Cognitive screening for children and adolescents: general limits or ceiling effects?

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Science

Background:

• Cognitive screening tools for children may have limitations when used with adolescents.
• An apparent "ceiling effect" in scores around age 10-11 has been observed.
• This ceiling effect may stem from material limitations or a true cognitive limit.

Purpose of the Study:

• To investigate the "ceiling effect" in cognitive screening tools for children and adolescents.
• To determine if the ceiling effect is due to test materials or a genuine limit in general cognitive development.
• To adapt and validate the School-Years Screening Test for the Evaluation of Mental Status (SYSTEMS) for a broader age range.

Main Methods:

• Utilized a modified School-Years Screening Test for the Evaluation of Mental Status (SYSTEMS) with more challenging items.
• Recruited 85 participants aged 10–15 years.
• Compared results with a database of 1249 children aged 4–12 years.

Main Results:

• Cognitive screening scores increased rapidly in younger children.
• Scores tended to reach a maximum in early adolescence, forming an asymptotic curve.
• This asymptotic pattern explained a significant portion of the score variance.

Conclusions:

• General cognitive screening has an upper limit in early adolescence, despite continued development of specific functions.
• The study supports the use of cognitive screening tools across a wide age range.
• Findings suggest implications for research and clinical applications in cognitive assessment.
