Human performance generally suffers if two (or more) tasks have to be done simultaneously. This even applies to very simple tasks such as deciding whether a tone was high or low in pitch, and exceptions have rarely if ever been reported. Using a special paradigm, the psychological refractory period (PRP) paradigm, we have for example investigated the dual-task behavior of various grasping movements (that have been suspected to be an exception from dual-task interference). Currently, we pursue a line of research including reflexes in dual-task research with the further goal of developing a systematization of human behavior regarding their susceptibility to dual-task interference.
