Abstract
A mass communication assessment system (2) communicating a cognitive task to selected remote test sites (12) via a network (10) for providing a two-way communication between the central control site and the remote sites, detecting brain response signals from the subject (40) to the task, and having processing means (16) for computing variations in the brain activity for the subjects at each of the selected sites.
Claims15
A method of mass assessment of psychological response in a cognitive task for a customer including the steps of:
- obtaining input data representing a cognitive task from a customer;
- transmitting input data signals representing the cognitive task from a central control site to a plurality of selected test sites remote from the test site over a network;
- presenting control signals simultaneously with the cognitive task to subjects at each or at least some of the selected test sites;
- detecting brain response signals from the subjects at the selected test sites to said control signals and said cognitive task;
- transmitting brain response signals to the central control site over said network;
- computing variations in brain activity of said subjects by calculating amplitude and/or phase and/or coherence of steady state visually evoked potentials (SSVEP) from said brain response signals for each selected site;
- and
- computing output data for the customer representing said variations in brain activity to different parts of said cognitive task.
