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.
Being between 3 and 6 years of age
For typically developing children, having no diagnosis of any neurodevelopmental or orthopedic disorder
Having a diagnosis of Pervasive Developmental Disorder made by a child psychiatrist or pediatric neurologist
Absence of visual, auditory, or motor impairments that would prevent administration of the Peabody Developmental Motor Scales-2 (PDMS-2) and the Catch Pad reaction test
In the typically developing group, having a diagnosis of Attention Deficit -Hyperactivity Disorder (ADHD) or any other neurodevelopmental disorder
Presence of additional neurological or orthopedic conditions, apart from Pervasive Developmental Disorder, that would interfere with test administration
Visual or hearing impairments severe enough to prevent test administration
History of orthopedic trauma or surgery within the last 6 months that could affect motor performance
In this study, the sample will be selected using a purposive sampling method from children aged 3-6 years who meet the predefined inclusion and exclusion criteria.
Case-control
Prospective
Peabody Developmental Motor Scales
Other interventionMotor 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.
Peabody Developmental Motor Scales
Reflexes, locomotor skills, object control, grasping, and visual-motor integration will be evaluated by this test
Simple Reaction Time Test
Reaction time will be evaluated by this test
