Pattern Recognition

Pattern Recognition questions show a grid or matrix of changing symbols and shapes, requiring you to find the underlying rule (like shifts in shading, line counts, or rotations) to predict the missing piece.

Fundamental Principles

Incremental Shifting

A progression rule where a shaded zone or internal icon steps forward through a shape's corners or segments in a consistent direction.

Essential Formulation Tips

  • Track just one part of the shape at a time (like only following the black dot or only counting the outer lines) across the grid rows to figure out its specific rule.
  • Look for simple math patterns across the rows, such as 'Column 1 shapes plus Column 2 shapes combine to equal Column 3'.

Shortcut Execution Techniques

  • The Geometric Boolean Test: Check if the third column is created by combining the first two columns using an XOR logic rule (where overlapping lines cancel out and disappear, leaving only unique lines behind).

Contextual Inquiries (FAQs)

Q: What are the most common rules used to change patterns in these grids?

A: The most common rules are clock-like rotations (45 or 90 degrees), shapes growing or shrinking, line counts changing (+1, -1), or color shading flipping back and forth.
