Aim: Thinking as one of the cognitive functions has always been of interest to researchers. With a distinction between divergent and convergent cognitive processes, Guilford has made a huge impact on experimental research on creative thinking. Alpha frequency band in the range of 12-8 Hz is associated with cognitive functions such as creativity. The purpose of this study was to investigate the increase and decrease of alpha power changes (event-related synchronization and de-synchronization) in two different types of divergent and convergent thinking. Method: The sample of this study consists of 38 postgraduate students of Ferdowsi University of Mashhad (19 males, 19 females) who were selected by available and voluntary sampling method. The brain waves were recorded using a 19-channel instrument while performing divergent and convergent thinking tasks, and alpha power changes were analyzed using MATLAB software. Results: activity of alpha waves is in the position of divergent thinking from the anterior regions to the posterior regions with synchronization, while in the convergent thinking position we have seen the reduction in the power of the alpha band in the posterior regions compared to the anterior regions of the brain. Conclusion: The activity of alpha waves is significantly associated with divergent thinking tasks, which increased activity in the posterior regions of the brain with increased activity, in contrast to tasks related to convergent thinking, indicated decreased activity from the anterior regions to the posterior regions.

Aim: The purpose of the present study was to comprison the effectiveness of the compensatory and remediatory cognitive training aiming at enhancement of the executive functions in normal adolescents. Method: The design of this study was a Quasi-experimental design with pretest-posttest and control group. The sample of this study was 31 students between 14 to 15 year old high school students who were studying at the 10th grade in (2018) in Tehran. Students were selected and randomly assigned into three groups (10 students in compensation and control person group and 11 person in remediation group). The first training group received a compensatory training for 6 weeks in 10 sessions and remediation training group performed 6 weeks training at the same time. Persian Paper and Pencil Cognitive Assessment Package (PCAP) was used to collect data. Findings: The results of analysis of Covariance (ANCOVA) showed that the two experimental groups had significant changes compared with the control group. Also, the two interventions of compensation and remediation showed significant differences in comparison with each other. That is, the compensation method has been more effective in promoting/ enhancement the executive functions (e.g. working memory, flexibility, & inhibitory control). Conclusion: The findings of the current study have been presented to improve the level of cognitive functions needed by adolescents.

Aim: The aim of this study was to investigate the interactive effect of working memory and task duration on time perception. Methods: The research method was quasi-experimental. The population of this research was school students, university students and personnel of organizations of Kerman city in 2018 and among them, 300 persons were selected by available sampling method. The time reproduction task of Shahabifar and Movahedinia (2016) was used for obtaining data. Data were analyzed by paired samples t-test and two factor analysis of variance with repeated measures. Findings: The results showed that the main effect of working memory and task duration and interactive effect of these variables on time perception was significant (p<0.01). Working memory and increase of the task duration affect time perception respectively in the form of decreasing and increasing the amount of time reproduction error. Conclusion: Time perception decays significantly with increasing length of time intervals and working memory load.

Aim: Emotional effects on human time perception are generally attributed to arousal and valence of stimuli. Recent evidence suggests that perception of emotional facial expression induces temporal distortions. Based on the internal clock model, it is assumed that emotional arousal speeds up or slows down the pace maker, while valence influences the attentional processes of the switch element. The aim of our study was to investigate the contribution of each dimension and disentangle their role in facial emotion time distortion. Method: 20 female students performed a temporal bisection task using emotional facial expressions as stimuli which were selected based on PAD model. Findings: Behavioral results revealed that high arousal pleasant stimuli (happy faces) resulted in significantly smaller bisection point, while there was no significant difference between bisection points of angry and neutral faces. The results of study were interpreted in light of SET theory and dual-stages processing of attention. Conclusion:Different Aspects of Facial Emotional affect on the Perception of Time

Background: In December 2019, a pandemic broke out in Wuhan, China, which attracted worldwide attention and was named covid-19. the World Health Organization (WHO) has announced the outbreak of the virus in a public health emergency. The most common symptoms include fever, fatigue, and a dry cough, but it has recently been confirmed that neurological and cognitive symptoms such as headache, cognitive impairment, and paresthesia are also present. Method: In this review, all articles published until May 4 , 2020 in English on the subject of covid-19 disease and its neurological and cognitive effects were examined. This search was performed through the reputable scientific databases BioRxiv, Google scholar, Scopus, PubMed and using the keywords Coronaviruses infection, COVID-19, Nervous system and the necessary information was extracted. Conclusion: In this study, reports of viral attacks on the central nervous system and the development of viral inflammation of the brain were also highlighted, and the mediating role of the immune system in fighting infection was emphasized. Lack of sense of smell and taste in infected people and its relationship with the nervous system are other important signs of the virus and are one of the first signs of an attack on the nervous system. Acute cerebrovascular disease and the process of its formation due to hypoxia and other complications of infection were also described. Therefore, it is necessary to consider the appearance of neurological symptoms in the initial evaluations, because some patients only refer to these symptoms.
