Emotional expressions influence memory by both impairing and enhancing attention and perception at encoding, consolidation and recall. In three studies we compare angry, happy and fearful emotional prosodies using a single-word presentation paradigm, and investigate the effects of emotional vocal expressions on immediate and delayed recall for central emotional items and their periphery. Overall the results support a prosody-induced emotional enhancement of memory, as well as a memory facilitation for the periphery of specific emotions. The fact that emotional enhancement of memory by prosody was replicated in three studies suggests a robust effect, which to our best knowledge has not been observed before with vocal expressions.
