Abstract
The failures of memory function in post-traumatic stress disorder and its relationship with severity of symptoms need to take new approaches to improve the memory performance in patients. The aim of this study was to investigate the Effectiveness of emotional working memory Training on improvement memory in adolescents with Post- Traumatic Stress Disorder (PTSD). For this purpose, 4 adolescents (M: 2 F: 2) were selected available sampling by using 2 instruments (SCID-I) & (IES-R) The selected people– one by one were under emotional working memory training during 20 sessions. All people were assessed during three stages (pre-training, post- training and 2 month follow up) by children' Wechsler Digit Span Test (direct and reverse). Data were analyzed using the indices for trend changes, slope and the visual inspection of the charts; recovery percent index and effect size were used to determine the clinical significance. The results showed that emotional working memory training lead to increase in ability of participants in memory from pretest to follow up who suffering from Post- Traumatic Stress Disorders. Regarding the current study, it can be said that emotional working memory training is an appropriate choice for increase in memory in adolescents suffering from Post- Traumatic Stress Disorder

Abstract
The main purpose of this study was to determine the effect of computer cognitive empowerment on the attentional functions, concentration and cognitive effort of the elderly. Metods This study was a quasi-experimental study with a pretest-posttest design with a control group. Participants were 30 elderly people who were selected by convenience sampling method and randomly assigned to the experimental and control groups (Each group includes 15 people). Instruments included Captain's Log cognitive software and D2 test. Data analysis was performed using analysis of covariance. Data analysis using analysis of covariance showed that there was a significant difference between the mean scores of pre-test and post-test in the experimental and control groups (p <0.001). The results of this study show that computer cognitive empowerment can be used as an effective method to improve attention, concentration and cognitive effort in the elderly.

Abstract
Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders and efforts to improve its diagnostic methods continue. In this study, using CogLab software, a diagnostic model was developed and introduced to help psychologists as an auxiliary tool for diagnosing ADHD. In the context of a developmental and case-control project using targeted sampling in Rasht city, 93 children diagnosed with ADHD were selected by a pediatric psychiatry subspecialist. The parents of both groups (case and control) were also interviewed clinically and after completing the CSI-4 version of the Children's Disease Symptoms Questionnaire, their demographic information was collected. The control group consisted of 33 working students from Rasht schools without disorders were selected using the CSI-4 4th version of the Children's Disease Symptoms Questionnaire. Both groups responded to the change detection and spatial marking tests using the attention section of the CogLab software under the same conditions. Data were processed by SPSS-24. In the diagnosis analysis, the results showed that the ratio of the correct response to the detection of change in the so-so mode had the highest predictive power in the separation and differentiation of classes between the case and control groups, and the results of the diagnostic function in the cross-validation section were able to be found in both case and control groups. 80.6 percent of all people in the ADHD group (case) and also 72.7 percent of all people in the control group were correctly grouped; The change detection test and spatial marking in CogLab software platform can be used as an auxiliary tool in the service of psychologists to help the diagnosis process in children with ADHD.

Abstract
The purpose of this study was to compare the effectiveness of transcranial direct current stimulation (tDCS) and short-term cognitive rehabilitation protocol on Symptoms of hallucinations and delusions in the elderly with mild Alzheimer's disease. The research method was an extended experiment with two experimental groups and one control group, which was conducted using the pre-test and post-test method. The statistical population included all elderly people over 65 years of age with mild Alzheimer's who had referred to a neurologist in 1401, and among these people, 60 people were selected by available sampling and then randomly. They were assigned in two experimental groups and one control group (20 people in each group). Then, the independent variables of transcranial direct current stimulation (tDCS) for 10 sessions of 20 minutes once a week on an experimental group and a short-term cognitive rehabilitation program for 9 sessions (90 minutes each session) It was designed according to the documentary method and based on Luria's (1963) healthy function replacement approach, and after confirming the validity of the content by experts, it was applied to the second experimental group once a week, and no intervention was performed on the third group. After the end of the intervention, the post-test was conducted with an interval of one week on the experimental and control groups. After one month, the studied groups were followed up again. Neuropsychological Questionnaire (NPI) was used to collect data. The results showed that both methods improve hallucination symptoms in the elderly with mild Alzheimer's and there is no significant difference between the effectiveness of these two methods. while they had no significant effect on the delusion variable. Therefore, it can be concluded that both methods can be used to improve hallucinations in the elderly with mild Alzheimer's disease.
