A Note on the Stability of TAT Interjudge and Intrajudge Ambiguity Scores

Summary The stability of TAT ambiguity values, based either on interjudge, or intrajudge response variability, was investigated. Interjudge variability was estimated from dispersion of the first response emitted to each stimulus; intrajudge variability utilized multiple associations by Ss. Multiple association yielded highly stable values in comparisons over time, and neither method resulted in stability across S samples. It was concluded that the definition of ambiguity must include intrajudge variability in order to achieve a reliable ordering of stimuli for a given respondent.
