What are standard tests for mental visualization (image, representation) for kids? So far I know about mental arithmetics and spatial rotation tests. Is there any other way to check mental vision ability?
As an example, here's a test I've created. One has to imagine and do manipulation over the mental image:
- imagine a white square with clearly visible white borders on a black background
- now draw white vertical line in the middle of the square. What do you see now?
- now draw white horizontal line in the middle of the square. What do you see now? Which and how many parts do you see?
- now clear up the two lines you draw. Instead, draw two vertical lines which divide square vertically on equal parts, and draw two horizontal lines which divide square horizontally on equal parts. What do you see? How many parts are there?
- now use lines as guides and cut out corners of the resulting figure and remove those from pictures. What do you see? How many parts does it have?
- now attach red squares to the corners (instead of previously cut ones)
- now split the figure into 3 parts using vertical lines you've imagined before. Let the side parts glide in opposite directions and rotate 90 degrees clockwise. After rotation, merge the the parts back into one figure
- now imagine two transformations: 1) rotate resulting figure 180 degrees and 2) mirror the figure. Are the two transformations equal (do they produce same image)?
- now name colors of parts of the image after 180 degrees rotation
Here's how I'd like to interpret results:
- correct answers to all questions: child is capable for mental vis
- in the middle of test says "this is boring" or distracts: child has reduced capability for mental vis
- has problems with answering 3rd questions: child isn't capable of mental vis. This is a real problem for further education
I haven't yet tried to run this test, but I'd like to know if there are other such, which can verify a child is doing mental visualization.
