In this study, the relationship of spirituality in the workplace with the occupational motivation is investigated. The research procedure is applicable and correlation in terms of purpose and descriptive research method, respectively. Requisite data are gathered by employing questionnaire tools. Statistical universe comprises the personnel of the South - West district of Khatam - al -anbia Air Defense in which 196 people are randomly chosen as samples. Spirituality in workplace questio nnaire by Mylymn et.al. and Utrecht work engagement questionnaire are used. In order to analyze the obtained data from the collected questionnaires, correlation test and simple linear regression analysis are used to examine the theorems which measure the influence of the independent variable on the dependent variable. Results demonstrate that spirituality and its dimensions having effects on occupational motivation of the Islamic Republic of Iran's army personnel.

Aim of the present research was to examine the effectiveness of Neurofeedback on cognitive flexibility. This semi experimental study was the type of pretest-posttest with control group. Therefore, 30 master students chose by the way of available sampling and asigned in two groups randomly (experimental group and control group, each with 15 members). They were assessed by Stroop test before and after the implementation of the research. Number of Neurofeedback learning sessions was 20 half an hour sessions. The experimental group was learned in 20 continuous workdays. There was no learning in control group. Data examined using covariance analysis. Results demonstrated that after 20 Neurofeedback learning sessions, there was significant improvement in cognitive flexibility. The two groups had remarkable difference from the viewpoint of cognitive flexibility. Neurofeedback is an operant conditioning of brain waves and from that way people know to control their brain waves voluntarily and therefore improve their functions including cognitive flexibility.

Aim: Cognitive functions are among important subjects of psychology. Decision making is a cognitive function that has been received too many attentions. The main aim of the research was to verify the effectiveness of Neurofeedback on risky decision making. The study was done half experimentally. Therefore, 30 students was chosen by available sampling and set randomly in two 15 person experimental and control groups. The both experimental and control groups were evaluated with Balloon Analogue Risk Task (BART) in two before and after Neurofeedback learning steps. The experimental group was learned Neurofeedback 20 sessions, while the control group received no learning. Data were analyzed using single variable covariance analysis (ANCOVA). Results demonstrated that after 20 sessions Neurofeedback learning, students of experimental group had significant improvement in risk-taking decrease. Neurofeedback is a brain waves operant conditioning in which people learn to control their brain waves voluntary and through that they can improve their functions such as decision making. Based on the results of this study, Neurofeedback is an appropriate approach to improve and reinforce the cognitive functions including decision making.

Aim: Cognitive functions are among important subjects in psychology. Memory is among cognitive functions that has been lionized. Present research has examined the effectiveness of Neurofeedback on memory reinforcement.
This study was done half experimentally that 30 healthy people was chosen by available sampling and set in two groups randomly¡ experimental group (15 member) and control group (15 member). There was no learning in control group. Neurofeedback learning for experimental group was 20 half an hour sessions. Test tasks of both experimental and control group was evaluated by Wechsler Memory Scale (WMS) in two steps¡ pretest and posttest. Data was analyzed using single variable covariance analysis.
results demonstrated that Neurofeedback learning was caused to reinforce and improve memory in experimental group in comparison with control group. There was remarkable difference from the viewpoint of memory in two groups..
Based on results of this study¡ Neurofeedback is a suitable way to improve and reinforce cognitive functions including memory.
