The Effect of motivation on shoulder-muscle tension in attention demanding tasks / M. Waersted, R.A. Bjorklund, and R.H. Westgaard
Sumario: This paper evaluates motivation as a task-related factor causing the development of psychologically mediated shoulder-muscle tension. In four separate experiments using a visual display unit based complex reactiontime task, motivation was established by means of continuous feedback on the level of performance or by means of a money reward for good performance. In all experiments motivation improved the performance, but an increase in the psychogenic shoulder-muscle tension was only observed in the money-reward condition
