Is Trouble Differentiating Emotions a Western Culture-Bound Syndrome Borne out of Colonisation?

Western individuals (US, UK) show poorer emotion differentiation than non-Western individuals (Russia, Japan) (Grossmann et al., 2016). In an Australian sample we aim to test whether self-reported and biological proximity to British and Western European culture predicts emotional neglect and poor emotional differentiation relative to Indigenous Australian and Japanese samples.
