Abstract & diagrammatic reasoning: the pattern playbook
Abstract reasoning (also called diagrammatic or non-verbal reasoning) tests your ability to spot rules in visual sequences. The good news: there are only about six pattern families, and once you know them, you will recognise them instantly. For the broader logic method, use the logical reasoning guide; for a family-by-family drill list, use pattern families.
- Abstract reasoning improves when you classify the pattern family before solving.
- Most questions combine one visual rule with one counting, shading or movement rule.
- If a rule does not predict every frame, discard it quickly.
- Timed review should label the missed family, not just the missed question.
Pattern speed needs repeated timed exposure to the same rule families. Start logical practice
What to focus on first
| Focus area | Why it matters | Best drill |
|---|---|---|
| Movement | Position changes are fast to verify. | Track one distinctive object across frames. |
| Count | Dots, sides and intersections are common hidden rules. | Count the least obvious feature first. |
| Shading | Fill cycles often run alongside a movement rule. | Compare the same position across frames. |
| Layering | Higher-difficulty items combine or cancel shapes. | Check whether frames add, subtract or overlap. |
Common traps
- Solving from the first visible change. The obvious change may be a distractor.
- Ignoring two-rule patterns. Many options satisfy one rule but fail the second.
- Confusing reflection and rotation. Use asymmetric details to tell them apart.
How to practise from here
Do ten questions where you only name the pattern family, then ten where you solve fully. Separating classification from solving trains recognition speed.
The six pattern families
1. Movement (translation)
An element moves across the frame — left to right, top to bottom, or diagonally. Track its position in each frame and extrapolate.
2. Rotation
An element rotates by a fixed angle (45°, 90°, 180°) between frames. Sometimes only part of the figure rotates while the rest stays fixed.
3. Element count
The number of shapes increases or decreases by a fixed amount. Variants include alternating +2, −1 patterns or Fibonacci-like sequences.
4. Shading / fill
Shapes cycle through fills: empty → striped → solid → empty. Or fills toggle between black and white in a specific order.
5. Layering / overlap
Shapes are stacked. The rule might be that the top shape moves to the bottom each frame, or overlapping regions change colour.
6. Arithmetic / logical operation
Frame 1 + Frame 2 = Frame 3 (union of shapes), or Frame 1 XOR Frame 2 = Frame 3 (elements present in one but not both).
Rotation: 4 × 45° = 180° from Frame 1 (so the triangle is flipped). Dots: 2 + 4 = 6 dots inside a 180°-rotated triangle.
This is a two-rule pattern. Always check if multiple rules operate simultaneously.
Common traps
- Distractor elements. Some shapes are static decoration. Focus on what changes between frames.
- Two simultaneous rules. E.g., rotation + shading change. Solve each rule independently.
- Reflection vs rotation. A 180° rotation looks the same as a horizontal reflection for symmetrical shapes. Check with asymmetric details.
How to review abstract reasoning misses
Do not stop at the correct option. Write the family you missed and the first false hypothesis you held too long. If you keep missing movement, drill grid movement. If you keep missing count, count sides, dots and intersections before looking at shading. If your invite names SHL, move next to SHL inductive reasoning; if it names AON, use AON inductive logical.
Source notes
forge checks abstract-reasoning guidance against provider material including SHL’s cognitive assessments overview and Aon’s online assessment preparation page. Provider names change, but the review habit is the same: name the missed family and drill that family directly.

Start practisingFrequently asked questions
Is abstract reasoning the same as logical reasoning?+
It is one common form of logical reasoning. Abstract reasoning usually uses visual patterns, sequences or matrices rather than written premises.
What pattern families should I learn first?+
Start with movement, rotation, count, shading, layering and arithmetic operations. These cover most visual reasoning questions.
How do I get faster at abstract reasoning?+
Classify the pattern family before solving, test one hypothesis across all frames, and drop it immediately if one frame breaks the rule.
