“…A majority of evidence (Hugenberg et al, 2011) showed that social categorization into in-group and out-group was sufficient to elicit the OGB, but a series of studies (Shriver et al, 2008;Van Bavel et al, 2008Ng et al, 2016Ng et al, , 2020Yan et al, 2017;Harrison et al, 2020;Fuller et al, 2021) have continued to report inconsistent results, especially when there were no salient physiognomic features on faces (same-race faces without other categorical diagnostic features). For example, some studies showed equivalent recognition memory for in-group versus out-group faces (Yan et al, 2017 for Chinese populations; Ng et al, 2016Ng et al, , 2020 for first-generation East Asian Canadians; Harrison et al, 2020 andFuller et al, 2021 for United Kingdom populations). In-/out-groups categorized by university membership which was a lack of competitive or rivalrous relationships did not elicit an own-group memory bias (Harrison et al, 2020;Fuller et al, 2021).…”
