目的/目标：本研究考察了脑瘫儿童和非脑瘫儿童在两个检查时间（IT）测试中的表现，作为认知处理速度的无障碍非快速反应措施。研究方法/设计：参与者，年龄8至16岁，包括66名先天性CP儿童和119名正常发育的同龄人。措施是两个视觉IT任务相同的目标刺激，但不同的反应策略，无论是通过传统的双键方法或与辅助技术压力开关接口和响应选项扫描。结果：CP组的IT比对照组慢，与测试版本无关。对数转换用于解决偏斜，转换后的平均组内相关性显示两个参与者组的测试版本之间存在中度一致性。Bland-Altman图显示，在平均IT阈值较高时，观察到测试版本评分之间的差异较大。结论/影响：研究结果支持开发测试，减少快速运动反应的需求的可行性。未来的测试开发应在神经心理功能的极端情况下增加难度等级，以更准确地评估与非典型表现水平相关的个体的表现。
Purpose/Objective: This study examined the performance of children with and without cerebral palsy on two inspection time (IT) tests, as accessible nonspeeded response measures of cognitive processing speed. Research Method/Design: Participants, ages 8 to 16, included 66 children with congenital CP and 119 typically developing peers. Measures were two visual IT tasks with identical target stimuli but differential response strategies either via a traditional dual-key method or with an assistive technology pressure switch interface and response option scanning. Results: The CP group had slower IT than the control group independent of test version. Log transformations were used to address skew, and transformed mean intraclass correlations showed moderate agreement between test versions for both participant groups. Bland-Altman plots showed that at higher mean IT thresholds, greater discrepancies between test version scores were observed. Conclusions/Implications: Findings support the feasibility of developing tests that reduce speeded motor response demands. Future test development should incorporate increased gradations of difficulty at the extremes of neuropsychological functioning to more accurately assess the performance of individuals whose conditions are associated with atypical performance levels.
