讲座内容简介:

      Memory has long been conceived as a dynamic process. As Bartlett (1932) noted, “Remembering is not the re-excitation of innumerable fixed, lifeless and fragmentary traces, but rather an imaginative reconstruction or construction…”. In this talk, I will present our new recent work trying to understand the transformative nature of human episodic memory. First, I will show evidence that the reactivated representation during memory retrieval has been systematically transformed from the encoded representations. Second, I will present two recent studies which suggest that effective learning strategies, such as spaced learning and retrieval practice, often involves greater representational transformation. Finally, I will present our ongoing study using intracranial EEG to study the transformative nature of episodic memory, by the comparing the nature of neural representation during memory encoding, working memory and long-term memory.
