Objective To explore the effects of technoference on the quality of parent-child shared-book reading(SBR),and investigate the role of toddlers'gender in it.Methods An online anonymous questionnaire survey was conducted on mothers of toddlers aged 12 to 36 months,including demographic characteristics survey questionnaire,technology device interference scale(TDIS),and StimQ cognitive home environment questionnaire.A total of 307 valid questionnaires were obtained.Then the technoference levels,quality of parent-child SBR,and demographic characteristics were statistically analyzed.Results Correlation analyses showed that there was a significantly negative correlation between the technoference level and the quality of parent-child SBR,and the gender of toddlers played a moderating role between them.For boys,technoference significantly negatively predicted the quality of parent-child SBR,but this phenomenon was not evident in girls.Conclusion The negative impact of technoference on the quality of parent-child SBR is moderated by the gender of toddlers,with boys being more susceptible.
