I may as well link you guys to http://cube.asher.io as well. It only works in chrome though! It is a web page that I banged up in a night that we used to create the items. No instructions on it though - try drag and drop :D

Re: Help me out by taking this spatial ability test
#43Spoiler alert . . . Hm. I might have "cheated" on this. I haven't tried to imagine the actual 2D->3D transformations but instead looked for clues in the 2D images. It's a bit hard to describe - transforming the cutouts in my head so that they match (or obviously differ) in 2D while still giving the same cube. Did not submit though, since I got tired after the 4th set.
All spatial tests are able to be solved with structural techniques rather than spatial ones. We have designed this test in response to that flaw so that when it comes to the harder items it is much more difficult to do so than to use the intended mental transformation and rotation techniques.
Partially failed with me. I had to think of more and more elaborate transformation techniques over time, however, and apparently that failed for one test (I got 8 out of 9) (I really would have liked to know where I screwed up, though you may be afraid that cheating skews your results).
But, to come up with those "cheats", I had to imagine the 3D cube folding before me. Number 6 in particular had me do a more thorough analysis than most (but I still came up with a way to cheat, then used it).
Re: Help me out by taking this spatial ability test
#44Looking for opposing face pairs is the easy method, and works on most of the questions (I think 6 of the 9.)
If all the opposing pairs are the same, there are two more ways to distinguish. One is the placement of the symbols relative to each other; the chirality of the whole object. For an example, think of a six-sided die. Position it so that the 6 is on top and 2 is towards you. The left and right faces will be the 3 and 4, in either order, creating two distinct possibilities.
The other remaining distinction is the orientation of the symbols on each face. Continuing the die example, with the 6 on top and the 2 towards you, the 2 pips can have either of two diagonal orientations. Orientation creates a possibility space of 2^N * 4^M where N is the number of sides with 2-way orientation distinguishability and M is the number of sides with 4-way distinguishability. On a normal die, N = 3 since the 2, 3, and 6 are 2-way orientable, and M = 0. Some of the questions here have M > 0, specifically the arrows and hearts.
(I'm ignoring cases where rotating the whole cube creates duplicate possibilities. Consider one side with an arrow and 5 blank sides; although the arrow has 4 orientations, they are not distinguishable. I'm also ignoring the possibility of rotating a symbol in non-90° increments.)
Re: Help me out by taking this spatial ability test
#45I'm not sure it takes into consideration the orientation of the image, I was using that as a short cut - E.G. arrow points to circle and such. This made about half of them solvable by inspection in under 15 seconds for me. However the result was 1 out of 9. Using this same approach the 8th question was obviously flawed, I wasn't about to go back and try a different method at that point though.
I originally uploaded the incorrect items, of which one contained a flaw (I scored it as correct for everyone in that early group). In the easy questions you can indeed use those structural techniques, but in the harder ones you couldn't. In the 'gold standard' spatial tests that currently exist you can use these kinds of queues for almost every item very easily, which is why we introduced this method. Also, we need…
So, what is this short study for?
Re: Help me out by taking this spatial ability test
#46Darn! 8/9 This should tell you which one you got wrong, because now its going to drive me crazy.
Agreed, same here. SPOILER The consensus seems to be that 8 has more than one answer, I definitely see 8A as different from the others (arrows pointing away from each other as opposed to perpendicular), but perhaps there is another one. Brain is too tired to figure out another possibility right now; thanks for the workout :) BTW #6 I found most difficult (even more so than #9), and #7 was far too easy for its positio…
Yes, No. 8 has certainly an error. At least the version I got first, if I load the page now I get a different set of cubes.

#478/9 first try, after cheating I figured out what I missed. I swear there's something wrong with Q5, I've been staring at it for 10 minutes :)

What I have found is that the higher intelligence/spatial ability type people are able to use these types of techniques on more difficult questions. I do very well on traditional spatial tests because they are trivial with relational or structural comparison.
Here is a real challenge.. can you think of a design for a spatial ability test (that is able to be done on pen/paper) that does not allow for this type of strategy? :)

Great! Thanks for your data :D I'm glad you enjoyed it. You wouldn't imagine how many complaints we got from fellow students.

I found the easiest way to do this test was to first find something the uniquely determined the the the position and rotation of the cube. Then I would see which edges were adjacent by folding in my head. I would use this to gradually construct a

canonical 2d picture of one picture. I would then compare the others to this one.
I couldn't hold a 3d picture in memory. 2d and graphs on the other hand..
