Objective To explore whether there is a reward value effect in children with hearing impairment,and examine the impact of reward-guided attention on visual working memory in these children.Methods Thirty children with hearing impairment and 30 normal children were selected as participants.The change perception task paradigms,including sequential presentation and overall presentation,were used to analyze changes in recall accuracy and reaction time under different reward guidance.Results In the sequential presentation of memory items,the main effect of series position on recall accuracy was significant(P<0.001),with item recall accuracy at position 4 being higher than those at positions 1,2,and 3,and item recall accuracy at position 3 being higher than those at positions 1 and 2.The interaction between reward types and series positions during recall reaction was significant(P=0.009).When the rewards were the same,the recall reaction time at position 4 was shorter than that at position 3.When the rewards were different,the recall reaction time at positions 3 and 4 was shorter than that at position 1.In the overall presentation of memory items,the main effect of recall accuracy for different types of subjects was marginally significant(P=0.069),and the recall accuracy of children with hearing impairment was lower than that of normal children.The main effect of participant type on recall reaction time was marginally significant(P=0.099),and children with hearing impairment had more recall reaction time than normal children.Conclusion Both children with hearing impairment and normal children exhibit a recency effect,but neither group shows a reward value effect.
