Abstract
The researcher's test consists of nineteen factors and has two parts: audio and visual; its content validity was confirmed by psychology professors and then a sample of 206 pre-school students was performedAccording to the calculations, Pearson correlation coefficient between the two-part questionnaire was r = 0.81 in the auditory comprehension section and r = 0.79 in the visual comprehension section.. In order to determine the validity of the structure and the components of the questionnaire, the main components analysis method was used with varimax normalized rotation. The most important factor in the visual-spatial perception area is the symbolization, and in the auditory part it is memory. Independent t-test was used to assess discriminant validity. Results showed that there is a significant difference between the mean scores of students with learning disabilities and normal in the learning disability test. In order to check the validity of this study, a checklist of learning disability that was completed at the same time by the mothers was used. The results showed that there is a significant relationship between the two tests. According to the validity and reliability, the learning disability test is a tool that can be used by learning and counseling centers.

Abstract
One great ability of the brain is memory. Poor visual-auditory memory leads to dyslexia, dyscalculia and hyperactivity. Therefore, it is necessary to develop a test to determine the ability and accurate performance of memory. With this in mind, a test has been prepared using theoretical literature. This researcher-made memory test consists of four parts (numerical-verbal memory, visual memory, working memory and auditory-sentence memory) and its validity has been confirmed by professors of cognitive psychology and counselling in addition to using the random cluster sampling method on a sample of 308 elementary school students. The questions were analysed by relevant statistical methods and their validity, reliability and norm scores were determined. To evaluate the reliability of the test, three methods were used. The reliability coefficient was 0.83 using the internal consistency method and the Pearson correlation coefficient was determined to be r = 0.79 between the two halves of the questionnaire, which indicated that there was a high correlation between the two halves of the questionnaire. To determine the validity of the structure and components of the questionnaire, the principal component analysis method was used by rotation in the normalised Varimax method and to evaluate differential validity, an independent t-test was used. The results showed that there was a significant difference between the mean scores of male and female students. (P < 0.001 and t (204) = 2.76). Based on the obtained reliability and validity, the audiovisual memory test is a tool that could be used by disorder and counselling centres. Moreover, it could be used as a tool for early assessment and diagnosis in the case of preschool students.

Abstract
The research was conducted with the aim of determining the relationship between thinking styles and decision-making styles with the mediation of problem solving among startup employees. The research was descriptive and correlational. The statistical population of the research included all employees in the field of startups in Tehran in 1401. 300 people were selected by available sampling method and responded to research tools including questionnaires of thinking style (Sternberg, 1994), decision making style (Scott and Bruce, 1995) and problem-solving skills (Heppner, 1988). Analysis of research data using descriptive statistics methods (prevalence, percentage, mean and standard deviation), Pearson correlation coefficient, multivariate regression and structural equation modeling and path analysis statistical method with SPSS-26 software and Amos is done. Based on the findings, the proposed model had a good fit in structural equations and causal relationships between the mentioned variables. In general, in the proposed model of the research, it was found that the decision-making style is related to the thinking style both directly and indirectly through the problem-solving skills of the startup employees (P<0.05). The results showed that there was a positive and significant relationship between problem solving skills and its dimensions with decision-making style (P<0.05) and between thinking style and its dimensions with decision-making style. The collected data are consistent with the desired structural model and have a good fit. Therefore, the relationship between thinking styles and decision-making styles is confirmed with the mediation of problem-solving skills in startup employees.
