A 2-year-old, it turns out, knows the difference between right and wrong. According to psychologist Judi Smetana, the sense of morality begins to develop early in humans. And by the time children are 3 to 4 years old, they recognize certain behaviors â such as hitting â as wrong, even when no one is watching, says Smetana, a professor at the University of Rochester.
Children at this age begin to understand and use âgender scripts.â This is another way to put things in categories. Instead of grouping things, they put events or activities in groups related to gender. For example, a five-year-old child may think that a person putting on make-up has to be a female.
