Shame is a more complex emotion than disgust, because unlike disgust, shame is an inherently social emotion that depends on an awareness of social relationships before it can occur. It is impossible for a newborn baby to experience shame because a newborn has no concept of a social world yet. There’s just the baby’s needs and that is pretty much it. Only through gradual interaction, frustration and slow social-emotional development does a baby eventually realize that it is a separate being from other people. It is only after this realization of self as part of a web of social relationships that shame can occur.
