Are children from “Eastern” cultures less emotionally expressive and reactive than children from “Western” cultures? To answer this, we used a multi‐level and multi‐contextual approach to understand variations in emotion displays and cortisol reactivity among preschoolers living in China and the United States. One hundred two preschoolers from China (N = 58; 55% males) and the United States (N = 44, 48% males) completed three (i.e., control, interpersonal‐related, and achievement‐related) emotion‐challenging paradigms over 3 days. Behavioral emotion expressions were coded, and salivary cortisol was sampled 30 minutes before and across 90 minutes post‐task. Without considering context, Chinese preschoolers displayed fewer levels of positive and negative emotion expressions relative to their United States counterparts. However, Chinese preschoolers displayed similar levels of expressions as their United States counterparts during an achievement‐related challenge that is more salient to their sociocultural emphases and showed higher negative emotion expressions in this challenge, relative to other contexts. Moreover, only the achievement‐related challenge elicited increased cortisol levels among Chinese preschoolers, and this was correlated with higher levels of negative expressions. For US preschoolers, no cortisol increase was observed in any challenging paradigms, nor was cortisol associated with emotional expressions. Findings counter prior notions that East Asian children are generally less emotionally expressive. Instead, an achievement‐related challenge elicited higher emotion expression and cortisol reactivity among Chinese preschoolers, suggesting that children's emotion expression and biological reactivity may be most responsive to contexts salient to their socio‐cultural environments. We discuss the importance of considering cultural contexts when studying emotion regulation. Research Highlights Chinese preschoolers displayed lower overall positive and negative expressions relative to their US counterparts without considering situational contexts. Chinese preschoolers displayed similar levels of emotion expressions as their US counterparts during an achievement‐related challenge salient to their social‐cultural environment. Chinese preschoolers are particularly responsive to achievement‐related challenges, relative to other emotion‐challenging situations that are less culturally salient. No cortisol increase was observed in any of the emotion‐challenging paradigms among US preschoolers. Children's emotion expression and biological reactivity may be most responsive to challenges relevant to their socio‐cultural environments.
