Abstract
42 Ss tracking manually but expecting to shift from single (manual) to double (manual and pedal) tracking later in the trial, did not track as well as they did with unifined set, expecting to continue with manual tracking all through the trial. This poorer tracking under the condition of divided set was not accompanied, however, by an reliable physiological changes (quantified EEG in 3 frequency bands, action potentials from 5 muscles, heart rate, respiration, and palmar conductance). That this absence of differences in the physiological measures was not due to their insensitivity was demonstrated in a control comparison in which highly significant physiological differences were obtained under conditions in which the performance difference very closely approximated that found in the comparison between divided and unified set. It was concluded that the performance decrement under the condition of divided set was unrelated to change in physiological activation.
