Abstract / Bemerkung
While several computational models have suggested how predictive coding could be implemented on an algorithmic level, reference to cognitive processes remains rather sparse. A crucial process might be elevating relevant prior information from long-term memory to render it highly accessible for subsequent comparison with sensory input. In many models, visual short-term memory (VSTM) is considered as information from long-term memory in a state of elevated activity. We measured the BOLD signal in face-specific cortical areas using repetition suppression (RS) paradigm. RS has been associated with predictive processing in previous studies. We show that RS within the fusiform face area is significantly attenuated when VSTM is loaded with other, non-facial visual information. Although an unequivocal inference is not possible, the data indicate a role of VSTM for predictive processes as indexed by expectation-related RS.
