Catawba Valley Community College's brain-dominance quiz, the BuzzFeed brain-dominance quiz and the Sommer + Sommer 30-second brain test are brief assessments to help someone determine if he is left or right brain dominant.
The Catawba Valley Community College quiz is more of a questionnaire. Test-takers grade their own answers and choose their potential degree of brain dominance from a list of corresponding scores and descriptions. The quiz is located at CVCC.edu.
The BuzzFeed quiz and the Sommer + Sommer quiz are both online and interactive, and the latter requires approximately one minute to complete. Each quiz can be found at BuzzFeed.com and Braintest.Sommer-Sommer.com, respectively, as of 2015. Neither test offers an explanation of the methodology its composers utilized, and results for the same individual may vary from test to test.
