Motor Imagery Development in Children: Changes in Speed and Accuracy With Increasing Age

Area of Science:

• Neuroscience
• Developmental Psychology
• Motor Control

Background:

• Motor imagery is a key cognitive process with potential applications in pediatric rehabilitation.
• Limited research exists on the developmental trajectory of motor imagery abilities throughout childhood and adolescence.
• Understanding when children's motor imagery performance converges with adult levels is crucial for effective intervention design.

Purpose of the Study:

• To investigate the developmental progression of motor imagery skills in typically developing children and adolescents.
• To determine the age at which motor imagery performance in children becomes comparable to that of adults.
• To analyze the influence of age on accuracy and reaction time in a mental rotation task assessing motor imagery.

Main Methods:

• A mental rotation task was administered to 164 typically developing children and adolescents across four age groups (6-7, 8-9, 10-11, 12-13 years) and 30 adults.
• The study analyzed the effects of biomechanical constraints, accuracy, and reaction time on task performance.
• Analysis of Variance (ANOVA) was used to compare performance across age groups.

Main Results:

• All age groups demonstrated the influence of biomechanical constraints on the mental rotation task.
• Significant group effects were observed for accuracy and reaction time (p < 0.001).
• Children aged 6-7 and 8-9 years showed significantly lower accuracy and slower reaction times compared to older groups and adults (p < 0.05).
• No significant differences in accuracy or reaction time were found between children aged 10-11 and 12-13 years and adults (p > 0.05).

Conclusions:

• Motor imagery is present in children as young as 6-7 years.
• Motor imagery capabilities show a developmental improvement with increasing age throughout childhood and adolescence.
• Children aged 10 years and older exhibit motor imagery performance comparable to adults.
