| Sumario: | The dual-task paradigm methodology is a widely accepted approach to facilitate relative human performance measurement in a variety of tasks. The present paper describes the development and experimental validation of a visual-psychomotor secondary task. This task is proposed as a standardised secondary task set to facilitate human performance measurement during the objective evaluation of alternate primary tasks. The development of the secondary task is aligned with attributes suggested within the existing literature. The methodology is offered as a systematically derived secondary task with a tuned difficulty level which is intended to avoid floor or ceiling effects. Also, the data presented here afford the reader the ability to manipulate difficulty with known effect, if desired. Future plans include use of the secondary task set to facilitate a comparison of primary task independent variables. This activity will act to further exercise the potential utility of this 'standardised' secondary task and its associated mechanisation. |
