![]() Much less attention, both theoretical and empirical, has been paid to retrograde amnesia for another important type of memory content: general world knowledge. In particular, numerous studies of retrograde amnesia (impaired memory for previously-learned information) have explored losses of episodic (autobiographical) memory (e.g., Bayley et al., 2003 Rosenbaum et al., 2008) and in turn have led to specific proposals about how such information is encoded, retained, retrieved, and lost (e.g., Squire, 1992 Winocur and Moscovitch, 2011). The study of amnesic individuals has contributed to the development of theories about normal and impaired memory. Thus, losses that have already been well-documented (famous people and public events) may severely underestimate the nature of human knowledge impairment that can occur in retrograde amnesia. These results show that retrograde amnesia can involve broad and deep deficits across a range of general world knowledge domains. Across all domains tested, LSJ showed losses of knowledge at a level of breadth and depth never before documented in retrograde amnesia. We examined LSJ's knowledge across a range of everyday domains (e.g., sports) and domains for which she had premorbid expertise (e.g., famous paintings). LSJ is a professional artist, amateur musician and history buff with extensive bilateral medial temporal and left anterior temporal damage. To assess whether retrograde amnesia can also cause impairments to other forms of general world knowledge, we explored losses across a broad range of knowledge domains in a newly-identified amnesic. ![]() ![]() Those that have done so have focused primarily on memory for famous people and public events-relatively limited aspects of memory that are tied to learning during specific times of life and do not deeply tap into the rich and extensive knowledge structures that are developed over a lifetime. Studies of retrograde amnesia have focused on autobiographical memory, with fewer studies examining how non-autobiographical memory is affected. ![]()
