J. Nolan et R. Markham, THE ACCURACY-CONFIDENCE RELATIONSHIP IN AN EYEWITNESS TASK - ANXIETY AS A MODIFIER, Applied cognitive psychology, 12(1), 1998, pp. 43-54
The present study investigated the role of anxiety as a moderator of t
he relationship between accuracy and confidence in an eyewitness recal
l task. Participants selected as high or low anxious on a test anxiety
scale viewed a video clip of a crime. One week later they answered ve
rbally a series of questions about the video, rating their confidence
in each answer. Observers were shown a video-recording of each partici
pant's test session and rated how confident they appeared overall. It
was argued that people high in test anxiety would appraise their perfo
rmance to a greater degree than low-anxious people, resulting in a sig
nificant correlation between accuracy and subjective confidence for hi
gh-anxious but not for low-anxious participants. The results obtained
supported this hypothesis, and found similar relationships between acc
uracy and perceived confidence. Highly anxious participants expressed
less overall confidence in their answers than low anxious participants
