Definition
Meaning
A principle in Gestalt psychology stating that elements sharing visual characteristics (such as shape, size, color) are perceived as belonging together.
The cognitive tendency to group similar items together, which is applied beyond visual perception to include conceptual similarity in patterns, ideas, or behaviors in fields like design, marketing, and learning theory.

Examples
By CEFR Level
- In the picture, the circles are grouped by colour because of the law of similarity.
- Designers utilise the law of similarity to create intuitive interfaces where related functions share visual characteristics.
- The perceptual segregation of the visual field, as predicated by the law of similarity, can be modulated by attentional load and contextual cues.
Learning
Memory Aids
Mnemonic
Think of sorting sweets by colour. Your brain automatically groups the red ones together and the green ones together. That automatic sorting by shared feature is the 'Law of Similarity' at work.
Conceptual Metaphor
SIMILARITY IS PROXIMITY (conceptual), GROUPING IS GATHERING, LIKE ATTRACTS LIKE.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'правило похожести' which is too simplistic. The accepted translation is 'закон подобия'. 'Law' here is scientific, not judicial, so 'закон' is correct.
Common Mistakes
- Using 'rule of similarity' in formal academic writing (though understood, 'law' is the standard term).
- Confusing it with the 'law of proximity'.
- Omitting the definite article 'the' (it's generally *the* law of similarity).

FAQ
Frequently Asked Questions
While originating in visual perception studies, the principle is now applied metaphorically to other areas like idea organisation, product categorisation, and learning.
The law of similarity groups elements based on shared attributes (colour, shape). The law of proximity groups elements based on physical closeness.
Yes, stronger Gestalt principles (like common fate or past experience) or focused attention can override grouping by similarity.
It is a descriptive psychological principle, not a universal physical law. It describes a strong, consistent tendency in human perception.
