The Gruen Effect

I just recently read something about the Gruen Effect (or Gruen Transfer) that got me thinking about how I seem to work, and wondering if the Gruen Effect operates differently with autistic people.

So before I go any further, I want to ask you – what is it like when you go shopping? How well do you stick to your plan?

Ok, onwards to the post. First of all, let’s talk about this Gruen Effect thing. I actually remember learning about it (or, well, an aspect of it) in school back in the 90’s, but I guess until I was reminded of it I didn’t really think about it since. Basically, apparently when shopping, a fairly common thing to happen is to lose track of what one is shopping for, and grabbing extra things that one sees around. Stores now are often designed to encourage this and take advantage of it. When in school, the thing that my teachers talked about was specifically grocery stores – how they are designed in many different ways to manipulate your shopping experience and encourage impulse purchases. I don’t actually know how common it is for people to grab lots of extra things, but various things I’ve read seem to indicate that it happens a lot.

What I do know, though, is how I shop. And this Gruen thing does not seem to apply to me at all. AT ALL. When I go grocery shopping, I do need to bring a written list with me. However, this is because if I don’t, I just won’t get anything, or I’ll only get a very small number of things that I can remember we need, but anything I don’t remember I don’t get. And I don’t get extras.

When I do go in with a list, I ONLY get what’s on that list. I will, maybe, get some things not written that I simply know need to be gotten every week, so I feel less need to rely on the written list to get it. But otherwise, if we need something and I didn’t write it down, I don’t get it. This has actually happened to a fair extreme a few times. Sometimes we need milk, but I forgot to write it down. When going into the store, I might remember that I need to get milk, and make a mental note to get it. If I don’t write it down immediately, though, I ultimately won’t get milk. I will walk right past the huge, impossible to miss dairy display because I am so focused on my written list that I can’t remember anything else that I might need.

What’s really telling to me, though, is what happens when Nee and I go grocery shopping together, as opposed to me going on my own. When we go together, we wind up getting a LOT more than what was on the list. Nee will see things and go “hey, that looks good!” or “we could use this!” or “hey, let’s make a dinner out of that” or whatever else. Also of note, when I am alone I never, ever, grab myself impulse candy in the checkout aisle. When Nee is with me, I sometimes will, but generally only after Nee suggests it, or I watch Nee grab candy for themself.

Oh, and we do this in defiance of typical stereotypes, as I am female and Nee is male.

So that got me wondering if there’s something about me that means I operate differently. Maybe it’s an autistic thing. I couldn’t actually find anything in my initial googling, so I’m left to wonder. Which is why I’m asking you – how does shopping work for you?
