Abstract
Why do we trust each other? We carried out three experiments to test whether interpersonal trust depends on perceived self-other overlap. As previous studies suggest that enfacing (feeling ownership for, and include more into oneself of the face of) an avatar might make one trust this avatar more, we exposed participants to faces of ingroup and outgroup avatars that moved in synchrony or out of synchrony with the participant's own facial movements, and assessed the impact of synchrony on self-other overlap and trust measures. Experiment 1 used ingroup faces and successfully showed that synchrony (manipulated within-participants) increased self-other overlap and trust, which we assessed by means of the Trust Game and the Implicit Association Test (IAT). In Experiment 2, which used outgroup faces and a within-participants design, synchrony still increased scores in the Trust Game but the IAT was no longer affected. Experiment 3 replicated Experiment 2 but with synchrony varying between participants, which eliminated the synchrony effect in both trust measures. Importantly, Inclusion of Other in the Self (IOS) ratings were found to predict the IAT effect in synchronous conditions. Taken altogether, our findings suggest that interpersonal trust is mainly driven by perceived self-other overlap. Besides group identification, appearance, and voluntary movement, synchrony is just one of several sources contributing to perceived self-other overlap.
期刊介绍:
Promoting the interests of scientific psychology and its researchers, QJEP, the journal of the Experimental Psychology Society, is a leading journal with a long-standing tradition of publishing cutting-edge research. Several articles have become classic papers in the fields of attention, perception, learning, memory, language, and reasoning. The journal publishes original articles on any topic within the field of experimental psychology (including comparative research). These include substantial experimental reports, review papers, rapid communications (reporting novel techniques or ground breaking results), comments (on articles previously published in QJEP or on issues of general interest to experimental psychologists), and book reviews. Experimental results are welcomed from all relevant techniques, including behavioural testing, brain imaging and computational modelling.
QJEP offers a competitive publication time-scale. Accepted Rapid Communications have priority in the publication cycle and usually appear in print within three months. We aim to publish all accepted (but uncorrected) articles online within seven days. Our Latest Articles page offers immediate publication of articles upon reaching their final form.
The journal offers an open access option called Open Select, enabling authors to meet funder requirements to make their article free to read online for all in perpetuity. Authors also benefit from a broad and diverse subscription base that delivers the journal contents to a world-wide readership. Together these features ensure that the journal offers authors the opportunity to raise the visibility of their work to a global audience.
