Specific memories were defined as events that had occurred within a distinct spatiotemporal context lasting less than 24 hours (e.g., \"My hips were aching Sunday from stretching\"). Overgeneral memories were defined as events extending beyond a single day (e.g., \u201cI've been relaxed the last three weeks\u201d), categories of repeated events (e.g., \u201cMy legs always become sore after playing squash\u201d), and general knowledge about the self or the world (e.g., \u201cI\u2019ve always been sensitive to pain\u201d). The researchers also timed how long it took participants to begin to generate each memory and coded the memories according to whether they were related or unrelated to surgery.<\/p>\n\n\n\n<p>\u201cThe number of specific memories the participants recalled before surgery predicted lower odds of reporting pain across all timepoints,\u201d says Waisman. \u201cAnd participants who took longer to recall memories in response to pain word cues before surgery, as well as those who generated more surgery-related content at the one-month postsurgical assessment, had greater odds of reporting postsurgical pain up to 12 months later.\u201d<\/p>\n\n\n\n<p>\u201cThese results tell us that the memory biases precede the development of chronic postsurgical pain, but we still don\u2019t know if they\u2019re causing it or simply correlated with it,\u201d says Katz, Canada Research Chair in Health Psychology at 快播视频 and the senior author of the study. \u201cThis is a critical issue because if the biases are causally related to the pain, we can begin to develop and apply memory interventions to people who are awaiting surgery to reduce the risk that acute postsurgical pain becomes chronic.\u201d<\/p>\n\n\n\n<p>Find the study <a href=\"https:\/\/journals.lww.com\/pain\/Abstract\/9900\/Autobiographical_memory_predicts_postsurgical_pain.47.aspx\"
