研究假设，临床确诊为感觉调节障碍(SMD)的儿童对感觉有非典型的生理反应，这种反应将预测父母报告的对感觉的行为反应。检查了19名临床确诊为精神障碍的儿童，年龄3-9岁，平均6.0岁，以及19名年龄和性别匹配的健康(对照组)儿童，年龄3-9岁，平均6.6岁。受试者被呈现了五种刺激。每种刺激都进行了10次试验，并记录了儿童的皮肤电活动。4名SMD儿童对刺激没有表现出电皮肤反应(EDR)；所有对照儿童都有反应。排除无反应者，患有SMD的儿童比对照组儿童表现出更多和更大的EDR。有干扰的参与者习惯于重复刺激的速度更慢，这是通过对刺激的反应数量和引起反应的刺激的比例来衡量的。患有非典型EDR的儿童有更多父母报告的对感觉的异常行为反应。临床确诊为SMD的儿童对感觉刺激的生理反应与一般发育中的儿童不同；这些差异对功能行为有影响。
It was hypothesized that children clinically identified with sensory-modulation disruptions (SMD) would have atypical physiological responses to sensation, and that such responses would predict parent-reported behavioral responses to sensation. Nineteen children with clinically identified disruptions, aged 3 to 9 years, mean 6.0 years, and 19 age- and sex-matched healthy (control) children, aged 3 to 9 years, mean 6.6 years, were examined. The subjects were presented with five stimuli. Ten trials were conducted for each stimulus and the electrodermal activity of the child was recorded. Four children with SMD did not show electrodermal responses (EDR) to stimulation; all control children responded. Excluding non-responders, children with SMD showed more and larger EDR than control children. Participants with disruptions habituated more slowly to repeated stimulation, as measured by the number of responses to stimuli and proportion of stimuli that evoked responses. Children with atypical EDR had more parent-reported abnormal behavioral responses to sensation. Children with clinically identified SMD respond physiologically differently to sensory stimuli than typically developing children; these differences have ramifications for functional behavior.
