Effect of Various OR Noise on Fine Motor Skills, Cognition, and Mood

Table 1

Significant differences in tests of fine motor skills, cognition, and mood in the various noise conditions.

	OR noise vs. silence	Music vs. silence
Fine motor skills	(i) Decreased time to completion of line tracking task in both dominant () and nondominant hands ()	(i) Increased tapping speed of nondominant hand (); (ii) Decreased time to completion of aiming task in dominant () and nondominant hands (); (iii) Decreased error rate in line tracking test in dominant hand ()
Cognition	(i) Decreased immediate () and delayed recall ()	(i) Improved performance on test of complex attention, mental flexibility, and visual-motor speed ()
Mood	(i) Decreased feelings of vigor and activity ()	(i) Decreased feelings of anger and hostility (), confusion and bewilderment (), fatigue and inertia (), and tension and anxiety (); (ii) Improved total mood disturbance ()
