  Moral psychology explores the psychological foundations and processes involved in moral behavior. It is an empirical science that studies how humans think and act in moral contexts. It is interested in how moral reasoning and judgments take place, how moral character forms, what sensitivity people have to moral evaluations, and how people attribute and react to moral responsibility.
  
  One of its key topics is moral development or the question of how morality develops on a psychological level from infancy to adulthood. According to Lawrence Kohlberg, children go through different stages of moral development as they understand moral principles first as fixed rules governing reward and punishment, then as conventional social norms, and later as abstract principles of what is objectively right across societies. A closely related question is whether and how people can be taught to act morally.
  
  Evolutionary ethics, a closely related field, explores how evolutionary processes have shaped ethics. One of its key ideas is that natural selection is responsible for moral behavior and moral sensitivity. It interprets morality as an adaptation to evolutionary pressure that augments fitness by offering a selective advantage. Altruism, for example, can provide benefits to group survival by improving cooperation. Some theorists, like Mark Rowlands, argue that morality is not limited to humans, meaning that some non-human animals act based on moral emotions. Others explore evolutionary precursors to morality in non-human animals.
