| Summary: | The Cognitive Interview is currently being used by various law enforcement agencies as
a credibility assessment tool. This research is designed to investigate whether there is utility in
using the CI in this way. Seventy-eight subjects were interviewed, each telling 2 stories, one true
and one false, and these stories were coded for various verbal content characteristics- number of
words, number of details, number of new details generated by the CI, filled pauses, repetitions,
subjective details, and references to the difficulty of the task. There was a significant difference
in the number of overall new details between the true and false accounts. There were more new
details (as a function of total number of words) for the true stories at least when the true stories
were told first. There were several interactions involving version and order for word count,
details, and new details, but no other significant findings for other coded clues to deception. The
findings suggest that the CI may be useful as a credibility assessment tool, however caution is
suggested before accepting its utility until further investigation is complete. === Arts, Faculty of === Psychology, Department of === Graduate
