The aim of this research was to predict studentschr('39') academic procrastination based on metacognitive beliefs about procrastination with the mediating role of test anxiety The research method was descriptive-correlational. The statistical population included all undergraduate students of Shahid Beheshti University of Tehran in the academic year of 2019-20, from which 320 (206 females and 114 males) were selected by multi-stage cluster sampling. The Procrastination Assessment Scale for Students, Spielberger test anxiety questionnaire and Metacognitive Beliefs about Procrastination Scale were used to collect data. Data were analyzed by structural equation modeling. Findings showed that the suggested conceptual model has a good fit with the data. The variables of test anxiety and metacognitive beliefs about procrastination accounted for most of the variance in academic procrastination, respectively, and explained a total of 28% of its variance. Negative metacognitive beliefs about procrastination only indirectly affected academic procrastination through test anxiety, and full mediation was endorsed. According to the results, it can be concluded that negative beliefs about procrastination make students prone to test anxiety and academic procrastination. Therefore, modifying these beliefs can be considered as an intervention program to decrease test anxiety and academic procrastination.

Combining psychoanalysis and neurology feels peculiar at first. The combination that tries to bind concepts of psychoanalysis with neuroscience in order to provide an integrates knowledge for better understanding of human mind. However, interaction between psychoanalysis and neuroscience has come to attention during past three decades. Purpose of this study is to investigate and find correlation between three styles of defense mechanism, Mature, immature and neurotic defense mechanism with executive functions within universities students of Tehran. For this matter a study performs on a sample of 140 students (including 76 women and 64 men) by available sampling. The instruments of this research were The Defense Styles Questionnaire (DSQ40) and four computer base test for executive functions including Continues Performance Test (CPT), Strops, 1-back, Go-No Go. The data was analyzed by Pearson correlation and multiple regression method. This study demonstrated significant relation between styles of defense mechanism and executive functions and also forms a model to estimate executive function shares in neurotic and growth defense mechanisms. As a result, the findings suggest that one’s performance on executive functions can affect their style of defense mechanism.

Emotion Recognition is the main component of social cognition. The failure in emotion recognition can jeopardize the survival of the human in the environment. Emotion recognition has various pattern in different cultures and nationalities. Some of the emotions would recognize as strong or weak. Also, there is diversity in emotion recognition pattern in some psychological disorders and neurological damages. Finding the Iranian emotion recognition pattern with a valid neuro-psychological test is the main purpose of this study. This is a descriptive-analytical study. Participants with the age of 24 to 40 years were initially tested in computer intelligence and progressive matrices of Raven-2 Then, for 88 subjects who had obtained a normal score in the RAVEN-2 test, the excitement recognition subtest was taken from the Cambridge Neuro-Psychological test automated battery (CANTAB). The correct response of participants to each of the six emotions used for analysis. The average percentage of correct responses to each of the six emotions has been analysis by SPSS statistical software. The normal distribution and spherical condition exist among the accumulated data. The maximum rate of correct responses was 75.83% related to happy emotion, sad 70.00%, Surprise 68.48%, disgust 47.84%, angry 42.54%, and fear 38.26%. Iranians recognized happy emotions better than the other emotions and fear was the lees recognized emotion. The finding of this study can affect the evaluation of cognitive elements in the particular society like Iran and can identify the most cognitive abilities and inabilities in people. The result of this research deduces striking findings that can lead the evaluation of cognitive, social people of Iran.

With the significant increase in the computer and internet usage, the new concept of addiction to internet games is now considered as a new psychiatric disorder. The evidences have demonstrated that the internet gaming disorder is similar to drug addiction in terms of neurology, but just a few researches has been done in terms of brain functions. The aim of this project is to compare Inhibitory control and risky decision making among heroin and methamphetamine users, internet gaming disorders and normal people. To do so 180 men participants (45 persons in each group) were selected via simple nonrandom or convenience sampling. Subjects of the study were evaluated using go/no go and Balloon Risk Taking Task (BART) test. For analyzing the results multivariable analyze of variance was used. Results showed that inhibitory control in both substance abuse disorder and internet gaming disorder was significantly lower than normal group (P<0.001). Although internet gaming disorder group showed better performance in comparison with substance abuse disorder group. (P<0.001) Moreover, risky decision-making in internet gaming disorder group was similar to substance abuse disorder group and was significantly higher than normal group (P<0.001). Generally, there are relative similarity in impulsivity parameters particularly in risky decision-making and inhibitory control between internet gaming group and substance abuse group. This can lead to continue taking drugs or online gaming despite of their annoying consequences.

Efforts to further progress in practice and learning have introduced cognitive imagery and action observation. The aim of this study was to investigate the effect of different practice ratios on consolidation the motor memory of girls with cognitive load. This research was a quasi-experimental study with a pretest, acquisition and retention design. The statistical population of the study includes primary school students in the 18th district of Tehran in the academic year of 97-98 who were selected by convenience sampling method. 98 elementary school girl students in the age range of 8-12 years were randomly divided into 10 groups (physical practice, motor imagery, action observation, motor imagery - physical practice and action observation - physical practice) based on inclusion criteria. Were. Demographic, motion imaging (MIQ-R) and motion imaging resolution (VMIQ-2) questionnaires, Strope task and serial color matching task were used to collect information. Participants made an effort in the 1920 acquisition phase and 48 hours later in an 80-block memorial session. To analyze the data, analysis of covariance test 2 (assessment steps: acquisition, retention) × 5 (experimental groups) with repetition on the factor of assessment steps, SPSS software was used. The results of analysis of variance showed that the main effect of practice type and cognitive load type was significant (p <0.05). The results of Bonferroni post hoc test showed that the participants in the practice observation and imaging group with low cognitive load had the best performance and the participants in the practice group with low cognitive load had the weakest performance compared to the other groups. Performing practice in a combination of observation and imaging will lead to better performance in learning and consolidation motor memory.

The aim of this study was to investigate the effect of emotional induction on physiological characteristics and cognitive functions of adolescents based on psychological hardiness. In order to meet this aim, 400 students from 2 high schools in 2nd district of Tehran completed the Ahvaz Hardiness Questionnaire (AHI), of which two groups of 20 participants were selected based on the mean and standard deviation (10precent). One group included participants with a low hard score, and the other included hard participants. The pieces of films that create positive and negative emotional experiences (Mixed) were used in order to induce emotional experiences. The pieces of films (5 minute) were displayed individually for participants in each group. Physiological responses of the participants (systolic blood pressure, diastolic blood pressure, and heart rate) were measured by the digital barometer and the participants’ cognitive performance were measured in two areas of attention and memory using the WAIS(III) as cognitive function - Wechsler Adult Intelligence Scale-revised (WAIS-R) - before and after watching the films. The results of the study showed that there was a significant difference between the three baseline measurements of positive excitement induction and negative excitement induction for heart rate, systolic blood pressure or diastolic blood pressure at P <0.01. There was also a significant difference between the three baseline measurements of positive excitement induction and negative excitement induction for cognitive functions at P <0.01. Overall, the research findings indicate that people with high stubbornness have the power to prevent emotional and impulsive reactions to potentially stressful situations or events due to their hardiness and high self-control. They can effectively alleviate stressful situations and prevent mental and physical problems.
