A neural network model of implicit memory for object recognition

People name well-known objects shown in pictures more quickly if they have studied them previously. The most common interpretation of this priming eff ect is that processing is facilitated by an implicit memory trace in a perc eptual representation system. We show that object priming can be explained instead as a bias in information processing, without recourse to an implici t memory system assumptions about psychological decision-making processes a nd bias were added to a neural network model for object identification, and the model accounted for performance both qualitatively and quantitatively in four object identification experiments.
