| summary | Although textbook descriptions suggest that semantic and episodic memory are associated with clearly distinct content and subjective experience, different patterns of impairment in neuropsychological patient studies, and distinct brain activations in neuroimaging studies, data collected in recent years suggest a more complex pattern. At the behavioural level, few existing memory tests allow well-matched comparisons between semantic and episodic memory performance. Moreover, most tests of naturalistic human memory require participants to recall episodic memories, and interpretation of retrieved semantic details often poses difficulties. I will discuss newly developed memory measures that circumvent some of these issues, including a new version of the autobiographical interview. I will also mention studies of patients with adult-onset amnesia, using experimental designs and test items that provide good sensitivity to subtle impairment, that demonstrate parallel impairment of semantic and episodic memory. Finally, recent neuroimaging evidence suggests that the neural correlates of semantic and episodic memory retrieval demonstrate remarkable overlap. Two possible explanations for this overlap will be discussed. First that activity of some, or possibly all, regions belonging to the episodic recollection network may support the reinstatement of semantic processes engaged as an episode was first experienced. Second, that semantic and episodic memory rely on different weightings of some of the same elementary processes, such as sensory-perceptual imagery, spatial and temporal features, and self-reflection. |
