Objective: This study investigated the effects of motor affordances in the home environment on fine- and gross motor skills of young children aged of 18-42 months. Methodology: Homes were assessed using the Persian translation of the "Affordances in the Home Environment for Motor Development-Self-Report," while motor skill behaviour was evaluated with the "Ages and Stages Questionnaires (ASQ-3)." Findings: Results indicated that the home and its varied dimensions had a significant relationship with the status of fine- and gross motor skill behaviour. Specifically, the dimension of Inside Space was the most important predictor of gross-motor skill development, while the availability of Fine-Motor Toys was a significant predictor of fine- motor skill. In addition, SES (income, parental education) was associated with level of affordances in the home. Conclusions: These results add to the growing understanding that home motor affordances can have a significant influence on a young child's motor skills development.
