Hypothesis
Do attentional and inhibitory processing deficits in adults with ADHD share familial influences with ADHD in children?
Conclusion
The study found evidence for familial associations of attentional and inhibitory processes with ADHD in adults.
Supporting Evidence
- Fathers of children with ADHD showed weaker attentional orienting and inhibitory processing compared to controls.
- ADHD participants had significantly longer reaction times and increased variability compared to controls.
- ERP measures indicated significant differences between fathers and controls in attentional and inhibitory processes.
Takeaway
This study looked at how fathers of children with ADHD and adults with ADHD pay attention and control their impulses, finding that these traits can run in families.
Methodology
The study compared event-related potentials in 20 fathers of children with ADHD, 21 adults with ADHD, and 20 controls during a cued continuous performance task.
Potential Biases
Potential selection bias as parents with higher ADHD symptoms may be less likely to participate.
Limitations
The sample size was relatively small, which may limit the power to detect familial effects.
Participant Demographics
Participants included 21 male adults with ADHD, 20 fathers of children with ADHD, and 20 male healthy controls, aged 18 to 56.
