“…In a small study of American youth, youth’s stereotypes of teens as irresponsible in fulfilling family obligations during middle school were predictive of their problem behavior as they made the transition to high school, as well as changes in their bilateral ventrolateral prefrontal cortex activation during self-control, over and above a variety of potential confounds (Qu et al, 2018). In an experimental study with youth in middle school in a major city in Mainland China, youth experimentally induced to see teens as responsible subsequently had higher engagement in school and lower problem behavior than did their counterparts in the control condition (Qu et al, 2020). Given such findings, one reason problem behavior may be higher during adolescence in Hong Kong than Mainland China (e.g., Cheung et al, 2007; Zhang, 2008), with an increase over the middle school years (e.g., Shek & Lin, 2014, 2017; Shek & Zhu, 2018) in Hong Kong but not Mainland China (e.g., Liu, Zhang, Pan, Ma, & Lu, 2017; Liu et al, 2001), is that Hong Kong (vs. Mainland China) youth may view teens as more irresponsible.…”
