Purdue Pegboard performance of normal preschool children

Area of Science:

• Developmental Psychology
• Motor Control
• Neuroscience

Background:

• The Purdue Pegboard is a standard tool for assessing fine motor skills.
• Normative data for very young children (ages 2.5-5.11) using the Purdue Pegboard are limited.
• Understanding early motor development is crucial for identifying developmental trajectories and potential delays.

Purpose of the Study:

• To establish normative data for the Purdue Pegboard test in a cohort of young children.
• To examine developmental trends in peg placement efficiency across different conditions (right hand, left hand, bimanual).
• To assess the reliability and stability of Purdue Pegboard performance in this age group.

Main Methods:

• The study involved 206 right-handed male and female children aged 2 years, 6 months to 5 years, 11 months.
• Participants performed the Purdue Pegboard test, with scores recorded for right-hand, left-hand, and bimanual peg placements.
• Test-retest reliability was assessed to ensure performance stability.

Main Results:

• Purdue Pegboard scores demonstrated a monotonic increase with age, indicating improved peg placement efficiency.
• Developmental trends showed enhanced performance in right-hand, left-hand, and bimanual conditions as children aged.
• High test-retest reliability was observed, suggesting stable performance within this age range.
• Continuity was noted between the obtained data and normative data for older children.

Conclusions:

• The study provides valuable normative data for the Purdue Pegboard in early childhood.
• Findings highlight age-related improvements in fine motor skills and peg placement efficiency.
• The results support the use of the Purdue Pegboard for assessing motor development in young children and suggest a dissociation between hand preference and placement efficiency in younger age groups.
