I’m not quite sure how to describe this perceptual phenomenon, except by examples. It may appear at first that I’m talking about confirmation bias, but it’s not that, or at least not entirely that.
I find that if I’m searching for some specific type of thing that after a while, I can hand over the process of looking to some mental process other than the one that is consciously at the forefront of my attention - it’s as if I can train my visual system to notice a specific kind of thing, then leave it alone until it alerts me with a possible match.
Examples:
Walking along a beach, looking for fossils, it’s incredibly tiring to scrutinise every single candidate pebble consciously and thoughtfully - after a while, my eyes kind of glaze over and I start thinking about something else, except when an unusually-patterned object (often a fossil) enters my (wide) field of vision and I seem to be shaken to my senses to look at it.
Last year, I decided I would pick up every bit of dropped money I came across and would use this to buy lottery tickets (I won nothing) - this year, I’m doing the same, but saving up the money to fund this year’s Christmas lunch (details here).
Now that I’ve been doing this for some months, I feel that I hardly need deliberately look for coins - indeed, in many cases, I’ll be walking along and there is what I can only describe as a nearly palpable ‘tug’ on my eye, pointing it at a dropped coin on the floor.
Now obviously those sought objects have to be there to be found, so I’m not arguing for any kind of mystical ‘seek and ye shall find’ phenomenon.
And I also feel that it’s not just confirmation bias - I really do seem to find more of the sought objects by ‘getting my eye in’, then not really focusing on the search, than I would if I concentrated all of my attention on the task (which seems to narrow my attention, which I think makes me miss things at the periphery of my view).
Now obviously, I’m describing what this feels like from the inside - and I don’t really have any idea if there is in fact something quite intensive - and more intensive than a conscious search) going on without my awareness of it, but in summary, it does seem to me that I can train my perceptual system to notice certain specific things, then leave it alone until it finds one.
Am I talking any kind of sense here? Has this phenomenon been documented at all and does it have a name?
