What is the role of early visual cortices on the processing of facial trustworthiness?

In a new study in adult participants conducted by our collaborators in Maastricht, we investigated the role of early visual cortices for the processing of facial trustworthiness. To that end, processing in early visual cortices in adults was interrupted using so-called trans-cranial magnetic stimulation (TMS). Even when TMS was applied, participants showed comparable behavioural judgements of trustworthiness, suggesting that at least some aspects of facial trustworthiness can be processed without having to rely on early visual areas.
