Children with traumatic brain injury are reported to have deficits in performance monitoring, but the mechanisms underlying these deficits are not well understood. Four performance monitoring hypotheses were explored by comparing how 28 children with traumatic brain injury and 28 typically developing controls (matched by age and sex) performed on the stop-signal task. Control children slowed significantly more following incorrect than correct stop-signal trials, fitting the error monitoring hypothesis. In contrast, the traumatic brain injury group showed no performance monitoring difference with trial types, but significant group differences did not emerge, suggesting that children with traumatic brain injury may not perform the same way as controls.
据报道,创伤性脑损伤儿童在执行监控方面存在缺陷,但这些缺陷背后的机制尚未得到充分理解。通过比较28名创伤性脑损伤儿童和28名发育正常的对照组儿童(按年龄和性别匹配)在停止信号任务中的表现,探讨了四种执行监控假设。对照组儿童在错误的停止信号试验后比正确的试验中显著放慢速度,符合错误监控假设。相比之下,创伤性脑损伤组在不同试验类型中未表现出执行监控差异,但未出现显著的组间差异,这表明创伤性脑损伤儿童的表现可能与对照组不同。
