US Patent 9571877 Systems and methods to determine media effectiveness

Example systems, methods and machine readable media are disclosed. An example system includes a synchronizer to determine a total amount to offset first-neuro-response data gathered from a subject exposed to media to align the first neuro-response data with second neuro-response data simultaneously gathered from the subject. The first neuro-response data is associated with a first sensory component of the media and the second neuro-response data is associated with a second sensory component of the media. The total amount to offset is based on a first cognitive delay associated with the first neuro-response data and a second cognitive delay associated with the second neuro-response data. The synchronizer is to time shift at least one of the first neuro-response data or the second neuro-response based on the total amount to form aligned data. The example system includes an analyzer to determine an effectiveness of the media based on the aligned data.
