Introduction: Insomnia is a major public concern and the most common sleep problem, the treatment of which has a special place in promoting well-being and performance. One of the new therapies in sleep interventions is direct transcranial movement. The present study was conducted to determine the effectiveness of transcranial direct movement on resilience, selective attention, concentration and effort in patients with insomnia. Method: The research design was quasi-experimental with a control group with pre-test and post-test. The statistical population included all students of Semnan University in the academic year 2009-2010 with a diagnosis of insomnia. 20 people were purposefully selected as a sample and were divided into two groups of control and experiment with random assignment. The transcranial direct motion device is used for intervention and Pittsburgh Sleep Quality Questionnaire, Connor & Davidson Resilience and D2 test for measurements. The experimental group underwent intervention for 10 minutes for 10 minutes with a voltage of 1 mA and the control group underwent sham intervention. Results: The results of analysis of covariance show direct transcranial motion increase resilience, attention and focus and search, as well as improve insomnia. Conclusion: The research findings indicated that the direct movement of strategic transnationals in increasing resilience, selective attention, search and improving the level of sleep quality and can be used as a way to productivity.

Introduction: Thus, this study was aimed to investigate the first stimulus simplification and significant interference on the second reaction time. Dual stimulus task is an appropriate way to investigate humans’ limited capacity of information processing. Methods: The participants included 17 male students of Shahid Chamran University whose age average was 23.45±1.54. All of them performed a dual task test within four intervals of 50, 100, 300, 900 ms between asynchronous onset of two stimuli under congruent and incongruent and neutral conditions. Findings: The results of ANOVA with repeated measure at the significance level of P˃0.05 indicated that simplification of the first congruent stimulus, compared to incongruent and neutral stimuli; reduces the reaction time for second congruent and neutral stimuli. The required change of attention processes in dual task with second incongruent stimulus causes on significant effect of first congruent and neutral stimulus precedence over second incongruent stimulus. Conclusion: The findings suggest that simultaneous performance of dual tasks with high information processing capacity or divided attention among non-automatized tasks should be avoided. Moreover, for intial of simplification processes and significant interference at leat 100 ms be required.
