Using "Yuk!" to teach children new morals
Some morals - such as it being wrong to hurt others - children learn because they see the distress a particular behaviour causes others, or the harm it can bring upon themselves. But other immoral behaviours don't necessarily have obvious victims.
A new study discussed on our Research Digest suggests children are primed to recognise the immorality of certain behaviours by feelings of disgust and beliefs about unnaturalness, especially when these factors are combined.
