visual manipulation, which is on the Ravens Progressive Matrices, style questions, or they are referring to spatial rotation. Spatial rotation is very clearly defined. So I'm not going to go into that much but visual, the visual logic is a bit more complex. And what it what it is composed of is a series of operations where a shape can change its pattern, its texture, its color, its frequency, its direction, and other things. And it's depending on the variety of visual logic tests, these operations will be frequent in number. And in some, some more than others basically. So in the Ravens Progressive Matrices on the infamous IQ test DK. It is common for test takers to infer a kind of movement along the answer choices. I've noticed this because I've looked at the responses that people give. And so there are people who start off with the premise that the test is going to feature more like spatial transformation across the answer choices. And then there are people who believe that the test is going to offer more spatial repetition or, or pattern manipulation. Sorry about pattern manipulation, I mean, pattern alteration, actually. And if you want another abstract challenge, try to represent the difference between manipulation and alteration using purely visual logic, it is difficult. So the difference between pattern manipulation and alteration I'm sorry, the presence of pattern alteration on the Ravens Progressive Matrices test occurs where they will, for example, include a square in the first and second column, and like not in the third one, or whatever. And then by like by frequency of the second column, and third column, you will deduce like way or the square should have been paternalistically. And that's debts accounting exercise, because you're counting the number of squares. In other kinds of tests like this, you are supposed to infer the way in which the, the way in which the item has been transformed, so like from item one to two, the square might be morphed a little bit. In, there's the texture station, so not in one, arm two, it might be filled in a little bit, and so forth. So a lot of the Ravens use more paternalistic, and for instance, rather than the transformative inferences, and so depending on a person's assumptions, walking into the sub test, that will determine how they perform on it, because of what kind of inferences they're looking for. And also what kind of verses they're aware that the test could determine are correct. But what I want to stress here is that the test that all of these things are actually sub components of other cognitive skills. So in one sense, there's a visual pattern recognition. And another there's, well, actually, there's visual pattern recognition by frequency, and there's visual pattern recognition, recognition by quality, those different things for one, but then there's the rotational ability also. And then there's counting ability, these things are very separate. And they can these things can also relate to scanning ability. So there is a large difference between rather their most people can read about as well as they can listen. But there are certain people who can listen better than could read and there's certain people who can read by they can listen. And people who can listen better think and read I'm one of those people have difficulty scanning text with high accuracy. And because the, your eyes just don't follow the text as well as you'd like. And this is not merely an issue of reading, like long textbooks. Actually, this occurs to me even at like grocery stores, I have a problem. Switching from item to item, and my eyes just like don't visually work as fast as I would like them to. With language, there's going to be things like analytical reasoning,
