Abstract: The purpose of this study is to analyse the effects gross motor skills in preschool children between the ages of 5 and 6 have on their peer relations and social status. A relational survey method was used for this study. A total of 119 children between the ages of 5 and 6, attending a private nursery in Denizli, a province located in the Southwest of Turkey participated in the study. Results discovered that gross motor skills of preschool children have a significant predictive effect on their pro-social behaviour, aggression, asocial behaviour, exclusion, fear-anxiety, hyperactivity-distractibility, victimisation and the peer acceptance levels. The research results are striking in terms of illustrating the effects physical development in children has on the interaction between their peers.
