Improvement of Secondary Task (Discrimination Reaction Time), Due to Motivational Self-Talk

The self-talk is one of psychological interventions that can be effective on improving and success in the motor performance and sport performance. So, the aim of the present study was to investigation effectiveness the motivational self-talkon secondary task performance (discrimination reaction time). 30 subjects have participated of the 160 students studying at the undergraduate from faculty of physical education and sport science in University of Tehran. They were divided randomly into two control and experimental groups. The intervention was conducted in two sessions per day and each session lasted one minute. The first primary task for the intervention group was walking on the treadmill with a slow speed whereas secondary task (discrimination reaction time), was performed in 10 attempts. The process was performed for the second order in the same manner with the difference that the experimental group performed motivational self-talk 15 seconds before the secondary task performance.Control group was performed test without intervention.The result of paired samples t-test showed that motivational self-talk in experimental group leads to a significant decrement in discrimination reaction time (P=0.001). Also, the result of Mann-Whitney U showed that reaction time in the experimental group decrease than control group significantly (P=0.002).
