Developmental progression of clock face drawing in children.

Area of Science:

• Neuropsychology
• Child Development
• Developmental Neuroscience

Background:

• The clock drawing test is a standard tool for adult neuropsychological assessment.
• Its application in pediatric populations requires understanding developmental trajectories.

Purpose of the Study:

• To investigate the developmental progression of clock face drawing in typically developing children aged 6 to 12 years.
• To assess the development of time conceptualization and clock construction skills.

Main Methods:

• Utilized an adapted scoring system to evaluate clock face drawings.
• Assessed children aged 6 to 12 years on time conceptualization and clock construction.

Main Results:

• Children showed improved time concepts by age 8 and clock construction by age 12.
• Number reversals were more common in left-handers but resolved by age 7.
• Left visuospatial neglect in the upper quadrant was observed in younger children (6-7 years) but not older ones (by age 8).

Conclusions:

• Clock face drawing development in children parallels frontal lobe maturation.
• Findings suggest visuospatial neglect in this context is linked to planning deficits, not true visuospatial impairment.
• Clock drawing is a valuable tool for assessing pediatric neuropsychological development.
