Abstract

We present a novel way of accounting for similarity judgments.
Our approach posits that similarity ratings stem from three
main sources: familiarity, priming, and inherent perceptual
similarity. We present a process model of our approach in the
cognitive architecture ACT-R, and match our model’s predictions
to data collected from a human subject experiment which
involved simple perceptual stimuli. Familiarity accounts for
rising ratings over time; priming accounts for asymmetric effects
that arise when the stimuli are shown with different frequencies.
Pure perceptual similarity also predicts trends in the
results. Overall, our model matched the data with R2 of 0:99.
