Prioritizing attention on a reaction time task improves postural control and reaction time.

Abstract

Flexible and appropriate allocation of attention resources is important during dual-tasking to achieve task goals while maintaining postural safety. This pilot study aimed to examine the influence of explicit prioritization of attention on the dual-task paradigm by employing two levels of difficulty for the postural tasks and reaction time (RT) tasks in healthy young adults. The task entailed standing on a force platform on two feet or on one foot, attending to posture or RT, and completing a simple or choice RT task. Participants verbally responded "top" as soon as the light cue illuminated. In general, attending to RT produced faster RTs (F(1,19) = 30.9, p < 0.001) and improved center of pressure (COP) Displacement (F(1,19) = 5.1, p < 0.05) and 95% Area Ellipse (F(1,19) = 7.1, p < 0.05). These findings suggest that prioritizing attention away from posture may be beneficial for postural performance when completing a second task.
