Emotion socialization aims to promote children's emotion competence. Children's competence is embedded in cultural contexts that influence caregivers' expectations of appropriateness of children's expression and experience of emotions. Two aspects of emotion competence -individualistic and relational emotion competence -are outlined. They offer a theoretical framework to interpret cultural commonalities and differences in emotion socialization strategies. This review summarizes current knowledge about caregivers' emotion socialization strategies toward children's negative emotional expressions and related behaviors in cultural perspective. The number of empirical studies in cultures outside of United States remains low. Nonetheless, the available evidence describes a range of emotion socialization strategies that are embedded in caregiving, and their consequences for children's emotion development. Besides several commonalities across cultures, we describe differences in the degree to which strategies are endorsed by caregivers as well as some of the qualitative information that point to cultural variations. Finally, we note gaps in the literature and suggest future research directions.

This study compared social looking and response to novelty in preschool-aged children (47-68 mo) with or without iron deficiency anemia (IDA). Iron status of the participants from a low-income community in New Delhi, India, was based on venous hemoglobin, mean corpuscular volume, and red cell distribution width. Children's social looking toward adults, affect, and wary or hesitant behavior in response to novelty were assessed in a semistructured paradigm during an in-home play observation. Affect and behavior were compared as a function of iron status: IDA (n = 74) vs. nonanemic (n = 164). Compared with nonanemic preschoolers, preschoolers with IDA displayed less social looking toward their mothers, moved close to their mothers more quickly, and were slower to display positive affect and touch novel toys for the first time. These results indicate that IDA in the preschool period has affective and behavioral effects similar to those reported for IDA in infancy.

Five-year-old Costa Rican children, who had either chronic, severe iron deficiency or good iron status in infancy, were observed with their mothers during a structured interaction task in a laboratory setting and everyday interactions in their home. Child affect and behavior as well as the quality of mother-child interaction of the formerly chronic iron-deficient children (n = 40) were compared to those with good iron status in infancy (n = 102). Children who had chronic iron deficiency in infancy were more likely to display lower levels of physical activity, positive affect, and verbalization during the structured task at 5 years, despite iron therapy that corrected their iron deficiency anemia in infancy. Mother-child reciprocity during the structured task (e.g., eye contact, shared positive affect, turn taking) was more likely to be lower in the chronic iron deficiency group compared to the good iron group. Mothers of children in the chronic iron deficiency group showed less responsivity in both settings. These results show that children with chronic, severe iron deficiency in infancy continue at behavioral disadvantage relative to their peers at school entry. Sustained differences in mother-child interaction might contribute to the long-lasting behavioral and developmental alterations reported in children with chronic, severe iron deficiency in infancy.

Children's books may provide an important resource of culturally appropriate emotions. This study investigates emotion displays in children's storybooks for preschoolers from Romania, Turkey, and the US in order to analyze cultural norms of emotions. We derived some hypotheses by referring to cross-cultural studies about emotion and emotion socialization. For such media analyses, the frequency rate of certain emotion displays can be seen as an indicator for the salience of the specific emotion. We expected that all children's storybooks would highlight dominantly positive emotions and that US children's storybooks would display negative powerful emotions (e.g., anger) more often and negative powerless emotions (e.g., sadness) less often than Turkish and Romanian storybooks. We also predicted that the positive and negative powerful emotion expressions would be more intense in the US storybooks compared to the other storybooks. Finally, we expected that social context (ingroup/outgroup) may affect the intensity emotion displays more in Turkish and Romanian storybooks compared to US storybooks. Illustrations in 30 popular children's storybooks (10 for each cultural group) were coded. Results mostly confirmed the hypotheses but also pointed to differences between Romanian and Turkish storybooks. Overall, the study supports the conclusion that culture-specific emotion norms are reflected in media to which young children are exposed.
