Additive factors methodology was applied to dual task data to discover the pool of resources demanded when tracking bandwidth is increased. Ten subjects tracked signals of both low and high bandwidth and performed a cognitive loading task that was constructed to demand either central processing or response execution resources. The hypothesis that bandwidth increases demand response execution resources was not supported. Experimental methodology and control are discussed as possible reasons for the failure.
