# Which parts of cognitive tests are under copyright? Can test rights be purchased for modification?

(Asked by: username_0 on 2013-08-19)

what are the steps/considerations if I want to modify an exisiting Cognitive Test Battery?

1) How do I know which parts of the test are under copyright? For example, simple digit span isn't under copyright but is part of a test battery that is copyrighted.

2) If I want to develop my own set of tests, is it possible to buy over the rights of a test and make modifications from there?

**What elements of a cognitive test are copyright?**

Part of violating copyright is actually copying. So if you actually copy any specific part of the test, such as specific item wording, or images, or instructions, then you might be in trouble. Likewise, many test names if they are not generic might have a range of intellectual property protection including copyright, trademarks, and passing off.

In contrast taking inspiration from the the idea for a test and building your own seems a lot less likely to breach copyright. It's even better if instead of copying the idea for a test you are able to understand the scientific literature and appreciate that a certain type of test has been developed by many people already. You then take inspiration for the type of test from the literature rather than copying a particular test.

To follow on from your example, "digit span" is an example of a common experimental task. There are many others (e.g., simple and choice reaction time, stroop tasks, various sensory discrimination tasks, etc.). Likewise, in the case of intelligence tests, there are huge numbers of subtests or item types which are not owned by anyone in particular, such as vocabulary items, analogies, general knowledge, simple mathematical questions, and so on.

You can make tests involving these kinds of tests without having to copy any particular existing test.

Likewise with all these tests there are many decisions that the test developer needs to make including specific item content, which subtests will go together, what to call the tests, how many response options to include, how many items to retain, what difficulty to choose, and so on.

If you are serious about developing a cognitive test battery then you would need to think about these ideas. You would also want to be informed about psychometrics and the many approaches that have been adopted for creating tests of a given type. With this knowledge and a plan you would not need to copy any one test.
