To compare the effect of motivational features on sustained attention in children born very preterm and at term.
EEG was recorded while 34 8-to-11-year-old children born very preterm and 34 term-born peers completed two variants of a cued continuous performance task (CPT-AX); a standard CPT-AX with basic shape stimuli, and structurally similar variant, with a storyline, familiar characters, and feedback.
Higher hit rates, quicker response times and larger event-related potential (ERP) amplitudes were observed during the motivating, compared with the standard, task. Although groups did not differ in task performance, between-task differences in ERPs associated with orienting were larger in term-born than very preterm children.
The findings add to previous evidence of disruption to the brain networks that support salience detection and selective attention in children born preterm. Manipulations that increase intrinsic motivation can promote sustained attention in both term-born and very preterm children.
比较动机特征对极早产儿和足月儿持续注意力的影响。
在34名8至11岁的极早产儿和34名足月儿同伴完成线索连续性能任务（CPT-AX）的两个变体时记录脑电图；一个是带有基本形状刺激的标准CPT-AX，另一个是结构相似的变体，带有故事情节、熟悉的角色和反馈。
与标准任务相比，在有动机的任务中观察到更高的命中率、更快的反应时间和更大的事件相关电位（ERP）振幅。虽然两组在任务表现上没有差异，但与定向相关的ERP在任务间的差异在足月儿中比极早产儿更大。
这些发现进一步证明了早产儿童支持显著性检测和选择性注意力的脑网络受到破坏。增加内在动机的操作可以促进足月儿和极早产儿的持续注意力。
