Abstract:
Objective:To explore the modulating effect of match-type of reward on social attention in children with autism spectrum disorder (ASD).Methods:From August 2023 to September 2024, twenty children with ASD and twenty typical development (TD) children peers matched to age, gender and intelligence were recruited from several rehabilitation institutions and a primary school in Hefei, Anhui province, and participated in the experiments. All children with ASD were assessed by autism behavior checklist (ABC). All children completed the reward learning task, reward learning test and visual search training on the first day and the visual search test on the second day. SMI-red eye tracking system was used to collect the children's eye tracking features. Two-way analysis of variance and t-test were utilized to examine search time and search accuracy rate using SPSS 26.0 and GraphPad Prism 8 softwares. Results:All children successfully passed the reward learning test.However, the accuracy of children with ASD was significantly lower than TD peers (96.68% vs 99.32%, Z=2.25, P<0.05). In visual search training, both ASD and TD children spent less time searching the high-reward face than the low-reward face (ASD children: (484.67±136.80)ms vs (527.09±126.90)ms, t=-2.56, P=0.02, TD children: (453.82±176.17)ms vs (511.66±187.14)ms, t=-3.41, P<0.01). During the visual search test, enhanced attention capture were observed in both groups when singleton distractor matched with high reward characteristics compared to the low reward(feature-match: ASD children(451.82±121.13)ms vs (511.67±134.99)ms, t=-2.51, P=0.02; TD children(364.79±92.83)ms vs (465.53±146.95)ms, t=-4.22, P<0.01. Relation-match: ASD children(513.67±215.03)ms vs (446.53±148.00)ms, t=-2.22, P=0.04, TD children(464.00±194.55)ms vs (410.58±184.47)ms, t=3.93, P<0.01). Conclusion:The feature-match relationship can regulate the social attention of children with ASD.
