Abstract
The aim of this study was to investigate the effect of metacognitive strategies and observation of skilled model on learning of soccer chip task. The present study was carried out by means of semi-experimental research design. Forty two students, aged 11-13 years old, in region 2th of Tehran, participated in this study. They were divided in 3 groups (control group, observation of skilled model, and observation of skilled model with metacognitive activities). Metacognition group had to complete a semi-structured written interview that prompting them to activate their high-order thinking, before and then of acquisition blocks. An experimental intervention study in of soccer chip shot was conducted with pre-, post-, retention and transfer tests. Repeated measures analysis showed that there were statistically significant differences between groups. The result revealed that metacognitive strategies prompting had significant influence on students’ performance.

Abstract
In this study we manipulate structure of combined practice (physical along with self-modeling of positive self-review) to examine its effects on motor memory reconsolidation process and motor transfer in children. 36 female students (9-12 years old) from Maktabi elementary school of Qom trained Dart throwing. Of the 15 trials (from 1.5, 2, and 2.5 meters in blocked order), Positive self-reviewing videos were provided in the pre-test. A week later, subjects practiced in 3 groups of combined constant, random and blocked practice. Paired samples T test of Means radial error between end of acquisition and tests showed significant improvement in all practice groups (P≤0.05) for 24 hour blocked retention test (after recall), significant improvement in only combined blocked practice group (P=0.016) for 24 hour constant retention test (after recall) and significant decrease in all practice groups for 24 hour transfer test (after recall). Therefore re-stabilizing motor memory during reconsolidation could occur in children and low variable (blocked) practice could lead to more improvements in reconsolidation process and transfer of motor memory in children.

Abstract
In this research connectionist modeling of decision making has been presented. Important areas for decision making in the brain are thalamus, prefrontal cortex and Amygdala. Connectionist modeling with 3 parts representative for these 3 areas is made based the result of Iowa Gambling Task. In many researches Iowa Gambling Task is used to study emotional decision making. In these kind of decision making the role of Amygdala is so important and we expect that a model with two parts (thalamus and Amygdala) can have the best result in modeling participants decisions without considering any part for cortex process. For this purpose 56 participants composed of 20 men and 36 women wanted to do Iowa Gambling Task. Results show that the networks related to two parts model predict 62.57 Percent’s of participant’s decisions and the 3parts model has 68.46 Percent’s of that. In conclusion it can be said that three parts modeling has been more success than mathematical two parts model in predicting the performance of participants and the difference is significant. In other words cortex role in this kind of decision making is quite important.
