Spatial Problem Solving
Understanding action in space
. Based on the cortically-couple computer vision project of Columbia University LIINC. Using BCI tech and EEG analysis.
The current experimental design incorporates puzzles in the form of being utilized as a visual stimulus. 165 solvable and 165 unsolvable puzzles were chosen and classified into 3 levels of difficulty (easy, medium, and hard). A participating subject is to be randomly presented with a stimulus followed by a de-scrambled version of the same stimulus (serves to remove iconic memory). The time scale of the image presentation being in that of milliseconds. Immediately following the presentation of the stimulus, the subject will be asked to input if he or she identifies the puzzle as being either solvable or unsolvable. The subject will also provide a certainty level indicating their confidence in their previous answer. Each subject will thus classify 330 puzzles.
