You rely on your memories for who you are as a person, where you have been, and what you have experienced in your life to date. But, what if it turned out that these memories that you hold closely aren't your memories at all? What if they were someone else's memories?This book documents the results of a research project investigating the effects of interpersonal relationship factors on shared reminiscence. Although memory and the factors that influence it have been researched more in recent years, there has been limited research which has measured the specific interpersonal effects of familiarity, trust, confidence, and memory esteem on memory distortion.There are four empirical chapters in this book. Within these four chapters are four separate, but related, studies, which examine the effects of interpersonal factors on memory distortion for ordinary events and for flashbulb memory of the terrorist attacks of September 11th, 2001.
