When is it better to think without words?

My wife was confounded when I told her I don't think in words. For her, it's a one to one correlation.

She had assumed that all people think in this mode. I had assumed that all people think in "thoughts" and went through a separate step to articulate them.

Made both of us aware of a difference in people.

I don't feel vibrations or sensations though, and I definitely don't think in images. I only have a thought level, and it's very independent of any external presentation.

You sound a little like me. I wasn't aware people thought like that until my partner told me her thoughts took the form of a constant stream of well-formed English. My default mode of thinking isn't natural language (though I can force myself to think this way, it's laborious, as the article mentions), nor images (I struggle with visualization), but more like abstract sequences of both logical connections and intuitive feelings.

Adding a data point here for posterity, in hopes that someone researches this topic deeper. I recognise myself from the above, apart from "intuitive feelings" as I don't quite get what shi.. the person meant by that. My mother noted that from a very young age I was fascinated by books and indeed did an unreasonable amount of reading growing up. My sibling thinks with words. Visualisation of real things is a challenge for me, but I think I'm reasonably adept at solving more abstract things (e.g. mechanical linkages) in a somewhat visual-adjacent way that I call my "imagination". This extends to memories, as if you were to task me to picture a dog, I would feel much more comfortable picking a non-existing, imagined dog than any the dogs that I've actually seen or met, such as family members' pets. I do some painting and could wireframe-sketch this imagined subject for you and "fill in the blanks", but trying to remember any actual moment spent with those beasts is laborious and results in something akin to one-frame flashes that are immediately gone and can't be recalled at will. Inadequate memory formation/recall have caused me grief, but I have no trouble remembering for example number sequences.
