IRCT20171022036932N2 IRCT 2018-11-30 Iranian academic center for education culture and research The Impact of Transcranial Stimulation on Positive Emotions and Working Memory The Impact of Transcranial Direct Current Stimulation on Positive Emotions and Working Memory in Healthy People 2018-11-04 anticipated 40 Complete https://irct.ir/trial/27460 interventional Randomization: N/A, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Blinding description: Subjects are unaware of which of the two experimental or control groups are assigned. Measurement is done by one of the research colleagues who is completely unaware of the placement of the subjects. In other words, it will be done blindly. 3 working memory, positive emotion. Intervention 1: The intervention group will be assessed before the intervention using the positive and negative affect scale (PANAS) and n-back task due to computer. Measurement is accomplished by one of the research partners who are completely unaware of the placement of the subjects in the two groups of intervention and control. This test will be carried out in a laboratory environment. Variables such as temperature, light and sound are controlled in all sessions. During the test, first, the performance of the tDCS device will be explained to the subjects, and the Consent letter will be signed by the subjects with the possible side effects of the test. Subjects will be given further details on the test process. A direct electric current is received from an electric current-generator device and transmitted to a pair of electrodes. The electrodes are carbon-based and placed inside the sponge coating that has been contained with serum. The intervention group will receive an electrical stimulus from the brain. In such a way that a certain intensity will pass through his brain in 20 minutes. After a short break, the subjects will again perform the Positive and Negative affective questionnaire (PANAS) and the n-back task due to computer. Then the money will be paid as a fee and subjects will be discharged at the end. Intervention 2: Control group: The control group will be assessed before the intervention using the positive and negative affect scale (PANAS) and n-back task due to computer. Measurement is accomplished by one of the research partners who are completely unaware of the placement of the subjects in the two groups of intervention and control. This test will be carried out in a laboratory environment. Variables such as temperature, light and sound are controlled in all sessions. During the test, first, the performance of the tDCS device will be explained to the subjects, and the Consent letter will be signed by the subjects with the possible side effects of the test. Subjects will be given further details on the test process. Then, the control group receives artificial brain electric stimulation from the skull. To artificially stimulate the location of anode and cathode electrodes, it will be the actual stimulation. While the flow generator outputs the current to 2 mA for 30 seconds, then it gradually returns to zero for 30 seconds, and the device turns off. But the electrodes will be on the subject for 20 minutes, and he will not be aware of the power off. After a short break, the subjects will again perform the Positive and Negative Affective Questionnaire (PANAS) and the n-back task due to computer. Then the money will be paid as a fee and subjects will be discharged at the end. Yes - There is a plan to make this available What will be shared: The total potential data includes the scores that subjects have received from positive emotional questionnaire and working memory task after unidentifing can be shared. When: Start the access period 6 months after sharing the results To whom: Researchers working in academic and research institutes Conditions: The publication, or presentation or analysis of data should be done with the research author's permission Where to obtain: Department of Cognitive Science, Jahad Alborz University, Dara Building, Poone Street, Golshahr telephon: 02634574607 E-mail: cognitivescience.acecr@gmail.com Responsive person: Dr.Nima Gangi How to obtain: If people want to ask for documents by e-mail, they must email the email address mentioned in the previous option. A response will be sent about a week to ten days later. In case of needing a personal appointment, the contact person will be contacted first by phone and appointment will be sent to the Office of the Department of Cognitive Science. Comments:
