To explore the significance of repeated memories for individuals' personal histories, we compared the characteristics of young adults' unique and repeated memories of childhood experiences. Memory type (unique vs. repeated) was a within-participant variable. In Experiment 1, college-age participants generated as many early memories as possible in 4 minutes; in Experiment 2, another sample provided complete reports of five early memories in each condition. In both experiments, participants rated the vividness, biographical importance and personal meaning of each memory and labelled the accompanying emotion. Unique memories were more vivid than repeated memories as well as more likely to include negative emotion, regardless of the method of reporting. Most importantly, college students rated their memories for unique and repeated events as equivalently infused with personal meaning. Analysis of the content of the memories reported in Experiment 2 established that unique and repeated memories did not differ in word count or percentages of perceptual terms or words indicating positive affect, although unique memories contained a greater percentage of negative affect. Additional analyses of content provided evidence for differences in the functions served by unique and repeated memories. The results have implications for the study of autobiographical memory and for identifying over-general memories.Keywords: Autobiographical memory; Childhood; Life story; Repeated events; Unique events.Our lives largely comprise everyday events, and some of those events occur almost every day, at least for periods of time. Despite the extent to which repeated episodes constitute lived experience, they have traditionally been excluded from conceptualisations of autobiographical memory. For example, Nelson and Fivush (2004) define autobiographical memory as "an explicit memory of an event that occurred in a specific time and place in one's personal past" (p. 486). Recently, however, Rubin and Umanath (2015) have challenged the assumption that event memory must consist of unique episodes. They argue that some episodes are so similar that they are reported as a single scene at recall and that "the properties and construction of such repeated events overlap too heavily with those of unique events to be considered fundamentally different from them" (p. 10). In this paper, we contribute to the understanding of the similarities and distinctions between memories of unique versus repeated events, focusing particularly on the personal importance and content of these two categories of memories for childhood experiences. The examination of childhood memories allowed us to explore the extent to which memories of unique versus repeated events are available as influences on the self-concept and life story (Habermas & Bluck, 2000) at emerging adulthood.Consistent with Waters, Bauer, and Fivush (2014), we define unique memories as reports of past single events experienced by the participant at a particular time and place, and repeated memories as repr...
