where attention and memory interface. Common errors of this type include misplacing keys or eyeglasses, or forgetting appointments. The reason is that at the time of encoding sufficient attention was not paid to the fact that place or time etc. would later need to be recalled. Absentmindedness means here that the person's attention is focussed on something different, and therefor misses part of the encoding. Blocking Blocking is when the brain tries to retrieve or encode information, but another memory interferes with it. Blocking is a primary cause of Tip of the tongue phenomenon (a temporary inaccessibility of stored information). Misattribution Misattribution entails correct recollection of information with incorrect recollection of the source of that information. For example, a person who witnesses a murder after watching a television program may incorrectly blame the murder on someone he or she saw on the television program. This error has profound consequences in legal systems because of its unacknowledged prevalence and the confidence which is often placed in the person's ability to impart correctly information critical to suspect identification. One example Schacter gives of eyewitness misattribution occurred in connection with the Oklahoma City bombing in 1995. Two days before, the bomber rented a van, but an employee there reported seeing two men renting it together. One description fit the actual bomber, but the other description was soon determined to be of one of a pair of men who also rented a van the next day, and were unconnected with bombing. Schacter also describes how to create misattribution errors using the DRM procedure. Subjects are read a list of words like sharp, pin, sewing, and so on, but not the word needle. Later subjects are given a second list of words including the word *needle*, and are asked to pick out which words were on the first list. Most of the time, subjects confidently assert that *needle* was on the first list. Suggestibility Suggestibility is somewhat similar to misattribution, but with the inclusion of overt suggestion. It is the acceptance of a false suggestion made by others. Memories of the past are often influenced by the manner in which they are recalled, and when subtle emphasis is placed on certain aspects which might seem likely to a specific type of memory, those emphasized aspects are sometimes incorporated into the recollection, whether or not they occurred. For example, a person sees a crime being committed
