      <subfield code="3">The literature on combined manual-decision tasks is reviewed and the data reanalysed. It is shown that in all cases where the tasks are done sequentially, the total time for the task is the sum of the times for the decision and movement components. New experiments are reported in which subjects concurrently carried out the two components of the task; the decisions were made while the movement was being perfomed. Under these circumstances, there was  considerable interference between the decision (hick's law) and movement components (fitts'law) so that the time for the task was increased. The amount of interference was dependent on the difficulty of each component of the task</subfield>
