q3 i? Adolescents with consistently high ADHD symptoms throughout childhood showed reduced N2 amplitude and longer SSRT at 17 years, while neither marker correlated with concurrent symptoms. → Einziger Tzlil 2021

Einziger Tzlil 2021¶

Einziger Tzlil, Ben-Shachar Mattan S., Devor Tali, Shmueli Michael, Auerbach Judith G., Berger Andrea. (2021). "My Brain Can Stop": An ERP Study of Longitudinal Prediction of Inhibitory Control in Adolescence. Brain Sciences, 11(1), 100. https://doi.org/10.3390/brainsci11010100

q3 · i? · associational · r2

Bivariate correlation analysis (Table 3) in the longitudinal sample. The article reports that N2 and SSRT "were significantly associated with ADHD symptoms throughout childhood"; no effect size is printed for these correlations.

"both were significantly associated with ADHD symptoms throughout childhood; those who had consistently high levels of ADHD symptoms throughout childhood showed reduced N2 amplitude (i.e., a less negative amplitude) and a longer SSRT at 17 years of age."

Discussion¶

Related Claims¶

• Higher inattention symptoms throughout childhood uniquely predict reduced adolescent N2 amplitude during successful inhibition, beyond hyperactivity-impulsivity symptoms — related
• Early precursors predict adolescent N2 directly, not indirectly through childhood inattention symptoms — related
• Adolescents in the lowest quartile of concurrent inattention symptoms show larger negative N2 amplitudes than the other three quartiles, with no linear concurrent correlation — related
• Total childhood ADHD symptoms predict longer adolescent SSRT, but neither symptom domain shows specificity and early precursors do not predict SSRT — related
