Investigating the relationship between cognitive emotion regulation (CER) with cognitive performance through physiological indices and determining the appropriate characteristics of predictive stimulus of cognitive performance
determine the relationship between cognitive emotion regulation (CER) with cognitive performance and physiological indices
Design
a parallel pseudo randomized trial group design of 40 control room operators in Combined Cycle Power Plant. Based on the results of the CERQ questionnaire, individuals divided into appropriate and inappropriate groups and then each group, divided into control and intervention groups.
Settings and conduct
This research will conducted on control room operators of Combined Cycle Power Plant. First the CERQ will be administered and based on the results people will be divided into appropriate an inappropriate groups in terms of cognitive emotion regulation ability. Then they will be invited to attend the DANA Brain Health Institute. Intervention group will encounter emotional stimuli and their physiological signals will be recorded simultaneously. Then their cognitive performance will be examined using CANTAB (Cambridge Neuropsychological Test Automated Battery) cognitive test. Control group will not experience any emotional stimuli and just their cognitive performance will be assessed.
Participants/Inclusion and exclusion criteria
Fars Combined Cycle Power Plant Control Room Staff, Being at least 24 years old, Having at least 4 years of work experience, No history of neurosurgery, No history of mental illness and related medications.
Intervention groups
intervention group: watch stimuli from emotional image bank (IAPS: International Affective Picture System)
control group: no stimuli
An emotional image bank known as IAPS was used for the intervention. This set includes heartbreaking and calming images, etc.
Main outcome variables
Cognitive performance (CANTAB), Physiological indices (Heart Rate, Respiration, Electromyography), Emotional stimulus profile predicts optimal cognitive performance (based on emotional coordinates)

Other design features
This research will be done in two phases. In the first phase, using the CER questionnaire, the state of cognitive regulation of emotion in the study group will be examined and individuals will be divided into two groups: appropriate and inappropriate from this perspective(people in the appropriate group use positive strategies to cognitively regulate their emotions in upsetting situations). Then, people in each group will form two subgroups (intervention and control) with the same number of members. Members of the intervention subgroup of both groups (appropriate and inappropriate) will experience visual emotional stimuli (IAPS: International Affective Picture System) and will complete the SAM questionnaire, then they will be be asked to take standardized cognitive function tests. It should be noted that physiological indicators are also recorded simultaneously. For members of the control subgroup in both groups (appropriate and inappropriate), the above steps will be performed, with this difference that emotional stimuli will not be displayed for the control group. In the second phase, the results of the first stage will be used to define the specifications of the capacity and excitability of the emotional stimulus that has led to the optimal performance, and based on that, and using related databases, the stimulus with the level of arousal and valence will be available. Then, taking into account the stimulus obtained as an intervention, the steps of measuring the physiological index and the performance measurement test will be performed.

Description
Intervention group: IAPS. According to this concept that emotion has two main components of arousal and valence, it is necessary to determine these two components in emotion-oriented research. For this purpose, a standard and global database is used, which includes a set of images that arousal and valence of them has been determined. This bank is called International Affective Picture System (IAPS). This emotional image pack contains 10 loaded block and 11 neutral block (neutral blocks will present between loaded blocks) and each block contains 13 images. Each image presents for 5 seconds.
