在各种临床和研究设置中，取消任务已广泛用于神经学评估选择性注意和视觉搜索。然而，关于阵列条件差异对前额叶皮层（PFC）脑活动的影响及其与发育特征的关联，仍然缺乏证据。本研究采用取消任务来研究不同阵列条件对氧合血红蛋白（oxy-Hb）浓度的影响。基于不同阵列条件（即结构化阵列与随机阵列）的双块设计类型的取消任务，对24名健康成人的数据进行了分析。根据正确回答的数量、错误回答的数量、命中率和表现分数（PS）来评估成绩；同时用近红外光谱检测PFC活性。此外，使用ADHD评定量表- iv （ADHD- rs - iv）评估注意缺陷/多动障碍（ADHD）的特征。结果显示，在随机数组中，正确答案的数量和PS更高，但错误答案和命中率没有差异。同样，我们观察到PFC中的氧- hb浓度在任务期间显着增加。此外，在结构化数组中，任务表现与ADHD特征之间存在显著的关系，而在随机数组中则没有。我们关于上述氧血红蛋白浓度变化的结果表明，PFC区域参与了选择性注意。我们还发现，在结构化数组中取消任务可能有助于评估ADHD的特征。
Cancelation tasks have been widely used to neurologically assess selective attention and visual search in various clinical and research settings. However, there is still a lack of evidence regarding the effect of differences in array conditions on brain activity in the prefrontal cortex (PFC) and its association with developmental characteristics. This study employed cancelation tasks to investigate the effects of varying array conditions on oxygenated hemoglobin (oxy-Hb) concentrations. Data from 24 healthy adults were analyzed based on performance during two-block-design type of cancelation tasks with different array conditions (i.e., structured array vs. random array). Performance was assessed based on the number of correct responses, incorrect responses, hit ratios, and performance scores (PS); while PFC activity was examined using near-infrared spectroscopy. In addition, characteristics of attention-deficit/hyperactivity disorder (ADHD) were assessed using the ADHD-Rating Scale-IV (ADHD-RS-IV). Results revealed that the numbers of correct responses and PS were higher in the random array, but there was no difference in the incorrect responses and hit ratio. Similarly, we observed that the oxy-Hb concentration in the PFC significantly increased during the task. Additionally, in the structured array, a significant relationship between task performance and characteristics of ADHD was found but not in the random array. Our results regarding the above-mentioned changes in oxy-Hb concentration suggest that the PFC region is involved in selective attention. We also found that cancelation tasks in a structured array may be useful in evaluating the characteristics of ADHD.
