What kind of task it is
This task asks you to fold paper 1 to 3 times, punch a hole, and reason where the holes will appear when the paper is unfolded.
Folds can be vertical, horizontal, or diagonal, and punch shapes can vary, such as circles or triangles. As the number of folds increases, the final arrangement of holes becomes more complex.
The sequence of folding, punching, and unfolding has to be followed mentally. The core of the task is not physically folding paper, but predicting the unfolded state after the paper has been folded.
What it measures
Within the five domains of BrainTypeIQ, this is one task that measures Gv (visual-spatial processing).
Within Gv, it especially measures visualization, or the ability to simulate how a complex pattern will look after several transformation steps.
- Paper Folding follows the sequence of fold → hole → unfold
- The other Gv task, Visual Puzzles, handles the relationship between parts and the whole, or decomposition and reconstruction
This is different from what is often called mental rotation, or the ability to rotate a figure in the mind. Paper Folding is not a simple rotation task. It measures the ability to handle the change from folding through unfolding in the mind.
Paper Folding is not a WAIS subtest, but it is a task format used in research on spatial visualization. In BrainTypeIQ, the folds are shown on screen.
For Gv overall, see what visual-spatial processing (Gv) is.
When the score is higher
When the Paper Folding score is higher, it is easier to track how positions change from folding to unfolding. Even as the number of transformation steps increases, the intermediate state can be held while moving to the next transformation.
This ability relates to handling figures and arrangements in the mind. It is close to processes such as thinking about part positions from a finished shape, imagining a solid form from a net, or following changes in diagrams and structures.
When the score is lower
Even when the Paper Folding score is lower, it cannot by itself judge visual-spatial processing as a whole. Several factors overlap in the score.
- High load from following the folding sequence - The change from folding through unfolding has to be held
- High load from holding multiple folds - With two or three folds, intermediate states have to be kept
- High load from predicting final positions - The unfolded state after the hole is punched has to be handled mentally
Paper Folding makes Gv easier to see, but it does not represent all of Gv. The ability to handle part-whole relationships is more likely to appear in Visual Puzzles, while finding rules in figures can also appear in Matrix Reasoning.
BrainTypeIQ is an online IQ test with 9 tasks, including Paper Folding, that shows overall IQ and the five-domain cognitive profile. Reading several tasks together, rather than one task alone, makes the meaning of the result easier to see.
