Levels of postural challenge and instructions of task prioritization were manipulated to obtain this goal. Results indicated that fall-fearful subjects demonstrated a reorganization of attentional resources when challenge to upright standing was imposed.

However both fall-fearful and non-fearful subjects demonstrated flexibility in the prioritization of the postural task.
