Separating item-related electrophysiological indices of retrieval effort and retrieval orientation

The relationship between two classes of retrieval process—retrieval orientation and retrieval effort—was investigated using electrophysiological (ERP) and behavioural measures. ERPs were recorded during retrieval phases of exclusion tasks in which participants focused on retrieval of either phonolog...
