Neurocognitive Assessment Tool (NCAT)
NCAT CollectPurpose: NCAT Collect was designed to measure a range of factors that contribute to or influence children’s processing of information. It measures brain activity, executive functions, sleep patterns, behaviour, and other factors.
Programming Language: Unity EEG input: Neurosky Mindwave II Designer: Stuart Johnstone Developer: Philip Roxas |

NCAT ReportPurpose: NCAT Report was designed to quantify measures from NCAT Collect, and to allow comparisons to the database, and generate comparative reports. The Single Channel Processing Tool allows EEG analysis for input into NCAT Report.
