Summary

The main aim of the present study is to investigate the effects of orally administered vasopressin (AVP) on the perception of time-to-collision of threatening and non-threatening stimuli by combining a validated looming fear eye-tracking paradigm with a randomized between-subject placebo-controlled pharmacological trial design.
