Systems and methods for evaluating neurobehavioural performance from reaction time tests
First Claim
1. A method for using a processor to evaluate reaction time data obtained from a stimulus-response testing system, the method comprising:
- obtaining, by a processor, reaction time data, the reaction time data comprising a plurality of reaction times, each reaction time comprising an estimate of a time required for a subject to respond to a corresponding stimulus event;
assigning, by the processor, a weight to each reaction time in the reaction time data in accordance with a weighting function, the weighting function comprising a rule that defines a mapping between reaction times and corresponding weights, wherein the weight assigned to each reaction time is based at least in part on a property of the reaction time; and
determining, by the processor, a weighted reaction time metric based at least in part on a sum of the weights assigned to the reaction times in the reaction time data, the weighted reaction time metric being indicative of a neurobehavioral characteristic of the subject;
wherein determining the weighted reaction time metric comprises normalizing the sum by dividing the sum by a total number of reaction times within the reaction time data.
