Performance patterns in Conners' CPT among children with attention deficit hyperactivity disorder and dyslexia. | LitMetric

AI Article Synopsis

  • The study evaluated the performance of 52 children with ADHD and 32 children with dyslexia using the Conners' Continuous Performance Test (CCPT) to compare them against a normative Brazilian sample.
  • Results showed that children with ADHD generally performed worse than the normative group, while children with dyslexia exhibited higher scores in specific areas like commissions and variability.
  • The ADHD and dyslexia groups displayed distinct patterns; ADHD kids struggled more with omissions, while dyslexia kids had issues with responding to non-target stimuli and showed increased reaction time variability as the test went on.

Article Abstract

This study investigated the performance of children with attention deficit hyperactivity disorder (ADHD) and dyslexia using Conners' Continuous Performance Test (CCPT). The clinical groups were composed of 52 children with ADHD and 32 children with dyslexia. Performance in the CCPT was evaluated using ANCOVA to compare the clinical groups with the normative Brazilian sample. The ADHD group performed worse than the normative sample in almost all of the measurements, except for reaction time and response style. The dyslexia group scored higher on commissions, variability, perseverations and inconsistency in the reaction time over the six time blocks (Hit SE Block Change) than the children in the normative Brazilian sample. The ADHD and dyslexia groups differed in omission measurements, Hit RT SE, variability, perseverations, Hit RT Interstimulus Intervals (ISI) Change and Hit SE ISI Change. We thus found that the dyslexia group had specific deficit patterns, with greater response to non-target stimuli, greater perseveration and response variability, and difficulties in hit reaction time as the test progressed.
