Cognitive Skills
What This Section Tests
Cognitive Skills measures reasoning and pattern recognition: logic puzzles, spatial reasoning, classification, sequencing, and deductive inference. The content is less about memorized facts and more about applying rules systematically.
Concepts to Know
- Deduction: from general rules to specific conclusions. If all A are B and all B are C, then all A are C. This is valid; reversing it is not.
- Pattern recognition: track changes in shape, size, position, shading, and rotation across a sequence.
- Spatial reasoning: mentally rotate or fold figures. Track one feature at a time.
- Logic grids: use a table and mark eliminated possibilities to narrow answers.
- Classification: identify the shared rule among items and find the outlier.
Traps to Watch
- Reversing a conditional. "If it rains, the field is wet" does not mean a wet field implies rain.
- Assuming only one cause. Many puzzles have multiple valid setups; use all clues before deciding.
- Overlooking one changing feature in a pattern (e.g., counting sides but ignoring rotation).
- Choosing the first plausible answer without testing every clue.
Rule of Thumb
For any logic puzzle, write down the clues and eliminate possibilities one at a time. For visual patterns, isolate each feature - shape, then size, then position - and describe its rule separately.
Worked example: All roses in the garden are red. All red flowers in the garden were planted by Mia. Which must be true? (A) All flowers Mia planted are roses. (B) All roses in the garden were planted by Mia. Chaining the rules: roses → red → planted by Mia, so B follows. Choice A reverses the logic and is not guaranteed.
Slow down on setup; a clear table or list makes the answer nearly automatic.
