An exploratory study of EEG brain wave patterns while solving puzzles

This is a presentation made by Nathan Curtis, a senior at Davis High School (Davis, CA) as part of the "Mindseum" panel at the annual 2014 World Future Conference of the World Future Society (July 21, 2014) in Orlando, FL: http://www.wfs.org/worldfuture-2014/worldfuture-conference-sectors/designing-curating-and-exploring-mindseum

  • 4. The Puzzle & Setup • Ceaco Kids Dinosaur Puzzle • 100 pieces • 11” by 14” end result 1.5” x 1.5” • Took too long for subject to complete entire puzzle • Modified setup so that the borders were already in place • 64 Border Pieces; Subject must place 36
  • 5. • Neurosky Mindwave to measure EEG brain waves • WujiBrainwave & WujiTech to record and graph the data • Took 6 recordings of each subject: • First three were taken while the subject had no idea what the puzzle depicted • 12 pieces per measurement: Pieces 65-76 (Beginning), Pieces 77-88 (middle), Pieces 89- 100 (end) • Pieces 1-64 already in the border • Last test was taken once subject knew what the image looked like. • They were allowed to use a complete image as a reference the second time. • Ages range from 18-76

  • 13. Results: Alpha/ Beta/ Gamma Halfway Through: Pieces 65-76 With Reference (2nd Time) Without Reference (1st Time) Alpha Beta Gamma Jim (Age 54) Allan (Age 78)
  • 14. Conclusion: • Attention • When beginning a puzzle, attention is highest when reference is present • When finishing a puzzle, attention is highest during the first time • Relaxation • Presence of a reference does not change one’s relaxation • Relaxation varies from person to person • Most likely just differences in the individual • Alpha/ Beta/ Gamma • Among younger subjects, alpha/ beta/ gamma waves change dominance • Among older subjects, gamma is highest while alpha is the lowest
  • 15. Questions: Why are gamma EEG waves dominant for older subjects? What characteristics of an individual would cause them to be more relaxed/ attentive while completing puzzles? Why do alpha/ beta/ gamma EEG waves correlate so strongly?
