Abstract

A witness's relationship with a defendant is frequently discussed in criminal trials, yet investigations into perceptions of this relationship have been scarce. Further, an exploration of witnesses other than eyewitnesses has been missing from the literature. The present studies explored how witness type and familiarity with a defendant impact the perceived credibility of a witness. In Study 1, a familiar earwitness was perceived as more credible and honest than a stranger earwitness but the same was not found for eyewitnesses. Results from Study 2 suggest an eyewitness was seen as more credible and believable than an earwitness, and that a familiar witness was seen as more reliable than a stranger, but not than an acquaintance. There was no impact of familiarity or witness type on legal decisions. The present studies indicate that the prior definitions of familiarity might only capture a restricted range of potentially familiar relations.

Keywords: Earwitness; eyewitness; familiarity; perceived credibility; witness type.
