My research questions include:

 

The development of sociomoral evaluation

How do young humans make sociomoral evaluations based on their observation of others' social interactions? What factors are related to their sociomoral evaluations? To address the above questions, I have joined the Manybabies4 project, a large-scale, closely coordinated, multi-site replication study of infants’ preferences for prosocial characters (Hamlin et al., 2007). I am leading one spin-off project of ManyBabies4 with Kelsey Lucca, Hilal Sen, Francis Yuen, and Kiley Hamlin. This spin-off project aims to examine the sources of individual differences in infants’ sociomoral evaluations across cultures, such as parental moral language and parental justice sensitivity (see our OSF pre-registration). Currently 26 labs from 15 countries have pledged to collect data from 500 infants (with recruitment ongoing).

Children's selective responses toward prosocial and antisocial others

How do children respond differently toward prosocial and antisocial others? Previous studies found that children are less likely to help and more likely to punish antisocial others than prosocial others. I extended previous findings and examined children's selective empathy toward antisocial and prosocial others. I focused on three components of empathy: emotional sharing (e.g., feeling sad when seeing others feeling sad), perspective taking (i.e., understanding others’ feelings), and empathic concern (i.e., concern about sufferers, including the motivation to alleviate their pain).

Social cognitive and emotional correlates of moral behaviors

What social cognitive and emotional abilities are related to children's moral behaviors? Can children's prosocial behaviors and antisocial behaviors be predicted by their abilities, such as theory of mind (i.e., understanding others' mental states) and emotional empathy (i.e., sharing others' feelings)?

Genetic foundations of morality

What genes are related to moral behavior and moral judgment? How do genes interact with the environment to influence moral behavior and moral judgment? I proposed the “gene-hormone-brain-psychology-behavior” model to explain the pathways from genetic variation to moral performance.
