OBJECTIVES
Previous studies have widely demonstrated that inhibition of return (IOR) with audiovisual targets decreases due to audiovisual integration (AVI). It is currently unclear, however, whether the impaired AVI in children with ADHD has effects on IOR. The present study used the cue-target paradigm to explore differences between the IOR of audiovisual targets and the IOR of visual targets in ADHD and typically developing (TD) children.
METHOD
A total of 81 native Chinese speakers aged 6 to 13 years were recruited, including 38 children with ADHD and 43 age- and sex-matched TD children.
RESULTS
The results showed that there was a smaller magnitude of IOR with audiovisual targets as compared with visual targets in the two groups. Importantly, the reduction of IOR in audiovisual conditions was significantly smaller in children with ADHD than in children with TD. Race model analyses further confirmed that differences in IOR between ADHD and TD are due to deficits of audiovisual integration in ADHD.
CONCLUSION
The results indicated that children with ADHD have impaired audiovisual integration, which has a minimal impact on IOR.
目的
先前的研究广泛表明，由于视听整合（AVI），视听目标的返回抑制（IOR）会降低。然而，目前尚不清楚 ADHD 儿童的 AVI 受损是否会对 IOR 产生影响。本研究采用线索-目标范式，探讨 ADHD 和正常发育（TD）儿童视听目标的 IOR 与视觉目标的 IOR 之间的差异。
方法
共招募了 81 名母语为汉语、年龄在 6 至 13 岁之间的受试者，其中包括 38 名 ADHD 儿童和 43 名年龄和性别匹配的 TD 儿童。
结果
结果表明，两组儿童的视听目标的 IOR 幅度均小于视觉目标的 IOR。重要的是，与 TD 儿童相比，ADHD 儿童在视听条件下 IOR 的减少幅度明显较小。种族模型分析进一步证实，ADHD 和 TD 之间的 IOR 差异是由于 ADHD 中的视听整合缺陷所致。
结论
研究结果表明，ADHD 儿童的视听整合受损，这对 IOR 的影响最小。
