 This study examined the mediating effect of self-balance on the structural relationship between cognitive ability and social problem solving with attention.

Research method was descriptive and correlational. Subjects were 308 participants (188 female and 114 male) selected by available sampling among aircrew of Iran Air company. To collect data, the following questionnaires were used:Nejati’s Cognitive Abilities Questionnaire, Hardin’s Integrated Self-Discrepancy Index (ISDI) and Social Problem Solving Inventory-revised short-form by D’Zurilla, and Nezu.

The results revealed that all the subscales of cognitive ability are correlated negatively with the components of adaptive problem solving and are positively related with the non-adaptive problem solving, with the significant level of 0.01. Also the four sub scales of Self-Discrepancy were related positively with adaptive problem solving and negatively with the non-adaptive problem solving and are correlated significantly on the level of 0.01.

Due to the increasing evolution and complexity of the cognitive processes of the human brain, further studies are needed to enhance the relationships among personality, problem solving and cognitive abilities. Therefore effective programs are suggested for cognitive enhancement of employees in critical jobs like aircrew. 

Explaining the effect of cognitive ability on the social problem-solving skills through Structural Equation Modelling (SEM) with the mediating role of self-balance was the overarching goal of this study. The participants of study were 308 persons (188 female and 114 male). The participants were selected using the convenience sampling technique from the aircrew of Iran Air who were tested thereafter. To collect data, the following four questionnaires were used: Hardin’s Integrated Self-Discrepancy Index (ISDI), Social Problem Solving Inventory-revised short-form by D’Zurilla, and Nezu, and Baker’s Emotional Processing Scale. The results show that all the components of emotional processing with the components of adaptive problem solving are negatively correlated with the components of non-adaptive problem solving and are positively correlated with the significance level of 0.01. Also, the quadruple components of self- balance are correlated positively and correlated positively with the components of non-adaptive problem solving components negatively and at a significant level of 0.01. The use of confirmatory factor analysis using AMOS 18.0 and Maximum Likelihood Estimation (ML) showed that the measurement model was fitted with the collected data as desirable and all the indicators of the measurement model had the power to measure the variables. The structural model like the measurement model is fitted with the collected data. According to the results of this research, Training and upgrading cognitive ability lead to improvement of the problem-solving skills of flight operations personnel.

The present research is carried out with purpose of the reviewing the predictability of job burnout by defense mechanisms used by air staff of Islamic Republic of Iran. The main hypothesis of this research is the predictability of job burn out by defense mechanisms. For answering to above hypothesis 234 subjects (137 male and 97 female) of air staff of Islamic Republic of Iran were selected by an available sampling. The device of the research is defense method questionnaire (Andrews, 1993) and Jackson and Maslach’s professional fatigue questionnaire. After collecting question-naires, analysis was done by using descriptive statics methods, Pierson’S correlation, multivariable regression analysis and independent T test about obtained data. The results of this research after analyzing the data were obtained in a way that the people with not grown defense mechanism has positive significance affect on emotional exhaustion and it was indentified that the more grown defense mechanism and neurotic defense has positive significance affect on depersonalization. This research also shows that the grown defense mechanisms and neurotic defence have positive significance affect on individual success.
