Habituation has an important role in attention. By reducing one's sensitivity to a constant source of stimulation, it frees up attention resources to process new distinct items. Impaired habituation may disrupt sustained attention via inability to modulate the repeated intrusion of irrelevant stimuli.
Using Troxler fading, this study investigated habituation to peripheral stimuli in adults with ADHD. A total of 41 adults (21 ADHD and 20 controls) participated in the study.
Adults with ADHD were slower to habituate to peripheral stimuli.
The findings suggest that impaired habituation may explain the clinical symptoms associated with adult ADHD.
习惯化在注意力中起着重要作用。通过降低对恒定刺激源的敏感性，它可以释放注意力资源来处理新的不同项目。习惯化受损可能会通过无法调节无关刺激的反复入侵来破坏持续注意力。
本研究使用 Troxler 褪色法研究了 ADHD 成人对外周刺激的习惯化。共有 41 名成年人（21 名 ADHD 和 20 名对照组）参加了这项研究。
ADHD 成人对外周刺激的习惯化较慢。
研究结果表明，习惯化受损可能解释了与成人 ADHD 相关的临床症状。
