> One thinks in words
No. There are people who believe they think in words, because they haven't bothered to examine the question, but there are no people who think in words.
Think about the number of people you've ever seen do a double take at the idea that "I don't know how to put this into words".
I bet you can answer all of these at a moment's notice, but where does your answer come from? Have you ever sat down and tried to reason out which one you like more? Or do you just 'know' the answer and then 'come up' with the justification afterwards?
People can think in words, but it's certainly not their only way of thinking. I think the thinking in words is kind of like "thinking on paper" where you're trying to explicitly reason through something. The thinking process itself seems to be something on a deeper level.
I'm sure you think that way too, you probably just layer a narrative over it. The sibling comment about picking up a spoon is an example I sometimes use - see yourself walk to the kitchen, move your hand to open the drawer, pick up a spoon, pour the tea, scoop the sugar. I can describe them but it's not natively linguistic to me.
I'm hell at rearranging furniture or putting together an engine, not so good at positive self talk.
From that perspective, the experience of thinking in words or pictures is distinct from actually thinking in words or pictures. Saying one thinks in one of these ways seems to be saying what they identify thinking with.
For example, I don't usually think of fantasy as thinking. If I day dream, I wouldn't say I am thinking, but that is fairly visual. To what degree am I saying something about myself vs my identity if I say I do or don't think in words given that context?
Relatedly, I've noticed that when it comes to remembering something, it is not 'I' that remember. Rather 'I' set up mental cues and direct focus, which then hopefully causes the memory to be placed within my awareness. This happens below the level of direct experience. But I might say I failed to remember, taking responsibility for something that 'I' - the part separated from the automatic functions of the body - did not do.
So I'm suggesting statements about words vs pictures are about ego, metaphor and meaning-building, and not about actual mechanisms or communicating actual differences in the experience of thinking.
It can be difficult to talk about these things because such conversations implicitly occur between our identities, not between who we actually are - something beyond our grasp - and the noise this introduces is something I don't know how to surmount, or if it can be surmounted.
I've always thought of my mental model as an endless conversation with myself, but I think the more fitting description would be a "smooth" series of thoughts which only materialize into language when I explicitly focus on those thoughts as their own thing.
I do also think visually for things that have a visual component though.
I have some experience with a meditative/dissociative state in which that monologue - which I think of as the "narrator process" - can be observed as just one of many mental subsystems, neither containing the whole of my consciousness nor acting as the agent of my will. The narrator merely describes the feelings which arise in other mental components and arranges them, along with the actions I take, into some plausible linear causal sequence.
Minds differ in many ways, and perhaps one way your mind and mine differ is that words flow quickly for me and do not feel slow or limiting; so I suppose I am easily fooled into perceiving that narrative as the medium of thought in itself. It had not occurred to me to describe the activities of the other mental subsystems as thoughts, but why shouldn't they be? And now I have a better guess at what it might be like to experience the world in a different way. Thank you!
