Attention deficit/hyperactivity disorder is a neurodevelopmental disorder that affects 3-7% of children.

The aim of this study was to compare the effect of deductive-social feedback and attention instructions on the performance of targeting skills in children with attention deficit/ hyperactivity disorder.

This research is a semi-experimental type. Its statistical population was formed by male students suffering from attention/ hyperactivity disorder in Isfahan city with an age range of 7-10 years in 2020. 48 right-handed students were randomly selected as a statistical sample based on the results of the Connors children's behavior rating scale and randomly divided into four groups of 12 people. In order to collect data Personal Information Questionnaire, Edinburgh Handedness Inventory, Ulrich's Gross Motor Development Test, Anderson's Over Shoulder Throw Scale (1999) and Luciana et al. (2012) Over Shoulder Throw Targeting Task were used. Data were analysis with using one-way ANOVA test and Bonferroni's post-hoc test using SPSS-18 software.

The results showed that the studied groups had significant differences in the qualitative and quantitative development of hand targeting skills (P<0.05). The results of Bonferroni post hoc test showed that the positive analogical-social feedback group had better and significant external attention than the other groups (P<0.05), the other groups did not differ significantly in the retention stage (P>0.05).

The results showed that the comparative-social positive-external attention group performed better, so it is suggested to use this method in teaching and learning goal-setting skills.

As the security of holding volleyball matches is very important, the purpose of this study was to design a model for enhancement of the security of Iranian volleyball halls.

The present study was a descriptive-exploratory study that 115 people from Iranian volleyball halls managers and authorities, heads and experts of volleyball associations of provinces, as well as university professors who were expert in the field of sport events and facility, and violence and aggression, responded modified stadium security questionnaire (Faraji, 2014). The collected data were analyzed using exploratory and confirmatory factor analysis.

The results showed that the Iranian volleyball halls’ security stand on around four principal areas including match planning and management, physical protection of stadium, infrastructure and personnel respectively with 0.94, 0.84, 0.84 and 0.83 factor loadings. Also, the technology has the most factor loading (0.89) for the infrastructure, the toxic and chemical control of stadium has the most factor loading (0.91) for the physical protection, training and practice has the most factor loading (0.85) for personnel and staff, and finally, the risk and crisis management has the most factor loading (0.87) for match management and planning.

According to the results, the development of security in Iran's volleyball halls depends on proper management and planning. For this reason, paying attention to the operational concepts of risk and crisis management, communication and interactions management, quality of match day services and cultural activities are necessary requirements in the field of security of Iranian volleyball halls.
