Abstract
The purpose of this study was to determine the effects of goal setting on declarative memory performance in tasks with different cognitive loads. 60 female students were selected randomly and divided into short-term goals, long-term goals with high and low cognitive loads and the control groups. For this purpose, the Petersburg sleep quality questionnaire, Goldberg mental health questionnaire, inventory cognitive function, Annette handedness questionnaire, and Stroop software (task with high cognitive load) and color matching chain (task with low cognitive load) were used. All groups practiced four training sessions in four days based on type of goal setting instructions. The retention test was performed 24 hours after the acquisition phase. Data were analyzed using the factorial repeated measures ANOVA (acquisition phase), two-way analysis of variance, one way analysis of variance and Bonferroni post hoc test (retention test). Results showed significant differences among experimental groups in the acquisition phase (P<0.05). The short term goals group performed better than the other groups in the retention test and task with high cognitive load (stroop task). Also, the short term goals group had better performance than control group in the low cognitive load task (color matching task chain). Furthermore, comparing the groups in tasks with high and low cognitive loads in the retention test showed that the short and long term goals groups in task with high cognitive load performed better than the short and long term goals groups in task with low cognitive load. Thus, the results indicate that goal setting instructions are more effective in task with high cognitive load.

Abstract
The purpose of this study was to investigate the effect of combined cognitive rehabilitation interventions (computer and manual) on improving the speed of information processing and improving the mental status variables (MMSE) in women with MS. This research was conducted with pre-test and post-test design with two month follow-up. Twenty two women with MS were selected by available sampling method and randomly assigned to two groups of 12, and the experimental group received cognitive rehabilitation training and the intervention group did not receive any intervention. All participants of the first and last sessions were evaluated by MMSE and Auditory Sequence Test (PASAT). The research was conducted in 21 sessions in Arak and data were analyzed by multivariate analysis of variance analysis with repeated measurements using SPSS-24 software.The findings showed that the main effect of the time factor (pre-test, post-test, follow-up) on the selected score was significant. Conclusion: Manual cognitive rehabilitation is effective in improving the selective attention of female patients with multiple sclerosis. It is recommended that these interventions be used to improve the information processing speed and the psychological state of women with MS.

Abstract
The aim of the present study was to investigate Children's Working Memory Measurement Model: Testing Theories’ Hich and Baddeley, Baddeley and Cowan. The research design was correlational. The population included all primary school students in Tehran in 1400. Participants were 150 students aged 7 to 10 years who were selected by convenience sampling method. They all responded to the Comprehensive Memory Working Assessment Gray et al. (2017). Data were analyzed by factor analysis. The results of factor analysis showed that the Baddeley four-factor model has a better fit than the Baddeley and Hich three-factor model and Cown three-factor model. Assessing working memory can provide more important information about children's cognitive function than psychological measures.

Abstract
The purpose of this research is to investigate the effect of attention control on mind wandering. The method of this research was semi-experimental. The statistical population includes fifth and sixth grade female students of Semnan city in the academic year of 1400-1401. The number of 38 people from the statistical population was calculated as available, and in order to predict the drop of the subjects or the loss of data, 2 people were present in the study more than the number of the calculated sample. The tool used to measure mind wandering was the Stroop test, which was completed under active and reactive attention control conditions. The data were analyzed using one-factor analysis of variance and repeated measurement by SPSS25 software. The findings showed that mind wandering is more in active attention control conditions than in reactive attention control conditions. The findings of this study can provide useful insight in understanding the phenomenon of mind wandering. Teachers and educational designers, having the knowledge related to this field, can design and produce educational content that students will experience during virtual education, where the minimum supervision by the teacher takes place during the learning process. The wandering of the mind will be less on the part of the students.
