. There are studies to prove it. For example, at one school, test subjects viewing a film/video did not see a person in a gorilla suit in the middle of a crowd of humans. In another studies, pilots in a test situation did not see another airplane minding its own business on the tarmac.
So if I can tell my horse is spooking at something while I’m riding and I can tell by observation of ears and by her body language (she’s turning herbody away from a sudden patch of sunlight on the floor of the arena but obviusly paying a lot of attention to it with her senses), then I should go ahead and give her a command of some kind to get her mind off of the scary thing and back on the work.
In other words, I should be proactive, right? Not just sit and wait or sit and panic, but do something, yes?
