The aim of this study was to evaluate the effectiveness of cognitive rehabilitation on improving working memory of adolescents with traumatic brain injury. The method of this research was quasi-experimental pre-test-post-test with control and follow-up groups. To conduct this study, 20 adolescents aged 9-18 years with traumatic brain injury referred to medical centers in Sadaf Shahriar (Parandmehr Clinic) were selected by convenience sampling and randomly assigned to two groups of 10 experimental and control. To measure the dependent variable of working memory, Wechsler scale 4 subtests (auditory measurement of working memory) and Benton test (visual-spatial measurement of working memory) were used. The experimental group underwent cognitive rehabilitation intervention (12 sessions of 45 minutes). Analysis of variance with repeated measures was used to analyze the data. The results showed that there was a significant difference between the experimental and control groups in pre-test, post-test and follow-up of working memory performance. The results showed a significant difference between the mean scores of working memory (auditory and visual-spatial measurements) of the experimental group and the control group in the post-test. In addition, there was no significant difference between post-test scores and follow-up in the experimental group, which showed the effect of cognitive rehabilitative perstability on working memory performance in adolescents with brain injury. Therefore, cognitive rehabilitation has a significant effect on improving working memory performance in patients with brain injury and can be used as an effective and useful method to improve working memory performance in adolescents with brain damage.

The three principles of double effect, personal contact, and action are suggested as the chief psychological mechanisms affecting human moral decision making in trolley dilemmas. The purpose of current research was to investigate the claim of the universality of these principles and their role in moral decision making in trolley dilemma in the oriental culture of Iran. In this research, using a semi-experimental single group pre-test-post-test design, four scenarios were used adopted from similar research. The statistical population of this research was the general population active in social media. The sample consisted of 235 participants with an average age of 30.34. Among the subjects, 143 were women and 92 were men. "McNemar" test was used for statistical analysis. Based on the results, the effect of all three principles on the ethical decision making of the subjects in trolley dilemma was confirmed significantly (Pvalue>0.05). Therefore, this research shows that all three principles of personal contact, action, and double effect are effectively influencing moral decision making.
