Self-conscious emotions, such as shame and guilt, play a fundamental role in regulating moral behavior and in promoting the welfare of the society. Despite their relevance, the neural bases of these emotions are uncertain. In the present meta-analysis, we performed a systematic literature review in order to single out functional neuroimaging studies on healthy individuals specifically investigating the neural substrates of shame, embarrassment and guilt. Seventeen studies investigating the neural correlates of shame/embarrassment, and seventeen studies investigating guilt brain representation met our inclusion criteria. The analyses revealed that both guilt and shame/embarrassment were associated with the activation of the left anterior insula, involved in emotional awareness processing, and arousal. Guilt specific areas were located within the left temporo-parietal junction, which is thought to be involved in social cognitive processes. Moreover, specific activations for shame/embarrassment involved areas related to social pain (dorsal anterior cingulate, insula, thalamus), behavioral inhibition (premotor cortex) networks. This pattern of results might reflect distinct action tendencies associated with the two emotions.

The first postpartum year is a period of elevated risk for experiencing psychological distress. Guilt and shame have been identified as significant predictors of other forms of psychological distress, such as anxiety and depression. However, guilt and shame are poorly distinguished in pre-existing literature. The current study used inductive thematic analysis to explore lived experiences of guilt and shame in the early postpartum period. All those interviewed had internalised unrealistic mothering ideals. Physical constraints on one’s parenting abilities, due to birth recovery, exacerbated postpartum guilt and shame. Other sources of guilt and shame included body dissatisfaction and making comparisons against other mothers and media depictions of motherhood. Participants were hesitant to confide in others about parenting challenges due to fears of judgement, which perpetuated the shame-concealment cycle. Future research should prioritise the development of interventions designed to target a harsh parenting inner critic, and the re-framing cognitive biases, to nurture more realistic and self-compassionate beliefs about motherhood. For practice, current findings mirror previous calls for intimate partners to be actively included in routine appointments, to provide healthcare practitioners with specialist training in postpartum mental health, and to educate mothers on responsible social media use.
