Absent-mindedness: failure of attention during retrieval or encoding.
Blocking: inability to retrieve previously stored information, "tip of the toungue" phenomenon.
Sins of distortion
Misattribution: failure of source memory, when incorrect source is identified and when it is not.
Suggestibility: influence that things like question phrasing can have on memory. Manifestation of misinformation.
Bias: largely the consistency bias, in which people overestimate the similarity between their current and previous attitudes, allowing their present state alter past memories.
Sin of intrusion
Persistence: inability to forget the things we most want to. Cause of problems like post-traumatic stress disorder.
