Objective To explore the influence of different callers on response to name among infants with autism spectrum disorders (ASD). Methods Totally 72 ASD,36 developmental delays (DD) and 36 neuro-typical (NT) infants aged 16 to 30 months,were recruited from Child Developmental and Behavioral Center and near communities from April 2017 to February 2018.Response to name contained two main procedures: the tester procedure and the caregiver procedure.Behavioral data were collected by cameras,coded by two professional staffs,and compared among three groups. Results The difference of response rate between the tester procedure and the caregiver procedure in DD group was significant (Z=-5.01,P<0.01); While the differences on response rate in ASD and NT group,the differences on response score,response time,and response duration time among three groups were not significant(P>0.05).Moreover,there were significant differences on the proportion of responsive infants in both ASD and non-ASD group between single caller procedure and the total procedures (χ2=11.15,9.06,11.39,10.23,all P<0.01). Conclusion Although there was no significant response preference for caregivers among all group infants,subjects' name called by testers and caregivers respectively could effectively reduce the response bias in response to name procedures.
