Parkinson's disease is a progressive neurodegenerative disorder that causes motor and non-motor symptoms. Non-motor symptoms such as mood disorders severely affect patients' quality of life. The interrelationship of multiple non-motor symptoms with each other makes comprehensive therapies necessary to simultaneously address different psychological aspects of patients. The present study was performed to compare the effectiveness of the treatment package based on psychological factors related to Parkinson's disease and memory specificity training (MEST) on the mood of these patients. The study was a quasi-experimental with a pre-test-post-test design along with a control group. 18 Parkinson's patients were eligible to participate in the study, so the selection of sample subjects was nonprobability and they were randomly assigned to three groups. Due to the possible discrepancies between the groups and to adjust it, the method of analysis of covariance was used and pre-test scores were taken. Groups were matched by gender. Data collection measures were the autobiographical memory test (AMT) and Beck's Depression Inventory- second edition (BDI-II). Data were analyzed by the covariance method and SPSS v.25 software. Data analysis showed that the mean level of depression increased in the control group, while in the package therapy and MEST groups the level of depression decreased. Data analysis showed that the mean mood scores in the post-test only in the MEST group were significantly different from the control group (P <0.05). There was no significant difference in the mean mood scores of the package therapy and control groups in the post-test; however, the mean mood scores in the two groups of package therapy and MEST were not significant. According to the research findings, MEST can be effective as a multidisciplinary intervention in improving the mood of Parkinson's patients. Supporting the effect of the treatment package based on psychological factors on mood requires further research.

Criticisms to efficient market theory and its rational assumptions as well as econometric analyses on pricing time series, DPS and incomes led to the development of models that related psychology to financial markets. Subsequently, researchers found many exceptions in financial markets and concluded that psychological phenomena play an important role in determining behavior in financial markets. In this research, different types of investors’ behavior have been analyzed in different time scales. The authors have designed a general model for capital market of Iran using the time series data of Tehran Stock Exchange companies reported from 2006 to 2010. Wavelet analysis was used as a statistical and analytical instrument to explain trait and multi resolution . Research results show that investors have different reactions after good or bad news. Their reaction in long term scale is more significant than that in short term scale. However, no significant difference was found among investors behavior in different industries.
