| + | the Cogstate variables are, just as all other data, presented 'as-is'. Meaning that all available data will be present. The Cogstate research group has a completion criteria for all participants. This criteria determines when according to their standards the test was valid. If a participant scored to low on one of the following variables the results of the test is considered invalid. | ||
