Size judgments are known to be influenced by existing knowledge. This provides a natural means for examining the interaction between prior knowledge and size judgments in recall memory tasks. We present results from a series of experiments that demonstrate the degree to which people use their prior knowledge to recall the size of studied objects. The results show that the participants remembered-size judgments regress towards the prior mean size of the object. We hypothesize that the reproduction of past stimuli can be decomposed into three components: prior knowledge, episodic trace, and noise in recall. Estimates for the relative contributions of these three factors are obtained through a Bayesian estimation procedure. |
