Abstract
The ability to direct the gaze to optimal areas in the environmental context, at the appropriate time, is central to success in all sports. The aim of this study was to changes determine the elements of QE, during the run a reactivity launcher targeting skill, under different environmental demands. That was done to identify perceptual - cognitive effects performance-based infrastructure processes. Thus, 8 Athletes (22-28 Years old) with at least 5 years’ experience in dart throwing, in a counterbalanced manner performed under four target conditions of constraints environmental. Regulatory conditions (stationary/in motion) and inter-trial variability (present/absent) created four target conditions for reaction. During the run a launcher targeting skill and was continuously recorded characteristics related to gaze behavior in each scenario. In each condition, 10 trails 20 seconds conducted. Gaze behavior using an eye-tracking device Dikablis Professional Wireless model recorded and analyzed using DLab software information processing system and variance (ANOVA) with repeated measures. Results showed that there was significant between averages QE in four different environmental contexts (P≤0.001). The fastest QE onset was observed stationary – no inter-trial variability and QE offset and QE period belonged to in motion – no inter-trial variability and in motion– inter-trial variability. In general investigating factors involved in skillful performance in different implementation conditions in response to various constraints can be facilitator and effective in identifying important factors learning motor skills.

Abstract
The purpose of this study was to examine the effect of motor dependent/independent visual perception training on visual-motor integration and fine motor skills of 7-8 year old children .For this purpose, 107, 1st grade primary school students in Sabzevar were selected through purposive sampling (with equal economical and cultural status , optimum mental and physical health and full sight with or without wearing glasses) and randomly divided into two experimental (no=32)and a control group (no=43). After attending a pre-test session, one of the experimental groups was trained in movement dependent visual-perception tasks while the other group performed movement independent visual-perception tasks. Both groups performed their tasks for three sessions, 45-minute per week and for six consecutive weeks. Shapiro-Wilk and Levin test results confirmed the normality and homogenity of data and ANCOVA showed that both training programs significantly improved visual-motor integration and fine motor skills of 7 to 8 years old children. However, Bonferroni test indicated that there were no significant differences between the movement dependent and independent training programs. The data analysis was performed by using SPSS 19.0. The results of this study confirmed the purposed "movement" hypothesis stating that the significant contributor to the development of perception and perceptual-motor components is not the active or passive movements of the individual, but rather it is the attention of the person to the visual stimuli within the environment.

Abstract
A few studies have examined the interactive self-control effect on the type of self-modeling feedback. The purpose of this study was to determine the effect of providing different strategies of self-control feedback through self-modeling on learning of Lay-up shot basketball skill. For this purpose, 60 right-handed 11-13 years old male beginner students were selected through available sampling. Then they were divided into 4 groups randomly. One of the groups between the blocks and the other group before training session defined to get the type of self-modeling feedback (best performance or overall performance in Lay-up shot basketball skill). For each of these groups, the yoked group was selected. The training program was conducted for 6 sessions for two weeks. Pretest, retention and transfer test were made in 12 attempts. Results showed significant effect between pretest with retention and transfer tests scores. Also, there was significant difference between the self-control feedback before sessions and the self-control feedback between the blocks groups and their yoked group in the retention and transfer tests (P≤001), While between the yoked groups did not had any significant difference. These results indicate the greater effect of self-control feedback during sessions, which emphasizes the greater autonomy of learners as one of the psychological needs for learning optimization.
