Abstract: | Increasing recognition accuracy with repeated presentations was demonstrated for complex pictorial stimuli (real-world photographs) by accuracy, signal detection, and confidence of decision indicators. Consistent with other research, the effect occurred only for short stimulus durations. The effect occurred for both old and new pictures, the rate of improvement being greater for old than for new pictures. Experiment II utilized focus-degraded stimuli to demonstrate that amount of information artifacts were not responsible for the observed differences between responses to old and new pictures. |
