Attribution

In art, attribution is the judgement by experts as to the author, date, or other aspect of the origin of a work of art. Works "attributed" to an artist are more firmly believed to be theirs than those "ascribed".

Attribution can also mean:

• Attribution (copyright), a concept in copyright law requiring an author to be credited
• Journalism sourcing (or attribution), a journalistic practice of attributing information to its source
• Attribution (psychology), a concept in psychology whereby people attribute traits and causes to things they observe
