About this study
Official title: The Relationship Between Reaction Time and Motor Skills in Preschool Children With Pervasive Developmental Disorders
This study examines whether the relationship between reaction time and motor skills differs between children aged 3-6 with pervasive developmental disorders and typically developing peers. It aims to determine the direction and strength of this relationship in children with developmental disorders and compare it with that of typically developing children, thereby providing evidence on how cognitive processing speed and motor performance interact in early childhood under developmental disorder conditions.
Read the detailed description
This study is designed as a descriptive and comparative investigation aimed at examining differences in motor skills and reaction times between children aged 3-6 diagnosed with pervasive developmental disorders and their typically developing peers. The sample consists of 15 children with pervasive developmental disorders attending special education and rehabilitation centers and 15 typically developing children from the same age group.
No training or intervention program will be implemented; data will be collected through single-session, one-time assessments. To comprehensively evaluate motor skills, the Peabody Developmental Motor Scales-Second Edition (PDMS-2), widely regarded as a gold standard in child development assessment, will be used. In addition, participants' reaction times will be measured using the reaction test module of the Catch Pad application, a digital tool frequently utilized in scientific research.In this way, performance components including both general motor skills and response speed will be objectively measured, and differences between the two groups will be scientifically identified.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Peabody Developmental Motor ScalesOther
Motor skills will be assessed using the Peabody Developmental Motor Scales-Second Edition (PDMS-2), a standardized and validated tool measuring gross and fine motor performance. Subtests will be administered face-to-face in an age-appropriate manner and scored according to the manual.
